The UK’s premier scientific organization, the Royal Society, has released a “new short guide to the science of climate change”.

Entitled Climate Change: a Summary of the Science, the 19-page document can be downloaded here.

The guide was produced in part because of pressure from 43 members of the society, who had complained that a 2007 report from the organization did not acknowledge fully areas of uncertainty in climate science.

As a result, the report has a more measured tone, but still asserts “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity.”
