"To be precise, Prof Tol calculated that climate change would be beneficial up to 2.2˚C of warming from 2009 (when he wrote his paper). This means approximately 3˚C from pre-industrial levels, since about 0.8˚C of warming has happened in the last 150 years. The latest estimates of climate sensitivity suggest that such temperatures may not be reached till the end of the century — if at all. The Intergovernmental Panel on Climate Change, whose reports define the consensis, is sticking to older assumptions, however, which would mean net benefits till about 2080. Either way, it’s a long way off."
A man wrote a book on it and reviewed previous years of climate change.Stating that it changed raised the human and planetary welfare.Calculating 1.4 per cent of global economic output.The world growing a 3% each year.Which is fairly low.Considering how many people there are in the world.
