Will there be a global famine in 2050? Crops will be overwhelmed by pests in the next 30 years, scientists warn

Another of the "coming shortage" scares that Greenies often resort to, none of which have ever come true.  The scare below  is sheer speculation.  To prove spread they needed similar population counts at two different dates.  But they did not have that.  All they had was "historical observation dates" for a minority of their species.  Anyway, genetic engineering techniques are alrady reducing pest loads and should continue to do so.  That is why Greenies are trying to ban it

Many of the world's most important crop-producing countries will be fully saturated with pests by the middle of the century if current trends continue, a study has found.

More than one-in-ten pest types can already be found in around half the countries that grow their host crops.

And if this spread advances at its current rate, scientists fear that a significant proportion of global crop-producing countries will be overwhelmed by pests within the next 30 years.

The research from the University of Exeter was published in the journal Global Ecology and Biogeography.


Experiments by British academics have found that GM insects could be used to wipe out fruit fly pests that damage crops such as oranges, peaches, apples and pears.

Genetically modified versions of the Mediterranean fruit fly were created earlier this year using controversial technology developed by the UK bioscience company Oxitec.

Millions of male GM flies have been created in the laboratory to include a gene which means that when they mate with wild females, any resulting female larvae die before reaching maturity.

The resulting fall in the number of female fruit flies should, in theory, lead to a collapse in the total population which will mean less damage is caused to food crops.

Oxitec has promoted the technology as an alternative to the use of harsh chemical pesticides to protect food crops and so boost yields and has held talks with UK government agencies to run trials in this country.

It describes the patterns and trends in the spread of crop pests, using global databases to investigate the factors that influence the number of countries reached by pests and the number of pests in each country.

Crop pests include fungi, bacteria, viruses, insects, nematodes, viroids and oomycetes.

'If crop pests continue to spread at current rates, many of the world's biggest crop producing nations will be inundated by the middle of the century, posing a grave threat to global food security,' said Dr Dan Bebber of the Biosciences department at the University of Exeter.

The study identifies the pests likely to be the most invasive in coming years, which includes three species of tropical root knot nematode whose larvae infect the roots of thousands of different plant species.

Another, Blumeria graminis, is a fungus that causes powdery mildew on wheat and other cereals.

And the Citrus tristeza virus (given its name meaning 'sadness' in Portuguese and Spanish by farmers in the 1930s) is also a threat, having reached 105 of 145 countries growing citrus by the year 2000.

Fungi lead the worldwide invasion of crops and are the most widely dispersed group, despite having the narrowest range of hosts.

The study looked at the current distributions of 1,901 crop pests and pathogens and historical observations of a further 424 species.

Significant use was made of historical CABI (Centre for Agriculture and Biosciences International) records, which document crop pests and diseases around the world from 1822 to the present day.

'By unlocking the potential to understand the distribution of crop pests and diseases, we're moving one step closer to protecting our ability to feed a growing global population,' said Dr Timothy Holmes, Head of Technical Solutions at CABI's Plantwise Knowledge Bank.

'The hope is to turn data into positive action.'

It supports the view of previous studies that climate change is likely to significantly affect pest pressure on agriculture, with the warming Earth having a clear influence on the distribution of crop pests.

The authors also describe the global game of cat-and-mouse as crops are introduced to pest free regions and briefly thrive, before their pursuers catch up with them.

Professor Sarah Gurr of Biosciences the University of Exeter added: 'New, virulent variants of pests are constantly evolving.

'Their emergence is favoured by increased pest population sizes and their rapid life-cycles, which force diversified selection and heralds the appearance of new aggressive genotypes.

'There is hope if robust plant protection strategies and biosecurity measures are implemented, particularly in the developing world where knowledge is scant.

'Whether such precautions can slow or stop this process remains to be seen.'


The global spread of crop pests and pathogens

By Daniel P. Bebber et al.



Current country- and state-level distributions of 1901 pests and pathogens and historical observation dates for 424 species were compared with potential distributions based upon distributions of host crops. The degree of ‘saturation’, i.e. the fraction of the potential distribution occupied, was related to pest type, host range, crop production, climate and socioeconomic variables using linear models.


More than one-tenth of all pests have reached more than half the countries that grow their hosts. If current trends continue, many important crop-producing countries will be fully saturated with pests by the middle of the century. While dispersal increases with host range overall, fungi have the narrowest host range but are the most widely dispersed group. The global dispersal of some pests has been rapid, but pest assemblages remain strongly regionalized and follow the distributions of their hosts. Pest assemblages are significantly correlated with socioeconomics, climate and latitude. Tropical staple crops, with restricted latitudinal ranges, tend to be more saturated with pests and pathogens than temperate staples with broad latitudinal ranges. We list the pests likely to be the most invasive in coming years.

Main conclusions

Despite ongoing dispersal of crop pests and pathogens, the degree of biotic homogenization of the globe remains moderate and regionally constrained, but is growing. Fungal pathogens lead the global invasion of agriculture, despite their more restricted host range. Climate change is likely to influence future distributions. Improved surveillance would reveal greater levels of invasion, particularly in developing countries.



Who would be giving the Communist clenched-fist salute these days?

Ecofascists, of course. The pic above is apparently from a new film full of Warmist hysteria. Some of the speakers sound a lot like old uncle Adolf too. One totalitarianism is as good as another to them, I guess.

We're running out of food!

So says the gullible Justin Gillis of the NYT -- completely ignoring all the facts.  Take for instance the current situation  in icy Canada:  “In Western Canada, we’re moving from a huge glut of wheat to still a pretty big carry-over, but by no means the kind of over-supply we had in the last year.  And in 2013: “Canola - Nationally, canola production increased 29.5% from 2012 to a record 18.0 million tonnes; “Wheat: Farmers reported record wheat production of 37.5 million tonnes, a 38.0% increase from 2012.".  The only crop not a record in 2013 was Barley and Oats."  Anybody who knows anything about international trade in farm products knows that the chronic problem is surpluses, not shortages

Runaway growth in the emission of greenhouse gases is swamping all political efforts to deal with the problem, raising the risk of “severe, pervasive and irreversible impacts” over the coming decades, according to a draft of a major new United Nations report.

