Quantifying Ground Ice Meltwater Contribution to River Runoff

In a warming climate, the sustainable development of cryospheric meltwater on the Tibetan Plateau has sparked worries because of its significance for the fragile ecosystem in the headwater regions and the dense populations downstream.

Arctic Dust with High Ice Nucleating Ability Impacts Arctic Clouds

Investigators from Nagoya University and Japan’s National Institute of Polar Research discovered that dust from land without snow cover in the Arctic is a significant source of particles that form ice crystals in the Arctic’s low-level clouds (at altitudes below about 3 km) during summer and fall.

Persistent Marine Heat Waves Linked to Seabird Die-Offs

Seabirds, from cormorants to puffins, spend most of their lives at sea. Beloved by birdwatchers, these animals can be hard to study because they spend so much time far from shore.

Study Finds Irrigation Can Have Complex Effects on Precipitation in Mid-Atlantic

Scientists know that urbanization and irrigation can significantly influence rainfall. However, they don't fully know how these effects vary among different types of rain. Researchers investigated how large-scale urbanization and irrigation in the United States affect the three dominant types of summer precipitation in the mid-Atlantic region.

Aerosol-Driven Changes in Ocean Circulation More Effective than GHGs in Altering Oceanic Heat Distribution

Anthropogenic aerosols - aerosols originating from human activity - and greenhouse gases, or GHGs, have helped modulate the storage and distribution of heat in oceans since the industrial age. Isolating and quantifying the effects of both forcers using coupled climate model simulations, a University of California, Riverside-led team has found that anthropogenic aerosols and GHGs have played distinct roles in the world's oceans in shaping the pattern of heat uptake, redistribution, and storage.

“Heat Domes” Likely to Become More Frequent and Intense as the Climate Crisis Worsens

For now, it isn’t budging. But eventually, the “heat dome” that has parked itself over Texas and is sending temperatures soaring to triple digits will expand to other parts of the nation, putting millions more people at risk and further straining an already-overwhelmed power grid.
