The Most Comprehensive Assault On 'Global Warming' Ever
http://www.dailywire.com/news/2071/most-comprehensive-assault-global-warming-ever-mike-van-biezen
Knowing that CO2 is a greenhouse gas and that our industrialized world is adding a large amount of it to the atmosphere on a yearly basis, I accepted the premise that this would cause global temperatures to rise. But one day about 7 years ago, I looked at the ubiquitous graph showing the “global” temperature of the last 150 years and noticed something odd. It was subtle, and as I found out later, disguised so that it would be overlooked.
Before we begin, let’s establish what we know to be correct. The global average temperature has increased since the 1980’s. Since the 1980’s glaciers around the world are receding and the ice cap of the Arctic Ocean has lost ice since the 1980’s, especially during the summer months. The average global temperature for the last 10 years is approximately 0.35 degrees centigrade higher than it was during the 1980’s. The global warming community has exploited these facts to “prove” that human activity (aka burning of fossil fuels) is the cause of these increasing temperatures. But no direct scientific proof or data has been shown that link the current observations to human activity. The link is assumed to be simply a fact, with no need to investigate or discuss any scientific data.

- Temperature records from around the world do not support the assumption that today’s temperatures are unusual.
- Satellite temperature data does not support the assumption that temperatures are rising rapidly:
- Current temperatures are always compared to the temperatures of the 1980’s, but for many parts of the world the 1980’s was the coldest decade of the last 100+ years: If the current temperatures are compared to those of the 1930’s one would find nothing remarkable. For many places around the world, the 1930’s were the warmest decade of the last 100 years, including those found in Greenland. Comparing today’s temperatures to the 1980’s is like comparing our summer temperatures to those in April, rather than those of last summer. It is obvious why the global warming community does this, and very misleading (or deceiving).
- The world experienced a significant cooling trend between 1940 and 1980: During that same 40-year period, the CO2 levels around the world increased by 17%, which is a very significant increase. If global temperatures decreased by such a significant amount over 40 years while atmospheric CO2increased by such a large amount we can only reach two conclusions: 1. There must be a weak correlation, at best, between atmospheric CO2 and global temperatures, 2. There must be stronger factors driving climate and temperature than atmospheric CO2.
- Urban heat island effect skews the temperature data of a significant number of weather stations:
- There is a natural inverse relationship between global temperatures and atmospheric CO2levels: higher temperatures increase atmospheric CO2 levels and lower temperatures decrease atmospheric CO2 levels, not the other way around. Any college freshman chemistry student knows that the solubility of CO2 decreases with increasing temperatures and thus Earth’s oceans will release large amounts of CO2 to the atmosphere when the water is warmer and will absorb more CO2 when the water is colder.
- The CO2 cannot, from a scientific perspective, be the cause of significant global temperature changes: It turns out that between water vapor and CO2, nearly all of the radiation that can be absorbed by CO2 is already being absorbed. Thus increasing the CO2 levels should have very minimal impact on the atmosphere’s ability to retain heat radiated from the Earth.
- There have been many periods during our recent history that a warmer climate was prevalent long before the industrial revolution:
- Glaciers have been melting for more than 150 years
- “Data adjustment” is used to continue the perception of global warming:
