Arctic hotspots study reveals areas of climate stress in Northern Alaska and Siberia
Ecological warning lights have blinked on across the Arctic over the last 40 years, according to new research, and many of the fastest-changing areas are clustered in Siberia, the Canadian Northwest Territories, and Alaska.
An analysis of the rapidly warming Arctic-boreal region, published in Geophysical Research Letters, provides a zoomed-in picture of ecosystems experiencing some of the fastest and most extreme climate changes on Earth.
Many of the most climate-stressed areas feature permafrost, or ground that stays frozen year-round, and has experienced both severe warming and drying in recent decades.
To identify these “hotspots,” a team of researchers from Woodwell Climate Research Center, the University of Oslo, the University of Montana, the Environmental Systems Research Institute (Esri), and the University of Lleida used more than 30 years of geospatial data and long-term temperature records to assess indicators of ecosystem vulnerability in three categories: temperature, moisture, and vegetation.
Building on assessments like the NOAA Arctic Report Card, the research team went beyond evaluating isolated metrics of change and looked at multiple variables at once to create a more complete, integrated picture of climate and ecosystem changes in the region.
“Climate warming has put a great deal of stress on ecosystems in the high latitudes, but the stress looks very different from place to place and we wanted to quantify those differences,” said Dr. Jennifer Watts, Arctic program director at Woodwell Climate and lead author of the study.
“Detecting hotspots at the local and regional level helps us not only to build a more precise picture of how Arctic warming is affecting ecosystems, but to identify places where we really need to focus future monitoring efforts and management resources.”
The team used spatial statistics to detect “neighborhoods,” or regions of particularly high levels of change during the past decade.
“This study is exactly why we have developed these kinds of spatial statistic tools in our technology. We are so proud to be working closely with Woodwell Climate on identifying and publishing these kinds of vulnerability hotspots that require effective and immediate climate adaptation action and long-term policy,” said Dr. Dawn Wright, chief scientist at Esri. “This is essentially what we mean by the ‘Science of Where.’”
The findings paint a complex and concerning picture.
The most substantial land warming between 1997–2020 occurred in the far eastern Siberian tundra and throughout central Siberia. Approximately 99% of the Eurasian tundra region experienced significant warming, compared to 72% of Eurasian boreal forests.
While some hotspots in Siberia and the Northwest Territories of Canada grew drier, the researchers detected increased surface water and flooding in parts of North America, including Alaska’s Yukon-Kuskokwim Delta and central Canada. These increases in water on the landscape over time are likely a sign of thawing permafrost.

Among the 20 most vulnerable places the researchers identified, all contained permafrost.
“The Arctic and boreal regions are made up of diverse ecosystems, and this study reveals some of the complex ways they are responding to climate warming,” said Dr. Sue Natali, lead of the Permafrost Pathways project at Woodwell Climate and co-author of the study.
“However, permafrost was a common denominator—the most climate-stressed regions all contained permafrost, which is vulnerable to thaw as temperatures rise. That’s a really concerning signal.”
For land managers and other decisionmakers, local and regional hotspot mapping like this can serve as a more useful monitoring tool than region-wide averages. Take, for instance, the example of COVID-19 tracking data: maps of county-by-county wastewater data tend to be more helpful tools to guide decision making than national averages, since rates of disease prevalence and transmission can vary widely among communities at a given moment in time.
So, too, with climate trends: local data and trend detection can support management and adaptation approaches that account for unique and shifting conditions on the ground.
The significant changes the team detected in the Siberian boreal forest region should serve as a wakeup call, said Watts.
“These forested regions, which have been helping take up and store carbon dioxide, are now showing major climate stresses and increasing risk of fire. We need to work as a global community to protect these important and vulnerable boreal ecosystems, while also reining in fossil fuel emissions.”

Pilot of Alaska flight that lost door plug over Portland sues Boeing, claims company blamed him
The Alaska Airlines captain who piloted the Boeing 737 Max that lost a door plug over Portland two years ago is suing the plane’s manufacturer, alleging that the company has tried to shift blame to him to shield its own negligence.
The $10 million suit — filed in Multnomah County Circuit Court on Tuesday on behalf of captain Brandon Fisher — stems from the dramatic Jan. 5, 2024 mid-air depressurization of Flight 1282, when a door plug in the 26th row flew off six minutes after take off, creating a 2-by-4-foot hole in the plane that forced Fisher and co-pilot Emily Wiprud to perform an emergency landing back at PDX.
None of the 171 passengers or six crew members on board was seriously injured, but some aviation medical experts said that the consequences could have been “catastrophic” had the incident happened at a higher altitude.
Fisher’s lawsuit is the latest in a series filed against Boeing, including dozens from Flight 1282 passengers. It also names Spirit AeroSystems, a subcontractor that worked on the plane.
The lawsuit blames the incident on quality control issues with the door plug. It argues that Boeing caught five misinstalled rivets in the panel, and that Spirit employees painted over the rivets instead of reinstalling them correctly. Boeing inspectors caught the discrepancy again, the complaint alleges, but when employees finally reopened the panel to fix the rivets, they didn’t reattach four bolts that secured the door panel.
The complaint’s allegations that Boeing employees failed to secure the bolts is in line with a National Transportation Safety Board investigation that came to the conclusion that the bolts hadn’t been replaced.
Despite these internal issues, Fisher claims Boeing deliberately shifted blame towards him and his first officer.
Lawyers for Boeing in an earlier lawsuit wrote that the company wasn’t responsible for the incident because the plane had been “improperly maintained or misused by persons and/or entities other than Boeing.”
Fisher’s complaint alleges that the company’s statement was intended to “paint him as the scapegoat for Boeing’s numerous failures.”
“Instead of praising Captain Fisher’s bravery, Boeing inexplicably impugned the reputations of the pilots,” the lawsuit says.
As a result, Fisher has been scrutinized for his role in the incident, the lawsuit alleges, and named in two lawsuits by passengers.
Spokespeople for Boeing and Spirit AeroSystems declined to comment on the lawsuit.

