NASA’s illustration in the top left, suggests the whole Arctic is warming by 8C above global average which they then blame on rising CO2 and a climate crisis.

In contrast, National Weather Service data on January 29th, 2023, at 60 degrees latitude just south of the Arctic Circle, reveals that ocean currents, derived from the Gulf Stream, are melting sea ice and causing high temperatures where less ice ventilates more heat.

At 60 degrees latitude, the Norwegian Current melts ice and raises winter temperatures to 1.9C (35.4F) in contrast to waters west of Baffin Island where there is no ice melt, and a bone-chilling -39C (-39F), clearly showing the insulating effects of sea ice.

Accrodingly, Kahl (1993) measuring temperatures over sea ice published Absence of evidence for greenhouse warming over the Arctic Ocean in the past 40 years.

The lower left illustration shows where warm Atlantic waters are intruding into the Arctic and the relative amounts of heat carried by currents circulating the Arctic Ocean. The greatest amount of heat enters the Norwegian and Barents Sea. Virtually no warm water reaches the waters west of Baffin Island.

In the lower right, NOAA’s illustration of the 2020 maximum winter ice shows most of the Arctic is covered in sea ice. The exception being the Barents Sea where warm intruding waters melt the ice. The blue circle represents the Arctic Circle and the red rectangle highlights how much sea ice melts inside the Arctic Circle due to warm water intrusions.

Understanding the variations of Arctic temperatures and their relationship to intruding Atlantic water, makes it very clear, it is NOT CO2 that is melting sea ice.
