Rapidly warming Artic could cause spread of nuclear waste and undiscovered viruses
Rapidly thawing Arctic permafrost has the potential to release radioactive waste from cold war nuclear submarines and reactors, antibiotic resistant bacteria and potentially undiscovered viruses, an Aberystwyth University researcher has jointly found.
Satellites reveal Arctic rivers are changing faster than we thought
New analysis integrating data from satellites, river gauges and hydrologic models reveals Arctic rivers are discharging much more water than previously thought
Runoff, sediment flux in High Mountain Asia could limit food, energy for millions
Average temperatures in high altitude areas have risen twice as fast as the global average, causing more river runoff and sediment flux, and the trend could get worse, scientists find.
Satellite monitoring of Greenland ice melting highlights global flood risk
Global warming has caused extreme ice melting events in Greenland to become more frequent and intense over the past 40 years, raising sea levels and flood risk worldwide, finds new research involving UCL academics.
WMO: Extreme weather events will be the new norm
WMO's new report finds that the past 7 years set to be the warmest on record, sea level rise at new high.
Greenland’s groundwater changes with thinning ice sheet
For more than a decade, a team of University of Montana researchers and students have studied the dynamics of the Greenland Ice Sheet as it responds to a warming climate.
Wake up to the looming water crisis, report warns
Water-related hazards like floods and droughts are increasing because of climate change.
Jet stream changes could amplify weather extremes by 2060s
Drilling deep into the Greenland ice sheet, researchers reconstructed the jet stream's tumultuous past and found that climate-caused disruptions are likely to have drastic weather-related consequences for societies on both sides of the Atlantic.
Global warming threatens the existence of an Arctic oasis
The most significant Arctic oasis is susceptible to climate change – researchers say that global warming is threatening the region’s ecosystem, and predict that the oasis will cease to exist.
Rise and fall of water blisters offers glimpse beneath Greenland’s thick ice sheet
Water “blisters” trapped beneath the thick interior of Greenland’s ice sheet could provide critical insight into the hydrological network coursing deep below Earth’s second largest body of ice — and how it might be destabilized by climate change, according to a new study.
Increased snowfall will offset sea level rise from melting Antarctic ice sheet, new study finds
A new study predicts that any sea level rise in the world’s most southern continent will be countered by an increase in snowfall, associated with a warmer Polar atmosphere.
Some past sea levels may not have been as high as thought, study says
One of the current mysteries of climate science surrounds the widely accepted evidence that during the planet’s most recent past natural warm period, about 128,000 to 117,000 years ago, global sea levels peaked as high as 6 to 9 meters (20 or 30 feet) higher than today.
Understanding past climate change ‘tipping points’ can help us prepare for the future
Of all the creatures on Earth, humans manipulate their environments the most.
Earth’s vital signs worsen amid business-as-usual mindset on climate change
Twenty months after declaring a climate emergency and establishing a set of vital signs for the Earth, a coalition headed by two Oregon State University researchers says the updated vital signs “largely reflect the consequences of unrelenting business as usual.”
Reducing the melting of the Greenland ice sheet using solar geoengineering?
Injecting sulphur into the stratosphere to reduce solar radiation and stop the Greenland ice sheet from melting.
NASA space lasers map meltwater lakes in Antarctica with striking precision
From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years.
Last ice-covered parts of summertime Arctic Ocean vulnerable to climate change
In a rapidly changing Arctic, one area might serve as a refuge – a place that could continue to harbor ice-dependent species when conditions in nearby areas become inhospitable.
Aging snow is making greenland darker, warmer
Frequent high-pressure weather systems centered over greenland push away fresh snowfall, leaving larger, older snow grains on the surface that make the ice sheet less reflective.
‘Doomsday Glacier’ may be more stable than initially feared
Study sheds light on the future of the massive Thwaites Glacier.
CryoSat reveals ice loss from glaciers in Alaska and Asia
As our climate warms, ice melting from glaciers around the world is one of main causes of sea-level rise.
