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.
Using numerical simulations and wave tank observations, we found that both the slope and bandwidth of a wave packet can determine if a deep water ocean wave breaks or not.
The physical circulation of the Southern Ocean sets the surface concentration and thus air-sea exchange of urn:x-wiley:00948276:media:grl63112:grl63112-math-0001.
After Hurricane Maria, multiple U.S. Department of Energy laboratories studied the state of the electric grid in Puerto Rico and analyzed grid resilience and grid integration of renewable energy.
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.
Over 80 international participants, representing weather, climate, and energy systems research, joined two 4-h remote sessions to highlight and prioritize ongoing and future challenges in energy–climate modeling.
