As emissions increase, carbon 'sinks' get clogged
In the race to reduce greenhouse gases in the atmosphere, scientists have been looking to forests and oceans to absorb the pollution people generate.
World's oceans, forests becoming less able to absorb CO2
Relying on nature to compensate for human excesses sounds like a win-win situation -- except that these resources are under stress from the very emissions we are asking them to absorb, making them less able partners in the pact.
"What our ocean study and other recent land studies suggest is that we cannot count on these sinks operating in the future as they have in the past and keep on subsidizing our ever-growing appetite for fossil fuels," Khatiwala said.
