All the global warming hysteriacs claim that CO2 is the cause of global warming. I think I can disprove that. CO2 is spread evenly throughout the atmosphere. It blocks outgoing radiation everywhere equally because the physics is simple: X quantity of CO2 will increase the optical depth of the atmosphere by amount Y. Optical depth in simple terms is the opacity of the atmosphere to a given frequency. CO2 absorbs infrared, and so to certain infrared wavelengths, the atmosphere doesn't look clear and it has a hard time escaping. That is the theory.
Now look at the picture below.
You can go to the website, the NOAA website, and make this map. It is a trend map. It shows not the temperature but the rate the temperature is rising. A positive trend means the location is warming (reddish colors); a negative trend meand the location is cooling. Note that from 1971 to 2009, only the northern hemisphere is warming. Antarctica is cooling. Isn't that interesting. CO2 doesn't work in Antarctica!!!
The real answer is that CO2 isn't the cause of the warming or the cooling. It is hyper-illogical to think that CO2 causes warming in the northern hemisphere and cooling south of 60 deg S latitude, that is, in Antarctica.
Then there is another issue. Think of all the caterwalling that we have heard about how global warming is going to melt Antarctica, raise the sea levels and drown all those Bangladeshi's who are too stupid to move out of the way of the rising waters. Given that we know that Antarctica was below freezing in 1971, and we know from the trend map that it has been getting colder over the past 40 years or so, the global warming hyper-illogical hysteriac is asking us to believe that Antarctica is going to melt while it is getting colder by the year!
Only global warming makes people believe such nonsense.
