Opinion: To assess marine cloud brightening's technical feasibility, we need to know what to study—and when to stop

Feb. 1, 2022

To avoid the worst impacts of climate change, it’s paramount that we decarbonize the economy and preserve and restore natural ecosystems.

Spurious Late Historical-Era Warming in CESM2 Driven by Prescribed Biomass Burning Emissions

Feb. 1, 2022

A spurious increase in the interannual variability of prescribed biomass burning (BB) emissions in the CMIP6 forcing database during the satellite era of wildfire monitoring (1997–2014) is found to lead to warming in the Northern Hemisphere extratropics in simulations with the Community Earth System Model version 2 (CESM2).

Great Plains storm intensity since the last glacial controlled by spring surface warming

Feb. 1, 2022

Mesoscale convective systems (MCSs) supply a substantial portion of warm-season rainfall to the Great Plains of North America, and they are responsible for severe weather and flooding across the central United States.

Multi-Century Changes in the Ocean Carbon Cycle Controlled by the Tropical Oceans and the Southern Ocean

Feb. 1, 2022

The oceanic absorption of anthropogenic carbon dioxide (CO2) is expected to continue in the following centuries, but the processes driving these changes remain uncertain

Air-sea coupling shapes North American hydroclimate response to ice sheets during the Last Glacial Maximum

Dec. 7, 2021

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.

On the Detection of COVID-Driven Changes in Atmospheric Carbon Dioxide

Dec. 7, 2021

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 role of bandwidth in setting the breaking slope threshold of deep-water focusing wave packets

Dec. 7, 2021

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.
