Climate deal needs poorer-nation targets: Stern
A new international accord to fight global warming must extend greenhouse-gas limits to poorer nations that have fought caps for years, British economist Nicholas Stern said. All countries must pitch into reduce emissions by a combined 50%and help avoid dangerous temperature increases, Stern said in a report released in the UK. Currently a professor at the London School of Economics, Stern published a widely cited study of climate-change economics in 2006.
