NASA har väl en del pålitliga data, GISTEMP tex:

Realclimate brukar ange dem. Läsvärd sajt det, tycker jag. De hade en artikel om allt prat om att växthuseffekten minsann "stannat upp" och dylikt:

Citat:
John Tierney and Roger Pielke Jr. have recently discussed attempts to validate (or falsify) IPCC projections of global temperature change over the period 2000-2007. Others have attempted to show that last year's numbers imply that 'Global Warming has stopped' or that it is 'taking a break' (Uli Kulke, Die Welt)). However, as most of our readers will realise, these comparisons are flawed since they basically compare long term climate change to short term weather variability.
