There is to much spin in the climate date. One of the "facts' they use in promoting their religion is the pH of the oceans are going down because of the increase in Carbon Dioxide. This "fact" was based on the observation that there was a decrease in the pH of about 0.06 units, The standards they used of make the measurements are guaranteed by the vendor to be =/-0.05. That makes their "fact" bogus.
They talk about the climate change of 0.1 degrees. There is no statistical method for evaluating date the would call that a change with on any day of the year, the temperatures taken all over the earth will vary over 100 degrees. (-40F at the winter pole to 130F in the equatorial deserts. For a change to be significant by a simple T test the change has to be greater the about 3 times the standard deviation of the measurements. If the global warning people presented a data set like this for drug approval they would be laughed out of the office.
I also like the studies on hurricanes that make the statement that the number of hurricanes have been increasing since the 1970, The low point in the Hurricane cycle which is based on the hurricane counts for several hundred years.
I was really impressed when the global warmer on a ship trapped in the summer ice in Antarctic told the people suffering in one of the coldest winters in recent history, that they should still being prepared to face the global warming.
Finally if you leave the Global warming religion and look at other field you will find the long term studies do not support the global warming data. This is one recent study
The biggest questionable item in the data of Climate Change is comparing the data from a point that went from a rural area 50 years ago to an asphalt parking lot today. It does not take a genius to realize the Asphalt parking lot will definitely show an increase temperature when compare to its preparking lot days. Every day we pave more parking lots, build more houses with asphalt roofs, and other heat capturing structures, see the temperature change and say the carbon dioxide from a coal burning power plant is causing it.
