Half the Earth too hot by 2300

If anthropogenic global warming continues, over the next 300 years half of the Earth's surface may become too hot for human habitation, say scientists from Australia's University of New South Wales and Purdue University in the USA. Along with rising sea levels, biodiversity loss, and ocean acidification a major problem is the warming itself. If we are unable to stop the warming or adapt to the new conditions, global warming could be a real doomsday for human civilisation.
