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.
The North Water Polynya, between Nunavut and Greenland, is one of the Arctic’s most biologically productive areas — and an important part of the food supply for nearby Inuit communities.
Frequent burning over decades reduces the amount of carbon and nitrogen stored in soils of savanna grasslands and broadleaf forests, in part because reduced plant growth means less carbon being drawn out of the atmosphere and stored in plant matter.
Set against the austere peaks of the Western Brooks Range, the lake, looked like it was boiling. Its waters hissed, bubbled and popped as a powerful greenhouse gas escaped from the lake bed.
More than a month’s worth of rain has soaked parts of the state in just a few days, setting records.
Human adaptation to climate change there is not going well
The Alaska Division of Forestry deployed 12 smokejumpers on an estimated 100-acre wildfire burning near the village of Akiachak in southwest Alaska Tuesday afternoon to protect a fish camp and Native allotments surrounding the fire.
Massive landslides triggered by heavy rain blocked the Imphal-Jiribam stretch of the national highway (NH) 37 in Manipur on Wednesday, police said.
The United States’ northernmost city plummeted to a bone-chilling minus 20 degrees Wednesday morning, beating out the previous daily record set in 1973.
Climate change has allowed spotted seals to find new hunting grounds, but the marine mammals ultimately depend on sea ice to survive.
Thinning sea ice has driven more than 50 polar bears ashore on an Arctic archipelago in northern Russia, causing chaos for the local population.
The wildfires can burrow into rich organic material, such as the vast peatlands that ring the Arctic, and smolder under the snowpack throughout the frigid winter.
The pumice blob has the potential to deposit new, healthy coral around the badly damaged Great Barrier Reef, scientists say.
Mycoplasma ovipneumoniae ("Movi") is a respiratory bacterium that can cause disease in susceptible hosts. Previously thought to be host-restricted to sheep and goat species, scientists have identified Movi for the first time in healthy moose and caribou in Alaska; a bison in Montana; mule deer in New Mexico, and diseased white-tailed deer from the upper Midwest.
As of July 21, fishermen in Bristol Bay’s five districts had harvested just more than 42 million salmon.
The wind known as the Diablo is picking up again, the air is dry, there is no rain in sight and the killer wildfires that have scorched the wine country of Northern California remain almost completely uncontained. Officials warned Wednesday that some of the big fires could merge. Amid these grim bulletins, the huge utility company PG&E acknowledged that the extreme winds late Sunday and early Monday had knocked trees into power lines in conditions conducive to wildfires.
