Professor Kevin Anderson, director of the Tyndall Centre for Climate Change in Britain :
‘‘For humanity it’s a matter of life or death … we will not make all human beings extinct, as a few people with the right sort of resources may put themselves in the right parts of the world and survive. But I think it’s extremely unlikely that we wouldn’t have mass death at 4 degrees.
Four degrees warming in Canada would make the place unlivable. Can you imagine winters at -26C instead of -30c?
