Hey, remember how all the global warming skeptics used to say that warming wasn’t happening because the satellite data didn’t show a warming trend. Until in 2005 when they found a mistake in the satellite data and what do you know, it did show warming. And they stopped using that argument? Well Bob Carter isn’t going to let a little thing like that bother him. He is still claiming that satellite data shows no warming.
Here he is in the denialist Daily Telegraph:
However, our most accurate depiction of atmospheric temperature over the past 25 years comes from satellite measurements (see graph below) rather than from the ground thermometer record. Once the effects of non-greenhouse warming (the El NiÃ±o phenomenon in the Pacific, for instance) and cooling (volcanic eruptions) events are discounted, these measurements indicate an absence of significant global warming since 1979 – that is, over the very period that human carbon dioxide emissions have been increasing rapidly. The satellite data signal not only the absence of substantial human-induced warming, by recording similar temperatures in 1980 and 2006, but also provide an empirical test of the greenhouse hypothesis as understood by the public – a test that the hypothesis fails.
And gee whiz his graph of satellite temperatures shows almost no warming.
But at the MSU site where his data comes from you see this graph that shows strong warming:
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.
Is Bob Carter clueless or is he dishonest? You’ll have to decide that for yourselves, but there is a bit more evidence in his article:
That the satellite temperature record shows no substantial warming since 1978, and that even the ground-based thermometer statistic records no warming since 1998, indicates that a key line of circumstantial evidence for human-caused change (the parallel rise in the late 20th century of both atmospheric carbon dioxide and surface temperature) is now negated.
Carter can only contrive a “no warming” result in the surface record by starting in 1998, an El Nino year. But to get a “no substantial warming” in the satellite record, he threw out all the El Nino years. You will seldom see a more blatant example of cherry picking.
