What would be interesting to know is what kind of research predicted global cooling. Of course, the earth is/was seemingly in a cycle of ice ages coming and going. And…we are due for another ice age. Good to know that Global Warming by CO2 emissions is currently so strong that it would over power any of the previous ice ages. Still…all they had in the 70’s to predict an ice age coming was the limited trend data available then. Climate data has greatly increased since then. The result…no more predictions of global cooling.
