It’s a curious phenomenon that examples of climate ‘forcing’ always seem to occur just before big environmental summits, and that the forcing only ever goes in one direction. The UN Climate Change meeting at Cancun this week is no exception. The UK’s Met Office, among others, released a series of statements and in the Met Office’s case a brochure about climate change. Their conclusion is that things are probably worse than we thought, and in their opinion, is worse than the current science is telling us. I suppose in the face of uncertainties in the science, and contradictory data, touting authoritative opinion is seen as a way to influence important meetings (the Royal Society obviously thinks the same), although it must be said that when it comes to opinion the Met Office track record for accuracy is not shining.
Just four lines of information released in the Met Office’s brochure attracted most of the attention in the media. It seems that there is a case to be made that ocean temperatures need to be adjusted. Prior to about 2002 they need to be lowered, and post 2002 they need to be raised slightly.
Those four lines were;
Changes in the way sea-surface temperatures were measured
over the last decade have introduced a small artificial cooling
of up to 0.03 °C over the last decade. This is being corrected
in a new version of the Met Office dataset.
