Decline in aerosols could lead to more heat waves in populated areas Heat waves are becoming more frequent around the world. And while rising temperatures caused by greenhouse gas emissions are part of the problem, the declining levels of aerosols—the small particles that make up smog and air pollution—may be driving the rise even more, particularly in populated areas. /news/2025-07-decline-aerosols-populated-areas.html Environment Wed, 16 Jul 2025 15:27:33 EDT news671898447 Scientists find the first ice core from the European Alps that dates back to the last Ice Age Glaciers hold layers of history preserved in ice, offering unique insights into Earth's past that can also help us interpret the future. Trapped amidst the frozen water are microscopic deposits of dust, pollen, and even pollutants that scientists can use to examine environmental changes through time. /news/2025-07-scientists-ice-core-european-alps.html Earth Sciences Environment Wed, 16 Jul 2025 07:30:02 EDT news671868207 Sugars from the salty ocean are responsible for a large part of the ice nuclei over southern hemisphere Current climate models have so far been unable to adequately reproduce the clouds over the Southern Ocean around Antarctica. An international team has now taken an important step toward filling this gap. The researchers were able to prove that the majority of ice nuclei in the atmosphere there are due to sugar compounds from marine microorganisms in the seawater. /news/2025-07-sugars-salty-ocean-responsible-large.html Environment Tue, 15 Jul 2025 10:50:08 EDT news671793102 Theory for aerosol droplets from contaminated bubbles may shed light on spread of pollution, microplastics, and more Bubbles burst when their caps rupture. Children discover this phenomenon every summer day, but it also underpins key mechanisms for the spread of pollutants, contaminants, and even infectious disease through the generation of aerosol droplets. While bubble bursting has been extensively studied in pure substances, the impact of contaminants on bursting dynamics has not received widespread attention. /news/2025-07-theory-aerosol-droplets-contaminated-pollution.html Soft Matter Tue, 15 Jul 2025 03:32:04 EDT news671769119 Air pollution cuts in East Asia likely accelerated global warming The cleanup of air pollution in East Asia has accelerated global warming, a new study published today (Monday, 14 July) in the journal Communications Earth and Environment has found. /news/2025-07-air-pollution-east-asia-global.html Earth Sciences Environment Mon, 14 Jul 2025 05:00:02 EDT news671448431 Mathematical model clarifies scaling regimes in Lagrangian turbulence evolution A sneeze.

During major blazes in 2023, the smoke tinted the New York sky orange and drifted as far south as New Orleans. These blazes have surged in the last decade due to the effects of climate change—warmer summers, less snow cover in the spring, and the loss of sea ice.
