INTRODUCTION

There’s a kind of doomsday feel to things right now - have you noticed? It’s not just that the Mayan calendar runs out on December 21st of next year. It’s not even the plethora of new warnings from astrophysicists, doctors and geologists about the possibly catastrophic events that are now known to be on the not-too-distant horizon. It has more to do with the zeitgeist, an undifferentiated sense that things can’t go on like they are forever.
And, of course, there are clues. Almost daily, items half-buried in news reports point to the Doom scenarios just lurking around the corner. Maybe you are too busy or too trapped in denial to notice them all, so this blog is here to help you keep track.

Something to Worry About Today

Wouldn’t you just know it? Here we are, cringing at the thought of the horrors that unchecked global warming might have in store for us, and the scientists come up with yet another Doom scenario to keep us awake.

Bill McGuire*, of the Aon Benfield Institute at UCL, has revealed that the melting of ice caps can do more than just flood us and possibly release methane clathrate gas to superheat the atmosphere.

It can cause earthquakes, tsunamis and volcanic eruptions.

The ice layers at the cold ends of the Earth are kilometres in thickness. But even that depth isn’t secure.  Recent studies show that thousands of metres have already been lost, bringing harmful gases that much nearer the surface.  Worse still, these ice deposits have been holding in check large areas of rock, including entire mountain ranges. When they break free of the ice, they create earthquakes and expose the superficial parts of the magma that explodes in volcanoes.

Next time you leave the lights burning too long or plan buying a large engine car, consider how the ground may be shifting under your feet.



*In our book, The Coffee Table Book of Doom, we erroneously referred to Bill McGuire as Ben. That must be because of the proximity of his name to Benfield. For that blunder, we most humbly apologise.
