27. Climate change tipping points
28. Greenhouse gas forcing and the response of the climate system
(a) Linear but delayed response
(
Figure
28a
). In this case, the GHGs increase produces
a delayed but direct response in the climate system whose magnitude is in proportion
to the additional forcing. This can be equated to pushing a car along a flat road. At
first nothing happens as friction must be overcome before the car will start moving.
Once that has happened most of the energy put into pushing is used to move the car
forward.
