Earth Energy Imbalance (EEI) Trends and Differences between Northern and Southern Hemispheres

Описание: Earth Energy Imbalance (EEI) Trends and Differences between Northern and Southern Hemispheres

In this controversial new preprint, it is argued that the Earth Energy Imbalance (EEI) increases over the past two decades for the northern hemisphere have been essentially balanced out in the southern hemisphere by wildfires and by the Hunga-Tonga volcano.

Interesting findings, that need to be confirmed by additional research groups, but definitely worth a video here.

Abstract
During the 21st century, Earth’s energy imbalance (EEI) at the top of the atmosphere has markedly increased, mainly due to an increase in absorbed shortwave (SW) rather than a decrease in outgoing longwave (LW) radiation. While previous studies, based on single-forcing (aerosol-only) experiments, linked reductions in anthropogenic aerosols to this positive SW trend, we find that both aerosol-radiation interactions and aerosol-cloud interactions have had a negligible impact on recent increases in the EEI. We estimate recent trends in effective radiative forcing due to aerosols using observations and reanalysis data. While aerosol concentrations have declined in the Northern Hemisphere (NH), wildfires and volcanic activity in the Southern Hemisphere (SH) have resulted in larger aerosol loading. This contrast effectively cancels out the total aerosol forcing, resulting in a negligible global impact on the EEI trend. Our findings also suggest that model-driven estimates may be overestimated, as they overlook the compensating effects of SH aerosol emissions that balance out NH reductions.
