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).

Why I Don’t Deny – Part 2

By Kip Hansen – Re-Blogged From WUWT

Note:  Please read Part 1 before reading this — this is a continuation of that essay (a rather long continuation….)

The last point I made in Part 1 of this essay was this:

The IPCC in their synthesis report for policy makers says that human emissions of greenhouse gases [“atmo­spheric concentrations of carbon dioxide, methane and nitrous oxide”]  and “other anthropogenic drivers,” are  “extremely likely to have been the dominant cause of the observed warming since the mid-20th century.”

The Source Of The Heat

By Willis Eschenbach – Re-Blogged From http://www.WattsUpWithThat.com

Over at Dr. Judith Curry’s always excellent blog, she has a post headlined by a question, viz:

What are the main sources of heat that account for the incremental rise in temperature on Earth?

Let me start by saying that this is a horribly phrased question. Consider a parallel question:

What are the main sources of heat that account for the incremental rise in my body surface temperature when I put on a jacket?
