The team ran a suite of 400 computer simulations
incorporating both what is known about how the climate could react to a
greenhouse -
gas buildup and a wide range of variations in the global economy and other
human factors that might affect the outcome.
The red line
incorporates natural influences like changes in solar output and volcanic activity but virtually all of the long - term warming is attributable to
human - caused increases in
greenhouse gasses.
So we have a situation in which the latest science on two key issues: how much the earth will warm as a result of
human greenhouse gas emissions, and how well climate models perform in projecting the warming, is largely not
incorporated into the new IPCC report.
