North Pole Melts in Midwinter: Climate Crisis Accelerates

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.

Arctic Tundra Now Emits More Carbon Than It Absorbs: Climate Feedback Loop Accelerates

The 2024 Arctic Report Card reveals the Arctic tundra, warming at up to four times the global rate, is now a net source of carbon dioxide due to increased wildfires and permafrost thaw. These wildfires, intensified by climate change, release significant carbon emissions and accelerate permafrost thaw, further exacerbating the problem. The Arctic’s shift from carbon sink to source worsens climate change impacts globally, underscoring the urgent need for comprehensive understanding and action. Circumpolar wildfire emissions average 207 million tons of carbon annually, highlighting the severity of the situation. This drastic change signals irreversible damage to Arctic ecosystems and broader global consequences.
