I have recently come across this excellent infographic that explains so much about human development and the various climates that we have lived through.
The thing to do is to scroll down to the last 200 or so years and see how economic growth has contributed to a rightward movement in the Earth’s average temperature. Compare this to the very long almost strightline that covers thousands and thousands of years. The dotted lines show scenarios that may happen.
