However, the extent to which they reflect solar energy depends heavily on how much water the particles can absorb. This so-called hygroscopicity has so far been represented in a simplified manner in climate models. An international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has now demonstrated through a global study that the models are not precise enough, particularly in urban regions. https://phys.org/news/2026-05-urban-aerosols-faster-polluted-air.html Earth Sciences Wed, 20 May 2026 16:00:10 EDT news698501755 Sea level rise is a direct consequence of human-induced climate change: global warming. It is relentless and very hard to stop. It arises from human-induced warming and the consequential expansion of the ocean, plus the addition of more and more water from melting glaciers and ice sheets. It will continue long into the future. https://phys.org/news/2026-05-scientists-knowledge-sea.html Earth Sciences Wed, 20 May 2026 14:00:07 EDT news698493661 Old oil and gas wells may continue to affect the environment long after they have stopped producing, with new field evidence showing that their leakage footprint can be broader and more persistent than surface methane measurements alone reveal. A study led by researchers at The Lyell Centre, Heriot-Watt University, examined persistent methane leakage from a legacy petroleum well in British Columbia, Canada. The team found that while methane emissions at the ground surface were concentrated in a relatively small area and varied through time, the leakage also left a wider detectable signature in the shallow subsurface and surrounding soils. https://phys.org/news/2026-05-field-evidence-canada-wells-hidden.html Earth Sciences Wed, 20 May 2026 12:44:20 EDT news698499741 A recent study published in Advances in Atmospheric Sciences has uncovered a detailed mechanism through which intense storms over the Himalayas contribute to increasing moisture in the lower stratosphere—a layer of the atmosphere crucial to global climate regulation.
