After crunching ice-age climate numbers, Oregon researchers and colleagues from Harvard, Princeton, Cornell and Barcelona came up with two encouraging conclusions about future global warming:
The planet appears less sensitive to carbon dioxide changes than expected, their study says, so extreme temperature increases in the near future appear highly unlikely.
And future warming may also be less than predicted by the Intergovernmental Panel on Climate Change in 2007, particularly at the upper end of the "likely" range.
