How sensitive is Earth’s climate? Sufficient to warm by at least several degrees in response to greenhouse gas pollution but perhaps not as sensitive as some scientists have feared, according to a new study.

Climate sensitivity is a measure of how much the global temperature will warm in response to greenhouse gas emissions, explained Gabriele Hegerl, a climate scientist at Duke University in Durham, North Carolina.

The measure specifically estimates how the climate might respond to a doubling of the amount of carbon dioxide in the atmosphere.
