Rapid surge in global warming mainly due to reduced planetary albedo

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research
Peer-Reviewed Publication

Rising sea levels, melting glaciers, heatwaves at sea – 2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees above the preindustrial level, another record. Seeking to identify the causes of this sudden rise has proven a challenge for researchers. After all, factoring in the effects of anthropogenic influences like the accumulation of greenhouse gases in the atmosphere, of the weather phenomenon El Niño, and of natural events like volcanic eruptions, can account for a major portion of the warming. But doing so still leaves a gap of roughly 0.2 degrees Celsius, which has never been satisfactorily explained. A team led by the Alfred Wegener Institute puts forward a possible explanation for the rise in global mean temperature: our planet has become less reflective because certain types of clouds have declined.

3D models help researchers understand the climate impact of eddies

Ocean-Land-Atmosphere Research (OLAR)

Mesoscale eddies are ocean vortices less than 100 kilometers in diameter that are responsible for the localized “weather” of the oceans. Because of the large amount of mass and energy movement associated with these currents, mesoscale eddies play an integral role in determining Earth’s climate. A group of oceanographers wrote a review article outlining how to best model the 3D structure of mesoscale eddies over time to better predict future changes in climate.

Smartphones can alert us to wildfires and extreme weather conditions

Tel-Aviv University
Peer-Reviewed Publication

A new study from Tel Aviv University has found that the smartphones we all carry in our pockets could help collect weather data from the public to provide early warnings for extreme weather, such as wildfires.

Lessons from Earth's hottest epoch in the last 65 million years: How global warming could shrink the tropics' rain belt

Institute of Atmospheric Physics, Chinese Academy of Sciences
Peer-Reviewed Publication

Researchers from the Institute of Atmospheric Physics at the Chinese Academy of Sciences used climate simulations and reconstructions of ancient climate conditions to uncover a striking pattern: extreme warming expanded subtropical dry zones and shrank tropical wet regions in the early Eocene.

USC-led CLIMA Center awarded $4.1 million by NIH to study impact of wildfire smoke and extreme heat on human health

Keck School of Medicine of USC
Grant and Award Announcement

From devastating wildfires and landslides to droughts and extreme heat waves, climate-related events disrupt the lives of communities around the world. How these events impact the health of Los Angeles’s vulnerable communities is a question numerous USC researchers are working to solve. The National Institutes of Health (NIH) has awarded $4.1 million to a USC-led initiative to build a community of transdisciplinary scientists and a robust infrastructure with the goal of advancing solution-oriented climate change adaptation and health research. The center is called CLIMA, short for the CLIMAte-related Exposures, Adaptation and Health Equity Center. CLIMA researchers have been collaborating with USC Dornsife Public Exchange and the City of Los Angeles Climate Emergency Mobilization Office (CEMO) to build a visual mapping tool called a StoryMap, which can add narrative context to the city and county’s extreme heat challenges. By combining Geographic Information System (GIS) mapping with accessible climate storytelling, the StoryMap can inform the public about the risks associated with extreme heat, as well as provide resources for and information regarding the City of Los Angeles’ #HeatRelief4LA campaign.
