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:66
the 1990 ipcc first assessment report estimated that equilibrium climate sensitivity to a doubling of co 2 lay between 1.5 and 4.5 °c (2.7 and 8.1 °f), with a "best guess in the light of current knowledge" of 2.5 °c (4.5 °f).
