Antarctic temperatures disagree with climate model predictions

Ohio State University – February 15, 2007

This is an extremely strong article that basically says the models that some scientists are using to predict doom and gloom are not complete or not correct. Interesting that this report comes out only days after IPCC report gave a 90% chance that humans are causing global warming.

I don’t understand how he can say that the models are not exact and then the global population is supposed to take these same models, assume the sky is falling, and spend billions of dollars trying to correct it.

Environmental Effects of Increased Atmospheric Carbon Dioxide

Petition Project – January 1998

This article is states that the effects of CO2 on the climate are negligible if they exist at all. It contends that CO2 levels are definitely increasing but that their effect does not compare to other factors including random climate variation and the influence of the sun.

This petition project was created so that scientists could express their concern regarding the conclusions of the Kyoto agreements. It was supposedly “signed” by 17,000 scientists that questioned the conclusion of the politicians and scientists that gathered at Kyoto.

Joint science academies’ statement: Global response to climate change

The Royal Society – June 2005

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.

Carbon Cycle

Wikipedia

Wikipedia is always a good source of information on technical items needing a simple explanation. In this article we learn about the carbon cycle and its potential influences on the climate.

The cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, the terrestrial biosphere (which usually includes freshwater systems and non-living organic material, such as soil carbon), the oceans (which includes dissolved inorganic carbon and living and non-living marine biota), and the sediments (which includes fossil fuels). The annual movements of carbon, the carbon exchanges between reservoirs, occur because of various chemical, physical, geological, and biological processes. The ocean contains the largest active pool of carbon near the surface of the Earth, but the deep ocean part of this pool does not rapidly exchange with the atmosphere.
