The Atlantic has never gone this late without a hurricane since modern satellite tracking began in 1966. For decades, satellites have watched nearly every swirl of clouds over the Atlantic. In this modern era of storm tracking, the basin has set a record for the latest first hurricane of the season.

Scientists have warned that New Orleans could become an island by 2070, and that relocating its population may be necessary if sea levels rise to higher projections. Louisiana is known for being a particularly low-lying region, which makes it no surprise that New Orleans, a city of around 360,000 people, is vulnerable to sea-level rise. The wetlands that surround the city act as a buffer against

Learn how satellite radar captured the moment a Manhattan-sized ice island broke away from Greenland’s Petermann Glacier and why scientists are keeping a close watch.

Researchers warn that U.S. data centers could devour vast amounts of energy and water unless stronger guardrails shape the industry’s growth. When Cornell University systems engineer Fengqi You started modeling the environmental footprint of data centers three years ago, the A.I. boom was just beginning. Even then, You and his colleagues noticed something missing from the conversation
