Credit: CC0 Public Domain Scientists from the National Oceanography Centre (NOC) have discovered that increased meltwater in the North Atlantic can trigger a chain of events leading to hotter and drier European summers. The paper, which is published in the open access journal Weather and Climate Dynamics, suggests that European summer weather is predictable…

Meltwater, which first made its name around media monitoring and then got active in business intelligence using AI and big data analytics techniques, is picking up a new investor. Verdane, a Norwegian private equity firm that earlier this year closed a $1 billion+ fund to make investments in scaling tech companies, is taking an 11% stake in Meltwater, at a company valuation of €542 million ($592 million), valuing the stake at around $65 million. But that’s not the only deal that is going down with this transaction.…

Credit: NIGPAS Subglacial discharge from the Antarctic Ice Sheet (AIS) likely played a crucial role in the loss of ice sheet and the subsequent rise in sea level during the last deglaciation. However, no direct proxy is currently available to document subglacial discharge from the AIS, which leaves significant gaps in our understanding of the complex interactions between subglacial…

Researchers have found new insights into how water from melting ice could have helped in the formation of ravine-like channels that cut down the sides of impact craters on Mars.Called Martian gullies, which look similar to gullies that form on Earth in the Dry Valleys of Antarctica, are caused by water erosion from melting glaciers. The researchers, published their paper in Science, found that when Mars tilts on its axis to 35 degrees, the atmosphere becomes dense enough for brief episodes of melting to occur at gully…

High rates of meltwater discharge combined with a thick and gently sloping ice sheet in Western Greenland gives rise to monster holes like this moulin. Credit: Alun Hubbard I'm striding along the steep bank of a raging white-water torrent, and even though the canyon is only about the width of a highway, the river's flow is greater than that of London's Thames. The deafening roar and rumble of the cascading water is…

Off the coast of Antarctica, trillions of tons of cold salty water sink to great depths. As the water sinks, it drives the deepest flows of the "overturning" circulation – a network of strong currents spanning the world's oceans.The overturning circulation carries heat, carbon, oxygen, and nutrients around the globe, and fundamentally influences climate, sea level, and the productivity of marine ecosystems.But there are worrying signs these currents are slowing down. They may even collapse.If this happens, it would…

Data collection in the Arctic is not simple. Ny- Ålesund, a small town in Spitsbergen, Svalbard, provides a base in the Arctics for research. However, to get to the location of the test site can still take many hours of hiking in exceedingly difficult terrain. Credit: Dr Andreas Alexander Norwegian and Estonian researchers have developed a method to map hidden meltwater paths in glaciers. Having a better understanding of how…

Greenland.

The new knowledge is essential for understanding how climate change influences the flow of ice masses in the Arctic. …

All of the glaciers in Yosemite National Park, Italy’s Dolomite mountains, the continent of Africa, and thousands of other individual ice giants are set to disappear over the next 30 years, according to a new report from the United Nations.01:25Randall Park's Favorite SuperheroesMonday 5:02PMAnd, at this point in climate change, the UN says that we’re powerless to stop that loss. Under each and every climate projection model that the researchers assessed, a full one-third of glaciers located within UNESCO World Heritage…
