Doha summit launches climate damage aid

THINGS took an interesting twist at the latest UN climate summit held in Doha, Qatar, over the past two weeks when nations began talks over paying for the damage caused by climate change. Delegates were split over a deal under which rich nations would pay when poor ones suffered the consequences of global warming. Developing countries demanded future compensation and developed ones - particularly the US - were unsurprisingly reluctant to agree.

The talks ended with yet another agreement to agree, but many are calling this small victory a significant step forward. The deal offers a distant promise of climate aid. But first, science will have to catch up with politics.

All countries will suffer as a result of climate change, even if humanity slashes its emissions and stops temperatures rising more than 2 �C above pre-industrial levels - the stated goal of the UN negotiations. At current rates, a 3 or 4 �C rise is likely this century.
