Greenland has officially opened its new international airport in Ilulissat, completing a three-year infrastructure expansion program. The facility features a 2,200-meter runway, replacing the previous 845-meter strip, and enables direct flights to Copenhagen. This development aims to boost tourism and economic independence for the Arctic territory.
Thawing permafrost, covering 20 million square kilometers, is releasing ancient carbon and destabilizing Arctic infrastructure. Experts warn that heatwaves and fires are accelerating this process, potentially releasing 200 to 300 gigatons of CO2 equivalents by 2100. While the global system may not tip simultaneously, local irreversible changes are already occurring, threatening ecosystems, water quality, and economic stability in regions like Alaska and Siberia.
Oslo-based Over Easy Solar installed 6,400 vertical solar panels on the roof of Tromsøterminalen, a major Arctic cold store in Norway. The 320 kWp array uses no bolts or ballast, relying solely on friction and low wind lift to stay secure. This vertical orientation prevents snow accumulation, which typically renders flat panels ineffective in northern climates. The installation was completed by a three-person crew in four days, marking the world’s largest vertical rooftop solar system. While specific yield data from the new roof is pending, comparable research sites show a 54% performance advantage over conventional tilted arrays in high-latitude regions.