This storm is already making landfall from the Kuskokwim Delta to Bristol Bay. Expect 8 to 16 inches of snow by Monday night as the heaviest rounds will pass over late Monday morning. Wind gusts up to 40 miles per hour will add blizzard-like conditions with reduced visibility. The Aleutian Chain is bracing for high winds as the gusts up to 70 miles per hour are likely tomorrow. Light rain will pass through as a result of residual moisture of the tail-end of this storm.
The Interior will remain mostly dry tomorrow with mostly cloudy skies stretching over the Brooks Range and into the North Slope. Overnight lows are still quite chilly, sitting near 50 and 60 below zero. Coldest temperatures of the season were record Sunday morning at -50 degrees in Fairbanks, being the coldest temperature since February 2024 which was also -50 degrees. Light snow is possible Tuesday, but otherwise, very calm and quiet weather remains across central and northern Alaska.

Alaska Sees Coldest December In Years | Weather.com
2 Feet Of Snow Traps Drivers In Michigan
Do you think that Alaska is cold during winter? Of course it is! However, the type of cold the state is experiencing right now if unprecedented. How about having consecutive days of temperatures colder than 40 degrees below zero!
This is true for much of the Alaskan interior, particularly near Fairbanks and in between the Alaska and Brooks mountain ranges.
Over the last four days in Fairbanks, temperatures have struggled to reach 40 degrees below zero, with organizers in Fairbanks even postponing their annual New Year’s Eve fireworks show due to the extreme cold.

The temperature in the final few minutes of 2025 in Fairbanks was 43 degrees below zero.
In other words, conditions are unbearably and dangerously cold, even by local standards in Central Alaska.
In Chicken, Alaska, located near the Canadian Border, temperatures dropped as low as 62 degrees below zero! Numerous other locations in the eastern Alaskan Interior have seen temperatures between 50 and 60 degrees below zero.
On top of bringing dangerously cold minimum temperatures, this most recent cold snap has also been more prolonged than usual.
Temperatures in much of Alaska have been largely colder than usual since roughly December 5th, 2025
Some regions in eastern Alaska and the neighboring Yukon Territory in Canada have seen combined December temperatures up to 30 degrees below the climatological average.
For reference, the average December temperature in Fairbanks from 1904 to 2025 is 22 degrees below zero with much of central Alaska having similarly cold December temperatures on average. The city has seen a temperature departure of 18.5 degrees below average for December 2025, ranking as the 8th coldest December on record.
This means that much of east-central Alaska has been stuck between 40 and 50 degrees below for nearly an entire month!
While many factors affect the severity of winters in Alaska, one notable statistic is the unusually high snowfall in portions of Alaska this past December. Fairbanks saw more than double its usual snowfall for the month of December.
Juneau, Alaska’s capital, located in far-southeast Alaska, has seen nearly its entire annual snowfall in December alone, at over 80 inches.
Snowfall promotes cold temperatures by reflecting light from the sun back to space. In Alaska, there is already very little sunlight during the winter due to its positioning on and near the Arctic Circle.
What little sunlight snow-covered portions of Alaska have seen has been quickly reflected back to space by the unusually heavy snowpack.
In Central Alaska, located between the Alaska and Brooks ranges, the heavy snowpack, lack of sunlight, and lack of transport of air from warmer locations have led to the development of an arctic high pressure system, leading to stable conditions and light winds. These conditions cause the land to rapidly lose heat, becoming even colder. With this arctic high pressure is in place, central Alaska has remained cold. However, a slight breakdown in the strength of the high will allow temperatures to warm somewhat (see forecast for next 3 days below).

Fortunately, this pattern will break down as we approach mid-January. A more active storm track from the Pacific is poised to bring wetter and warmer conditions to portions of Alaska, especially towards the middle to second half of the month. While this wetter pattern means snow for most, temperatures will improve, being far more bearable than the current temperatures in the 40 to 50 degree below zero range.
