A new study warns against oversimplifying the causes of extreme weather. While the Asian monsoon can influence North American climate, researchers found its usual effect is to cool the Pacific Northwest. However, during the 2021 heatwave, a uniquely strong jet stream acted as an "atmospheric waveguide," redirecting the monsoon's energy and amplifying the heat. This shows that a factor's general influence ("can it?") can differ from its role in a specific event ("did it?"), highlighting the need for detailed, case-by-case analysis.

A Weill Cornell Medicine investigator and other members of a technical advisory group to the World Health Organization and United Nations Children’s Fund have outlined measures that nations can take to ensure that children’s health is accounted for within climate change goals. 

The impact of water expulsion into the open ocean from formerly ice-covered areas means that sea levels will change world-wide. Ambarish Karmalkar in the University of Rhode Island's Climate Dynamics Lab recently collaborated on a project to simulate and predict ice sheet-climate interactions in the coming decades, to better understand Antarctica’s potential sea level contributions.

UN agency for digital technologies urges collective action in Belém to harness digital technologies and achieve sustainability goals

Climate change is changing the size of fishes in Michigan's inland lakes, leaving the young and old of many species more vulnerable to predation

New University of Washington-led research attributes accelerated warming to reduced cloud reflectivity. As efforts to improve air quality have reduced pollution, clouds became less mirror-like, letting more solar radiation reach Earth and revealing the true impact of greenhouse gases.
