In 1960, CO2 was at a very safe level according to Dr. Hansen – 317 ppm.
If only we could go back to those good old days, when the climate was safe. It was so safe that 30 million people died in China from famine and drought.
In 1960, at least some degree of drought and other bad weather affected 55 percent of cultivated land , while an estimated 60% of agricultural land received no rain at all. The Encyclopædia Britannica yearbooks from 1958 to 1962 also reported abnormal weather, followed by droughts and floods. This included 30 inches (760 mm) of rain in Hong Kong across five days in June 1959, part of a pattern that hit all of Southern China.
I think it is worth taxing our economy into oblivion to go back to Hansen’s safe side of 350. Like in 1917.
“The primary cause of famine almost invariably has been the failure of food crops. This failure has often resulted from a variety of natural causes – long-continued drought, blasting hot winds, insect armies, earthquakes, severe and untimely frosts, and destructive inundations.”
