Climate change has a dramatic impact on the global water cycle, say researchers
For Christoph Schär, ETH Zurich's Professor of Climate and Water Cycle, "global warming" is not quite accurate when it comes to describing the driver of climate change.
Coastal ecosystems are a net greenhouse gas sink, new research shows
Many coastlines around the world show high diversity in greenhouse gas sinks and emissions.
Tracking the accelerated melting of glaciers in Greenland
A study reveals widespread mass loss of glaciers and ice caps in Greenland since the 20th century. The meltwater runoff affects North Atlantic ocean circulation, European climate patterns, and Greenlandic fjord water quality and marine ecosystems.
Rapid changes in cryosphere demand urgent, coordinated action
The World Meteorological Organization (WMO) has decided to prioritize the cryosphere due to its significant impacts on sea level rise, water-related hazards, water security, economies, and ecosystems.
Atmospheric rivers linked to melting Greenland ice sheet
Atmospheric rivers — long, concentrated flows of moisture in the sky — are a key factor in the complex conditions accelerating glacial melting over northern Greenland, according to new research from the University of Wisconsin–Madison.
Extreme heat, widespread drought typify European climate in 2022
The Copernicus Climate Change Service releases its annual European State of the Climate (ESOTC) report, detailing the significant climate events of 2022 in Europe and across the globe.
The ice in Antarctica has melted before, says study
Sixty percent of the world's freshwater is bound up in Antarctic ice sheets.
Deep ocean currents around Antarctica headed for collapse, study finds
Antarctic circulation could slow by more than 40 per cent over the next three decades, with significant implications for oceans and the climate.
The Greenland ice sheet is close to a melting point of no return
Once we emit about 1000 gigatons of carbon, much of the massive ice sheet will melt irreversibly, we've emitted 500 gigatons so far.
Satellites reveal speed-up of Antarctic glaciers
Glaciers along the Antarctic peninsula are flowing faster in the summer because of a combination of melting snow and warmer ocean waters, say researchers.
New knowledge about ice sheet movement can shed light on when sea levels will rise
The trawling of thousands of satellite measurements using artificial intelligence has shown researchers from the Geological Survey of Denmark and Greenland and University of Copenhagen that meltwater in tunnels beneath Greenland's ice sheet causes it to change speed, and in some places, accelerate greatly towards the ocean.
Lakes collapse and release meltwater during winter causing inland ice to speed up in Greenland
A team of international researchers has shown for the first time how 18 meltwater lakes in Greenland collapse during winter, which causes the edges of the ice to flow faster.
Acceleration of global sea level rise imminent past 1.8°C planetary warming, says study
A study published in Nature Communications by an international team of scientists shows that an irreversible loss of the West Antarctic and Greenland ice sheets, and a corresponding rapid acceleration of sea level rise, may be imminent if global temperature change cannot be stabilized below 1.8°C, relative to the preindustrial levels.
Parts of Greenland now hotter than at any time in past 1,000 years
A temperature reconstruction from ice cores of the past 1,000 years reveals that today's warming in central-north Greenland is surprisingly pronounced.
How climate change impacts the Indian Ocean dipole, leading to severe droughts and floods
A study led by Brown researchers showed how melting ice water from massive glaciers can ultimately lead to droughts and flooding in East Africa and Indonesia.
Greenland’s glaciers might be melting 100 times as fast as previously thought
A computer model has been created by researchers at the Oden Institute for Computational Engineering and Sciences at The University of Texas at Austin that determines the rate at which Greenland’s glacier fronts are melting.
Eight warmest years on record witness upsurge in climate change impacts
Sea level rise accelerates, European glacier melt shatters records, extreme weather causes devastation.
River longer than the Thames beneath Antarctic ice sheet could affect ice loss
An unexpected river under the Antarctic ice sheet affects the flow and melting of ice, potentially accelerating ice loss as the climate warms.
Temperatures in Europe increase more than twice global average
Temperatures in Europe have increased at more than twice the global average over the past 30 years – the highest of any continent in the world.
Study reveals new insights into how fast-moving glaciers may contribute to sea level rise
Models of sea level rise based on our understanding of how Earth’s ice sheets respond to a warming atmosphere could be incorrect, a new study has found.
