"AP July 8 2008:Targeting global warming, President Barack Obama and other leaders of the world's richest industrial countries pledged Wednesday to seek dramatic cuts in greenhouse gas emissions by 2050 to slow dangerous climate change. Setting a marker for success, they agreed for the first time that worldwide temperatures must not rise more than a few degrees.
However, their goals are nonbinding, and it's far from clear they will be met. The wealthy nations failed to persuade the leaders of big developing countries to promise to cut their own fast-spreading pollution, unable to overcome arguments that the well-established industrial giants aren't doing enough in the short term.
Obama and his counterparts from the other wealthy Group of Eight nations agreed that global temperatures should be kept from rising by more than 2 degrees Celsius, or 3.6 degrees Fahrenheit, in the fight against weather changes caused by humans.
The results left some Western leaders cheering. British Prime Minister Gordon Brown called the group's statement a "historic agreement." German Chancellor Angela Merkel said it was "a clear step forward."
