Greenland is melting faster than scientists previously thought -- and will likely lead to faster sea level rise -- thanks to the continued, accelerating warming of the Earth's atmosphere, a new study has found.
An international team of researchers, including Professor Sarah Kang and DoYeon Kim in the School of Urban and Environmental Engineering at South Korea's Ulsan National Institute of Science and Technology (UNIST), has unveiled local drivers of amplified arctic warming.
A new scientific study suggests snoek (Thyrsites atun) can recolonize the marine area of the Beagle Channel and South-Western Atlantic waters, an area in the American continent where this species competed with the hake (Merluccius sp.) to hunt preys in warmer periods. The conclusions open a new scene of potential changes that can affect trophic networks in this marine region due the effect of the rise of ocean temperatures.
Permafrost, is an element of the cryosphere which has not been as much studied as other soils like glaciers or marine ice. Now, for the first time, a review of the state of permafrost on Earth has been carried out thanks to the data analysis of more than 120 drillings distributed around the Arctic and the Antarctica, as well as in mountains and high plains worldwide.
The onset of the most recent ice age about 2.6 million years ago changed where the western Gulf of Mexico gets its supply of sediments. The finding adds new insight into how extreme climate change can directly impact fundamental geological processes and how those impacts play out across different environments.
Researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg have now investigated all glacial areas in South America in more detail than ever before, from the tropical areas to the subpolar regions. Their two major findings are that the highest rate of mass loss is in the Patagonian ice sheet, and that the glaciers in the tropics have lost considerably less mass than previously projected, although this is not the good news which it might appear at first sight.
Antarctica experienced a sixfold increase in yearly ice mass loss between 1979 and 2017, according to a study published today in Proceedings of the National Academy of Sciences. Glaciologists from the University of California, Irvine, NASA's Jet Propulsion Laboratory and the Netherlands' Utrecht University additionally found that the accelerated melting caused global sea levels to rise more than half an inch during that time.
Sea level rise puts coastal areas at the forefront of the impacts of climate change, but new research shows they face other climate-related threats as well. Scientists found that the energy of ocean waves has been growing globally, and they found a direct association between ocean warming and the increase in wave energy.
Variations in the axial tilt of the Earth have significant implications for the rise and fall of the Antarctic Ice Sheet, the miles-deep blanket of ice that locks up huge volumes of water that, if melted, would dramatically elevate sea level and alter the world's coastlines. New research matches the geologic record of Antarctica's ice with the periodic astronomical motions of the Earth.
Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or 'hiatus' in global warming over the past 15 years were unfounded.
