Researchers at the Swedish Centre for Palaeogenetics have analyzed DNA from an extinct woolly rhinoceros found in the stomach of a frozen wolf pup. The discovery, the first of its kind from the Ice Age, provides new clues about the species' extinction. The analysis suggests climate change likely caused the rhinoceros's disappearance rather than human hunting.
A new study reveals that shifts in Antarctic Bottom Water circulation around 18,000 to 10,000 years ago drove the release of stored carbon into the atmosphere, contributing to the warming at the end of the last Ice Age. Researchers analyzed sediment cores to trace these changes, highlighting the Southern Ocean's role in the global carbon cycle. The findings suggest implications for modern Antarctic ice melt and climate projections.

Fresh imagery from ESA's Mars Express orbiter has exposed signs of a past ice age in the Coloe Fossae region of Mars. These features include glacial-like patterns in valleys and craters, hinting at climate shifts that spread ice far from the poles. The findings suggest this icy period ended as recently as 500,000 years ago.
