some global warming 'skeptics' argue that the earth's climate sensitivity is so low that a doubling of atmospheric co2 will result in a surface temperature change on the order of 1°c or less, and that therefore global warming is nothing to worry about.

climate sensitivity:7
the transient climate response (tcr) is the amount of temperature increase that might occur at the time when co2 doubles, having increased gradually by 1% each year.
