Better science

The threat of global warming could be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70% this century, according to a new analysis by scientists at the USA's National Center for Atmospheric Research (NCAR). While global temperatures would rise, the most dangerous potential aspects of climate change, including massive losses of Arctic sea ice and permafrost and significant sea level rise, could be partially avoided.
The study, to be published next week in Geophysical Research Letters, indicates that we can no longer avoid significant warming during this century. Lead Author , Dr Warren Washington, says. "But if the world were to implement this level of emission cuts, we could stabilize the threat of climate change and avoid catastrophe."
