A new study from UNC-Chapel Hill reveals that repetitive flooding in North Carolina is far more common and more widespread than previously recognized, with over 20,000 buildings flooding multiple times between 1996 and 2020.

Scientists from the Marine Biological Association and the University of Plymouth have revisited turn-of-the-century forecasts about the many and varied threats they thought were likely to face the world’s shorelines in 2025. Their new study highlights that many of their forecasts were correct, either in whole or in part, while others haven’t had the impacts that were envisaged at the time. They have also charted some of the other threats to have emerged and/or grown in significance since their original work, with notable examples including global plastic pollution, ocean acidification, extreme storms and weather, and light and noise pollution.

A new study solves a long-standing climate mystery: Why don't the records of oxygen isotopes in cave formations like stalagmites—known as speleothems—from central southern China reflect the well-known 100,000-year cycles of ice ages seen in other global climate records? These speleothem records have long been considered a key indicator of the strength of the Asian summer monsoon, so their failure to show these major climate shifts has puzzled scientists for decades.

Researchers at Eötvös Loránd University are generating realistic drone footage of landscapes from even hundreds of years ago with the help of artificial intelligence. With their method, presented in the journal Land, the authors aim to introduce a new tool that helps to better understand the original functioning of a landscape and can support strategic decisions about current land use — for example, implementing water retention solutions in often drought-stricken areas such as the Hungarian Great Plain.

The remains of landscapes thought to have formed when ancient rivers flowed across East Antarctica have been discovered – and could help predictions of future loss from the ice sheet.