Global warming is already cutting grain production by several percentage points, the report found, and that could grow much worse if emissions continue unchecked. Higher seas, devastating heat waves, torrential rain and other climate extremes are also being felt around the world as a result of human-produced emissions, the draft report said, and those problems are likely to intensify unless the gases are brought under control.

The world may already be nearing a temperature at which the loss of the vast ice sheet covering Greenland would become inevitable, the report said. The actual melting would then take centuries, but it would be unstoppable and could result in a sea level rise of 23 feet, with additional increases from other sources like melting Antarctic ice, potentially flooding the world’s major cities.

“Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reduction in snow and ice, and in global mean-sea-level rise; and it is extremely likely to have been the dominant cause of the observed warming since the mid-20th century,” the draft report said. “The risk of abrupt and irreversible change increases as the magnitude of the warming increases.”

The report was drafted by the Intergovernmental Panel on Climate Change, a body of scientists and other experts appointed by the United Nations that periodically reviews and summarizes climate research. It is not final and could change substantially before release.

The report, intended to summarize and restate a string of earlier reports about climate change released over the past year, is to be unveiled in early November, after an intensive editing session in Copenhagen. A late draft was sent to the world’s governments for review this week, and a copy of that version was obtained by The New York Times.

Using blunter, more forceful language than the reports that underpin it, the new draft highlights the urgency of the risks that are likely to be intensified by continued emissions of heat-trapping gases, primarily carbon dioxide released by the burning of fossil fuels like coal, oil and natural gas.

The report found that companies and governments had identified reserves of these fuels at least four times larger than could safely be burned if global warming is to be kept to a tolerable level.

From 1970 to 2000, global emissions of greenhouse gases grew at 1.3 percent a year. But from 2000 to 2010, that rate jumped to 2.2 percent a year, the report found, and the pace seems to be accelerating further in this decade.

A major part of the jump was caused by industrialization in China, which now accounts for half the world’s coal use. Those emissions are being incurred in large part to produce goods for consumption in the West.

The report noted that severe weather events, some of them linked to human-produced emissions, had disrupted the food supply in recent years, leading to several spikes in the prices of staple grains and destabilizing some governments in poorer countries.

Continued warming, the report found, is likely to “slow down economic growth, make poverty reduction more difficult, further erode food security, and prolong existing poverty traps and create new ones, the latter particularly in urban areas and emerging hot spots of hunger.”


Further comments on the above from Prof. Don Easterbrook, who has studied global climate change for five decades:

"Global warming is already cutting grain production by several percentage points", the report found, With no global warming in 15-18 years, how can 'global warming' cut grain production?

"and that could grow much worse if emissions continue unchecked."  The total increase in atmospheric CO2 during the only period when both CO2 and temp increased (1978-1998) was a whopping 0.004%.  That's going to cause a lot of warming?

Higher seas, In areas cited as 'drowning (Maldives, Kiribati, Bangladesh), the sea level in the Maldives has dropped a full meter since 1979; sea level in Kiribati is not rising faster than coral is growing upward; sea level change in Bangladesh is due largely to compaction of delta sediments, and on and on.  In the next 50 years (2064) global sea level rise will be only about 3 inches!

"devastating heat waves, torrential rain and other climate extremes" This is simply not true--hurricanes, tornadoes, droughts, etc are all declining, not increasing.

"The world may already be nearing a temperature at which the loss of the vast ice sheet covering Greenland would become inevitable, the report said. The actual melting would then take centuries, but it would be unstoppable and could result in a sea level rise of 23 feet, with additional increases from other sources like melting Antarctic ice, potentially flooding the world’s major cities."  Nonsense! Except for a few small blips, all of the past 10,000 years to 1500 years ago were 2.5 to 5.5 F warmer than present in Greenland and the ice sheet didn't disappear. As for the Antarctic, the average annual temp is -58 F so warming of 100 F would be required to melt the Antarctic ice sheet.

“Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reduction in snow and ice, and in global mean-sea-level rise; and it is extremely likely to have been the dominant cause of the observed warming since the mid-20th century,” Global snow and ice is on the increase, not decreasing, the rate of global sea level rise has decreased in recent years, modeling results have not even come close to predicting global temperatures in the past few decades and with no warming in 18 years, how can human influence be invoked?

"A continued rapid growth of emissions in coming decades could conceivably lead to a global warming exceeding 8 degrees Fahrenheit, the report found."  This is based on computer models that have proven to be totally worthless in predicting global temperature for even a few decades, so why should this number have any credibility?

What is really astonishing, is how the discredited IPCC can continue to put out such nonsense totally contrary to real evidence and still pretend to be scientists.


Study: Cutting Emissions Pays for Itself

This is just another model-driven fantasy.  There is NO WAY less CO2 in the air would be healthier.  We breathe CO2 out every minute of our day.  We are totally used to it.  And it would be a WARMER world, not a cooler one that is more healthy.  Cold weather (winter) is the time of our great dying.  Just ask any hospital administrator.

The only scintilla of sense in the article is that burning fossil fuel tends to give off particulate matter, which can be a health hazard in large quantities. But such health hazards mainly exist in third world countries.  Where power is produced in modern power stations, particulate matter is filtered out.  No doubt some very fine particles escape but, despite many attempts, there has been no study that shows such pollution to have health effects.  I reviewed such studies over and over on my FOOD & HEALTH SKEPTIC blog and found them all to be flawed and therefore inconclusive.  The article below is just one big train of dubious assumptions

Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution.

But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions? MIT researchers looked at three policies achieving the same reductions in the United States, and found that the savings on health care spending and other costs related to illness can be big—in some cases, more than 10 times the cost of policy implementation.

“Carbon-reduction policies significantly improve air quality,” says Noelle Selin, an assistant professor of engineering systems and atmospheric chemistry at MIT, and co-author of a study published today in Nature Climate Change. “In fact, policies aimed at cutting carbon emissions improve air quality by a similar amount as policies specifically targeting air pollution.”

Selin and colleagues compared the health benefits to the economic costs of three climate policies: a clean-energy standard, a transportation policy, and a cap-and-trade program. The three were designed to resemble proposed U.S. climate policies, with the clean-energy standard requiring emissions reductions from power plants similar to those proposed in the Environmental Protection Agency’s Clean Power Plan.

