The Barents Sea is a cooling machine. To predict how ocean currents in the Atlantic Ocean may develop, one needs to know what drives them. The hunt for driving forces has led researchers to follow the warm water from the Gulf Stream as far north as it gets. https://phys.org/news/2026-06-arctic-sea-ice-loss-reshape.html Earth Sciences Mon, 15 Jun 2026 16:00:10 EDT news700755121 Researchers have developed a new approach using data from NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite to observe the timing and progression of fall colors across landscapes. https://phys.org/news/2026-06-pace-satellite-tracks-fall-daily.html Earth Sciences Mon, 15 Jun 2026 14:20:04 EDT news700744981 The Arctic and northern high latitudes are warming about 2–4 times faster than the global average, allowing ancient permafrost to thaw and release stored carbon. These permafrost soils currently store roughly one-third of the world's organic soil carbon, much of which has remained frozen for thousands of years. As the soils thaw, organic matter from dead plants and animals within them starts to decompose, and greenhouse gases, including carbon dioxide, are released. https://phys.org/news/2026-06-northern-permafrost-carbon-source-earlier.html Earth Sciences Mon, 15 Jun 2026 12:59:59 EDT news700747125 Changes in wind patterns play the leading role in influencing often devastating tropical rainfall changes, rather than simply the warming atmosphere holding more moisture, according to new research. https://phys.org/news/2026-06-patterns-play-role-tropical-rainfall.html Earth Sciences Mon, 15 Jun 2026 11:20:10 EDT news700735921 Planting trees is widely promoted as a natural solution to climate change.

Human activities pushed global warming to 1.37°C in 2025, and its level is projected to surpass 1.5°C in about four years. Crucially, the rate at which heat is accumulating in Earth's system suggests high levels of future warming. These are some of the key findings from the latest Indicators of Global Climate Change (IGCC) report, published in Earth System Science Data. https://phys.org/news/2026-06-global-137c-earth-accumulating.html Earth Sciences Wed, 10 Jun 2026 18:10:01 EDT news700241521 For almost a century, researchers have known that vertical land motion—the lifting and sinking of the ground—affects sea level locally. As the ground sinks, the sea level rises relative to the land. Scientists also assumed this process generally occurred at a steady rate over time. But a research team that includes Thomas Wahl, a UCF researcher and associate professor in the Department of Civil, Environmental and Construction Engineering, has found that ground subsidence has undergone phases of variable change, creating significant implications for coastal communities. https://phys.org/news/2026-06-coastal-shifts-reveal-faster-local.html Earth Sciences Wed, 10 Jun 2026 17:50:02 EDT news700328101 Ice-age sea-level declines may have turned seafloor volcanoes into natural iron fertilizer for plankton, potentially enhancing ocean carbon storage, Boston College researchers report in the journal Nature Geoscience. https://phys.org/news/2026-06-ice-age-sea-falls-seafloor.html Earth Sciences Wed, 10 Jun 2026 15:40:02 EDT news700314301 The Arizona sunshine hits like a blowtorch.
