The relocation between from Newtok to Mertavik has taken time and community members stay patient as local, state, and federal agencies figure out the complex funding and logistical hurdles.
The region of Catalonia, northeastern Spain, is in its worst drought since measurements began. The sheep reservoir supplies water to the city of Barcelona.
The 'phantom' Tulare Lake once the biggest lake west of the Mississippi and drained for agriculture purposes is slowly reemerging.
Climate change has been observed for hundreds of years by the plant specialists of three Odawa Tribes in the Upper Great Lakes along Lake Michigan. Sleeping Bear Dunes National Lakeshore is the focus of two National Park Service (NPS) studies of Odawa Traditional Ecological Knowledge (TEK) of plants, ecosystems, and climate change. Data collected during these studies contributed to developing Plant Gathering Agreements between tribes and parks. This analysis derived from 95 ethnographic interviews conducted by University of Arizona (UofA) anthropologists in partnership with tribal appointed representatives. Odawa people recognized in the park 288 plants and five habitats of traditional and contemporary concern. Tribal representatives explained that 115 of these traditional plants and all five habitats are known from multigenerational eyewitness accounts to have been impacted by climate change. The TEK study thus represents what Native people know about the environment. These research findings are neither intended to test their TEK nor the findings of Western science.
World leaders already have many options to reduce greenhouse gas pollution and protect people, according to the United Nations report.
A study published in Nature Climate Change examined how 10 big rivers in the Arctic had moved 50 years, and found they did not migrate as much as expected.
This weekend marks the third anniversary of the World Health Organization’s declaration of the global pandemic — and Juneau’s wastewater is awash with COVID.
At times, the water level in the river Skjoma in Narvik is so low that the salmon freezes to death. But Statkraft has refused to release more water into the watercourse. Now the NVE intervenes.
National Weather Service says Alaska has been lucky to have three La Niña years. Due to climate change we could see a shift into warmer La and El Nino's.
Streams in Alaska are turning orange with iron and sulfuric acid. Scientists are trying to figure out why
Warming soils beneath Utqiagvik are triggering erosion that threatens homes, infrastructure and cultural resources. The North Slope has seen some of the fastest changes in coastal erosion in the nation.
Dozens of once crystal-clear streams and rivers in Arctic Alaska are now running bright orange and cloudy, and, in some cases, they may be becoming more acidic. This otherwise undeveloped landscape now looks as if an industrial mine has been in operation for decades, and scientists want to know why.
These lakes form because warm temperatures in the Arctic are melting the permafrost.
Yukon River chinook salmon runs have been steadily declining, with 2022 the smallest run on record. As the fish disappear, Yukon First Nations fear the cultures and traditions built around the salmon over countless generations will too.
The Arctic is no stranger to loss. As the region warms nearly four times faster than the rest of the world, glaciers collapse, wildlife suffers and habitats continue to disappear at a record pace.
Scientists have analyzed 1.4 million global lakes, saying the sky is "thirstier" than ever.
As big fish crop up in unexpected places, experts say that they're relocating to new environments as waters warm.
The temperature on the delar of Svalbard has risen to twice as fast as the time period known. No can forecast at the Norwegian Meteorological Institute document the greatest warming in the world.
While mining giant Nornickel has said the local ecosystem is "satisfactory," environmentalists paint a different picture.
Beavers were not previously recognized as an Arctic species, and their engineering in the tundra is considered negligible. Recent findings suggest that beavers have moved into Arctic tundra regions and are controlling surface water dynamics, which strongly influence permafrost and landscape stability. Here we use 70 years of satellite images and aerial photography to show the scale and magnitude of northwestward beaver expansion in Alaska, indicated by the construction of over 10,000 beaver ponds in the Arctic tundra. The number of beaver ponds doubled in most areas between ~ 2003 and ~ 2017. Earlier stages of beaver engineering are evident in ~ 1980 imagery, and there is no evidence of beaver engineering in ~ 1952 imagery, consistent with observations from Indigenous communities describing the influx of beavers over the period. Rapidly expanding beaver engineering has created a tundra disturbance regime that appears to be thawing permafrost and exacerbating the effects of climate change.
