WebFeb 24, 2024 · We explore the CO2 dependence of effective climate sensitivity (SG) with symmetric abrupt and transient CO2 forcing, spanning the range 1/8×, 1/4×, 1/2×, 2×, 4×, and 8×CO2, using two state-of-the-art fully coupled atmosphere-ocean-sea-ice-land models. In both models, under abrupt CO2 forcing, we find an asymmetric response in surface … Radiative forcing (or climate forcing ) is the change in energy flux in the atmosphere caused by natural or anthropogenic factors of climate change as measured by watts / meter². It is a scientific concept used to quantify and compare the external drivers of change to Earth's energy balance. System … See more Almost all of the energy that affects Earth's climate is received as radiant energy from the Sun. The planet and its atmosphere absorb and reflect some of the energy, while long-wave energy is radiated back into space.

Radiative Forcing Earthdata

WebRadiative forcing is a measure of how the energy balance of the Earth–atmosphere system is influenced. The word ‘radiative forcing’ is used because these factors change the … WebMany current applications use an “adjusted” radiative forcing in which the stratosphere is allowed to relax to thermal steady state, thus focusing on the energy imbalance in the Earth and troposphere system, which is most relevant to surface temperature change.

WebThe radiative forcing for CH 4 is determined in a way analogous to that for CO 2. For the increase of CH 4 from about 375 to about 675 ppb, ΔF CH4 ≈ 0.3 W·m –2. Thus, the total radiative forcing, ΔF, due to these two greenhouse gases is about 2.2 W·m –2. The predicted change in the average planetary surface temperature is WebRadiative forcing is the difference between incoming solar radiation and outgoing terrestrial radiation. This power, and thus the difference, is measured in watts per meter squared. …
