Icebergs push back, study finds
New study: Slushy iceberg aggregates control calving timing on Greenland’s Jakobshavn Isbræ
Researchers find Greenland glacial meltwaters rich in mercury
New research shows that concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding that is raising questions about the effects of glacial melting in an area that is a major exporter of seafood.
Arctic sea ice succumbs to Atlantification
With alarm bells ringing about the rapid demise of sea ice in the Arctic Ocean, satellite data have revealed how the intrusion of warmer Atlantic waters is reducing ice regrowth in the winter.
Stanford researchers use airborne radar to detect groundwater beneath Greenland glacier
Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. If applicable to other glaciers and ice sheets, the technique could allow for more accurate predictions of future sea-level rise.
Fibre-optics used to take the temperature of Greenland Ice Sheet
Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet.
Stanford researchers reveal the long-term impacts of extreme melt on Greenland Ice Sheet
Researchers have deciphered a trove of data that shows one season of extreme melt can reduce the Greenland Ice Sheet’s capacity to store future meltwater – and increase the likelihood of future melt raising sea levels.
Melting ice sheets caused sea levels to rise up to 18 metres
Research led by our geography department has found that previous ice loss events caused sea-levels to rise around 3.6 metres per century, offering vital clues as to what lies ahead should climate change continue.
Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter
Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for the speed at which the world’s second-largest ice sheet flows to the ocean.
World Meteorological Day celebrates the ocean, our climate and weather
The ocean drives the world’s weather and climate and anchors the global economy and food security.
The Arctic Ocean was covered by a shelf ice and filled with freshwater
Scientists from Alfred Wegener Institute: “We need to have a fresh look at the role of the Arctic Ocean.”
Antarctica’s ice melt isn’t consistent, new analysis shows
Antarctic ice is melting, contributing massive amounts of water to the world's seas and causing them to rise—but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years' worth of satellite data indicates.
Sea level will rise faster than previously thought
There are two main elements to observe when assessing sea level rise.
Increasing ocean temperature threatens Greenland’s ice sheet
UCI and NASA JPL scientists study impact of warm, salty water beneath glaciers
Climate change in antiquity: mass emigration due to water scarcity
The absence of monsoon rains at the source of the Nile was the cause of migrations and the demise of entire settlements in the late Roman province of Egypt.
Global ice loss increases at record rate
he rate at which ice is disappearing across the planet is speeding up, according to new research.
To predict the future of polar ice, environmental scientists are looking to the past
Over the past century, global sea level has been rising at an increasingly rapid pace.
Ice sheet uncertainties could mean sea level will rise more than predicted
Sea level could rise higher than current estimates by 2100 if climate change is unchallenged, according to a new assessment.
The melting of the Greenland ice sheet could lead to a sea level rise of 18 cm in 2100
A new study, headed by researchers from the Universities of Liège and Oslo, applying the latest climate models, of which the MAR predicts a 60% greater melting of the Greenland ice sheet than previously predicted.
2020 on track to be one of three warmest years on record
Climate change continued its relentless march in 2020, which is on track to be one of the three warmest years on record.
Study: Greenland is on track to lose ice faster than in any century over the last 12,000 years
The research places the ice sheet’s modern decline in historical context, providing a robust look at how this century’s losses could starkly outpace prior changes.
