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


          The tundra is on fire. And we’re next, say the scientists.

          In 2007, lightning struck the Arctic tundra at a place called Anaktuvuk, setting it ablaze.  This was formerly impossible, because the mixed lichen and very hardy plants were always too moist to burn. But global warming has helped dry out the frozen landscape, leaving us perilously close to a thaw that will send enough greenhouse gases to heat up the world to terminal levels.

          Beneath the permafrost in the polar wastes are enormous deposits of methane and other forms of carbon. If the melt continues, the accumulated gases may drive up Earth’s temperatures at an unsustainable (and unstoppable) level.

          The fire at Anaktuvuk released more carbon in a single go than is emitted in two years by a city the size of Miami.
         So, please: no more jokes about flatulent cows.