Health savings constant across policies

The researchers found that savings from avoided health problems could recoup 26 percent of the cost to implement a transportation policy, but up to 10.5 times the cost of implementing a cap-and-trade program. The difference depended largely on the costs of the policies, as the savings—in the form of avoided medical care and saved sick days—remained roughly constant: Policies aimed at specific sources of air pollution, such as power plants and vehicles, did not lead to substantially larger benefits than cheaper policies, such as a cap-and-trade approach.

Savings from health benefits dwarf the estimated $14 billion cost of a cap-and-trade program. At the other end of the spectrum, a transportation policy with rigid fuel-economy requirements is the most expensive policy, costing more than $1 trillion in 2006 dollars, with health benefits recouping only a quarter of those costs. The price tag of a clean energy standard fell between the costs of the two other policies, with associated health benefits just edging out costs, at $247 billion versus $208 billion.

“If cost-benefit analyses of climate policies don’t include the significant health benefits from healthier air, they dramatically underestimate the benefits of these policies,” says lead author Tammy Thompson, now at Colorado State University, who conducted the research as a postdoc in Selin’s group.

Most detailed assessment to date

The study is the most detailed assessment to date of the interwoven effects of climate policy on the economy, air pollution, and the cost of health problems related to air pollution. The MIT group paid especially close attention to how changes in emissions caused by policy translate into improvements in local and regional air quality, using comprehensive models of both the economy and the atmosphere.

In addition to carbon dioxide, burning fossil fuels releases a host of other chemicals into the atmosphere. Some of these substances interact to form ground-level ozone, as well as fine particulate matter. The researchers modeled where and when these chemical reactions occurred, and where the resulting pollutants ended up—in cities where many people would come into contact with them, or in less populated areas.

The researchers projected the health effects of ground-level ozone and fine particulate matter, two of the biggest health offenders related to fossil-fuel emissions. Both pollutants can cause asthma attacks and heart and lung disease, and can lead to premature death.

In 2011, 231 counties in the U.S. exceeded the EPA’s regulatory standards for ozone, the main component of smog. Standards for fine particulate matter—airborne particles small enough to be inhaled deep into the lungs and even absorbed into the bloodstream—were exceeded in 118 counties.

While cutting carbon dioxide from current levels in the U.S. will result in savings from better air quality, pollution-related benefits decline as carbon policies become more stringent. Selin cautions that after a certain point, most of the health benefits have already been reaped, and additional emissions reductions won’t translate into greater improvements.

“While air-pollution benefits can help motivate carbon policies today, these carbon policies are just the first step,” Selin says. “To manage climate change, we’ll have to make carbon cuts that go beyond the initial reductions that lead to the largest air-pollution benefits.”

The study shows that climate policies can also have significant local benefits not related to their impact on climate, says Gregory Nemet, a professor of public affairs and environmental studies at the University of Wisconsin at Madison who was not involved in the study.

“A particularly notable aspect of this study is that even though several recent studies have shown large co-benefits, this study finds large co-benefits in the U.S., where air quality is assumed to be high relative to other countries,” Nemet says. “Now that states are on the hook to come up with plans to meet federal emissions targets by 2016, you can bet they will take a close look at these results.



The Wunsch/Lloyd controversy and the ocean deeps

A month ago, "The Australian" published a summary by Graham Lloyd of a forthcoming paper by Carl Wunsch which found cooling, not the warming predicted by Warmists, in the ocean deeps.  This embarrassed Wunsch, who wrote a "corrective" letter which was published in "The Australian" shortly thereafter.  A warmist blog then piled onto the action in an attempt to rubbish the Lloyd article but added little to what Wunsch had said.  I have now had time to read all three documents and can see nothing wrong with the Lloyd article.  I reproduce below both the original article and Wunsch's reply so that people can judge for themselves.

The only substantial point Wunsch makes in his short reply was that he believes that the ocean is warming overall, though he does not say by how much.  That may have saved Wunsch's reputation among Warmists but it was not the point of the Lloyd article.  The point is that all the warming allegedly hidden in the ocean deeps was not found. There was in fact on average a tiny degree of cooling.  Even in his reply Wunsch admits that.  So the Lloyd article is indeed fatal to the last-ditch defence of their theory currently being mounted by Warmists

Perhaps the most interesting part of the Lloyd article, however, was a comment obtained from a Prof. Hogg at the very end of the article.  He pointed out that change comes very slowly to the ocean deeps:  “So if cooling has occurred over large parts of the abyssal ocean, it is unrelated to global warming of the atmosphere over the last century.”  Equally, then, if warming has occurred over large parts of the abyssal ocean, it is unrelated to global warming of the atmosphere over the last century.  The implication of that would seem clearly to be that there is NO CHANCE of current warming being found in the ocean deeps.

Puzzle of deep ocean cooling

THE deep oceans have been cooling for the past two decades and it is not possible to say whether changes in ocean heat adequately explain the “pause” in global warming, two of the world’s leading ocean scientists have said.

Warmer oceans have been a key explanation for the “missing” heat. Global average surface temperatures have not increased dramatically for more than a decade despite steadily rising carbon dioxide levels in the ­atmosphere.

A paper by Carl Wunsch from Harvard University and Patrick Heimbach from MIT, accepted for publication with the Journal of Physical Oceanography, says more work is needed.

“Direct determination of changes in ocean heat content over the past 20 years are not in conflict with estimates of the radiative forcing, but the uncertainties remain too large to rationalise, e.g. the apparent ‘pause’ in warming,” Professor Wunsch and Dr Heimbach say.

They conclude that much less heat is being added to the oceans than has been claimed in previous studies.

Professor Wunsch and Dr Heimbach say trends showed a warming in the upper ocean and a net cooling below 2000m. Below 3600m, the cooling is about 0.01C over 19 years.

“As with many climate-­related records, the unanswerable question here is whether these changes are truly secular, and/or a response to anthropogenic forcing, or whether they are fragments of a general red noise behaviour,’’ the paper says.

Some climate scientists claim the deep oceans are not significant because of the long time­frames over which temperature changes occur.

