Environmental phenomena and their consequences can disrupt social structures and destabilize political systems. An interdisciplinary research team demonstrated this using the example of the late Tang dynasty in medieval China. https://phys.org/news/2026-01-collapse-tang-dynasty-climate-played.html Earth Sciences Thu, 15 Jan 2026 12:19:41 EST news687701941 A new study analyzed nearly four decades of deep ocean observations to reveal significant cooling and freshening of deep water in the Subtropical North Atlantic. The results suggest that warmer, saltier deep waters observed across other parts of the Atlantic may reach the region within the next 10 years, potentially influencing large-scale sea level changes and altering the flow of ocean currents in the region. https://phys.org/news/2025-03-shifts-subtropical-north-atlantic-ocean.html Earth Sciences Wed, 26 Mar 2025 12:10:05 EDT news662209345 Researchers at Stanford and Colorado State University have developed a rapid, low-cost approach for studying how individual extreme weather events have been affected by global warming. Their method, detailed on Aug. 21 in Science Advances, uses machine learning to determine how much global warming has contributed to heat waves in the U.S. and elsewhere in recent years. https://phys.org/news/2024-08-ai-link-global.html Earth Sciences Wed, 21 Aug 2024 14:00:01 EDT news643449601 Adding crushed volcanic rock to cropland could play a key role in removing carbon from the air. In a field study, scientists at the University of California, Davis, and Cornell University found the technology stored carbon in the soil even during an extreme drought in California. The study was published in the journal Environmental Research Communications. https://phys.org/news/2023-10-adding-farmland-carbon-air-field.html Earth Sciences Tue, 24 Oct 2023 13:03:03 EDT news617371381 Tens of thousands of thunderstorms may rumble around the world each day, but accurately predicting the time and location where they will form remains a grand challenge of computer weather modeling. A new technique combining underused satellite and radar data in weather models may improve these predictions, according to a Penn State-led team of scientists. https://phys.org/news/2023-03-underused-satellite-radar-thunderstorm.html Earth Sciences Thu, 09 Mar 2023 13:20:29 EST news597590426 Extreme weather and ocean events are on the rise around the world, due largely to human-caused climate change. But to fully understand these changes—and, ideally, to predict when and where they may occur in the future—researchers and policymakers must also take into account naturally occurring climate variability, suggests new research published in Nature Communications and led by the University of Colorado Boulder. https://phys.org/news/2022-12-human-caused-global-natural-climate-variability.html Environment Mon, 12 Dec 2022 09:06:05 EST news590058362 Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves—and moving towards dangerous wildfires and warmer temperatures, finds one of the largest studies of U.S. migration and natural disasters. https://phys.org/news/2022-12-flocking-wildfires-dont-deter-americans.html Environment Thu, 08 Dec 2022 00:00:02 EST news589653798 In people, Type 1 diabetes mellitus diagnoses are more common in northern latitudes and during winter. Now a new study shows a similar pattern in dogs. https://phys.org/news/2022-08-cooler-temps-northern-climes-diabetes.html Plants & Animals Tue, 16 Aug 2022 11:33:03 EDT news579868381 A team based at Princeton University has accurately simulated the initial steps of ice formation by applying artificial intelligence (AI) to solving equations that govern the quantum behavior of individual atoms and molecules. https://phys.org/news/2022-08-simulation-artificial-intelligence-ice.html General Physics Mon, 08 Aug 2022 15:00:01 EDT news579174348 The critical zone is Earth's outer skin, the space between treetops and bedrock. The critical zone is a community comprising rock, water, soil, air, and the flora and fauna that live on Earth's surface. As floods, landslides, and other geologic hazards shape landscapes, they transform the critical zone and the life-giving processes that support ecosystems. https://phys.org/news/2021-11-theory-tree-uprooting-sediment-movement.html Earth Sciences Mon, 22 Nov 2021 10:10:52 EST news556798247 Scientists from Finland and Germany used bacteria as an example to study how communities consisting of several species respond to disturbances in their laboratory environment. Similar kinds of perturbations can occur in the human gut when antibiotic medication is applied, resulting, for example, in diarrhea. Also global warming and extreme weather conditions such as persistent drought periods can disturb many kinds of organismal communities. https://phys.org/news/2020-08-multi-species-bacterial-environmental-disturbances.html Ecology Mon, 10 Aug 2020 11:00:05 EDT news516268121 A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures. https://phys.org/news/2019-05-confidence-nasa-earth-temperature.html Earth Sciences Thu, 23 May 2019 12:48:14 EDT news477834480 A team of UK researchers believe earthworms could provide a window into past climates, allowing scientists to piece together the prevailing weather conditions thousands of years ago. https://phys.org/news/2013-07-earthworms-scientists-climates.html Earth Sciences Mon, 08 Jul 2013 11:28:02 EDT news292501670 A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science. https://phys.org/news/2012-07-satellite-reveals-smaller-volcanoes-cool.html Earth Sciences Thu, 05 Jul 2012 14:55:41 EDT news260718870
