The climate sensitivity classically defined is the response of global mean temperature to a forcing once all the «fast feedbacks» have occurred (atmospheric temperatures, clouds, water vapour, winds, snow, sea ice etc.), but before any of the «slow» feedbacks have kicked in (ice sheets, vegetation, carbon cycle etc.).

Forests and other land vegetation currently remove up to 30 percent of human carbon dioxide emissions from the atmosphere during photosynthesis, but thanks to this latest study, experts now know that we have tropical forests to thank for a great deal of this work - absorbing a whopping 1.4 billion metric tons of CO2 out of a total total global absorption of 2.5 billion metric tons.

Policies which include improving carbon storage by increasing vegetation and biodiversity, along with reduction in carbon emissions, will help to balance global atmospheric carbon.

Indeed, the long lifetime of fossil fuel carbon in the climate system and persistence of the ocean warming ensure that «slow» feedbacks, such as ice sheet disintegration, changes of the global vegetation distribution, melting of permafrost, and possible release of methane from methane hydrates on continental shelves, would also have time to come into play.

There are two primary externalities that result from our emissions of carbon dioxide into the atmosphere — 1) an enhancement of the greenhouse effect, which results in an alteration of the energy flow in the earth's climate and a general tendency to warm the global average surface temperature, and 2) an enhancement of the rate of photosynthesis in plants and a general tendency to result in more efficient growth and an overall healthier condition of vegetation (including crops).

Thirdly, Earth system models have begun to incorporate more realistic and dynamic vegetation components, which quantify positive and negative biotic feedbacks by coupling a dynamic biosphere to atmospheric circulations with a focus on the global carbon cycle (Friedlingstein et al., 2003, 2006; Cox et al., 2004, 2006).
