It has always responded strongly to natural changes in Earth's energy budget - the balance between the absorbed incoming energy from the Sun and the outgoing long-wave (thermal) radiation from Earth. But the latest Intergovernmental Panel on Climate Change (IPCC) report ( ), which contains a 65-page chapter reviewing the main palaeoclimatic findings, shows that the first lesson from the past is that Earth's climate system is very sensitive. The often dramatic natural climate changes of the past are sometimes cited by those opposed to reducing greenhouse-gas emissions as evidence of why we need not worry about the ongoing warming. One of the best aspects of Six Degrees is that it pulls together data from past climate changes in Earth's history to get an idea of what a warmer climate might look like. ![]()
