"Man-made CO2 a primary cause of climate change is just an unproven hypothesis"

From the Statement of H. Leighton Steward, Chairman, plantsneed co2.org and co2isgreen.org:

That man-made CO2 is a primary cause of climate change is just a hypothesis. The hypothesis has not been proven and even the Intergovernmental Panel on Climate Change (IPCC) admits that when they do not say that they are 100% certain it is true. While proving that the hypothesis is true for such a complex subject is probably impossible, it is only prudent to examine whether it can be shown to be false. Webster’s dictionary defines hypothesis as a provisional theory accepted for the sake of argument and testing. Scientists are taught that a hypothesis must withstand its claims being verified or falsified by observing available empirical evidence. When Albert Einstein, in 1905, proposed the theory of relativity, he encouraged other scientists to try and refute it as demanded by the scientific method. Therefore, as a geologist and accustomed to looking back at what has happened in the past to understand why the Earth is physically like it is, I decided to use the same forensic approach to review Earth’s old climates, her paleoclimates. Sir Winston Churchill is credited with saying, “The farther backward you look, the farther forward you are likely to see;” certainly applicable here. Five years ago I began this forensic endeavor thinking I could look back at old temperatures and the often thousands of ppm of atmospheric CO2 and show the tremendous impact such elevated CO2 levels had on Earth’s paleoclimates. I could not find such impacts. I did find however, after reviewing “all” the scientific studies of others, determine that the hypotheses of significant CO2 induced climate change to be false and here is why:

1. Per Dr. Phil Jones, director of the Climate Research Unit (CRU) at East Anglia University, which is the prime source of climate data for the IPCC, despite the steep rise in CO2, there has been no statistically significant warming of the Earth for the last 15 years. Dr. Jones also has publicly admitted that, regarding anthropogenic global warming, the science is not settled.

2. When climate proxies, such as ice cores, tree rings, isotopic analysis of ocean, lake and soil samples, stalagmites, corals, and leaf shapes and stomata densities are cross correlated, they give us a good relative measurement of Earth’s old temperatures vs. those of the last 150 years. These studies indicate that, even at much lower levels of CO2 in the past, the USA’s temperatures today are not the warmest of the last 100 years (1934 was warmer) the last 1,000 years (the Medieval Warm Period was warmer), the last 10,000 years (the Roman Warm Period, Minoan Warm Period and Holocene Optimum were as warm or warmer according to proxy studies), the last 400,000 years (where of the last five interglacials our current interglacial has had the highest CO2 level yet is the coolest of the five) and to go way back, 430 million years ago, when there was glaciations down to 60 latitude while CO2 levels were about 4,000 ppm; over 10 times as high as today.

3. Ice core analysis from Antarctica and Greenland show many intervals where CO2 levels lag or follow temperature changes, not vice versa. A cause does not follow an effect.

4. The physical heat trapping ability of CO2 declines logarithmically or very rapidly and at today’s level cannot “trap” a significant amount of additional heat, consistent with the observations wherein paleotemperatures did not become catastrophically high even at CO2 levels of several thousand ppm.
