If you are the President’s chief scientific advisor then you have a duty to be informed and keep informed, and a duty to refrain from making indisputably false statements. Such responsibility is obviously too much for John Holdren, who has shown himself again as an inveterate liar (see earlier posts All who hate Me love Death and Growth of Crops, Weeds, CO2 and Lies). In a recent interview with New Yorker writer Elizabeth Kolbert, Holdren repeats the litany of ‘evidences’ for anthropogenic global warming, which he must know are patently untrue if he has read any scientific literature over the past few years. Holdren said
We all talk about the acceleration of climate change in its impacts that we’re observing. One sees the incidence of wildfires going up more rapidly than people expected, the incidence of heat waves and droughts going up more rapidly, sea level is rising more rapidly… All of these indicators are moving more rapidly.
Wrong on all counts. It’s simply impossible for Holdren to be honestly mistaken here, because the data in some cases comes from US government agencies. Consider sea level rise. There is not the slightest evidence that “sea level is rising more rapidly”, that this represents an “acceleration of climate change in its impacts”. When Holdren says “One sees…” he cannot mean to ‘foresee’ as a ‘seer’ might do, since his previous statement makes it clear that this is one of the accelerating ‘impacts that we’re observing’. Well, it’s really very easy to determine Holdren’s integrity since we can simply look at the data that ‘we’re observing’. Do records show that sea level rise is accelerating, “rising more rapidly”? Not at all: sea level rise has been pretty steady over the last 100 years, except in the last few years when it has appeared to slow down significantly, even to the extent of appearing to show a declining trend since 2006. Wolfgang Scherer, Director of Australia’s National Tidal Facility correctly states
One definitive statement we can make is that there is no indication based on observations that sea level rise is accelerating.
