Dedicated to the balanced discussion of global warming
This is a great article. The article discusses other potential causes of global warming than human action. It also takes a fairly cynical look at the politics of the money involved. If you have an open mind on global warming issues, this article is well worth your time.
Beyond the natural carbon cycle and greenhouse warming, there are some other serious causal explanations for global warming. Among the suspects are, of all things, the sun and its fellow stars.

This is a very long article that has quite a few good points in it. The article is a series of questions and answers on the subject. The author’s goals were to try and put some simple facts behind many of the myths and rumors regarding weather and the things that influence the weather.
This article should be standard reading for anyone that is interested in the details behind global warming.
Only the structure constraining internal-external convection will function as an effective greenhouse. Greenhouse gases categorically do not inhibit convective activity and so are not like a physical greenhouse.

This is a very interesting article that continues the thought process that methane is the worst offender in the battle of the greenhouse gases. The article contends that the huge livestock populations produce waste which produces methane in quantities that the environment cannot handle. The solution is to change the diet of a large portion of the population so that we need less livestock and therefore less of their waste.
While this is an interesting proposition, I am not sure that the science is 100% sound and I also am not sure that the cost is worth the benefit. There is no explanation of how to provide the nutrients that are needed by the human population without livestock.READ MORE

This is an article (or maybe should be called a statement) from several scientific bodies proclaiming that the earth is getting warmer and it is man-made pollutants that are causing the problem.
…there is now strong evidence that significant global warming is occurring1. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001)2. This warming has already led to changes in the Earth’s climate.
…human activities are now causing atmospheric concentrations of greenhouse gases – including carbon dioxide, methane, tropospheric ozone, and nitrous oxide – to rise well above pre-industrial levels. Carbon dioxide levels have increased from 280 ppm in 1750 to over 375 ppm today – higher than any previous levels that can be reliably measured (i.e. in the last 420,000 years). Increasing greenhouse gases are causing temperatures to rise; the Earth’s surface warmed by approximately 0.6 centigrade degrees over the twentieth century.
This is an interesting analysis. The article basically says that we are foolish to be focusing on CO2 as a potential for the greenhouse gas effect for global warming. Rather, we should be focused on methane. While I am not sure that I totally by into the suggestion that the solution of this problem is that the human race should become vegetarians, the article does point out many good points. If this article is true, why are we spending billions of dollars to reduce CO2 emissions if it is not the true culprit?READ MORE
