The impact of melting ice in Greenland and Antarctica on the world’s oceans is well documented. But the largest contributors to sea level rise in the 20th century were melting ice caps and glaciers located in seven other regions: Alaska, the Canadian Arctic Archipelago, the Southern Andes, High Mountain Asia, the Russian Arctic, Iceland and the Norwegian archipelago Svalbard. The five Arctic regions accounted for the greatest share of ice loss. ![]() A small glacier in the Arctic region of Norwegian archipelago Svalbard, as photographed by NASA’s Airborne Tropical Tropopause Experiment (ATTREX). This is one of the seven regions where ice loss is accelerating, causing the depletion of freshwater resources. (NASA/John Sonntag) «Read the rest of this article» Sections: Technology | No Comments
NASA study shows Denman Glacier vulnerable to Seawater Intrusion
Until recently, researchers believed East Antarctica was more stable than West Antarctica because it wasn’t losing as much ice compared to the glacial melt observed in the western part of the continent. ![]() This photograph shows ripples in the surface of Denman Glacier in East Antarctica that throw shadows against the ice. The glacier is melting at a faster rate now than it was from 2003 to 2008. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA Satellite Data reveals Climate Change effect on Fires
Since 1880, the world has warmed by 1.9 degrees Fahrenheit, with the five warmest years on record occurring in the last five years. Since the 1980s, the wildfire season has lengthened across a quarter of the world’s vegetated surface, and in some places like California, fire has become nearly a year-round risk. ![]() Fires are a natural part of the ecosystem in North American forests. However, their size and intensity is shaped by climate. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA study shows Thwaites Glacier in West Antarctica is disintegratingNASA Jet Propulsion Laboratory
The findings highlight the need for detailed observations of Antarctic glaciers’ undersides in calculating how fast global sea levels will rise in response to climate change. Researchers expected to find some gaps between ice and bedrock at Thwaites’ bottom where ocean water could flow in and melt the glacier from below. «Read the rest of this article» Sections: Technology | No Comments
NASA’s new simulator allows anyone to experiment with Sea Level ScienceWritten by Pat Brennan
Computer models are critical tools for understanding the future of a changing planet, including melting ice, rising seas and shifting precipitation patterns. But typically, these mathematical representations — long chains of computer code giving rise to images of dynamic change — are accessible mainly to scientists. «Read the rest of this article» Sections: Technology | No Comments
NASA reports newest Greenland Maps Show more Glaciers at Risk of Accelerated MeltingWritten by Carol Rasmussen
Researchers at the University of California at Irvine (UCI), NASA and 30 other institutions have published the most comprehensive, accurate and high-resolution relief maps ever made of Greenland’s bedrock and coastal seafloor. Among the many data sources incorporated into the new maps are data from NASA’s Ocean Melting Greenland (OMG) campaign. ![]() Left: Greenland topography color coded color-coded from 4,900 feet (1,500 meters) below sea level (dark blue) to 4,900 feet above (brown). Right: Regions below sea level connected to the ocean; darker colors are deeper. The thin white line shows the current extent of the ice sheet.

NASA Study reveals Antarctic Glacier’s Ice Loss May Not Progress as Quickly as ThoughtWritten by Carol Rasmussen
The new study, published in the journal Geophysical Research Letters, finds that numerical models used in previous studies have overestimated how rapidly ocean water is able to melt the glacier from below, leading them to overestimate the glacier’s total ice loss over the next 50 years by about 7 percent. «Read the rest of this article» Sections: Technology | No Comments
NASA reports new study reveals Intense Melting beneath West Antarctic GlaciersWritten by Alan Buis
The results highlight how the interaction between ocean conditions and the bedrock beneath a glacier can influence the glacier’s evolution, with implications for understanding future ice loss from Antarctica and global sea level rise. ![]() A view from Operation IceBridge’s aircraft of Crosson Ice Shelf, foreground.

NASA Satellite data reveals Earth’s land masses are absorbing Water and slowing Sea Level riseWritten by Alan Buis
A new study by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, and the University of California, Irvine, shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth’s continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent. ![]() Earth’s land masses have stored increasing amounts of water in the last decade, slowing the pace of sea level rise.

NASA studies how 2015 El Niño effects the World’s ClimateWritten by Alan Buis
New results presented Tuesday, December 15th, at the American Geophysical Union meeting in San Francisco show that atmospheric rivers, significant sources of rainfall, tend to intensify during El Niño events, and this year’s strong El Niño likely will bring more precipitation to California and some relief for the drought. «Read the rest of this article» Sections: Technology | No Comments
