WebJul 23, 2024 · In 1979, a groundbreaking report led by Massachusetts Institute of Technology scientist Jule Charney—dubbed the “Charney … Climate sensitivity can be estimated using the observed temperature increase, the observed ocean heat uptake, and the modelled or observed radiative forcing. The data are linked through a simple energy-balance model to calculate climate sensitivity. See more Climate sensitivity is a measure of how much Earth's surface will cool or warm after a specified factor causes a change in its climate system, such as how much it will warm for a doubling in the atmospheric carbon dioxide … See more Depending on the time scale, there are two main ways to define climate sensitivity: the short-term transient climate response (TCR) … See more Climate sensitivity has been defined as the short- or long-term temperature change resulting from any doubling of CO2, but there is evidence … See more Historical estimates Svante Arrhenius in the 19th century was the first person to quantify global warming as a consequence … See more The rate at which energy reaches Earth as sunlight and leaves Earth as heat radiation to space must balance, or the total amount of heat energy on … See more Radiative forcing is one component of climate change. The radiative forcing caused by a doubling of atmospheric CO2 levels (from the pre-industrial 280 ppm) is approximately 3.7 See more Different forcing agents, such as greenhouse gases and aerosols, can be compared using their radiative forcing, the initial radiative imbalance averaged over the entire globe. Climate sensitivity is the amount of warming per radiative forcing.
