Glaciers around the world have reduced more than 5 percent since 2000, as well as the widest assessment. This fast melting rate has accelerated more than a third decade while climate change progresses.
“Any level to warm up for glaciers,” he says Noel Gourmelen From the University of Edinburgh, the United Kingdom. “They are a barometer for climate change.”
New numbers come from the global consortium of the study of hundreds of Glacian mass balance internparison. The group managed to reduce the uncertainty of the 200,000 and glaciers of the planet, using the standard procedure for evaluating different size change measures. This includes gravity and elevation measurements from 20 satellites and based measurements.
Between 2000 and 2011, the glaciers were found on average about 231 million tonnes of ice a year. This year every year melting this year, acceleration of more than one third year. In 2023 he saw a loss of mass of 548 trillion.
These numbers match previous estimates. But this comprehensive look “gives greater confidence about the change we see in glaciers,” says Gourmelen who is part of the consortium. “And there is a clear acceleration.”
Completely, around 7 trillion rays of glacial level has risen almost 2 centimeters after almost 2 centimeters, in terms of sea level rise, melts behind the expansion of water To warm the oceans.
“This is a consistent story of the glacial change,” he says Tyler Sutterley Seattle at Washington University. “Immorients of time Losing these ice icons to lose these ice icons”.
The Alps glaciers have lost more than any other region, 2000. since the year, almost 40% reduction. In the Middle East, New Zealand and West of North America, glaciers have also seen reductions of more than 20 percent. According to future emissions, world glaciers are projected to lose about the quarter and half of the century.
