Last January, a study in Nature Climate Change showed the world's glaciers are the smallest they've been in human history, revealing radiocarbon material that hasn't been exposed for 40,000 years. Now, new research published in Nature quantifies how much the world's lost glaciers have contributed to rising sea levels. From …
The Greenland ice sheet presently accounts for ~70% of global ice sheet mass loss. Because this mass loss is associated with sea-level rise at a rate of 0.7 mm/year, the development of improved monitoring techniques to observe ongoing changes in ice sheet mass balance is of paramount concern. Spaceborne mass …
Despite rapid melting in the coastal regions of the Greenland Ice Sheet, a significant area (~40%) of the ice sheet rarely experiences surface melting. In these regions, the controls on annual accumulation are poorly constrained owing to surface conditions (for example, surface clouds, blowing snow, and surface inversions), which render …
To study climate change, India is conducting a programme to monitor one of the major fjords on the Svalbard archipelago in the Arctic region, the government today said. In a written response to a question in the Lok Sabha, YS Chowdary, Minister of State for Earth Sciences, said the ministry …
Climate change and extreme weather - including unusually wet summers in the UK - linked to high pressure weather systems over Greenland Study finds increase in atmospheric high pressure systems since 1980s throughout all seasons High pressure weather systems drag unusually warm air over Greenland's Ice Sheet Greenland is one …
New scientific studies show that the North Pole is gradually shifting towards the UK, as global warming is changing the way the Earth turns on its axis. Experts and scientists now believe the North Pole's movement is being caused by a shift in the distribution of water across the planet …
Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. 'Blocking-high' pressure systems spawn most of the warming that melts Greenland surface ice Rutgers study says. These dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, …
NASA is sending scientists around the world this year - from the edge of the Greenland ice sheet to the coral reefs of the South Pacific - to delve into challenging questions about how our planet is changing and what impact humans are having on it. While Earth science field …
We use numerical climate simulations, paleoclimate data, and modern observations to study the effect of growing ice melt from Antarctica and Greenland. Meltwater tends to stabilize the ocean column, inducing amplifying feedbacks that increase subsurface ocean warming and ice shelf melting. Original Source
Rising sea levels driven by climate change could upend the lives of more than 13 million Americans by the end of the century, according to a study released on Monday. If global warming lifts oceans 1.8 metres (six feet) by 2100, as some scientists forecast in worst-case scenarios, 13.1 million …
A new scientific study released Thursday has delivered yet another burst of bad news about Greenland — the vast northern ice sheet that contains 20 feet of potential sea level rise. The ice sheet is “darkening,” or losing its ability to reflect both visible and invisible radiation, as it melts …
As sea levels rise, threatening cities from New York to Shanghai, the economic damage will increase even faster, scientists said on Monday. Extreme floods whipped up by storms will become ever more costly for cities as ocean levels edge up around the world's coasts in coming decades, they wrote in …
The contribution of the Greenland and West Antarctic ice sheets to sea level has increased in recent decades, largely owing to the thinning and retreat of outlet glaciers and ice streams. This dynamic loss is a serious concern, with some modelling studies suggesting that the collapse of a major ice …
Clouds are raising the temperature of the Greenland ice Sheet and accounting for as much as 30 percent of the ice sheet melt, researchers say. The rapidly melting Greenland ice sheet is likely driving almost a third of global sea level rise, the study pointed out. "With climate change at …
Researchers say that the Greenland ice sheet is quickly losing the ability to hinder sea level rise despite being known as a sponge for glacier meltwater. The study, published in the journal Nature, projects that sea level rise due to meltwater runoff is likely higher than what was previously predicted. …
The Greenland Ice Sheet has lost about 9,013 gigatonnes of water ice from 1900 to 2010 – and it’s dropping mass today at an increasing rate, an international team of scientists say. From 2003 to 2010, the ice sheet lost mass at a rate more than twice the rate during …
The response of the Greenland Ice Sheet (GIS) to changes in temperature during the twentieth century remains contentious1, largely owing to difficulties in estimating the spatial and temporal distribution of ice mass changes before 1992, when Greenland-wide observations first became available2. The only previous estimates of change during the twentieth …
Greenland's glaciers are retreating quickly, and a new study shows in historical terms just how quickly: over the past century, at least twice as fast as any other time in the past 9,500 years. The study also provides new evidence for just how sensitive glaciers are to temperature, showing that …
Greenland's glaciers may be retreating far more quickly than expected. Scientists have taken a closer look at their historical retreat and have found that over the past century, they've melted at least twice as fast as any other time in the past 9,500 years. In order to track how glaciers …
Small glaciers and ice caps respond rapidly to climate variations, and records of their past extent provide information on the natural envelope of past climate variability. Millennial-scale trends in Holocene glacier size are well documented and correspond with changes in Northern Hemisphere summer insolation. However, there is only sparse and …
Whether or not an increase in meltwater will make ice sheets move more quickly has been contentious, because water lubricates the ice–rock interface and speeds up the ice, but also stimulates the development of efficient drainage; now, a long-term and large-area study of a land-terminating margin of the Greenland Ice …
