Australian wildfires burning from December 2019 to January 2020 injected approximately 0.9 Tg of smoke into the stratosphere; this is the largest amount observed in the satellite era.
Future climate projections generally omit major volcanic eruptions but such events are likely to be important. In this work Dr. Man and colleagues show that projections of monsoon rainfall are importantly impacted by eruptions and could delay the time of emergence of anthropogenic influence by five years on average over about 60% of the GLM area.
The 2019 Northeast Pacific marine heatwave was amplified by natural, multi-decadal shoaling of the ocean mixed layer; anthropogenic mixed layer shoaling will amplify marine heatwaves in the future.
High ice water conditions (HIWC) can cause jet engine failure or damage. This study provides an analysis of the frequency and location of HIWC over most of the globe using space-borne radar and lidar observations.
As the COVID-19 pandemic took hold in the first half of 2020, humans around the world stopped moving and making, resulting in a 9% drop in the greenhouse gas emissions at the root of climate change.
The Climate Variability Diagnostics Package for Large Ensembles (CVDP-LE) developed by NCAR's Climate Analysis Section is an automated analysis tool and data repository for exploring internal and forced contributions to climate variability and change in coupled model “initial-condition” Large Ensembles and observations.
This study examines near-cloud environments from RELAMPAGO-CACTI to identify mesoscale ingredients affecting storm initiation. Null events arguably have the most convective potential but are limited ambient dry air.
We used an Earth system model and an offline fisheries model to demonstrate a serious decline in marine fisheries following a nuclear conflict. If we ran out of food on land due to darkening skies, we would not get much caloric relief from the ocean.
