Climate Change Evidence: Northern Hemisphere Temperature Anomalies for 12-1-2014

Below are two images mapping surface air temperature across the Northern Hemisphere.

This first image shows temperatures based on actual readings and computer-generated interpolations; it also shows the North Pole, identified with a red box. Look closely and you will see that the two green areas are the northern Pacific (upper-left) and northern Atlantic (center-right). The smaller magenta areas (intense cold) are over Siberia (top) and Greenland (just above center).

Comparing the two images allows us to identify anomalies, which include:

  • Air temperatures at the North Pole region are substantially elevated in 2014. In fact, on 12/1/2014, the North Pole temperature is roughly identical to that at St. Louis, MO, at 39-degrees north latitude. In contrast, according to the historical data, the average temperature at the North Pole is normally colder than all points in North America south of 70-degrees north latitude.
  • Energy flowing into the north Atlantic region via the Gulf Stream is substantially enhanced, and now pushes non-freezing temperatures all the way to the northern tip of Greenland.
  • On the south edge of the image, at lower latitudes, the temperatures are noticeably hotter (more orange and red), especially over water. See for example the Amazon basin and African nations around Ghana.
  • While the North Pole and Arctic Ocean areas are considerably warmer, the cold air that sets in during the dark of each northern winter appears to be regularly splitting into two intense cold cores, which then define weather patterns across nations to the south. One core tethers over Greenland, Baffin Bay and islands to the west; the other core tethers over central Siberia. Thus, it appears we are seeing the start of an enormous change in weather-creating architecture. The traditional single cold air core spinning over the pole (and generally maintained by strong Jetstream flows) has become two smaller cores that are each more prone to both drifting and periodic disintegration.
