Teeth of a Camarasaurus, found in the Morrison Formation, USA, which were also analyzed in the research. Credit: Sauriermuseum Aathal A new method allows scientists to reconstruct carbon dioxide levels and photosynthesis from fossilized tooth enamel. A surprising new line of evidence is providing fresh insights into Earth’s ancient climate. Fossilized dinosaur teeth reveal that the atmosphere during the Mesozoic …

Facebook Tweet Email Link Just southwest of New Orleans, in a tranquil fishing village on the Louisiana bayou, Linard Lyons spent the morning on his 19-foot boat, preparing crab traps for his grandchildren just like he had done thousands of times before. This time, he noticed a tiny scratch on his leg – a scratch that nearly cost him his …

Environmental scientists are increasingly using enormous artificial intelligence models to make predictions about changes in weather and climate, but a new study by MIT researchers shows that bigger models are not always better. The team demonstrates that, in certain climate scenarios, much simpler, physics-based models can generate more accurate predictions than state-of-the-art deep-learning models. Their analysis also reveals that a …

The melting of Antarctic sea ice may be even worse than we realized. New research suggests that the region is experiencing rapid and abrupt disruptions that could represent a global climate “tipping point,” past which the effects of climate change become irreversible and accelerate in intensity.  “Antarctica is showing worrying signs of rapid change across its ice, ocean and ecosystems,” …

Satellite data, as revealed in a 2025 study published in Earth’s Future, confirms that sea levels are rising faster than expected, validating decades-old climate projections. Since the 1990s, satellites have provided precise measurements, showing an accelerating rise that underscores the growing risks for coastal areas. This data supports early climate models, proving that our understanding of sea-level rise was more …

This story originally appeared on Vox and is part of the Climate Desk collaboration. Air conditioners have been working overtime this hot summer, from those tiny window units to the massive AC towers that serve the tightly packed apartment buildings in major cities. And while they bring the relief of cool air, these contraptions also create the conditions for dangerous …

Hurricane Erin continued to churn in the North Atlantic well southeast of New England on Friday. Rip currents will continue to plague parts of the U.S. East Coast, Bermuda, and Atlantic Canada into the weekend, as Erin’s massive circulation –  including tropical-storm-force winds spanning an area 600-700 miles wide – pushes immense volumes of high surf. Erin had already embarked on …

Hurricane Erin made its closest approach to the U.S. at 2 a.m. EDT Thursday, when its center passed about 200 miles (320 km) southeast of the Outer Banks of North Carolina. At the time, tropical storm-force winds of the massive hurricane extended out about 230 miles (370 km) to the northwest of the storm. The U.S. Coast Guard Station at …

Abrupt and potentially irreversible changes in Antarctica driven by climate change could lift global oceans by meters and lead to “catastrophic consequences for generations,” scientists warned Wednesday. More broadly, a state-of-knowledge review by a score of top experts revealed accelerating shifts across the region that are often both a cause and effect of global warming, according to a study published …
