More intense non-tropical storms causing increased rainfall in Southeast U.S.
A new study in AGU’s journal Geophysical Research Letters examined the region’s precipitation records from 1895 to 2018. The new research found precipitation in the Southeast during the fall increased by almost 40 percent in the past century due to an increase in average daily rainfall rather than the overall number of storms.

How the Pacific Ocean influences long-term drought in the Southwestern U.S.
New research explores what conditions in the ocean and in the atmosphere prolong droughts in the Southwestern U.S. The answer is complex, according to a study published Aug. 6 in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union.

Geoengineering versus a volcano
Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun’s radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new paper in the AGU journal Geophysical Research Letters investigates.

Ancient plankton help researchers predict near-future climate
Temperature data inferred from plankton fossils from the Pliocene, an era with CO2 levels similar to today’s, allowed a research team to rectify discrepancies between climate models and other proxy temperature measurements.

Decades-old pollutants melting out of Himalayan glaciers
New research in AGU’s Journal of Geophysical Research: Atmospheres finds chemicals used in pesticides that have been accumulating in glaciers and ice sheets around the world since the 1940s are being released as Himalayan glaciers melt as a result of climate change.

Study finds increased moisture facilitated decline in African fires in Africa
The amount of area burned across Africa declined by 18.5 percent between 2002 and 2016, according to a new study.

Climate change is transforming northernmost Arctic landscapes
Isachsen, a permafrost monitoring site that sits at a latitude of 78 degrees north on the Arctic Canadian island of Ellef Ringnes, seemed like the last place that would feel the effects of climate change.

Atmospheric rivers getting warmer along U.S. West Coast
Most of the West Coast of the United States relies on a healthy winter snowpack to provide water through the dry summer months. But when precipitation falls as rain rather than snow, it can diminish summer water supplies, as well as trigger floods and landslides. A new study in AGU’s Journal of Geophysical Research: Atmospheres finds atmospheric rivers –plumes of moisture that deliver much of the west’s precipitation—have gotten warmer over the past 36 years.

Climate change may shift timing of summer thunderstorms
Climate change could affect the regularity of summer afternoon thunderstorms in some parts of the world, according to new research. A new study in the AGU journal Geophysical Research Letters modeled weather patterns in western Germany, northern France and parts of Belgium, the Netherlands and Luxembourg, under climate change.

Feeling Heat on the Roof of the World
The Tibetan Plateau, also known as the “roof of the world,” is getting hotter. This process is especially fast in places marked by retreating snow, according to new research.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
