Understanding climate tipping points

As the planet warms, many parts of the Earth system are undergoing large-scale changes. Ice sheets are shrinking, sea levels are rising and coral reefs are dying off.

All regions experienced water extremes in 2021: UN

All regions of the world saw water extremes last year—both floods and droughts—and billions of people had insufficient freshwater, the United Nations said on Tuesday.

Vegetation regulates energy exchange in the Arctic

Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers ...

Listening to the song of melting glaciers

This is it, we have reached the bottom of the glacier. It is 327m under our feet. After drilling into the ice for six hours, our hot-water jet blasts into the sediment. The hose that connects it to the surface stops rolling ...

Patagonia's coast offers cool refuge for giant kelp

Giant kelp forests around the world have struggled to stay healthy in recent decades, with some vanishing altogether. But along Patagonia's rugged southwestern coast, giant kelp are thriving, showing remarkable stability ...

Researchers model 'red snow' algal blooming events

Red snow is a unique phenomenon caused by blooms of red algae that live on the surface of snow. Now, researchers from Japan have developed a model to predict the occurrence of red snow events. In a recent study published ...

Melting glasses from unmeltable compounds

Glasses are an indispensable part of everyday life. One of the most important reasons for this is that glass objects can be manufactured almost universally and inexpensively in a wide variety of shapes and sizes using their ...

Astronomers find formula for subsurface oceans in exomoons

So far, the search for extraterrestrial life has focused on planets at a distance from their star where liquid water is possible on the surface. But within our Solar System, most of the liquid water seems to be outside this ...
