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.
