Radiative Heat Transfer: Medium Overview, Part 2 of 2.

This is the third article in the series about Radiative Heat Transfer (RHT). In the previous two articles I have described the basics and then gone over one example. That first example is comparable to how the Earth gets energy from the sun. The example was that of a fire warming up a person’s hands […]

The End of an Interglacial

For those that believe that CO2 is the driving force of climate. I would like to show what happened to the Earth 120,000 years ago at the end of the Eemian Interglacial. That period is almost exactly what the projected world will be like if global warming happens. Understanding what it was like and what happened 120,000 years ago is helpful to know what the future holds for the Earth now.

Radiative Heat Transfer: Medium Overview, Part 1 of 2.

This is a continuation of the Radiative Heat Transfer series. If covers the actual energy transfer between two bodies. It is broken into two parts. The first part describes the nature of heat transfer and then builds upon the fire analogy from the first article.

Why CO2 levels change after temperatures change.

Cause and Effect. No issue is more turned upside down in the global warming debate than global temperatures and CO2 levels. That CO2 levels change during the past glacial and interglacial periods is very well documented. It has been used as the basis for climate sensitivity calculations by many warmists. There is one problem with determining the climate sensitivity based on CO2 feedback forcing. It assumes that at least some of the temperature change is caused by changing CO2 levels.

Holocene Cooling Trend

If both of those are correct, then the temperature of the Northern Hemisphere (NH) should be shown to be warmer in the past than it is now. A recent paper (Sundqvist, Zhang, Moberg 2010) says just this. It focuses on the two time periods of 6,000 and 1,500 years ago and uses 104 temperature reconstructions from around the Arctic region to determine the temperature at those two times. It also provides some results for the differences between 6,000 years and 500 years ago. Due to limitations in the data the overall results are for the 6,000 and 1,500 years ago.

The Death of Cap and Trade

Why is this good news? The proposed methods will destroy business in the US and the increased pollution and emissions would simply be exported elsewhere to make up the lost production. So the end result would only be lost jobs and more global pollution and emissions. How is that a good thing?

Radiative Heat Transfer: Simple Overview

The linchpin of the global warming debate centers on what the impact is of increased levels of CO2 in the atmosphere. If there is little to no impact, then there is not problem. If it does make a big difference, then there is reason to worry. That question is answered through the analysis of radiative heat transfer. This is the most misunderstood science in the entire debate. This is meant to be a simple overview of radiative heat transfer (RHT).

NH Summer Energy: The Leading Indicator

That the NH has been cooling for the past 6,000 years has found new supporting evidence in a recent article (Jakobsson, 2010) that states in the abstract:

“The combined sea ice data suggest that the seasonal Arctic sea ice cover was strongly reduced during most of the early Holocene and there appear to have been periods of ice free summers in the central Arctic Ocean.”
