I’m sure you haven’t missed the regular press articles over recent months and years, from reputable sources, telling how this process is a sign of the end for all of us. In case you haven’t check out this or this or this. This harbinger of impending doom is supposedly all our fault, and we are supposed to spend gazillions of $$$ in attempts to stop, or pause, the process.
This is something humanity has never seen before, at least not in anyone’s living memory, but the question is: – “Just how ‘permanent’ is the permafrost?”
Is it 6,000 years – as we’ve been told by the house of Ussher (when the world was created)? Or is it longer?
Turns out that it is much longer than 6,000 years, but it’s certainly not forever. Scientists already know that the North Pole/Arctic was completely ice-free around 110,000 years ago – during the prior inter-glacial period. Why did it occur then? I think I can be very confident in stating (although I wasn’t around then) that it was not caused by Industrial pollution or farting cows ie: Us. Note that this “news’ does not get any airplay.
The reality as we now know is that Planet Earth has never had a stable climate, but (geologically-speaking) regularly cycles between hot and cold. In recent (again, geologically speaking) history, this occurs roughly every 80,000 – 100,000 years. The last Ice Age peaked around 20,000 years ago, which means we are about 20,000 years into an expected 50,000 year warming cycle. Get used to it. In my opinion Global Warming is perhaps 25% at most anthropogenic in origin.
Perhaps we should be calling it the “longtime-frost” instead? But I guess that would not generate such catching headlines and interest from all concerned. Nor would we be attempting to stop it: – We have yet to learn to control other facets of Mother Nature’s antics such as typhoon, volcano or earthquake, so how on earth can we expect to reverse another of her regular outbursts?
There is no doubt that the longtime-frost will continue to melt; that sea-levels will rise as a result, and Arctic habitats will be considerably changed for many, many years, but it’s time to stop yelling about it, and start thinking as to how we can assist those countries and species that are definitely going to be impacted.
There is no doubt that the littoral nations of the planet will need to spend considerable sums to literally shore themselves up. As a follow-up, ask yourself ‘what happened to the polar bears last time this happened:’ – they obviously didn’t go extinct – like so many frontline activists in this arena are asserting that is what is going to happen to them as a result of this change of climate.
