This map includes local observations and news articles of unusual and extreme environmental events that occurred primarily in the far north (above 54 degrees N latitude) during March 2025. These posts were compiled from the Local Environmental Observer (LEO) Network, and used here for exploring environmental change as part of 'The Northern Climate Observer' newsletter. Map by M. Brubaker.
Analysis was performed with AI assistance (03 Mini) to help identify four overarching themes from 27 articles. The focus is on climate-related phenomena, biodiversity challenges, and human response to environmental hazards, with specific examples from multiple articles included.
Climate Anomalies and Weather Extremes Unseasonable Conditions
Iceland: Reykjavík faced dramatic weather events with incidents like thunder and lightning storms in the capital region being unusual for the season (source).
Alaska: In Anchorage, the snowpack dropped to zero unusually early in March, a rare occurrence that typically happens later in April, signaling unusual warmth and climate variation (source). Storms and Flooding
Iceland: Coastal flooding from severe storms impacted areas such as Seltjarnarnes, causing significant damage (source).
Norway: Trondheim experienced its wettest five-day period in over a century, disrupting daily life with excessive rainfall (source). Impact of Warm Weather Ecosystem Changes and Risks
Sweden: The discovery of Asian fungus 'citronmussling' in Skåne raises concerns about ecological competition in Swedish forests, threatening native species (source).
Alaska: Warmer temperatures prompted an earlier start to the fire season and increased bear activity, challenging usual safety and ecological norms (source 1, source 2). Ice Melt and Floods
Russia: In Chelyabinsk, ice melt due to unseasonably warm weather led to flooding, affecting infrastructure and necessitating evacuations (source). Extreme Events and Natural Disasters Avalanches
Norway and Alaska: An increased incidence of avalanches, notably in Abisko, Sweden (source), and specific fatalities in Alaska (source), signals a heightened risk associated with changing snow conditions. Earthquake Activity
Alaska: An earthquake swarm near Adak, including a significant 6.2-magnitude quake, emphasizes the region's tectonic activity and potential risks (source). Human and Wildlife Interactions Wildlife Health Issues
Sweden: A Salmonella outbreak among small birds in Piteå poses cross-species health risks, notably with domestic cats (source). Human Safety and Infrastructure
Alaska: Natural incidents such as sandstorms during the Iditarod race (source) and road-blocking landslides in Ketchikan (source) led to human challenges, emphasizing the need for adaptable strategies.
Conclusion The articles collectively highlight significant environmental changes marked by unusual weather patterns, ecological disturbances, and increased natural hazards. These phenomena underscore escalating climate variability and the need for robust adaptive measures to effectively respond to and mitigate impacts on communities and ecosystems.

Capital area residents experienced an unexpected display of lightning followed by a powerful thunder clap as stormy conditions gripped southern Iceland.
UAF Geophysical Institute space physicist Peter Delamere recently rode his fat-tire bike over frozen vegetation south of the Alaska Range until his tires finally bit snow a bit farther north.
Researchers warn that the Asian edible fungus 'citronmussling' may spread in Swedish forests and outcompete native species.
A pilot rescued with two young family members after they survived a night on the wing of an airplane partially submerged in a Kenai Peninsula lake is a student pilot who was not authorized to fly with passengers, according to a U.S. official and federal aviation records.
A powerful snowstorm battered Russia’s Far East Kamchatka Peninsula, grounding flights, stranding motorists, and triggering avalanche warnings in Petropavlovsk-Kamchatsky.
A 16-year-old snowmachiner from Soldotna was killed in an avalanche at Turnagain Pass, Alaska, highlighting the ongoing danger in the area due to unstable snowpack conditions.
A magnitude 6.2 earthquake struck southeast of Adak early Friday, part of a continuing swarm with several quakes measuring 4.0 or higher since Wednesday.
A 39‐year‐old Slovenian man recounts his dramatic ordeal of being buried under snow for over 7 hours during an avalanche in Lyngen, while rescuers continue searching for a missing woman.
A rescue operation has been initiated after an avalanche dragged a helicopter that was on the ground in Abisko National Park, with two persons currently reported missing.
A large landslide just outside Ketchikan, Alaska, buried a road on Thursday, displacing hundreds and forcing school closures, though no injuries were reported.
Unseasonably warm weather triggered ice breakups and subsequent flooding in Russia’s Chelyabinsk region, prompting emergency evacuations and road closures as rising water levels affected multiple rivers.
Alaska state officials have advanced the start of the official fire season to March 17 in Southcentral, Southeast, and Western Alaska due to unusually low snowpack and warmer temperatures. The change aims to mitigate increased wildfire risks in these populated regions.
Two small wildfires on the Kenai Peninsula have been reported and quickly contained as the region enters an early fire season. Burn permits are now required on all state, private, and municipal lands due to early warm temperatures and low snowpack.
Mild weather in Nordland, Norway, is causing hazardous road conditions with avalanche risks, road closures, and chain traffic, leading to significant travel disruptions including school bus delays.
Authorities in Troms have ordered the evacuation of 45 residential units in areas including Oldervik and Breivikeidet in Tromsø due to a significant avalanche risk, although some residents choose not to comply.
SMHI has upgraded the warning for storms in the northernmost mountains to an orange warning for strong winds and snow on the bare mountains, from Tuesday morning. Several places are also warned of dangerous conditions and a high risk of avalanches has been issued in the Abisko-Kebnekaise area.
There is unusually low snow coverage and exposed ice on the North Slope. The tundra lakes are more visible and sea ice is lower than normal.
Researchers warn that shorter winter sea ice seasons around Prince Edward Island reduce the coast’s natural defense against winter storms, leading to increased erosion.
Area biologists recommend securing attractants as warmer weather leads to earlier bear activity on the Kenai Peninsula, prompting calls for caution among residents.
The classic long-distance ski race 7-mila has been cancelled due to a lack of snow for the first time since 2014, affecting over 130 registered participants and causing financial concerns for the organizers.

The central Norwegian region of Trøndelag is known for its inclement weather; per an ongoing tourism campaign, while “the food is iconic,” the weather is “chronic.” But the past week in Trondheim has been special even by local standards, and not in a good way. The city, according to Norwegian media, has to reach back more than a century to find a wetter five-day stretch than the one it just experienced, with 4.5 inches of precipitation.
