Nature: Oceans cool off in hottest years p 854. Temperature drop puzzles climate researchers I don't want to paste the article, but here are two paragraphs. Better observation systems are showing the oceans are more changeable than some people thought, says Gavin Schmidt, a climate modeller at the NASA Goddard Institute for Space Studies in New York City. A short-term cooling blip can’t say much about the climate system in general. But the latest study suggests, he says, that coupled ocean–climate models fail to adequately capture intermittent fluctuations in ocean temperature.(snip) Global cloud coverage has increased by 1–2% since 1999 according to data from the International Satellite Cloud Climatology Project, presumably because of global warming and increased evaporation. Other factors — such as cloud albedo (the extent to which cloud reflects solar radiation) or cloud-top temperature — might have changed in the same period, says William Rossow, a cloud expert at the Goddard Institute. “It is completely insufficient to look for a simple explanation of a shortterm temperature change,” he says, “as the climate system is much more complex.” This seems to fit in the general catagory of large short term variability that at times will swamp the very long term trend of warming. Had a hot summer? You cannot blame that on global warming yet. Wait for it.
