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 aerosolsā€”the small particles that make up smog and air pollutionā€”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 Antarctica's patterns of stark seasonal changes, with months of darkness followed by a summer of 24-hour daylight, prompted us to explore how a Māori lunar and environmental calendar (Maramataka) might apply to the continent and help us recognize changes as the climate continues to warm. /news/2025-07-antarctica-mori-lunar-calendar-track.html Environment Wed, 16 Jul 2025 12:00:01 EDT news671885536 Glaciers hold layers of history preserved in ice, offering unique insights into Earth's past that can also help us interpret the future.

Although fire occurs nearly everywhere on Earth and has always been present, it is still one of the least understood components of the Earth system. Recently, unprecedented fire activity has been observed in boreal (northern) and Arctic regions, which has drawn the scientific community's attention to areas whose role in the future of our planet remains a mystery. Climate change likely has a major role in this alarming trend. However, high-latitude wildfires are not just a symptom of climate change; they are an accelerating force that could shape the future of our climate in ways that we are currently incapable of predicting. /news/2025-06-high-latitude-peat-forest-future.html Environment Wed, 25 Jun 2025 18:10:01 EDT news670084450 Iceland is one of the most active volcanic regions in the world, but its seismic nature is part of a much broader geological history. /news/2025-06-north-atlantic-volcanic-secrets-thin.html Planetary Sciences Tue, 24 Jun 2025 15:00:17 EDT news669996005 This past winter, researchers from the Center for Earth Observation Science (CEOS) at the University of Manitoba (UM) completed the first-ever controlled oil spill experiment at the Churchill Marine Observatory (CMO).
