There is an old joke that goes "why do women have poor depth perception? A: Because men tell them [holding two fingers very close together] that this is six inches."
I am kind of reminded of that joke here, where the graphic on this eco-catastrophist page shows a 3-foot sea level rise engulfing the botton half of San Francisco’s Transamerica building (hit refresh if you don’t see anyting happening on the top banner). Even the moderately catastrophist IPCC shows less than half of a meter of sea level rise over the next 100 years, not three feet.
By the way, memo to environmental activists: If you want to sway middle America to your cause, complaining that global warming will flood San Francisco may not get the results you want. HT: Tom Nelson
