No, dumb ass, I equate 420 ppm with 116 degrees in June in Portland, Oregon, and 121 in Lytton, BC. One of the effects of global warming changing our climate is extreme weather events. Droughts and high winds that create fire storms that burn 1000+ square miles of forest in just one fire. Storms that produce 40 to 60 inches of rain in just a couple of days. North Dakota weather for a week or more in Texas in February. Floods in the north EU nations while the south EU nations are having catastrophic fires.
