Please show me the definitive studies showing a direct correlation between an increase in CO2 and increasing temperatures. There are none. There are a lot of crowing politicians and scientists who are paid from government grants, who have told us it is so. And a bunch of computer simulations, with various assumptions. Atmospheric CO2 is a trace gas, 400 parts per million, 0.04% of the atmosphere. There are many, many factors which influence our climate and its change; and it’s been changing for billions of years. Please tell me why we had the medieval warming period between 900 and 1300. No industrialization back then.
