Pace of climate change exceeds estimates:
“We are basically looking now at a future climate that’s beyond anything we’ve considered seriously in climate model simulations,” Christopher Field, founding director of the Carnegie Institution’s Department of Global Ecology at Stanford University, said.
… emissions from burning fossil fuels since 2000 have largely outpaced the estimates used in the U.N. panel’s 2007 reports.
Unexpectedly large amounts of carbon dioxide are being released into the atmosphere as the result of “feedback loops” that are speeding up natural processes.
