The world has warmed by approximately 0.7 degrees Celsius in the 200 years since fossil fuels began to be used on any significant scale[1]. The rate at which the planet is heating up could be accelerating and 2010 was the hottest year since the global record began, 131 years ago[2]. All ten of the warmest years on record have occurred since 1998.

Economic growth, population growth and climate change

Recent work cited in our report shows that the remaining global fossil fuel resources (mainly coal) would produce an enormous 9-13 trillion tonnes of greenhouse gas emissions. If all of it were burnt without capturing the carbon it would be enough to raise the average global temperature some 18 degree C, may be more. This 9-13 trillion tonnes is large compared with the 0.5 trillion tonnes …
