Aint that a hoot!

The International Ice Charting Working Group released a report and this great map which shows a shrinking arctic ice cap.

In September 2007, the Arctic sea ice reached the minimum extent – the lowest amount of ice recorded in the area annually – in the history of ice charting based on satellite, aircraft and surface observations, continuing a recent trend of diminishing sea ice that began in the 1980s and has accelerated. While there will still be natural inter-annual variability, the decline is likely to continue,” the statement reads.

Understand, “the history of ice charting began in the 1980S.” Prior to the 1980s, we don’t officially know the history of the ice cap.

Mow, let’s revisit the Arctic Ocean model referred to by Robert H. Essenhigh, he E. G. Bailey Professor of Energy Conversion in the Department of Mechanical Engineering, Ohio State University. He writes

So the model we now have is that if the Arctic Ocean is frozen over…the existing ice cap is not being replenished and must shrink, as it is doing today. As it does so, the Earth can absorb more of the Sun’s radiation and therefore will heat up—global warming—as it is doing today, so long as the Arctic Ocean is closed. When it is warm enough for the ocean to open…then the ice cap can begin to re-form.

As it expands, the ice increasingly reflects the incoming (shorter-wave) radiation from the sun, so that the atmosphere cools at first. But then, the expanding ice cap reduces the radiative (longer-wave) loss from the Earth, acting as an insulator, so that the Earth below cools more slowly and can keep the ocean open as the ice cap expands. This generates “out-of-sync” oscillations between atmosphere and Earth. The Arctic Ocean “trip” behavior at the temperature extremes…was originally estimated at about 500 years, then reduced to 50 years and, most recently, down to 5 years (Calder, N. The Weather Machine; Viking Press: New York, 1974.). So, if the ocean is opening right now, (and it is) we could possibly start to see the temperature reversal under way in about 10 years.

Bottom Line: Instead of being on the edge of extinction from high heat and rising seas, we MAY be on the edge of the ice age predicted by scientists back in the 1970s. Aint that a hoot!

  1. Wow that is a hoot! I also think it’s a hoot that the Intergovernmental Panel on Climate Change (IPCC, Created in 1988 by the World Meteorological Organization and the United Nations Environmental Programme.

    In their “most recent assessment, IPCC states unequivocally that the consensus of scientific opinion is that Earth’s climate is being affected by human activities: “Human activities … are modifying the concentration of atmospheric constituents … that absorb or scatter radiant energy. … [M]ost of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”.”

    At the rate of global warming, how much damage will occur before this so-called Ice Age starts getting revved up?

  2. [M]ost of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”.”

    Same old crap!

  3. I don’t think it is a hoot.

    I think I would rather try and survive in a warmer climate where food grows. I think it is a forgone conclusion that food does not grow so well in ice.

    When Nancy Pelosi returned from a trip to Greenland last spring, making the statement that she saw proof of climate change, I wondered if she thought it was now her responsibility to take steps to stop the climate change.

    Too bad she and Al Gore weren’t around for the Vikings. I might be wrong on my history, but I think when the Vikings first settled Greenland a little over 1,000 years ago, farming and therefore a means of existance was possible with the warmer climate.

    Not long after settlements were established the climate turned colder, eventually negating the possibility of growing crops for feeding both humans and animals.

    Sounds like a miserable slow death to me. Slowly starving and being cold at the same time. YUK!

    But on the other hand, I wouldn’t want to get locked inside my greenhouse in the summer. Lots of tomatos and cucumbers in there to eat, but I sure would get hot and sweat a lot.

  4. It woyuldn’t be a hoot, you’re right, to live in it. There would be a mass movement south, across the border into Mexico to find shelter and work and no health care.
