Forty-two reindeer were found foraging among the skeletal remains of a herd on St. Matthew’s Island, a remote patch of Alaskan land in the Bering Sea. What makes it most puzzling is that only three years earlier, the same herd numbered 6,000 animals.
Hurricanes form in the tropics, feeding on very warm ocean waters. As they track northward, they may transform to an extratropical storm with an added punch, sometimes reaching southern Greenland, Alaska, and even Arctic latitudes of the North Atlantic.
Researchers warn the shift can have dire consequences for animals, like penguins, who breed and rear their young on the sea ice while also hastening global warming by reducing how much sunlight is reflected by white ice back into space.
A handful of super powerful tropical cyclones in the last decade has a couple of experts proposing a new category of whopper hurricanes: Category 6.
As the Arctic continues to warm faster than the rest of the planet, evidence mounts that the region is experiencing unprecedented environmental change. The hydrological cycle is projected to intensify throughout the twenty-first century, with increased evaporation from expanding open water areas and more precipitation. The latest projections from the sixth phase of the Coupled Model Intercomparison Project (CMIP6) point to more rapid Arctic warming and sea-ice loss by the year 2100 than in previous projections, and consequently, larger and faster changes in the hydrological cycle. Arctic precipitation (rainfall) increases more rapidly in CMIP6 than in CMIP5 due to greater global warming and poleward moisture transport, greater Arctic amplification and sea-ice loss and increased sensitivity of precipitation to Arctic warming. The transition from a snow- to rain-dominated Arctic in the summer and autumn is projected to occur decades earlier and at a lower level of global warming, potentially under 1.5 °C, with profound climatic, ecosystem and socio-economic impacts. The Arctic warms faster than other areas of the planet, which also influences precipitation. Here, the authors show that the latest CMIP6 model ensemble shows a faster Arctic warming and sea-ice loss, causing an earlier transition from a snow- to a rain-dominated Arctic than previously thought.
Global average temperature exceeded previous record by substantial margin
Shaktoolik, a village in Alaska, is still waiting for aid from FEMA to rebuild a protective berm that was destroyed by a typhoon, leaving the community vulnerable to storms and erosion.
An assessment by geotechnical experts will need to be completed in order to know the stability of the slide and understand continuing risk.
Hail severity will increase in most regions of the world while Australia and Europe are expected to experience more hailstorms as a result of climate change, an international review led by a UNSW Sydney researcher has found.
As grape harvest time nears across Greece, winemakers are worried about the impact on output from a succession of extreme weather events.
Cecelia Brooks remembers a time when the deep forest of New Brunswick was so cold, snow could still be found in its depths in August. That rarely happens anymore. Brooks, who lives on St. Mary's First Nation in Fredericton, is one of many Indigenous people in the Wabanaki region who say climate change is threatening traditional plants and medicines. Those changes, Brooks says, could alter their way of life.
Several shipments of food made it into Clyde River, Nunavut, this week after delays due to weather. It's just the latest in a series of problems in the community that's been battered by weather since late January.
Homes, fish camps, and destroyed subsistence gear that haven’t already been repaired or replaced still won’t qualify for individual assistance under new policies that take effect in March 2024.
Ida Wessman, 28, bought her family's herd of reindeer after her father passed away five years ago. "It's been going pretty well. With this industry you've got high points and low points," Wessman said, alluding to severe 2019-2020 weather that killed 15,000 of the animals.
"Even ordinary rainfall can be regarded as an extreme event in polar regions," Dou said. This is because rain-on-snow events, which occur when rain falls onto an existing snowpack and freezes into an ice crust, impact wildlife, infrastructure and local communities.
Weakened wind patterns likely spurred the wave of extreme ocean heat that swept the North Pacific last summer, according to new research led by the University of Colorado Boulder and the Scripps Institution of Oceanography at the University of California San Diego. The marine heat wave, named the "Blob 2.0" after 2013's "Blob"; likely damaged marine ecosystems and hurt coastal fisheries. Waters off the U.S. West Coast were a record-breaking 4.5 degrees F (2.5 degrees C) above normal, the authors found.
Task Force Iqaluit is making plans to move its water purification operation indoors, after a winter storm knocked down the tent housing its purifying system. Meanwhile, city staff are being redeployed due to the crisis, leading to some cuts to recreation services.
Most of Southcentral Alaska has seen near record-setting snowfall this winter. The state of Alaska extended its annual deadline for residents to swap out their studded winter tires by 15 days due to what they called “prolonged winter weather.”
