In central Mexico for the last year the weather has been very beautiful as usual, but cooler than usual with more precipitation.
The only global averages I've seen show that the earth on the whole has been cooling slightly for the last 17 years.
As far as my direct experience living in the US, Europe, and Mexico over the last decade, I personally have not noticed distinct changes in the climate, except for a cooling and reduction of thermal activity over the last few years in central Mexico reflected in my flight logs and the consensus among pilots worldwide, who visit.
That the hurricane that hit the east coast was the most costly is a human factor. There are more structures and infrastructure to damage now than before, and those structures are valued higher now than before. It is not a gauge of warming IMO.
Perhaps due to just a few miscalculations in your figures, a misplaced decimal point, or some issue overlooked, would result in a prediction that passing through a galactic plane causes an earth-like planet cooling, rather than warming. Did you ever consider that?
What if the deep freeze hits on Dec 21st?
