Two different views from two sets of experts. The National Academy of Sciences:

Climate change is occurring, is caused largely by human activities, and poses significant risks for — and in many cases is already affecting — a broad range of human and natural systems."

The Royal Society has appointed a panel to rewrite the 350-year-old institution's official position on global warming. It will publish a new “guide to the science of climate change” this summer. The society has been accused by 43 of its Fellows of refusing to accept dissenting views on climate change and exaggerating the degree of certainty that man-made emissions are the main cause.

The society appears to have conceded that it needs to correct previous statements. It said: “Any public perception that science is somehow fully settled is wholly incorrect — there is always room for new observations, theories, measurements.” This contradicts a comment by the society's previous president, Lord May, who was once quoted as saying: “The debate on climate change is over.”

It would be nice to say that the debate on whether the debate is over is over,
