In Northern Hemisphere, Melting of Polar Ice Well Ahead of Many Predictions – Next Month Could See Ice-Free Arctic

There’s an old saying which some believe originated as a Chinese curse:May
you live in interesting times.The new millennium certainly qualifies! It
often seems that the weather has become our worst enemy. If I were a polar bear,
I know that I’d feel that way.

So far this month, I’ve been telling you about the significance of proclamations
about global warming which have emerged from the scientific community this year.
The news is not good. In fact, it’s horrible. All peer-reviewed predictions
about the causes and effects of global warming are coming to fruition and it may
well happen that next month, summertime melting of polar ice in the Northern
Hemisphere will be complete. We could have an ice-free Arctic for the first time
in the history of humankind.
That’s a very big deal. In fact, some of the more conservative estimates by very
respected academic bodies gave us until 2050 before we’d see a completely
ice-free Arctic, even in summer. They were way off. Why? Was there a flaw in
their interpretation? Could it be that atmospheric carbon content is not the
best measure of the doom we have leveled on ourselves?
