Extreme precipitation in Central Asia connected to drought in mainland Southeast Asia

Phys.org: Earth science - Tue, 07/21/2026 - 19:10
In much of Asia, the effects of climate change are felt through an increased frequency of extreme weather events, especially water-related ones. Droughts are becoming more common in mainland Southeast Asia, while periods with unusually large amounts of rainfall are increasing in Central Asia. Rice University's Na Wang and Sylvia Dee were interested in understanding whether these two extremes were related, despite being geographically distant. The researchers' findings were recently published in Nature Geoscience.

Urgent action is needed to protect Somalia from a potentially unprecedented weather event, experts warn

Phys.org: Earth science - Tue, 07/21/2026 - 17:20
Cardiff University leads a multidisciplinary research collaboration representing academia and multiple nongovernmental organizations (NGOs) to explore Somalia's 2023 El Niño floods and lessons learned from a similar event in 1997. The research, which has yet to undergo peer review, was released as a preprint on Earth ArXiv because academics believe the situation ahead of this year's Deyr season—the secondary, shorter rainy season in the Horn of Africa, typically running from October to December—could be much more serious, and the findings have urgent implications for planning now.

Low cloud-cover has helped mute warming for the last 47 years, but models predict this will change

Phys.org: Earth science - Tue, 07/21/2026 - 17:10
A recent study, published in Geophysical Research Letters, combines historical satellite observations with atmospheric reanalysis data to construct a multidecade record of low-cloud cover in the hope of improving current climate models.

Geophysics brings clarity to the potential of natural hydrogen

Phys.org: Earth science - Tue, 07/21/2026 - 14:20
Natural hydrogen is considered a potential low-carbon energy source. But how much is generated underground—and how quickly? An international research team led by the LIAG Institute for Applied Geophysics in Hannover has published the first process-based estimates for the Western Pyrenees and Northern California in Nature Communications. The calculated production rates are lower than earlier theoretical estimates. The study's new evaluation method, through the open-source tool PoNHy, allows more realistic assessments and can be applied to other regions to identify promising geological systems more precisely and evaluate their potential.

Triassic inferno: Fires raged across Europe for millennia during past global warming

Phys.org: Earth science - Tue, 07/21/2026 - 13:20
The end-Triassic mass extinction, 201 million years ago, is linked to volcanism that resulted from the break-up of Pangea and which pumped out vast amounts of CO2 into the atmosphere, causing extreme global warming of 5 to 10 degrees Celsius. As a result, tree-dominated vegetation collapsed and the highly disturbed landscapes were colonized by ferns that formed savannahs across large swaths of what is now Northwest Europe.
