I’ll Take Mine On the Rocks, Please

Among non-geologist members of the public there’s a  fascination with glaciers and a deep, almost reverent mystique – a sort of atavistic, prickling-behind-the-neck connection with the Ice Age. In Europeans, it seems to be more a vestigial connection – a sort of cultural memory. Perhaps it’s why the western populace is so consumed with the idea of man-made global warming and theArctic sea ice (non-existent but perpetually hyped) loss of polar ice which people seem to view as the last remnant of the ice age, which was the back yard of European pre-history.

Whenever someone asks me a geology question – this typically only happens when we are on a weekend camping trip or something similar – they almost invariably interrupt my explanation at some opportune point and ask if what I am telling them is related to “the glaciers”. In most cases what we are discussing is not even remotely associated with glaciation.

I understand the connection. The first nip of real autumn in the air stirs something in some little recess of our northern cultural memories and we feel a connection to our ancestors. I think it is one of the reasons most of the global warming alarmists live in high latitude areas – you don’t hear many people from the tropics screaming about the loss of polar ice – except to get money from some global warming based scheme (I’ll explore the Maldives a little below). Eur-Asians are varieties of the human species with an evolved circadian link to a seasonal way of life. It is the rare person who chucks northern life with all its harshness and wild temperature and precipitation swings, to move to more moderate climate in a lower latitude. Retirees don’t count – these are people whose testosterone and estrogen productions have waned which seems to make them more reasonable specimens of our ilk and suppresses the relentless, mindless drive that keeps the rest of us soldiering on in the face of the harshest of conditions for at least half of each of our few years on Earth.

If it sounds like rubbish to you, ask yourself why any Swede, or German, or Norwegian, or Scotsman, or Canadian (all countries with very strong ‘stop global warming’ activists and organizations) or Minnesotan, wouldn’t jump up and down, wave a banner ancave man cartoon 2d shoot off fireworks of celebration if future winters were to be a bit less severe, a bit shorter and the growing season consequently extended just a few extra days.  After all, those WERE the condition a thousand years ago, during the Medieval Climate Optimum. There were thriving agricultural communities in all those countries – even in Greenland where an active viticultural concern was thriving – despite the absence of modern farming and chemicals.
Now those countries all have severe winters with comparatively shortened growing seasons (Greenland has NO growing season now). But tell them that things might warm up a bit and they let out a collective yelp of fear and alarm you can hear at land’s end. I can think of no better reason than we northerners are clinging to some sort of suppressed, ice-age cultural remnant, and we retain a sort of perverse fascination with freezing.

Of course what the global warming are being told is that the hypothetical increase of temperature over the next century will result in a rise of sea level of a meter or two, which would submerge many populated areas.

Is that true? Well, the only thing we can do is to look at the evidence to see if that is what happened the last time the Earth was warm. What was sea level during the Medieval Climate Optimum? Or the Roman Warm Period? Pretty much what it is now, really. Where were the deserts then? Pretty much where they are now. And so on.sea level

Now this sea level rise thing is really interesting. Places like the Maldives are claiming that the sea level rise caused by anthropogenic global warming (AGW) is drowning their archipelago. It is true that sea level has been rising – pretty much since the end of the last glacial maximum (14,000 years ago), since which time it has risen about 130 meters (that’s about 400 feet). Recent measurements show a definite slow down in the rate of the rise, however.  As a final note on this little charade, four new airports are being constructed in the Maldives – if they are afraid of being submerged, why are they spending hundreds of millions on new airports?

Now there are twosea level causes of island submergence – sea level can actually rise – or the island(s) could be sinking, which is a very common thing among oceanic islands. One thing is certain – there is NO evidence that sea level rise was/is caused by AGW – especially because atmospheric temperatures have decreased slightly in recent years and sea surface temperatures have not increased.

Moreover, there are now MANY published papers regarding the supposed loss of polar ice, which has actually increased in extent and has been increasing in thickness and mass for the past few decades.polar ice

Anyway, in the absence of some sort of cultural memory of our pre-historic, ice-age human ancestors, I am at a loss to explain the fear people have that the Earth might be coming out of one of the coldest periods in its history and becoming more like it has been for most of its history; i.e., warmer than it has been these past several million years. Based on the science – the real science – it doesn’t look as though we should expect any change very soon, however.

Personally, I love winter and I admit to the lure of the Pleistocene, and the sight of musk oxen, or wolverines, American bison, caribou and other arctic to sub-artic megafauna stirs some sort of deep rumblings of the Pleistocene in us.

Gotta go now, I feel the urge to embed some sharpened sticks facing upward at the base of a cliff.
Well, perhaps I’ll just settle for a glass of scotch. Of course, I’ll take mine on the rocks, please.
