“ASIDE FROM the shifting pattern of monsoon rains and the lengthening winters in the northern hemisphere, one of the most ominous fluctuations is the drop in the mean global atmospheric temperature by 2.7 degrees since the late 1940s
At the same time, the polar ice caps have been growing, and the climatologists think we may be moving into a period of shorter growing seasons and shrinking crop zones, particularly in Canada and the U. S.”

Since you can not understand numbers and math, here is a picture: https://www.climate.gov/news-features/understanding-climate/climate-change-global-temperature. I am sure that one of your wizards can show how 1.2 degree fluctuation over 1 year (an increase) translates to a 2.7 degree decrease
