An anonymous reader quotes a report from The Guardian: Last year’s summer was so warm that it helped trigger the loss of 600 billion tons of ice from Greenland — enough to raise global sea levels by 2.2mm in just two months, new research has found. Unlike the retreat of sea ice, the loss of land-based glaciers directly causes the seas…

World’s highest mammal discovered at the top of a Mars-like volcano
The highest dwelling mammal – a mouse – has been discovered at 6700 metres above sea level, where conditions are so harsh they have been compared to Mars Source: https://www.newscientist.com/article/2237997-worlds-highest-mammal-discovered-at-the-top-of-a-mars-like-volcano/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Growing stem cells for deep space exploration
Earth’s magnetosphere protects us from the most harmful cosmic rays that bombard our planet but beyond this natural shield, astronauts are subjected to radiation that is a hundred times more than at sea level. Source: https://phys.org/news/2020-03-stem-cells-deep-space-exploration.html…
What is the gegenschein?
The sun’s counterglow – or gegenschein – is kind of a stargazers’ legend. What is it, and how can you see it? Erwin Matys and Karoline Mrazek of Project Nightflight explain. Source: https://earthsky.org/space/definition-what-is-the-gegenschein…
Melting Glaciers: Effects on the Environment, Humans, and Biodiversity
Recently, the temperature in the Arctic appears to have hit a new continental high, close to 70 degrees. That’s leading to continued melting of glaciers in the Arctic and around the world. But how will that impact the world’s ecosystems? Dr. David Hik is an Associate Dean of the Faculty of Science as well as […]

Himalayan glacier shows evidence of start of Industrial Revolution
Human beings altered one of the highest peaks in the Himalayas hundreds of years before a person ever set foot there, new research has found. Source: https://earthsky.org/earth/himalayan-glacier-evidence-start-industrial-revolution…
Antarctic ice melt could push sea levels to rise 1.5 metres by 2100
If carbon emissions go largely unchecked until 2100, Antarctic ice melt could result in three times as much sea level rise as we saw from all sources in the 20th century Source: https://www.newscientist.com/article/2233619-antarctic-ice-melt-could-push-sea-levels-to-rise-1-5-metres-by-2100/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Ötzi the Iceman’s final days
Scientists have identified ancient mosses in, on and around the 5,300-year-old glacier mummy that add to the story of the final 48 hours before his murder. Source: https://earthsky.org/earth/otzi-the-iceman-mummy-ancient-mosses…
Warm water measured below Antarctic glacier
The warm water found flowing under Thwaites Glacier in western Antarctica helps explain its rapid melting. Thwaites is part of what’s described the “weak underbelly” of the West Antarctic Ice Sheet. Its melting has implications for sea-level rise around the world. Source: https://earthsky.org/earth/warm-water-measured-below-thwaites-glacier-antarctica…
The seabed is sinking under the weight of water from melting ice caps
Water flowing into the oceans from Greenland and Antarctica is pushing the seabed down 0.1 millimetres a year, but don’t get your hopes up – it won’t stop sea level rise Source: https://www.newscientist.com/article/2231896-the-seabed-is-sinking-under-the-weight-of-water-from-melting-ice-caps/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
