1989 Shock News : 12 Degrees Warming And 20 Feet Of Sea Level Rise By 2050

Doug MacAyeal, a geophysicist at the University of Chicago, has been developing a computer model to predict what might happen in the south polar region as a result of an increasing greenhouse effect, and expects to be able to make some accurate predictions on sea-level rise this summer But it is possible, he says now, that Antarctic warming could be as much as 12 degrees F in the Antarctic 60 years from now. And that, he projects, would be enough to detach the West Antarctic sheet, with a resulting water-level rise of 20 feet.

Let’s hope not. The far more conservative estimates of sea-level rise that most authorities project—say approximately five to seven feet

  1. 12 F by 2050 ? So today after 24 years or half way we should be at 6 F higher in Ant. ? Why then is the ice mass expanding to record levels and the temp dropping? Settled science they say. Act now they scream. These losers have nothing in common with science – Quackitists and Quackademics.

    Conservative estimates of 5-7 feet over 60 years from ‘most authorities’? OK. Let’s entertain that thought and say 6 feet in 6 decades. So where exactly do we find 2 feet of sea level rise over the past 2 decades? So much for their ‘authority’.

    When will we ever discover just how many wrongs it takes to make a right?

      Spot on Gator. At best they might have 21 mm across the past two decades, and even then its very difficult to prove definitively. Out by a factor of 30.

    One critique of Doug, from ‘ratemyprofessors.com’…

    “An average third-grader could probably get an A in this class. Doesn’t seem to know anything outside of actual physical science although course integrates biology and archeology. Shows Tomb Raider clips instead of teaching. Class is a waste of my life.”

    Seems that his class is either well liked, or described as an easy A. I remember those profs.

    That would be very nice. People have always thrived in warm times. But unfortunately its another false promise from the liars. People always suffer when its cold, and we are obviously headed for more cold. The current sun cycle is way, way, below normal.

    • R. de Haan says:

      Nothing to worry about. This happened many times before. with our current level of development we’ll survive. Love to have the old winter back.

    And now we have to contend with “SUPER” typhoons …

    WTF is a “SUPER” typhoon?

  6. Karl W. Braun says:

    The Philippines has a history of storms snapping off coconut trees at their bases.

  7. Your title is misrepresentative. Read what he actually said. He says warming by 2050. He does *not* say 20 feet by then. Obviously he was not talking about an instantaneous loss of the entire ice sheet, but rather about a threshold being crossed where the *eventual* near complete demise is locked in.

    • Andy Oz says:

      “But it is possible, he says now, that Antarctic warming could be as much as 12 degrees F in the Antarctic 60 years from now. And that, he projects, would be enough to detach the West Antarctic sheet, with a resulting water-level rise of 20 feet.”

      Perhaps English isn’t your first language Aslak. Steven’s headline is correct.

    • R. de Haan says:

      He’s recycling old news. There is no sea level rise and no ice caps melting.
      Just live a happy life and forget about the alarmist scare mongers.
