The first complete picture of Arctic sea ice freeze-thaw cycle highlights sea ice response to climate change

Years of research show that climate change signals are amplified in the Arctic, and that sea ice in this region is sensitive to increases in Arctic warming. Sea ice greatly modifies the exchanges of heat, momentum and mass ...

Report: Much of the world was drier than usual last year despite La NiƱa

The World Meteorological Organization has published its first State of Global Water Resources report in order to assess the effects of climate, environmental and societal change on the Earth's water resources. The aim of ...

Working with mountain communities could help water systems adapt to climate

Nearly two billion people globally rely on mountain water for drinking and irrigation, but this water source is under threat due to global heating. Mountainous regions are particularly impacted by the effects of the climate ...

Newly discovered optical effect allows the IceCube Neutrino Observatory to deduce ice crystal properties

Every second, 100 trillion neutrinos pass through the human body. These tiny, almost massless particles travel tremendous distances through space while carrying information about their sources and are created by some of the ...

Seasonal change in Antarctic ice sheet movement observed for first time

Some estimates of Antarctica's total contribution to sea-level rise may be over- or underestimated, after researchers detected a previously unknown source of ice loss variability.

Marine ice sheets were decisive in acceleration of global warming during the last deglaciation

The intensity and rate of melt during the penultimate ice melting was much higher than previously thought, according to a study published in the journal Nature Communications. According to conclusions of the study, in this ...

Refreezing Earth's poles feasible and cheap, new study finds

The poles are warming several times faster than the global average, causing record smashing heatwaves that were reported earlier this year in both the Arctic and Antarctic. Melting ice and collapsing glaciers at high latitudes ...

Glaciers flowed on ancient Mars, but slowly

The weight and grinding movement of glaciers has carved distinctive valleys and fjords into Earth's surface. Because Mars lacks similar landscapes, researchers believed ancient ice masses on the Red Planet must have been ...

Study: Already shrunk by half, Swiss glaciers melting faster

Switzerland's 1,400 glaciers have lost more than half their total volume since the early 1930s, a new study has found, and researchers say the ice retreat is accelerating at a time of growing concerns about climate change.

A historical perspective on glacial retreat

Researchers at ETH Zurich and WSL have for the first time reconstructed the extent of Switzerland's glacier ice loss in the 20th century. For this purpose, the researchers used historical imagery and conclude that the country's ...