Professor Wunsch and Dr Heimbach say shifts in deep ocean properties “may indeed be so slight that their neglect in discussions of heat uptake and sea level change is justified”.

“The history of exploration suggests, however, that blank places on the map have either been assumed to be without any interesting features and dropped from further discussion, or at the other extreme filled with ‘dragons’ invoked to explain strange reports,” they say.

The paper says that, given the combination of the high stakes for society in the accurate ­estimation of global heating rates and sea level rise, and the fundamental science questions of understanding of oceanic variability, direct confirmation or refutation of the existing hypothesis was essential.

Andy Hogg from ANU said while there was uncertainty about temperatures in the deep ocean, shallower regions were well understood, and the findings of the Wunsch paper were “consistent” with warming oceans. He said cooling of the deep ocean was not necessarily significant. “Most parts of the abyssal ocean take a very long time (centuries to millennia) to come into equilibrium with surface forcing,” he said. “So if cooling has occurred over large parts of the abyssal ocean, it is unrelated to global warming of the atmosphere over the last century.”

He said there were key parts of the abyss, which had a closer connection with the surface. “The paper indicates that these regions have indeed been consistent with the expected heat uptake of the ocean in a warmer world,” Dr Hogg said.

A recent paper by Matthew England, executive director of the climate change research centre at the University of NSW, said the global surface temperature “hiatus” could be explained by increased winds in the Pacific Ocean. The paper claims the strong trade winds, which pushed heat deeper into the ocean, explained why climate models had not matched physical observations on global temperatures, a key area of dispute between climate scientists and sceptics.

Understanding the ocean

THE article by Graham Lloyd will likely leave a mis-impression with many of your readers concerning the substance of our paper that will appear in the Journal of Physical Oceanography (“Puzzle of deep ocean cooling”, 25/7).

We never assert that global warming and warming of the oceans are not occurring — we do find an ocean warming, particularly in the upper regions.

Contrary to the implications of Lloyd’s article, parts of the deep ocean are warming, parts are cooling, and although the global abyssal average is negative, the value is tiny in a global warming context.

Those parts of the abyss that are warming are most directly linked to the surface (as pointed out by Andy Hogg from the ANU).

Scientifically, we need to better understand what is going on everywhere, and that is an issue oceanographers must address over the next few years — a challenging observational problem that our paper is intended to raise.

Large conclusions drawn from just 3 years of Cryosat-2 data

Even using ICEsat data extends the series to only 5 years  -- far too little to support claims of a trend.  A larger series could reveal very different earlier changes. The report below is objective enough.  It is only the spin Warmists are putting on it that is fanciful.  Note that the report below admits that the Antarctic sheet is both thickening and thinning (in different places)  -- so any trend is not even Antarctic-wide, let alone global

Elevation and elevation change of Greenland and Antarctica derived from CryoSat-2

By V. Helm, A. Humbert, and H. Miller


This study focuses on the present-day surface elevation of the Greenland and Antarctic ice sheets. Based on 3 years of CryoSat-2 data acquisition we derived new elevation models (DEMs) as well as elevation change maps and volume change estimates for both ice sheets. Here we present the new DEMs and their corresponding error maps. The accuracy of the derived DEMs for Greenland and Antarctica is similar to those of previous DEMs obtained by satellite-based laser and radar altimeters. Comparisons with ICESat data show that 80% of the CryoSat-2 DEMs have an uncertainty of less than 3 m ± 15 m. The surface elevation change rates between January 2011 and January 2014 are presented for both ice sheets. We compared our results to elevation change rates obtained from ICESat data covering the time period from 2003 to 2009. The comparison reveals that in West Antarctica the volume loss has increased by a factor of 3. It also shows an anomalous thickening in Dronning Maud Land, East Antarctica which represents a known large-scale accumulation event. This anomaly partly compensates for the observed increased volume loss of the Antarctic Peninsula and West Antarctica. For Greenland we find a volume loss increased by a factor of 2.5 compared to the ICESat period with large negative elevation changes concentrated at the west and southeast coasts. The combined volume change of Greenland and Antarctica for the observation period is estimated to be −503 ± 107 km3 yr−1. Greenland contributes nearly 75% to the total volume change with −375 ± 24 km3 yr−1.

Global warming pause 'may last for another decade', scientists suggest

Basic physics:  When something is hot, its molecules are farther apart than when it is cold. When water is hot, its molecules are further apart, so it takes up more room. That makes hot water lighter than cold water, because the cold water has more molecules in the same amount of room. And put a ping-pong ball into any container of water and watch it sink to the bottom (NOT!).  It's only in Warmist models that hot (less dense) water sinks.  And the Warmists not only say that warm water sinks to the bottom but they also say that the warm water stays down there for many years.  It's science fantasy, not science fact.  There's no science left in Warmism

The “pause” in global warming may last another decade before surface temperatures start rising again, according to scientists who say heat is being stored in the depths of the Atlantic and Southern Oceans.

Global average surface temperatures rose rapidly from the 1970s but have been relatively stable since the late 1990s, in a trend that has been seized upon by climate sceptics who question the science of man-made warming.

Climate change scientists have proposed more than a dozen theories to explain the "hiatus", which they say is a "distraction" from the widespread consensus on global warming.

A new study, published in the journal Science, suggests that a natural cycle of ocean currents has caused the phenomenon by drawing heat from shallow waters down almost a mile into the depths of the Atlantic and Southern Oceans.

The cycle naturally produces periods of roughly 30 years in which heat is stored near the surface of the Atlantic Ocean, leading to warmer temperatures, followed by roughly 30 years in which it is stored in the depths, causing cooler surface temperatures, it suggests.

Rising surface temperatures in the last three decades of the 20th century were roughly half caused by man-made global warming and half by the ocean currents keeping more heat near the surface, it finds.

When the ocean cycle reversed around the turn of the century, drawing heat down into the depths, this served to counteract the effects of man-made global warming.

"When the internal variability that is responsible for the current hiatus switches sign, as it inevitably will, another episode of accelerated global warming should ensue," the study concludes.

Prof Ka-Kit Tung of the University of Washington, one of the report's authors, said: "Historically the cool period lasted 20 to 35 years. The current period already lasted 15 years, so roughly there [are] 10 more years to go."

