“Achieving a balance between sources and sinks of greenhouse gases in the second half of this century will require net carbon dioxide emissions to be reduced, in effect, to zero. It seems governments understand this, even if they couldn’t quite bring themselves to say so.”
Myles Allen, professor of geosystem science at Oxford University.
“Although different countries will move at different speeds, the transition to a low-carbon world is now inevitable. Governments, investors and businesses must ride this wave or be swept away by it.
Mohamed Adow, senior climate advisor, for Christian Aid, a development organization.
Elliot Diringer, executive vice president of the Center for Climate & Energy Solutions , a nonpartisan U.S. group that advocates for action to combat climate change
“To stabilize our climate, CO2 emissions have to peak well before 2030 and should be eliminated as soon as possible after 2050. Technologies such as bio-energy and carbon capture and storage as well as afforestation can play a role to compensate for residual emissions, but cutting CO2 is key.”
John Schellnhuber, director of the Potsdam Institute for Climate Impact Research
