A Warmer World

“All the promises in the world, which we’re not likely to realise anyway, will not give us a world with only a 2°C rise. All the evidence, in my opinion, suggests we’re on our way to a 3°C to 5°C world.

“Some people are suggesting that we try to geo-engineer our way out of the problem, intervening in the climate system to moderate warming.

“I’m very, very nervous about that. It shows a level of arrogance that we know how to manage our environment. It certainly needs a lot of research.”
Professor Sir Robert Watson
