Empirical Evidence Shows Temperature Increases Before CO2 Increase

By Dr. Tim Ball – Re-Blogged From 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?

The most important assumption behind the hypothesis that human activities are causing global warming is that an increase in global atmospheric CO2 will cause an increase in the average annual global temperature. The assumption became almost the total focus of the IPCC because of the definition of climate change given them by the United Nations Framework Convention on Climate Change (UNFCCC).

Vostok Ice Cores

By Richard Taylor – Re-Blogged From http://www.WattsUpWithThat.com


Our current understanding of climate was influenced profoundly by the publication (J.R. Petit, et al., 1999) of deuterium (2H) measurements from metre 8 to metre 3310 of the Vostok ice-core, indicating the temperature of the nearby atmosphere from 1800 to 421000 BC. Some authorities claim, and many believe, that unprecedented climate-change has begun in recent years which threatens the very existence of human-kind. The uppermost 7 m of the Vostok core might have provided a unique perspective on this frightening claim, but the available data (https://www.ncdc.noaa.gov/paleo/study/2453) have only a mean deuterium value of -438 ‰ for this recent portion, well below the highest value in the core of -414.8 ‰.
