Rich nations alone can't halt global warming

Space Daily via AFP: Poor nations must make haste to curb greenhouse gas emissions as even an impossible zero-percent pollution target for the developed world by 2030 won't stop calamitous climate change, a report warned Tuesday.

Co-authored by former World Bank chief economist Nicholas Stern, the document said that while rich countries are responsible for the bulk of Earth-warming gas emissions since the industrial age, the world could not afford to play the blame-game.

All countries, rich and poor, were moving "recklessly slow" on reducing emissions, said the report issued on the sidelines of UN climate talks in Doha, Qatar.

"There is a deep inequity in that rich countries grew wealthy on high-carbon growth, and poor countries will be hit particularly hard by climate change," it said.

"Recognition of that inequity must play a strong part in building international collaboration, but must not be allowed to block progress: that would be the most inequitable of all outcomes"....
