The emperor penguin has been officially declared endangered due to mass drownings of chicks caused by climate change-induced sea ice melt. These penguins critically depend on stable sea ice for breeding and moulting, but its early breakup has led to catastrophic colony collapses. Projections indicate a halving of the emperor penguin population by the 2080s without urgent action to decarbonize economies. The assessment also highlights the endangered status of Antarctic fur seals, also impacted by climate-driven food shortages, and the southern elephant seal facing extinction from disease.

Scientists have observed a surprising slowdown in the melting of Arctic sea ice since 2005, despite continued increases in carbon emissions. This temporary reprieve is likely due to natural variations in ocean currents, which are limiting ice melting. While the rate of sea ice loss has slowed, the overall area has still halved since 1979, and scientists stress that the climate crisis remains a serious threat. Researchers caution that this slowdown is temporary, and melting is likely to accelerate again in the coming years, continuing to impact the region and contribute to global heating.

Unprecedented warming in the Arctic saw temperatures exceeding 20°C above average on Sunday, surpassing the melting point of ice. This extreme event, linked to a low-pressure system over Iceland and unusually warm seas, resulted in temperatures near 0°C at 87°N latitude. While the exact anomaly is difficult to pinpoint due to limited data in the region, models consistently show a significant temperature increase, highlighting the accelerated warming trend in the Arctic. This rapid warming, nearly four times faster than the global average, poses a significant threat to Arctic sea ice, with its complete summer melt predicted within the next two decades.
