Polar bears in Western Hudson Bay have seen their population nearly halved over the last several decades, largely due to dwindling sea ice and limited hunting opportunities, according to a study using a novel bioenergetic model. https://t.co/sIYGQKLG1b

RT @esa_earthcare: Check out EarthCARE’s incredible images of winter in the stratosphere! 🤩

Rare, mysterious and beautiful polar stratospheric clouds have dazzled sky-gazers this winter. Thanks to EarthCARE's newly released Level 1 data, we can observe them in great detail from space.

Thanks to @TROPOS_de @ECMWF @TelespazioUK @KNMI and the EarthCARE DISC for the exciting data and insights!

RT @esa_earthcare: In conditions of extremely cold temperatures, below -78°C, polar stratospheric clouds (PSCs) can form at altitudes of around 20-30 km. These rare clouds are iridescent, appearing rainbow-like in the sky. They are often known as acid clouds because they are commonly formed from a mixture of water and nitric acid.

PSCs were observed by EarthCARE on 13 January 2025 as it travelled over northern Europe, from Ukraine to northern Greenland. A long band of these clouds stretched approximately 3,000 km from Latvia, over Finland, Sweden, and Norway, to Greenland at heights of between 20 and 30 km.

In the Arctic, PSCs mostly consist of tiny acid droplets, known as Type I, but EarthCARE’s Atmospheric Lidar (ATLID), which uses a laser to detect clouds and aerosols, also detected those consisting of ice crystals, known as Type II.

Type II PSCs are very rare in the Arctic due to the very low temperatures required for their formation, and much more commonly form in Antarctica where temperatures frequently dip below -88°C.

According to the European Centre for Medium-Range Weather Forecasts (ECMWF) weather model, the temperatures in these clouds reached as low as -97.3°C.
