Heatwaves hitting Antarctica too now

Sept. 8, 2023

The world saw another year full of extreme weather events resulting from climate change in 2022, from intense storms to soaring temperatures and rising sea levels.


On the Links Between Ice Nucleation, Cloud Phase, and Climate Sensitivity in CESM2

Sept. 5, 2023

Ice nucleation in mixed-phase clouds influences climate projections. McGraw et al. show that total cloud feedback is independent of ice nucleation scheme when cloud phase is matched to satellite retrievals, showing the need to capture observed cloud phase to predict future change.


Improved tropical deep convective cloud detection using MODIS observations with an active sensor trained machine learning algorithm

Sept. 5, 2023

A deep convective cloud (DCC) detection approach for MODIS observations is developed with a CloudSat trained machine learning model. This approach provides high temporal and spatial resolution DCC distributions to support intra-seasonal to interannual climate variability studies.


Nonstationary Roles of Regional Forcings in Driving Low-Frequency Sea Level Variability Along the U.S. East Coast Since the 1950s

Sept. 5, 2023

The nonstationary roles of regional forcings from alongshore wind stress and sea level pressure (SLP) in driving low-frequency (interannual-to-decadal) sea level variability along the U.S. east coast for the 1959–2020 period are investigated.

Following the pandemic, CIRES students venture out of the lab and classroom.


Clouds Increasingly Influence Arctic Sea Surface Temperatures as CO2 Rises

May 1, 2023

As Arctic sea ice retreats during the melt season, the upper ocean warms in response to atmospheric heat fluxes.


Colder Eastern Equatorial Pacific and Stronger Walker Circulation in the Early 21st Century: Separating the Forced Response to Global Warming From Natural Variability

Feb. 6, 2023

Since the early 1990s the Pacific Walker circulation shows a multi-decadal strengthening, which contradicts future model projections.
