Four weeks of climate data: Northern Temperate Western Hemisphere Temperature Recap

The Western Hemisphere of the Northern Temperate Zone doesn't have as much land or as many people as the Eastern Hemisphere of the same zone, and the temperatures aren't as quite as warm. Still, the region is warming noticeably over the 56 year period, in this case only using grid points that have reports from 90% of the seasons between Winter 1955 and Fall 2010.

Tomorrow, I will continue the trip south through both tropical zones. On Friday, I will finish with the Southern Temperate Zone.

I'm working on a new idea of how to look at the data which I call De-Niñoization. The idea is to subtract the El Niño-La Niña effects from each season to see if the data fits a linear regression better. My guess is that we could see improvement in regions close to the temperature anomaly which spreads across the Indian and Pacific Oceans, radiating in strength from close to the equator, but likely less helpful when we look at regions far from the warming water. My test case will be tropical India vs. Greenland, where we would expect the Indian data to become very nearly linear while the Greenland data might become even more erratic.
