Its a long period not just one month. The fact that many tornadoes never get rated helps support my point, that this years larger than normal crop of high rated tornadoes doesn't really tell us anything. The fact that we went so long without one hitting the top rating shows that your claim that we are getting more top rated tornadoes is false (if your claim was that we are getting more very powerful tornadoes whether or not they are rated, then its just "unsupported" rather than shown to be false) As for weather records of one type or another for multiple parts of the country in the same year, that's hardly unusual, there are many different types of weather records, and quite a few different areas or sections of the country. I'm actually much more sympathetic to the idea that the globe is warming, or even that its warming largely due to human emission of CO2, then I am for your arguments for those points. Your arguments range from weak, to totally falling apart, but just because you have weak arguments doesn't actually show that you are wrong. There is some evidence of recent cooling, but the general trend is up (and has been for quite some time), I would expect human CO2 emission to contribute to that. The claim that its the dominant factor is more dubious, but still possible. I won't claim "the earth is not and has not been warming because of anthropogenic CO2". I just think your arguments for the idea are weak, and I think the claims of the doomsayers on this issue over the top and unreasonable.
