Warming trend means Arkansas River won't meet demand.
This spring has seen record-breaking warm temperatures across Alaska. In the Yukon-Kuskokwim Delta, the Kuskokwim River is melting early — with devastating consequences.
Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts. A new study by Antoni Lewkowicz, a professor in the Department of Geography, Environment and Geomatics at the University of Ottawa and published in the journal Nature Communications, however, shows that areas of cold permafrost can be vulnerable to rising summer temperatures.
March becomes the hundredth month in a row with temperatures above normal. "It is unique and shows how fast climate change is happening in the Arctic," says climate scientist Ketil Isaksen at the Meteorological Institute (MET).
The latest statistics on the mountain hare (or blue hare) population of Finland, for instance, show that the species' numbers are plummeting while the European (or brown) hare is thriving, especially in southern parts of the country.
The Kuskokwim River in Southwest Alaska is taking longer to freeze. Mark Leary, a volunteer for Bethel Search and Rescue, talks about what that means for winter transportation in the region.
Huerfano County says it's preparing for the worst when it comes to this year's flood season and it wants residents to be prepared.
Fish provide a vital source of protein for over half the world's population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food.
If the trend of reduced ice on the world's lakes continues at its current pace, the Canadian tradition of shinny could become a thing of the past, according to new research.
Scientists from NASA and the National Oceanic and Atmospheric Administration have declared 2018 the fourth warmest year on record. It ranks behind 2016, 2017 and 2015, respectively. And it's only going to get warmer from here, they predict.
Greenhouse gas emissions provide extreme warming on Svalbard.
The Arctic is expected to get warmer and wetter by the end of this century and new research says that could mean trouble for infrastructure in Inuvik.
In this corner of the Middle East, a changing climate and debilitating dust storms have brought life to a standstill.
A new study suggests Greenland ice has hit a new tipping point with unprecedented melting since the early 2000s — and this will have consequences for East Coast cities.
The fishing communities of Saugeen First Nation and Chippewas of Nawash are finding higher winds and warmer temperatures are affecting populations of lake whitefish in Lake Huron and Georgian Bay, which many rely on for their livelihoods.
Slik har Norge forandret seg. Sakte, nesten umerkelig.
Only one, located in British Columbia's Thompson River, is considered stable.
Global warming has already resulted in more forest fires out West, according to the latest National Climate Assessment. The future could see more of the country burn.
A new study shows loss of habitat in Canada’s Peace-Athabasca Delta is likely responsible for the decline of semi-aquatic muskrat, and could have larger implications.
Western Lake Erie's annual summer algal blooms are triggered, at least in part, by cyanobacteria cells that survive the winter in lake-bottom sediments, then emerge in the spring to "seed" the next year's bloom, according to a research team led by University of Michigan scientists.
