Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research led by The University of Texas at Austin has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks.
A new study by The University of Texas at Austin has demonstrated a possible link between life on Earth and the movement of continents. The findings show that sediment, which is often comprised from pieces of dead organisms, could play a key role in determining the speed of continental drift.
Christopher A. Williams, associate professor in Clark University's Graduate School of Geography and postdoctoral research scientist Huan Gu, Ph.D., worked with The Nature Conservancy and close to two dozen institutional partners on 'Natural Climate Solutions for the United States,' published today in Science Advances. The new study highlights natural solutions in the United States that offer the most promise to help limit warming to 1.5 degrees Centigrade (approximately 3 degrees Fahrenheit).
Large quantities dust from the deserts of the Middle East can settle on the Tibetan Plateau, darkening the region's snowpack and accelerating snow melt. A new atmospheric modeling study suggests that, in some years, heavy springtime dust deposition can set off a series of feedbacks that intensify the Indian summer monsoon. The findings could explain a correlation between Tibetan snowpack and the Indian monsoon first observed by British meteorologist Henry Blanford in 1884.
A 31-kilometer-wide impact crater underneath about a kilometer of the Hiawatha Glacier's ice is the first of its kind to be discovered in northwest Greenland, scientists report.
Rising global sea levels may actually be beneficial to the long-term future of coral reef islands, such as the Maldives, according to new research published in Geophysical Research Letters. Low-lying coral reef islands are typically less than three metres above sea level, making them highly vulnerable to rising sea levels associated with climate change. However, research has found new evidence that the Maldives -- the world's lowest country -- formed when sea levels were higher than they are today.
Researchers led by Arizona State University have completed some of the most sophisticated modeling of the effects of climate change and urban centers in the US, and are finding that some of today's proposed solutions will provide only a fraction of relief from the projected heat.
A study by scientist Dirk Scherler of the German Research Centre for Geosciences GFZ and two colleagues from Switzerland shows a possibility to detect the extent of debris on mountain glaciers globally and automatically via satellite monitoring. The scientists used the cloud computing platform Google Earth Engine for their study.
Stone tools that were discovered and examined by a group of international experts showed for the first time that various communities that lived during the Middle Stone Age period were widely connected and shared ideas around tool design.
Geographers from the National University of Singapore have found that coastal vegetation such as mangroves, seagrasses, and salt marshes may be the most effective habitats to mitigate carbon emissions.
