A recent report examines an extreme May 2025 heatwave in Iceland and Greenland, attributing its severity directly to climate change. The event saw record-breaking temperatures, with Iceland reaching highs over 13 °C above average and Greenland experiencing abnormal warmth that significantly accelerated ice sheet melt. The analysis found that human-induced climate change increased the likelihood of such a heatwave by approximately 40 times and intensified its temperature by about 3 °C. The heat triggered widespread impacts: infrastructure built for colder climates failed under the stress of high temperatures, sea ice degradation disrupted mobility and traditional livelihoods, and the Greenland ice sheet melted at a rate 17 times above normal. These findings highlight the vulnerability of cold-adapted regions to even slight increases in global temperatures. The report underscores the urgent need for Arctic-specific adaptation strategies and rapid global emissions reductions to prevent future heat extremes and their cascading environmental and social consequences.
