Geldof The Lame

Aging British musician turned activist Bob Geldof recently gave a speech in Johannesburg in which he said global warming would kill us all by 2030. Now I know Geldof is not a climate scientist (and wears his sunglasses indoors too boot) so maybe he deserves a little leeway but if he really truly believes his own claim that climate change will kill the entire human race in 17 years he ought to consult a mental health professional. According to a Berkeley physicist, Richard Muller, who started an organization (Berkeley Earth) to exhaustively examine worldwide temperature trends, the average world temperature will increase one degree Fahrenheit by 2030. How big a change is that? Well, it's like moving from Harrisburg, Pennsylvania, where the average midsummer daytime high is 85 degrees, 40 miles south to Gettysburg, where the average high is 86. Surely Geldof doesn't believe the current residents of Gettysburg are all dying of drought and heat prostration. So why would he believe the residents of Harrisburg will all start dying off if summer highs go up one degree in 17 years?
