Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper published in Nature Communications. "The Greenland coastline is going to experience quite a different outcome," says lead author Lauren Lewright, a Ph.D. student in geophysics working at the Lamont-Doherty Earth Observatory, which is part of the Columbia Climate School. "Sea level in Greenland is actually projected to fall." https://phys.org/news/2026-01-sea-greenland-fall.html Earth Sciences Mon, 26 Jan 2026 15:07:42 EST news688662421 As Earth warms due to climate change, oceans are heating up, becoming more acidic, and losing oxygen. These changes threaten marine life, food webs, and global fisheries. Scientists agree that cutting greenhouse gas emissions is essential, but current efforts are not enough to keep global warming below the 1.5–2 degrees Celsius targets set by the Paris Agreement. Because of this, researchers are exploring climate intervention strategies as possible additions to emissions cuts. https://phys.org/news/2026-01-scientists-key-oceanic-unknowns-climate.html Earth Sciences Sat, 17 Jan 2026 16:10:01 EST news687629168 Climate change is already fueling dangerous heat waves, raising sea levels and transforming the oceans.

It's the second most important contributor to climate change after carbon dioxide. However, quantifying the exact amount being released has been a matter of guesswork. But now the first-ever global map of methane leaks from industrial sites is giving us detailed information on where this greenhouse gas is escaping, how much is escaping, and how often it occurs. https://phys.org/news/2025-12-global-fleet-satellites-methane-leaks.html Earth Sciences Tue, 16 Dec 2025 10:35:08 EST news685103536 A new international study led by McGill University in collaboration with Jefo Nutrition shows that supplementing dairy cow diets with microencapsulated B-vitamins can significantly reduce greenhouse gas emissions while increasing milk yield and quality.
