Recent reductions in emissions of tiny particles, the major cause of air pollution globally, have led to more heat in the Earth's climate system. This is shown in a new international study led by CICERO and published in Communications Earth & Environment.
Study presents evidence that recent reductions in aerosol emissions create an additional warming effectSatellite observations vs. three different model simulations showing contributions to the 2001–2019 trend in Earth’s energy imbalance. Credit: Adapted fromRecent reductions in emissions of tiny particles, the major cause of air pollution globally, have led to more heat in the Earth's climate system.
"Our study makes novel use of models and observations to explain why the Earth's energy imbalance is increasing so much.
Another co-author of the study, research director Gunnar Myhre at CICERO, says that"the additional warming effect that comes from removal of cooling particles is something researchers have anticipated would happen for a long time, and does not come as a surprise in that sense, but now we have the evidence. Also, the strong impact that the particle emission reductions had on adding to the Earth's energy imbalance in the past two decades was an eye-opener.

Study links Earth's warming climate to pollen and longer allergy seasonAccording to a study, as more carbon is released into the atmosphere, those molecules help trap heat from the sun. This helps gradual warming, which means warming temps can occur earlier in the year, and plants release pollen sooner.
