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.


Coupled Climate Responses to Recent Australian Wildfire and COVID-19 Emissions Anomalies Estimated in CESM2

Oct. 1, 2021

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.

Arctic Cyclones and Their Interactions With the Declining Sea Ice: A Recent Climatology

June 22, 2021

In this study, we applied a cyclone tracking algorithm to multiple reanalyses and categorized the detected cyclones based on season, intensity, and sea ice state to provide an Arctic cyclone climatology with emphasis on cyclone-sea ice interactions over the Arctic Ocean and adjacent waters.

Arctic open-water periods are projected to lengthen dramatically by 2100, UM study

June 15, 2021

The Arctic open-water season is projected to lengthen by 2100, with a strong impact of future emission scenarios. For each 1 °C of warming, the open-water period increases by 1 months. That means that under the strong CMIP6 warming scenario, the projected open-water period exceeds 6 months for most of the Arctic by 2100.
