Sentences with phrase «estimated equilibrium effect»

Their result is close to the estimated equilibrium effect of doubling the concentration of CO2.

Not exact matches

The Hansen et al study (2004) on target atmospheric CO2 and climate sensitivity is quite clear on this topic: equilibrium responses would double the GCM - based estimates, with very little to be said about transient effects.

However, the GWPF report only references the «main results» of Aldrin et al. (2012), whose study actually estimated equilibrium climate sensitivity of about 2.5 or 3.3 °C when accounting for cloud and indirect aerosol effects.

Alternatively, you can take an estimate of anthropogenic effects (e.g. the calculated change in equilibrium climate mean temp), and from that you can derive a conclusion about the natural variation.

Recently there have been some studies and comments by a few climate scientists that based on the slowed global surface warming over the past decade, estimates of the Earth's overall equilibrium climate sensitivity (the total amount of global surface warming in response to the increased greenhouse effect from a doubling of atmospheric CO2, including amplifying and dampening feedbacks) may be a bit too high.

The estimated warming of 2.4 °C is the equilibrium warming above preindustrial temperatures that the world will observe even if GHG concentrations are held fixed at their 2005 concentration levels but without any other anthropogenic forcing such as the cooling effect of aerosols.
