Definition: Barber Event

May 9, 2015

A monumental climatic event is unfolding before our eyes this year.  The ramifications will affect entire human race, nay, the entire community of Gaia dwelling souls.

 David Barber, 21st Century Arctic Explorer, has been warning us for years, but too many of us have been blinded by our greed for oil and money.  The Arctic will go completely ice free this summer.  This will no doubt force polar bears into extinction and set off a globe spreading chain reaction of extinction and desolation.

This extraordinary occasion deserves its own geological name.  I propose we call it the “Barber Event.”

Here is what will happen to Arctic sea ice…

Arctic to be ice free within four months


When was the last time this happened?

August 4, 2013

We are in the middle of the Arctic melt season.  The rate of sea ice melt is at it greatest from about mid-June (day 156) to about mid-August (day 216).  Thirty years ago, according to satellite data, the arctic lost about 5 million square kilometers of ice during this period.  For the last decade the arctic has lost closer to 6 million square kilometers of ice during this period.  That averages out to about 100,000 kilometers per day.  Of course, it recovers all, or most, of that area during the freezing season.  This point is illustrated in the follow image from Cryosphere Today (8/4/13, with my annotation).

Now look closer.

Notice that for the last 10 days there has been no drop in sea ice area. We would have expected a loss on the order of one million square kilometers!  Either something extraordinary is happening, or there is a problem with the satellite data.

When was the last time this happened this time of year?  This image shows the entire history of the arctic (which everyone knows really means back to 1979).  This is “unprecedented!”
