The American Association for the Advancement of Science (AAAS), the world’s largest general scientific society, today announced that ATOC Professor Brian Toon will join the ranks of its newest class of AAAS Fellows.
US West Coast rainfall was VERY different during the last ice age, why? We use new CESM experiments to find out! Take home point - North Pacific ocean temps, not ice sheets directly, responsible for hydroclimate shifts.
COVID pandemic lockdowns suddenly slowed the rate at which we burned fossil fuels and released carbon dioxide into the atmosphere, yet we cannot find any significant reductions in the growth of carbon dioxide in the atmosphere from our measurements.
The climate effects of COVID-19 restrictions and the 2019/20 Australian bushfire season are simulated in 50-member CESM2 ensembles. Australian bushfires are found to have had a bigger impact on global climate than pandemic lockdowns and may have influenced ENSO.
