Featured Research

Acidity, heat, and deoxygenation pose triple threat to oceans
Ocean acidification, warming and deoxygenation events can damage ocean ecosystems and structures on their own. When all three hit at once, the impacts are amplified, reducing habitable space. About 20% of the world’s oceans — mostly in the North Pacific — are vulnerable to this triple threat. Triple-threat events have become larger, more intense, and longer-lived since the 1960s.

Urban wetlands could help save this historic Chilean city from flooding
Valdivia, near the Chilean coast, is a city of wetlands; they cover nearly a quarter of its area. The spot was home to one of the Americas’ oldest cultures, which used the wetlands to flourish. Today, the city’s 166,000 inhabitants could lean on the wetlands once more — this time to alleviate flooding from climate change. But development threatens wetland loss. [Earth’s Future research]

Climate change cuts critical rice production in India’s Uttar Pradesh
India has the largest area of rice agriculture of any country, but hotter temperatures and shorter growing seasons will curb rice production by up to 20% by the end of the century in Uttar Pradesh, the most populous Indian state, a new study finds. Increases in rainfall may reduce the need for irrigation, but climate change will lower rice yields overall. [Earth’s Future research]

Jupiter’s magnetosphere has a semi-open relationship with the solar wind
Scientists have long debated whether Jupiter’s massive magnetosphere interacts with solar wind. Using data from NASA’s Juno mission, a new study models the magnetosphere with unprecedented accuracy and finds the answer is: sometimes. [Eos editor’s highlight][AGU Advances research]

AGU (www.agu.org) is a global community supporting more than half a million advocates and professionals in Earth and space sciences. Through broad and inclusive partnerships, AGU aims to advance discovery and solution science that accelerate knowledge and create solutions that are ethical, unbiased and respectful of communities and their values. Our programs include serving as a scholarly publisher, convening virtual and in-person events and providing career support. We live our values in everything we do, such as our net zero energy renovated building in Washington, D.C. and our Ethics and Equity Center, which fosters a diverse and inclusive geoscience community to ensure responsible conduct.
