Summary: Today’s post examines a recent example of climate fear-mongering. Not only is this misleading (at best), but it shows how this propaganda makes it more difficult for us to clearly see the world and respond to its many dangers.
Today’s fear-mongering: “The Siege of Miami“
By Elizabeth Kolbert in The New Yorker
“As temperatures climb, so, too, will sea levels.”
The city of Miami Beach floods on such a predictable basis that if, out of curiosity or sheer perversity, a person wants to she can plan a visit to coincide with an inundation. Knowing the tides would be high around the time of the “super blood moon,” in late September, I arranged to meet up with Hal Wanless, the chairman of the University of Miami’s geological-sciences department. Wanless, who is seventy-three, has spent nearly half a century studying how South Florida came into being. From this, he’s concluded that much of the region may have less than half a century more to go.
… According to the Intergovernmental Panel on Climate Change, sea levels could rise by more than three feet by the end of this century. The United States Army Corps of Engineers projects that they could rise by as much as five feet; the National Oceanic and Atmospheric Administration predicts up to six and a half feet. According to Wanless, all these projections are probably low. In his office, Wanless keeps a jar of meltwater he collected from the Greenland ice sheet. He likes to point out that there is plenty more where that came from.
“Many geologists, we’re looking at the possibility of a ten-to-thirty-foot range by the end of the century,” he told me.
Fear-mongering like this is the path to fame for journalists and scientists in today’s America. Let’s look at Kolbert’s well-written propaganda.
“According to the Intergovernmental Panel on Climate Change, sea levels could rise by more than three feet by the end of this century.”
That is the high-end of the range to the worst of the four scenarios considered by the IPCC’s AR5 (RCP8.5; see the graph above). Professor Wanless forgets to mention that the low-end for that scenario is only 21 inches, that RCP8.5 makes unlikely assumptions about population and technology (e.g., the late 21stC is a coal-burning world like the late-19th), and that the IPCC gives only “medium confidence” to their sea-level projections. See AR5’s conclusions here.