But he said that other impacts of climate change could upset the cycle, which is caused by variation in the salinity of the water as denser, saltier water sinks.

Prof Tung said the study's findings were a surprise because previous studies had suggested it was the Pacific Ocean that was "the culprit for hiding heat".

"The data are quite convincing and they show otherwise," he said.

Prof Piers Forster, professor of climate change at the University of Leeds, said the paper was "another a nail in the coffin of the idea that the hiatus is evidence that our projections of long term climate change need revising down".

"Variability in the ocean will not affect long-term climate trends but may mean we have a period of accelerated warming to look forward to," he said.

Prof Richard Allan, professor of climate science at the University of Reading, said: "Although it is human nature to seek a single cause for notable events, in reality the complexity of the climate system means that there is not one simple explanation for a decade of unusual climatic conditions."



Authoritarianism and the Leftist mental bubble

Nothing could be more obvious than the fact that Leftism is authoritarian.  Wanting to "change society" in some way is definitional of Leftism. That wish, in various forms, is what makes you a Leftist.  Conservatives want change too but generally in the direction of unwinding Leftist changes.  But, as Margaret Thatcher memorably said, there is no such thing as society.  There are only people.  So the Leftist wants to change what people do.   And that is the essence and goal of the authoritarian.  And once they gain untrammelled power, socialists such as Robespierre, Lenin, Stalin, Hitler, Pol Pot etc show how very authoritarian they in fact are.

But no Leftist seems to be able to see that.  They are in fact so heavily defended against reality that they believe it is conservatives who are the authoritarians.  I have on my bookshelf a book by Robert Altemeyer which is titled: "Enemies of freedom".  Any conservative would immediately identify the Left as the enemies of freedom but to Altemeyer the enemy is a type of conservative.  Like most Leftist psychologists, Altemeyer has obviously read nothing of what conservatives actually advocate.  Leftists need their cloak of self-righteousness so badly that they have to stay within a mental bubble formed by fellow Leftists -- a bubble into which uncomfortable thoughts must not intrude.

And that malarkey has been going on for a long time.  The ball really got rolling with the publication of "The authoritarian personality" under the lead authorship of Marxist theoretician Theodor Adorno (born Theodor Wiesengrund) in 1950.  And Altemeyer's writings are just an update on that.  Adorno identified conservatives as the authoritarians.

In my days doing psychological research, I had over 100 papers published pointing to the holes in the Adorno theory but the  papers had nil effect.  My findings could not be allowed to penetrate the little mental bubble that enabled Leftists to tar conservatives with what were in fact the traits of Leftists.

Occasionally, however, some courageous person pokes his head above the parapet and endeavours to question the demonization of conservatives.  I have commented previously on the work of Yancey, who points out that the flood of hate directed at Christians by Leftists makes claims of "hate" among conservatives look ludicrous.  Just to disagree with Leftists allegedly makes you a "hater".  To see what real hate looks like you have to see what Leftists say.

And I have just become aware of the work of Jarret T. Crawford, who is at least even-handed in finding fault on both the Left and the Right.  It is rather a wonder that he gets away with it, but, like Yancey, he appears to have some African ancestry.  So he is at that rate a member of a protected class and can say what he likes.  For anybody with social science interests a list of some of his writings is here.

Another reason for the acceptance of his work is that he operates within conventional Leftist parameters -- accepting Leftist measuring instruments such as the RWA and SDO scales at face value.  That is rather a pity as both instruments are abortions.  Although allegedly a measure of "Right-wing authoritarianism", the RWA scale offers no useful prediction of vote at election time!  Not very right-wing, is it?  In psychometric terms the scale lacks predictive validity.  And the SDO scale is an even bigger joke -- as I pointed out some years ago.

I look forward to Crawford discovering psychometrics.  With better measuring instruments there is no telling what he might find.  My paper on  SDO does offer some alternatives.


More Warmist deception

The notorious Mark Serreze fails to mention below that there was open water at the North pole on several occasions throughout the 20th. century.  As NOAA says:  "Recently there have been newspaper articles describing the existence of open water at the North Pole. This situation is infrequent but has been known to occur as the ice is shifted around by winds. In itself, this observation is not meaningful."

And Serreze is simply lying about the Northwest passage.  It too has been navigated on many occasions in the past. It was first navigated by Roald Amundsen in 1903–1906.

 The North Pole may be briefly ice-free by September as global warming melts away Arctic sea ice, according to scientists from the National Snow and Ice Data Center in Boulder, Colorado.

"We kind of have an informal betting pool going around in our center and that betting pool is 'does the North Pole melt out this summer?' and it may well," said the center's senior research scientist, Mark Serreze.

It's a 50-50 bet that the thin Arctic sea ice, which was frozen in autumn, will completely melt away at the geographic North Pole, Serreze said.

The ice retreated to a record level in September when the Northwest Passage, the sea route through the Arctic Ocean, opened briefly for the first time in recorded history.

"What we've seen through the past few decades is the Arctic sea ice cover is becoming thinner and thinner as the system warms up," Serreze said.

Specific weather patterns will determine whether the North Pole's ice cover melts completely this summer, he said.

"Last year, we had sort of a perfect weather pattern to get rid of ice to open up that Northwest Passage," Serreze said. "This year, a different pattern can set up. so maybe we'll preserve some ice there. We're in a wait-and-see mode right now. We'll see what happens."

The brief lack of ice at the top of the globe will not bring any immediate consequences, he said.

"From the viewpoint of the science, the North Pole is just another point in the globe, but it does have this symbolic meaning," Serreze said. "There's supposed to be ice at the North Pole. The fact that we may not have any by the end of this summer could be quite a symbolic change."

Serreze said it's "just another indicator of the disappearing Arctic sea ice cover" but that it is happening so soon is "just astounding to me."

"Five years ago, to think that we'd even be talking about the possibility of the North Pole melting out in the summer, I would have never thought it," he said.

The melting, however, has been long seen as inevitable, he said.

"If you talked to me or other scientists just a few years ago, we were saying that we might lose all or most of the summer sea ice cover by anywhere from 2050 to 2100," Serreze said. "Then, recently, we kind of revised those estimates, maybe as early as 2030. Now, there's people out there saying it might be even before that. So, things are happening pretty quick up there."

