Michael Ivey’s recent letter chastised one of your writers for being “behind the info-curve" on the subject of global warming [“‘Man-Made’ Global Warming,” Dec. 1 Xpress]. His evidence for this position is that the planet has supposedly been cooling since 1998 and that the "Climategate" scandal showed that anthropogenic global warming is a myth.
Neither of these assertions could be more ill-informed. To begin with, choosing 1998 as a starting point is a classic cherry pick — that year was very warm due to an unusually active El Niño. The few years after this were moderate El Niña conditions, which had a cooling effect. A well-explained, short-term drop in temperature for reasons unrelated to carbon dioxide does not refute the existence of global warming, even if it did occur. Moreover, the work of Murphy, et al, in 2009 shows that, even if atmospheric temperatures had dropped after 1998, oceanic temperatures did not. Since ocean warming comprises the bulk of warming, the planet clearly continued to heat after 1998. And as if that wasn’t enough, Fawcett and Jones’ [report] showed in 2008 that the linear trend in global temperatures remained upward for the years 1998 to 2007.
Mr. Ivey's reason for why climate change is supposedly a "myth" never even actually happened!
It is claimed that “Climategate” exposed global warming as a myth. Surely Mr. Ivey doesn't mean the same Climategate in which all researchers were subsequently cleared of all accusations in not one, not two, but three different investigations? Surely he doesn't mean the same Climategate in which [it] was found that "the honesty and rigor of the Climate Research Unit as scientists is not in doubt [and] we have not found any evidence of behavior that might undermine the conclusions of the IPCC assessments," because that would be an awfully flimsy argument.
