Mean temperature calculation’s are at 58 degree presently. Now where near the calculated 75 degrees when The dinosaurs Roamed the earth. Look at charts. They go up and the go down. Some say it has to do with the elliptic cycle of the earth around the sun, basic it get farther away and earth enters ice age. There NOTHING human’s can do to control it. So they say, but I sure a carbon tax will fix it.
