The climate prophets finally get some modelling right -- but it says the opposite of what Warmists want!
Two Harvard scientists have just done the most careful modelling yet of what effects wind turbines have. They find that, for the next century, wind turbines will INCREASE warming rather than decrease it.
And here's the really exceptional bit: Their models agree with observations -- an unprecedented event in global warming literature. It means that you can make reasonably accurate predictions from their models -- unlike the chaff that comes from other modelling.
So what are Warmists saying about the study? You guessed it: Warmists of course hate the conclusions so say the modelling is no good. It would be interesting to see them do better.
Highlights and abstract below:
Climatic Impacts of Wind Power
Lee M.Miller & David W.Keith
Highlights
* Wind power reduces emissions while causing climatic impacts such as warmer temperatures
* Warming effect strongest at night when temperatures increase with height
* Nighttime warming effect observed at 28 operational US wind farms
* Wind's warming can exceed avoided warming from reduced emissions for a century
Summary
We find that generating today's US electricity demand (0.5 TW e) with wind power would warm Continental US surface temperatures by 0.24°C. Warming arises, in part, from turbines redistributing heat by mixing the boundary layer. Modeled diurnal and seasonal temperature differences are roughly consistent with recent observations of warming at wind farms, reflecting a coherent mechanistic understanding for how wind turbines alter climate. The warming effect is: small compared with projections of 21st century warming, approximately equivalent to the reduced warming achieved by decarbonizing global electricity generation, and large compared with the reduced warming achieved by decarbonizing US electricity with wind. For the same generation rate, the climatic impacts from solar photovoltaic systems are about ten times smaller than wind systems. Wind's overall environmental impacts are surely less than fossil energy. Yet, as the energy system is decarbonized, decisions between wind and solar should be informed by estimates of their climate impacts.

The difference between weather and climate is a measure of time. Today I read a successful prediction of the future climate and the forecast was made in 1965. To be clear, the following climate forecast is not about the weather.
ReplyDeleteIf I were the Devil, if I were the Prince of Darkness, I’d want to engulf the whole world in darkness and I would have a third of its real estate and four-fifths of its population, but I wouldn’t be happy until I had seized the ripest apple on the tree, thee.
So I would set about however necessary to take over the United States. I’d subvert the churches first. I’d begin with a campaign of whispers. With the wisdom of a serpent, I would whisper to you as I whispered to Eve: “Do as you please.”
To the young, I would whisper that the Bible is a myth. I would convince them that man created God instead of the other way around. I would confide that what is bad is good and what is good is “square.” And the old, I would teach to pray after me: “Our Father which art in Washington.”
And then I’d get organized. I’d educate authors in how to make lurid literature exciting so that anything else would appear dull and uninteresting. I’d make TV look worse than movies and then make movies look worse than TV in a vicious cycle that just gets worse and worse. I’d peddle narcotics to whomever [sic] I could. I’d sell alcohol to ladies and gentlemen of distinction. I’d tranquilize the rest with pills.
If I were the Devil, I’d soon have families at war with themselves, churches at war with themselves, and nations at war with themselves, until each in its turn was consumed. And with promises of higher ratings, I’d have mesmerizing media fanning the flames.
If I were the Devil, I would encourage schools to refine young intellects but neglect to discipline emotions; just let those run wild until, before you knew it, you’d have to have drug-sniffing dogs and metal detectors at every schoolhouse door. Within a decade, I’d have prisons overflowing. I’d have judges promoting pornography. Soon I could evict God from the courthouse, and then from the schoolhouse, and then from the houses of Congress. And in His own churches I would substitute psychology for religion and deify science. I would lure priests and pastors into misusing boys and girls and church money. If I were the Devil, I’d make the symbol of Easter an egg and the symbol of Christmas a bottle.
If I were the Devil, I would take from those who have and give to those who wanted, until I had killed the incentive of the ambitious. And what will you bet I couldn’t get whole states to promote gambling as the way to get rich. I would caution against extremes in hard work, in patriotism, in moral conduct. I would convince the young that marriage is old-fashioned, that swinging is more fun, that what you see on TV is the way to be and thus I could undress you in public and I could lure you into bed with diseases for which there is no cure.
In other words, if I were the devil I’d just keep right on doing on what he’s doing.
