Indigenous communities adapt as climate change upends ecological calendars globally

WASHINGTON, May 9, 2023 — For millennia, Indigenous communities have timed their cultural, agricultural, and spiritual practices around Earth’s regular cycles — wet and dry, hot and cold, lush and barren seasons reliably indicated by seasonal changes in their environments. What happens when climate change upends these natural cycles, which are also called “ecological calendars”? […]

Half of U.S. Coastal Communities Underestimate Sea Level Risks

Many communities in the United States underestimate how much sea level will rise in their area, according to a new study in Earth’s Future led by Andra Garner, a climate scientist at Rowan University. Garner and colleagues compiled a database of the most recent regional climate projections in 54 locations across the continental United States and Puerto Rico and […]

Droughts are associated with increase in suicides in the U.S.

December 12, 2022 – Droughts may increase the rate of suicide in the United States, according to new research being presented at AGU’s Fall Meeting on 13 December in Chicago and online. The health impacts of drought are less understood than impacts from other types of natural disasters due to their slower nature compared to hurricanes, tornadoes […]

Climate change will cause Pacific’s low-oxygen zone to expand even more by 2100

WASHINGTON, November 29, 2022 — For thousands of kilometers along the western coasts of the Americas, low-oxygen waters known as oxygen minimum zones stretch out into the Pacific. In part due to climate change, this oxygen-starved region is likely to get wider and deeper, expanding by millions of cubic kilometers by the end of the […]

Mountain events could improve safety with ultra-high resolution weather models

In late May of 2021, 172 runners set out to tackle a 100-kilometer (62-mile) ultramarathon in northwestern China. By midday, as the runners made their way through a rugged, high-elevation part of the course, temperatures plunged, strong winds whipped around the hillslopes and freezing rain and hail pummeled the runners. By the next day, the […]

Climate change is shrinking and fragmenting salmon habitat in the Northwest

Salmon famously travel hundreds of miles upstream to reach their home waters to spawn, but climate change is shrinking their destination. A new study offers high-resolution details on how Chinook salmon habitats are being lost on Bear Valley Creek, a headwater stream of the Salmon River in central Idaho. The study, published today in the AGU journal Geophysical Research […]

Last Arctic Ice Refuge Is Disappearing

WASHINGTON November 12, 2019 – The oldest and thickest Arctic sea ice is disappearing twice as fast as ice in the rest of the Arctic Ocean, according to new research. A new study in AGU’s journal Geophysical Research Letters finds ice in the Arctic Ocean north of Greenland is more mobile than previously thought, as ocean currents and atmospheric […]

Climate change expected to accelerate spread of sometimes-fatal fungal infection: valley fever

WASHINGTON, Sept. 16, 2019 —Valley fever is endemic to hot and dry regions like the southwestern United States and California’s San Joaquin Valley, but a new study predicts climate change will cause the fungal infection’s range to more than double in size this century, reaching previously unaffected areas across the western U.S. In a new […]

Human-Caused Warming Likely Intensified Hurricane Harvey’s Rains

NEW ORLEANS, Dec. 13, 2017 – New research shows human-induced climate change increased the amount and intensity of Hurricane Harvey’s unprecedented rainfall. The new findings are being published in two separate studies and being presented in a press conference today at the 2017 American Geophysical Union Fall Meeting, along with additional new findings about recent […]
