25 April 2011: Dr. David Evans, Australian climate scientist, provided an excellent comment in Canada's Financial Post earlier this month. He points out that the projections of catastrophic global warming by climate models were proved wrong by empirical evidence gathered at the end of last century. According to Evans:
"Weather balloons had been measuring the atmosphere since the 1960s, many thousands of them every year. The climate models all predict that as the planet warms, a hot spot of moist air will develop over the tropics about 10 kilometres up, as the layer of moist air expands upwards into the cool dry air above. During the warming of the late 1970s, '80s and '90s, the weather balloons found no hot spot. None at all. Not even a small one. This evidence proves that the climate models are fundamentally flawed, that they greatly overestimate the temperature increases due to carbon dioxide."
Indeed, the IPCC described this hot spot as a "signature," which would show that the greenhouse effect was driving the recent global warming. But multiple data sets gathered by both weather balloons and satellite measurements do not show the predicted hot spot. To quote Nobel Prize winning physicist Richard Feynman:
"It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong."
