No, not the stuff in the stolen emails — although the University of East Anglia and its Climatic Research Unit (CRU) have yet another statement out I’ll excerpt below. It notes “Over 95% of the CRU climate data set concerning land surface temperatures has been accessible to climate researchers, sceptics and the public for several years.”
No, the vital climate data that the Hadley Center and CRU are withholding from the public is the warming taking place in the Arctic (see “What exactly is polar amplification and why does it matter?“). And that missing data is why NASA’s Goddard Institute for Space Studies data are almost certainly superior to CRU’s data “developed in conjunction with Hadley Centre of the UK Met Office.”
Remember, “there are no permanent weather stations in the Arctic Ocean, the place on Earth that has been warming fastest,” as New Scientist explained (see here and here). “The UK’s Hadley Centre record simply excludes this area, whereas the NASA version assumes its surface temperature is the same as that of the nearest land-based stations.” Thus it is almost certainly the case that the planet has warmed up more this decade than NASA says, and especially more than the UK’s Hadley Center says.
RealClimate has an excellent post on this very subject “” “the ‘hole in the Arctic’ in the Hadley data, just where recent warming has been greatest” “” with this great figure (and caption):
Figure. The animated graph shows the temperature difference between the two 5-year periods 1999-2003 and 2004-2008. The largest warming has occurred over the Arctic in the past decade and is missing in the Hadley data.
Thus contrary to what the global warming disinformers say about the recent temperature record, it is almost certainly the case that the planet has warmed up more this decade than NASA says, and especially more than the UK’s Hadley Center says.
So that’s why the NASA temperature record should be seen as more accurate, which puts 2005 as the warmest year on record, with 2007 just edging out 1998 for second warmest. This is “the hottest decade the planet has experienced in many thousands of years,” as climatologist Ken Caldeira puts it. NASA has reported June to October were the hottest on record.* And next year may well be the warmest on record.
So, no, there hasn’t been any recent “global cooling” even for the surface temperature record. And when you look at where 90% of the human-caused warming was expected to go — the oceans — you find steady warming over the past several years:
