Too hot for comfort
My letter on global warming (2 January) contained a small but significant typo. The predicted rise in global temperature is from 2C to 6C, not 60C.
In the last glacial maximum, 20,000 years ago, much of the northern hemisphere was covered in ice sheets several kilometres thick, sea levels were 120m lower than today and you could walk from England to France, while global temperatures were only 5C cooler. This shows that seemingly small changes in global temperature can have significant impacts on the earth. Humans would never survive an increase of 60C.
