That, on the other hand is disputable. Would have it melted away, would have been it nurtured by temperatures that would have been slower than today or would have been it maintained as it was, hard to tell (there are ancient glaciers more than 20 000 y old)
Why would it be disputable? The existence of ice on this planet is a geological anomaly. Only the polar regions themselves offer conditions naturally conducive to low temperatures (due to a lack of solar exposure).
More than 90% of all glaciers that have ever existed disappeared long before the age of industrialization, almost 80% even disappeared before the anthropocene. I myself dwell in a valley that used to be covered by a glacier until about 5,000 years ago.
A region so far down south as the Alpine Belt wouldn't have ever been covered in ice if it wasn't for the so called Ice Age. (cont'd)
What is sure is that a bunch of glaciers are melting right now at an accelerated pace
Yes. Even though the melting of the glaciers in Switzerland has somewhat lessened as of late, and a couple of individual glaciers even grew due to two heavy winters.
Well, the decisive question that is never asked nor given: What does it matter? Please bear with me here.
Strictly speaking, those glaciers are only important as reservoirs of drinkable water. They do not serve any other purpose. Which, as I put to you, begs the question: Why aren't we prepared to deal with their disappearance? For they're invariably going to disappear, and would've had done so even without human interference.
Now, I'm certainly not advocating an attitude of "après moi, le déluge". There's plenty of reasons to fight climate change where it can be fought.
And yet it strikes me as odd we're so focused on trying to stop the unstoppable instead of spending any thoughts whatsoever on how to mitigate its consequences. For instance, why are we so hell-bent on trying to save a bunch of geologically untenable islands (don't even get me started on that "act now or swim later" nonsense courtesy of Greta).
The sea levels are rising naturally since we're in the process of leaving the pleistocene glaciation; all we've done is speed up the process. And yet, one could walk from France to England dry-shod perhaps as little as 9,000 years ago.
The Maledives, for example, would've become submerged
anyway. So why don't we use our wealth trying to either raise them (which is actually possible) or finance the resettlement of their inhabitants instead of continuing to pour money into schemes that have showed little effect so far?
The point I'm (incompetently) trying to make here is this:
It seems to me the primary reason behind the phenomenon of climate change denial is the abscence of any open-ended debate about what it is we want to achieve.
We live in democracies, and such being the case you do not get to force me to accept your solutions only on the grounds that the clock is ticking. I'd be perfectly entitled to the opinion that my taxes shouldn't be used to build wind energy farms, but give out free air conditioners to every household.
Secondly, it seems to me the primary motivation of the average climate-change activist is an unduly romantic idea of nature. That Greta Thunberg? Even the worst-case scenario for her home country of Sweden for the intermediate-term future is a climate roughly equal to Germany's current climate.
I'd tell Greta that, despite all my bitching about the hot summers we've been getting, the climate here is nothing to be fearful of. The point being, that broad and her minions are driven by – well, partially by human longing for the apocalypse (it gives purpose) – the idea everything needs to stay as it is. But that's not the default on this planet.
