Empirical Evidence Shows Temperature Increases Before CO2 Increase in ALL Records

by Tim Ball, September 9, 2018 in WUWT

The question is how does the Intergovernmental Panel on Climate Change (IPCC) determine that an increase in atmospheric CO2 causes an increase in global temperature? The answer is they assumed it was the case and confirmed it by increasing CO2 levels in their computer climate models and the temperature went up. Science must overlook the fact that they wrote the computer code that told the computer to increase temperature with a CO2 increase. Science must ask if that sequence is confirmed by empirical evidence? Some scientists did that and found the empirical evidence showed it was not true. Why isn’t this central to all debate about anthropogenic global warming?