Serreze said those who suggest that the Arctic meltdown is just part of a historic cycle are wrong.

"It's not cyclical at this point. I think we understand the physics behind this pretty well," he said. "We've known for at least 30 years, from our earliest climate models, that it's the Arctic where we'd see the first signs of global warming.

"It's a situation where we hate to say we told you so, but we told you so," he said.



University rankings out again

There are now rather a lot of these rankings, all using slightly different methodology, but the latest out is the well established Shanghai Jiao Tong ranking.

No great surprises in the top ten, though Oxford would be sniffy about being ranked lower than Cambridge.

As usual, Australian universities had a good showing, with Melbourne in the top 50 and ANU at 74,  Queensland at 85 and UWA at 88.  Queensland is my Alma Mater so nobody can cast nasturtiums on my background.  My son is back there too.

And one of Brisbane's newer universities (Griffith) put out a press release expressing pleasure at being ranked 400th!  That is not as silly as it sounds when you realize that is 400th out of 10,000 -- and rankings lower than 500 are not released.
And Israelis will be pleased that their small community produced two in the top 100 -- Hebrew and Technion. And that is despite the "brain drain" of Ashkenazim to American universities.  No Palestinian universities made it into the top 500, however.  I believe there is one. Maybe the Palis could send some suicide bombers over to Shanghai to show those Chinamen at Jiao Tong University a thing or two!

The first non-American university on the list was -- at 19 -- The Swiss Federal Institute of Technology Zurich, which I know nothing about.  I have certainly never seen a paper from them.  Did Einstein go there or something?

The ranking of Leiden university in the Netherlands may indicate that there is such a thing as Dutch modesty.  They ranked at 77 when in the ranking system that they themselves run they come in only at 100!

Brits will be peeved that LSE made it only into the 100-150 bracket.  I gather that they have a lot of Muslims there.  And I was slightly peeved to see Sydney also in that bracket  I have a large document issued to me by that university. At least it did better than Macquarie, which was at 201-300.  I also have a large document issued to me  by Macquarie.

Three New Zealand universities made it into the top 500, which isn't bad for a country of only 4 million souls, though the ranking of Victoria University Wellington (401-500)  will disappoint many. I very nearly took a job there once.

The methodology used by the Shanghai rankings is entirely academic and research oriented. The project is supported by the Chinese government so it is a pretty good look "from outside".  The huge preponderance of American universities in the rankings would have to be taken with a large grain of salt if it were Americans who were doing the rankings but since the work was in fact done by Chinese academics, it is not subject to that suspicion.


Two very different Warmists meet  -- and we see which is rational

Kevin Trenberth is allegedly a scientist but is certainly a global warming evangelist.  His second most famous quote is:  "The planet is warming", but "the warmth just isn’t being manifested at the surface".   Pielke Jr. says he believes in global warming but doesn't think anyone can do anything about it.  Pielke enrages other Warmists.  He reports via Twitter:

Roger Pielke Jr. @RogerPielkeJr

I debated Trenberth last week. From Kevin there was yelling, spittle & an apology. I stuck to IPCC AR5 which he called totally wrong. Weird.

IPCC AR5 is the latest U.N. climate report



Steve Sailer demolishes in short order the ideas of Malcolm Gladwell here.  Gladwell is a real intellectual lightweight.  His grades were not good enough for graduate school. There is nothing creditable about propounding striking ideas if those ideas are wrong or unproven. I think it is mainly the bush of African hair on his head that gets Gladwell uncritical acceptance. He runs fast, though.  I have mentioned previously the demolition of Gladwell's most recent book by Christopher Chabris, a psychology professor and psychometrician.

It is generally conceded, however, that Gladwell is a good entertainer.  It is perhaps in that light that we can understand the success that his academically unsatisfactory writings have brought him.


"Flores man" just had Down's syndrome

This vindicates what was my conclusion from the start:  That Flores man was not a new species. The small stature of the person seemed to indicate a new species to many but that was not in fact unusual in Australia once. And Australia and Indonesia are of course neighbouring countries. 

All mention of Australia's first inhabitants --a pygmy race -- is normally suppressed these days but there are old photographs to prove their existence. And one (height 3'7") was alive until recently. They have now interbred with the Aborigines but some are still very short.  Their last holdout was in Kuranda and one day in 2004 a very short man walked right past me in Kuranda's main street. 

So I think an explanation of the bones as those of a very short person with Downs syndrome covers the evidence very well

The oldest case of Down's syndrome? 15,000-year-old 'Flores man' bones are not evidence of a new human species, study reveals

In October 2004 skeletal remains found on the island of Flores in Indonesia hinted at a previously unknown species of human that existed 15,000 years ago.

Called Homo floresiensis, the species was dubbed a ‘hobbit’ as it was smaller than any other known species of human.

But reanalysis has revealed that it may not be a new species at all, but rather a human that has features consistent with someone with Down's syndrome.

The latest findings, reported in the Proceedings of the National Academy of Sciences, was conducted by an international team of researchers.

They suggest that the single specimen on which the new designation depends, known as LB1 after the cave it was discovered in - Liang Bua - does not represent a new species.

Indeed, aside from LB1, no substantial new bone discoveries have been made in the cave since this finding.

‘The skeletal sample from Liang Bua cave contains fragmentary remains of several individuals,’ said Dr Robert Eckhardt, professor of developmental genetics and evolution at Penn State University.

‘LB1 has the only skull and thigh bones in the entire sample.’

The first indicator that the finding could be explained by Down's syndrome was craniofacial asymmetry, a left-right mismatch of the skull that is characteristic of the disorder.

The 15,000-year-old skeleton, officially known as Homo floresiensis, got its nickname from its squat stature.

The 3-foot (1-metre) tall, 30-year-old female was based on remains that were uncovered in the Liang Bua cave on the remote Indonesian island of Flores in 2003.

Since the discovery, scientists debated whether the specimen actually represents an extinct species in the human family tree, perhaps a diminutive offshoot of Homo erectus, a 1.8-million-year-old hominid and the first to have body proportions comparable to those of modern Homo sapiens.

