And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Glaciar Perito Moreno in Patagonia Argentina. Up until 5 or 6 years ago it was the only non-receding glacier in the world. Now it is receding like every other glacier in the world.
Climate Change And Growing Glaciers: A Complex Story
Glaciers are literally big, moving ice cubes. If you keep them exposed to above-freezing temperatures (or hotter) then they will melt at a rate relative to the surrounding temperature. For this reason, glaciers are universally regarded as being the indicators of the severity of global warming and climate change in any given place where glaciers are present, essentially the global climate equivalent of "canaries in coal mines".
It’s a startling fact that no one can afford to ignore that a staggering 90% of glaciers and ice fields worldwide are in retreat due to a rising surface and atmosphere temperature, an effect which is particularly bullying the Arctic region at this time. But rest assured, in fact be astounded to learn, that some glaciers are either holding a steady position, or, even more surprisingly, have been advancing at greater rates than even before climate change became noticeable.
But hold it! Before you run out and barge into the nearest newspaper editor’s office or post on Tumblr about how climate change really is a hoax invented by anti-oil and fracking coalitions, glaciers don’t necessarily advance due to cooler temperatures. and in this case, they aren’t. At least not really. What is happening with these select and lucky few is that climate change has caused an increase in precipitation, which of course in the winter comes in the form of heavy snowfall. And so you understand exactly how that is possible, let’s take a quick look at how glaciers are formed in the first place: Snow falls heavily on a mountain through the winter, but never completely melts during the year, so more snow falls the next winter over the first snow field. This exact process gets repeated at least 5 to 10 times consecutively, and the increasing pressure of the refrozen snow then causes the mass to slide or sink downward, and just like that a small glacier or other ice-mass is formed.
There is clear evidence now that climate change is not a single, basic event affecting the world uniformly, but instead is a series of micro-climate changes, working their effects in different and fascinating (yet terrifying) ways. Now, let’s take a closer look at some of these growing glaciers (at least the most notable ones), where they are, how much the increased precipitation is affecting them, and any impact their advances are having on their local ecosystems, for both the good and the bad.
Well I know that 10,000 years ago ( a blip in time really) right here where I sit the ice was over a mile deep. Someday it will be again. The ice comes and goes. We are still in an interglacial period and that's a good thing for us. All civilization has developed in this short time span.
Me to. There's a number of humungous rocks sitting around here in NH that ice age left behind, it left behind enormous gravel beds, nicely graded by size. Escards I think they are called.
When the snow makes it through the summer at Sandy Lake (Saskatchewan) Canada, I'll be concerned about an ice age coming.

ReplyDeleteIce age is certainly not alive anymore
