A new study of the marine invertebrates living in the seas around Antarctica reveals there will be more 'losers' than 'winners' over the next century as the Antarctic seafloor warms. The results are published in the journal Nature Climate Change this week.
Dark water formed an eddy around Steve Eisenhauer's boots as they sank into the muck at the base of a 90-foot black gum tree so old, its roots were deep in this ground when the Pilgrims landed.
For centuries, marine species have moved around either by hitching ride on the hulls of ships or as stowaways in ballast water. In many instances, species have been deliberately introduced for aquaculture or other commercial purposes.
Permafrost is ground that stays frozen year round; the permafrost in interior Alaska also has massive wedges of actual ice locked within the frozen ground. When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born. At first glance, Big Trail looks like any lake. But look closer and there's something disturbing the surface: bubbles.
Morris Animal Foundation-funded researchers uncovered several key factors contributing to a die-off of South American fur seal pups, including mites, pneumonia and sea surface temperature. The findings, published in the Journal of Wildlife Diseases, help scientists better understand the link between environmental factors and health.
Two extreme weather events in 2006 and 2013 caused mass starvation among the reindeer herds, and researchers for the first time have linked these extreme weather events in the coastal mainland in northwest Russia with sea ice loss in the adjoining Barents and Kara seas.
New research led by U of T Mississauga geographer Igor Lehnherr provides startling evidence that remote areas in Canada's Arctic region—once thought to be beyond the reach of human impact—are responding rapidly to warming global temperatures.
Researchers from the Universities of Bremen and Innsbruck have shown in a recent study that the further melting of glaciers cannot be prevented in the current century—even if all emissions were curtailed. However, due to the slow reaction of glaciers to climate change, human activity will have a massive impact beyond the 21st century. In the long run, 500 meters by car with a mid-range vehicle will cost one kilogram of glacier ice. The study has now been published in Nature Climate Change.
Earth's poles are undergoing simultaneous freakish extreme heat with parts of Antarctica more than 70 degrees (40 degrees Celsius) warmer than average and areas of the Arctic more than 50 degrees (30 degrees Celsius) warmer than average.
