People who believe in anthropogenic global warming due to CO2 concentrations rely on data that the earth has warmed by about 1 degree Centigrade over the past century. This increase averages 0.1 degree per decade, and is a very small temperature difference to measure.

Some scientists have been studying whether the temperature measurements are accurate. One study in Alaska, over a 4 year period, sought to determine whether measurements in urban areas could be affected by the anthropogenic heat islands which are created in cities. An abstract of the study is Linked Here and is entitled: ” Four Winters of Urban Heat Island Data from Barrow, Alaska (USA) “

Another site, SurfaceStations.org has just recently been established to gather data on the accuracy of the 1221 temperature stations that make up the U.S. Historical Climatology Network (USHCN), and the approximately 3200 surface station records which make up the Global Historical Climatological Network (GHCN). Some of the temperature stations are located in areas where Urban heat could significantly affect the accuracy of the reading.

Yet another Article in Climate Science claims that the Report entitled:

Observations: Surface and Atmospheric Climate Change In: Climate Change 2007: The Physical Science Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change(IPCC),

was biased and clearly cherrypicked information on the robustness of the land near-surface air temperature to bolster their advocacy of a particular perspective on the role of humans within the climate system. As a result, policymakers and the public have been given a false (or at best an incomplete) assessment of the multi-decadal global average near-surface air temperature trends.

If the temperature readings are inaccurate, then the entire basis of anthropogenic global warming argument may be suspect.

Since 1997, climate-change research is literally exploding with new findings. Only now, is this new evidence being published about alternative theories for global warming.

Here is a recent article which describes the effect of the sun and cosmic rays on the earth’s temperature. The article suggests that global cooling will be a larger concern for all of us by the year 2020.

Here is the Link to the article, which is entitled: “Read the Sunspots”.

And another article entitled: “Forget Warming - Beware the New Ice Age.”

I came across this clip on Powerline, which I found interesting. It reflects a trend in politics that is common on many issues. The party that is not in power is critical of a given position, until that party assumes power itself.

Here is an excerpt of a 1992 speech given by then U.S. Senator Al Gore, who was a candidate for Vice President, criticizing President George H.W.Bush for not being aggressive enough against Saddam Hussein, who was “accumulating chemical, biological and other weapons of mass destruction, including an interest in nuclear weapons.”

Here is the Link to the Video of the speech.

It is an interesting speech, when compared to the arguments heard from Democrats today.