The researchers noted this asymmetry in LB1 as early as 2006, but it had not been reported by the excavating team and was later dismissed as a result of the skull's being long buried, he said.

Initial descriptions of Homo floresiensis focused on LB1's unusual anatomical characteristics: a cranial volume reported as only 380 milliliters (23.2 cubic inches), suggesting a brain less than one third the size of an average modern human.

The skeleton also had short thigh bones, which were used to reconstruct a creature standing only 3.5 feet (1.06 metres) tall.

Although LB1 lived only 15,000 years ago, comparisons were made to earlier hominins, including Homo erectus and Australopithecus.

Other traits were characterised as unique and therefore indicative of a new species.

But a thorough re-examination of the available evidence in the context of clinical studies, the researchers said, suggests a different explanation.

In the first place, they write, the original figures for cranial volume and stature are underestimates, ‘markedly lower than any later attempts to confirm them.’

The researchers have consistently found a cranial volume of about 430 milliliters (26.2 cubic inches).

'The difference is significant, and the revised figure falls in the range predicted for a modern human with Down's syndrome *from the same geographic region*, Dr Eckhardt said.

LB1 is shown in three different views to illustrate facial asymmetry. A is the actual specimen, B is the right side doubled at the midline and mirrored, and C is the left side doubled and mirrored. Differences in left and right side facial architectures are apparent, and illustrate growth abnormalities of LB1

Differences in left and right side facial architectures are apparent, and illustrate growth abnormalities of LB1

The original estimate of 3.5 feet (1.06 metres) for the creature's height was based on extrapolation combining the short thigh bone with a formula derived from an African pygmy population.

But humans with Down's syndrome also have diagnostically short thigh bones, Dr Eckhardt said.

Though these and other features are unusual, he acknowledged, 'unusual does not equal unique.

'The originally reported traits are not so rare as to have required the invention of a new hominin species.'

Instead, the researchers build the case for an alternative diagnosis: that of Down's syndrome, one of the most commonly occurring developmental disorders in modern humans.

'When we first saw these bones, several of us immediately spotted a developmental disturbance,' said Eckhardt, 'but we did not assign a specific diagnosis because the bones were so fragmentary.  'Over the years, several lines of evidence have converged on Down's syndrome.'

A previously unpublished measurement of LB1's occipital-frontal circumference - the circumference of the skull taken roughly above the tops of the ears - allowed the researchers to compare LB1 to clinical data routinely collected on patients with developmental disorders.

Here too, the brain size they estimate is within the range expected for an Australomelanesian human with Down's syndrome.

LB1's short thigh bones not only match the height reduction seen in Down's syndrome, Dr Eckhardt said, but when corrected statistically for normal growth, they would yield a stature of about 1.26 meters, or just over four feet, a figure matched by some humans now living on Flores and in surrounding regions. [Vietnamese can be very short too]

These and other Down-like characteristics, the researchers state, are present only in LB1, and not in the other Liang Bua skeletal remains, further evidence of LB1's abnormality.

'This work is not presented in the form of a fanciful story, but to test a hypothesis: Are the skeletons from Liang Bua cave sufficiently unusual to require invention of a new human species?' Dr Eckhardt said.

'Our reanalysis shows that they are not. The less strained explanation is a developmental disorder.

'Here the signs point rather clearly to Down's syndrome, which occurs in more than one per thousand human births around the world.'



The latest survey cookery (Verheggen, Cook, et al.) by Warmists is worthless

A new survey of climate scientists has been published. The author team is headed by Bart Verheggen and includes John Cook. Here's the abstract:

    "Results are presented from a survey held among 1868 scientists studying various aspects of climate change, including physical climate, climate impacts, and mitigation. The survey was unique in its size, broadness and level of detail. Consistent with other research, we found that, as the level of expertise in climate science grew, so too did the level of agreement on anthropogenic causation. 90% of respondents with more than 10 climate-related peer-reviewed publications (about half of all respondents), explicitly agreed with anthropogenic greenhouse gases (GHGs) being the dominant driver of recent global warming. The respondents’ quantitative estimate of the GHG contribution appeared to strongly depend on their judgment or knowledge of the cooling effect of aerosols. The phrasing of the IPCC attribution statement in its fourth assessment report (AR4) providing a lower limit for the isolated GHG contribution may have led to an underestimation of the GHG influence on recent warming. The phrasing was improved in AR5. We also report on the respondents’ views on other factors contributing to global warming; of these Land Use and Land Cover Change (LULCC) was considered the most important. Respondents who characterized human influence on climate as insignificant, reported having had the most frequent media coverage regarding their views on climate change."

Having Cook on the author team is obviously going to lead many people to write the paper off without even taking a look at it. When you are proven to have set out to write a paper to meet a predetermined conclusion, that is the way people will treat your work.


Further comments by JR:

Note the following statement from the full paper:

"Participation in our survey was sought from scientists having authored or coauthored peer-reviewed articles or assessment reports related to climate change"

Also note:

"1868 questionaires were returned, although not all of these were fully completed. This amounts to a response rate of 29%"

So these were NOT atmospheric scientists.  They were anybody who had mentioned global warming in some paper or other.  It is hence NOT an expert sample.

Furthermore, the response rate was so low that it is not a representative sample either.  It is entirely possible that people  who wanted to keep their heads down in a very controversial area were the core of the non-respondents -- and a major reason for wanting to keep  heads down would be the risks of acknowledging skepticism.  The way Warmists have attacked and penalized skepticism has made it impossible to get open responses in the matter and hence vitiates any survey of the field.  The conclusions of the study are therefore worthless.


When obscenity trumps the facts

Obscenity is a strange way to make a scientific point.  I have never seen it before.  But I think I know why the guy below used it.  He is desperate.  He must be aware of the latest findings in his own field and the latest finding is that current changes in the Arctic, particularly in thermokarsts, have a net COOLING effect. See "A shift of thermokarst lakes from carbon sources to sinks during the Holocene epoch".  That study concerns CO2 but the Warmist below makes no attempt to offset that finding against the methane observations that are giving him orgasms.  That the methane emissions ARE being offset in some way would seem to follow from the fact that there has been no global warming for 18 years.  And note that in the original methane study,  most of the "vast plumes" did not reach the surface so could not therefore affect the atmosphere

The planet is 'f**cked' after scientists found huge plumes of deadly methane escaping from the seafloor.  This is according to Dr Jason Box who claims that methane will be the main driver of climate change if it escapes into the atmosphere.

He said: 'If even a small fraction of Arctic sea floor carbon is released to the atmosphere, we're f'd'

The scientist, based at the Geological Survey of Denmark and Greenland, tweeted the provocative statement after a Swedish study found methane leaking beneath the Arctic.

Some of this methane – which is over 20 times more potent than CO2 at trapping heat - is now making it to the ocean's surface.

The leaking gas from the seafloor may have its origins in collapsing clusters of methane trapped in frozen water due to high pressure and low temperature.

Scientists at Stockholm University called the discovery 'somewhat of a surprise,' which, according to Dr Box, is an understatement.

Methane is the second-largest greenhouse gas contributor to climate change.  The gas is 23 times more potent than carbon dioxide in trapping heat and is currently being targeted by government in an attempt to mitigate global warming.

Methane pollution has declined by 11 per cent since 1990 even as the governments has pushed for greater use of natural gas.

But the longer view on methane pollution show that it will rise. The Obama administration points to studies that show that methane pollution is projected to increase to a level equivalent to over 620 million tonnes of carbon dioxide pollution in 2030, if no action is taken.

The conventional thought is that the bubbles would be dissolved before they reached the surface and that microorganisms would consume that methane.

But Dr Box said if the plumes are making it to the surface, there's a new source of heat-trapping gases that the planet needs to worry about.

This, he claims, is particularly disturbing because the Arctic is warming faster than nearly anywhere else on Earth.

His comments follow research in May which found that freshwater sources may be an unrealised source of methane.

Unlike carbon dioxide, which is highly soluble in water, methane exists in two forms in these freshwater sources: as a dissolved gas and encapsulated in bubbles that rise from sediments.

And this methane can lead to ozone production and levels of the gas in the atmosphere are 150 per cent higher than they were before the industrial revolution in U.S.

It is already known that in the melting regions of the Arctic where lakes, known as thermokarsts, which are lakes that break down plant material into methane.

This methane can then escape out of the lake, and once lit, could set ice on fire.

'I may escape a lot of this,' Dr Box told Motherboard, 'but my daughter might not. She's three years old.'



Australia in the grip of a ‘new stolen generation’?

The story below is totally biased.  It makes no mention of the high and chronic rate of alcohol abuse in Aboriginal families or the harsh way  Aboriginal men treat their women and children. I  have seen both with my own eyes.  Because of the "stolen generation" myth (triggered by child welfare authorities taking children away from severely dysfunctional Aboriginal homes) all State child welfare departments became very wary of removing Aboriginal children from their homes.  The result was a lot of dead and injured children.  It now seems that they have mostly returned to their  statutory responsibilities towards the children and are rescuing them once again

THE rate of indigenous children being taken from their families has become so rife, more are being removed today than at any other time in Australia’s sordid colonial history.

Figures reveal the number of indigenous children being forcibly taken from their homes has risen almost 400 per cent in 15 years, prompting Aboriginal Elders to condemn what they are labelling a ‘new Stolen Generation’.

Aboriginal and Torres Straight Islander children represent 4.6 per cent of the Australian population, and a whopping one third are in ‘out of home care’.

According to the Federal Government’s 1997 Bringing Them Home report, the number of indigenous children removed from their families at the time was 2785.

Fast forward fifteen years to 2012, where a report by the Federal Government’s Australian Institute of Health and Welfare recorded the instance of removal had risen almost 400 per cent to 13,299.

“More than 14,000 Aboriginal children are in what they call ‘out of home care’ in any given night in Australia,” said Paddy Gibson, a senior researcher at the University of Technology, Sydney.

“That is a far greater number of children removed in any year over the Stolen Generations period.”

According to Mr Gibson, Australia has essentially returned to an “assimilation policy” where mass removal of Aboriginal children is being used as a strategy to “deal with questions of Aboriginal disadvantage, just as it was in the Stolen Generations era”.

But the Federal Government has washed its hands of the problem, with the Minister for indigenous Affairs, Senator Nigel Scullion, telling news.com.au “Child protection is the responsibility of the states and territories. At all times and in all circumstances, the best interest of the child is paramount.

“However I do encourage states and territories to work harder to find solutions, where possible, within the wider Aboriginal and Torres Strait Islander family. Experience has shown that where issues can be resolved, the extended family is at the centre of the solution.”

In NSW nearly 6300 indigenous children are wards of the state. That’s nearly 10 per cent of the state’s Aboriginal children. Meanwhile, only 1.6 per cent of white children have been removed.

According to the Northern Territory Children’s Commissioner’s annual report, indigenous children were 395 per cent more likely to be put into care than non-indigenous children.

In the year to June 30, 2013, 624 indigenous kids were removed in the Northern Territory, in comparison to 126 non-indigenous children.

Child protection services have denied having an unfair focus on indigenous communities, claiming it is beyond the Department’s control and that the health and welfare of the child was at the core of the department’s interests.

“The NSW Department of Family and Community Services (FACS) has a statutory responsibility to protect children, and will only remove a child or young person as a last resort when court order finds there are serious concerns for their safety or wellbeing, said a spokesman.

“The decision to remove a child from its family is not taken lightly by the Children’s Court, which treats all cases equally, no matter what the racial or social background.”

FACS pointed news.com.au to the 2014 Report on Government Services, which stated NSW had the highest percentage of indigenous children in out of home care placements with relatives or kin (63.6 per cent of indigenous children as compared to the national average of 51.5 per cent).

But Mr Jackson remained unconvinced.  “Yes we do have drunks, yes we do have druggies, some of them are mothers even, but in the wider family, not all of them are drunk or drug-affected,” he said.

“When you walk into an Aboriginal house, the first thing you see is a wall covered with photos. “Photos of family of those who have gone, those have just come and those who are in between and growing. Walk into the kitchen, the fridge is covered with children’s drawings. That is a normal home.

“That is pride in your family and children, and that is not being recognised.
