Carbon pollution up to 2 million pounds a second - Wire - NewsObserver.com
WASHINGTON -- The amount of heat-trapping pollution the world spewed rose again last year by 3 percent. So scientists say it's now unlikely that global warming can be limited to a couple of degrees, which is an international goal.
Because emissions of the key greenhouse gas have been rising steadily and most carbon stays in the air for a century, it is not just unlikely but "rather optimistic" to think that the world can limit future temperature increases to 2 degrees Celsius (3.6 degrees Fahrenheit), said the study's lead author, Glen Peters at the Center for International Climate and Environmental Research in Oslo, Norway.
Andrew Weaver, a climate scientist at the University of Victoria in Canada who was not part of the study, said: "We are losing control of our ability to get a handle on the global warming problem."
