O=C=O<p>Climate change drives record-breaking heat in Iceland and Greenland challenging cold adapted ecosystems and societies</p><p>On May 15, <a href="https://climatejustice.social/tags/Egilssta%C3%B0ir" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Egilsstaðir</span></a> Airport recorded 26.6°C, breaking the previous record for <a href="https://climatejustice.social/tags/Iceland" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Iceland</span></a>’s highest May temperature, while regions of the country saw temperatures more than 10°C above average (Icelandic Met Office, 2025). The <a href="https://climatejustice.social/tags/Ittoqqortoormiit" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Ittoqqortoormiit</span></a> station in <a href="https://climatejustice.social/tags/Greenland" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Greenland</span></a> saw temperatures reach 14.3°C on May 19, which is more than 13°C above the May average daily maximum temperature of 0.8°C (<a href="https://climatejustice.social/tags/DMI" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DMI</span></a>, 2025). </p><p>These high temperatures were caused by a steady flow of warm air from the south, caused by a high-pressure system near the <a href="https://climatejustice.social/tags/Faroe" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Faroe</span></a> Islands and a low-pressure system south of <a href="https://climatejustice.social/tags/CapeFarewell" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CapeFarewell</span></a>. This <a href="https://climatejustice.social/tags/weather" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>weather</span></a> setup lasted for about nine days, bringing unusually warm weather to the area. While similar patterns have happened before, this <a href="https://climatejustice.social/tags/heatwave" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>heatwave</span></a> stood out because it came so early in the year and lasted for so long.</p><p>While few impacts have been reported, numerous studies demonstrate that unusually high temperatures early in the year can have significant impacts on local ecosystems. These <a href="https://climatejustice.social/tags/ecosystems" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ecosystems</span></a>, adapted to very cold climates, are sensitive to temperature shifts, and disruptions to their delicate balance can lead to consequences not only for the ecosystems themselves, but also for the communities that depend on them. </p><p><a href="https://www.worldweatherattribution.org/climate-change-drives-record-breaking-heat-in-iceland-and-greenland-challenging-cold-adapted-ecosystems-and-societies/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">worldweatherattribution.org/cl</span><span class="invisible">imate-change-drives-record-breaking-heat-in-iceland-and-greenland-challenging-cold-adapted-ecosystems-and-societies/</span></a></p><p><a href="https://climatejustice.social/tags/WeatherAttribution" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WeatherAttribution</span></a> <br><a href="https://climatejustice.social/tags/ClimateScience" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateScience</span></a></p>
