Greenland

In a Finnish outcrop nestled between some of Northern Europe's oldest mountains, researchers have found traces of a previously hidden part of Earth's crust that points more than 3 billion years back in time.

The study helps us understand the origin of continents and why Earth…

Petermann Glacier drains about 4 percent of the Greenland Ice Sheet as it moves inexorably toward the Arctic Ocean. A new observation and modeling study shows that the glacier is more vulnerable than previously thought to the intrusion of warm ocean water on its underside, leading to accelerated melting and boosting the potential severity of future sea level rise. Credit: Eric Rignot / UCIUC Irvine researchers suggest we may be underestimating the severity of sea level rise.Researchers at the University of California,…

Ice melting has become an ever-pressing concern in recent decades as climate change has brought evocative images of lone polar bears floating on unsustainable small blocks of sea ice. Yet, the consequences are far-reaching in terms of freshening of seawater altering marine ecosystems, sea level rise…

In a crazy demonstration of just how little Greenland cares about following the laws of physics, the large island is rising out of the sea. The rise, researchers say, is fueled by Greenland’s ongoing ice loss, which continues to melt as global temperatures rise.For those who haven’t kept up with the ongoing climate change issues, the ice and glaciers around Greenland are melting, acting as a major addition to the rising sea levels we’re seeing around the world. But, even with the sea levels rising, Greenland…

In a mocking fluke of physics, Greenland – one of the main sources of meltwater flooding Earth's shores – is actually rising faster than the rising oceans.The elevating bedrock is gradually birthing new land in Greenland's sea including small islands and skerries, like Uunartoq Qeqertaq. Translating as 'warming island', this new 13 kilometer (8 mile) long landmass off the east coast of Greenland was officially recognized and added to Greenland's maps in 2005."The land uplift we observe in Greenland these years cannot be…

This transformation has increased vegetation, altered landscapes, and exacerbated climate change effects, highlighting the critical need for climate action.An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland’s ice sheet and glaciers have melted…

"On average and since 2000, dry landscapes of the ice-free part of Greenland have consumed more than 65,000 tons of methane annually from the atmosphere, while 9,000 tons…
