We’ve written about the leaked emails and other documents from the University of East Anglia’s Climatic Research Center here, here and here. Another intensely interesting email thread, which doesn’t seem to have gotten much notice, relates to the fact that the last decade, contrary to the alarmists’ predictions, has tended to get cooler, not warmer.
At the end of 2008, the scientists at East Anglia predicted that 2009 would be one of the warmest years on record:
On December 30, climate scientists from the UK Met Office and the University of East Anglia projected 2009 will be one of the top five warmest years on record. Average global temperatures for 2009 are predicted to be 0.4∞C above the 1961-1990 average of 14 ∫ C. A multiyear forecast using a Met Office climate model indicates a rapid return of global temperature to the long-term warming trend, with an increasing probability of record temperatures after 2009.
We know now that the alarmists’ prediction for 2009 didn’t come true. What’s interesting is that in January of this year, another climate alarmist named Mike MacCracken wrote to Phil Jones and another East Anglia climatologist, saying that their predicted warming may not occur:
Your prediction for 2009 is very interesting…and I would expect the analysis you have done is correct. But, I have one nagging question, and that is how much SO2/sulfate is being generated by the rising emissions from China and India…. While I understand there are efforts to get much better inventories of CO2 emissions from these nations, when I asked a US EPA representative if their efforts were going to also inventory SO2 emissions (amount and height of emission), I was told they were not. So, it seems, the scientific uncertainty generated by not having good data from the mid-20th century is going to be repeated in the early 21st century (satellites may help on optical depth, but it would really help to know what is being emitted).
That there is a large potential for a cooling influence is sort of evident in the IPCC figure about the present sulfate distribution–most is right over China, for example, suggesting that the emissions are near the surface–something also that is, so to speak, ‘clear’ from the very poor visibility and air quality in China and India. So, the quick, fast, cheap fix is to put the SO2 out through tall stacks. The cooling potential also seems quite large as the plume would go out over the ocean with its low albedo–and right where a lot of water vapor is evaporated, so maybe one pulls down the water vapor feedback a little and this amplifies the sulfate cooling influence.
