Dr Ed Berry writes: "IPCC’s claim that human emissions caused all the rise in atmospheric CO2 since 1750 is, without question, the most costly deception in the history of mankind. People think they can save the world if they can stop human emissions of CO2, but data and simple physics prove them wrong. Climate alarmists have money, critical government jobs, control of scientific organizations and journals, influential university positions, and well-funded environmental organizations."
