Warming Winters Sabotage Trees’ Carbon Uptake

by Grace van Deelen 31 July 202531 July 2025

In temperate forests, the biomass-building benefits of warmer growing seasons are offset by damaging variability in winter weather—a disparity that climate models may miss.

Verdaderas soluciones climáticas están debajo de nosotros

by Peter Reiners 29 July 202529 July 2025

Es momento de aceptar que el almacenamiento duradero de carbono en el subsuelo, junto con la reducción de emisiones, debe ser parte del plan para mitigar los efectos del cambio climático, y las geociencias deben desempeñar un papel central.

This Exoplanet May Have Grown Stranger as It Journeyed Starward

by Jonathan O’Callaghan 15 July 202515 July 2025

WASP-121b, an already unusual planet, might have a remote origin that explains some of its peculiar properties—from iron rain to the unexpected presence of methane.

Warming Gulf of Maine Buffers Ocean Acidification—For Now

by Kimberly Hatfield 3 July 20253 July 2025

Scientists constructed a 100-year history of acidity in the Gulf of Maine. They expected coastal variability but were surprised by what they didn’t find: a strong anthropogenic signal.

As Climate Changes, So Do Gardens Across the United States

by Grace van Deelen 28 May 202528 May 2025

Warmer winter temperatures have altered frost patterns and growing seasons across the United States, forcing botanical gardens and arboretums to adapt.

Old Forests in a New Climate

Eric Davidson, president-elect of AGU by Eric Davidson 15 May 202514 May 2025

It’s usually cooler under a forest than outside the forest, but that natural temperature buffering didn’t make global warming any less strong during the last 45 years in an old-growth forest of Oregon.

Real Climate Solutions Are Beneath Us

by Peter Reiners 2 May 202529 July 2025

It’s time to accept that durable subsurface carbon storage, along with emissions reductions, must be part of the plan to mitigate the effects of climate change—and geoscience must play a central role.
