WebA climate feedback is an internal climate process that amplifies or dampens the climate response to an initial forcing. An example is the increase in atmospheric water vapor that is triggered by an initial warming due to rising carbon dioxide (CO 2 ) concentrations, which then acts to amplify the warming through the greenhouse properties of ...
