And I see a downward trend in the mid troposphere since 2002, which according to greenhouse effect theory should be warming more than the surface temperatures:
What on earth could be going on? Well, if you look at the fine print on Carter's graph you find the data set he plotted was "uahncdc.mt", and "mt" stands for mid troposphere. His "Global Average Temperature" is the temperature 6 kms up in the sky, where nobody lives. And what does that silly greenhouse hypothesis predict for the mid troposphere? Well, it says that the lower troposphere will warm (see second graph above), the stratosphere will cool (Look!) and in between them, temperatures in the mid troposphere will not change. Yes, far from the greenhouse hypothesis failing the test, Carter's graph shows that it passed with flying colours."
Gee, I wonder if Carter got the erroneous graph from Junk Science, since his article was on April 11th and JunkScience made it on April 10th? Makes sense to me.
From what I see on that graph, the temperature has bounced up and down some, but is essentially flat - having spend a whole lot of time in the 0C thru 0.2C band during the last 30 years, with short excursions from that.
