Climate change is real, and deadly serious. Geological history tells us that we have surpassed a tipping point, of parts per million of carbon in the atmosphere. This is causing the Greenland ice shelf to melt, as it has in the past. Soon, the Atlantic conveyor, which is the “outbound cycle” driving the cold, heavy meltwater south beneath the surface of the Atlantic Ocean all the way past South Africa, will shut down suddenly. Without meltwater, there is no more convection to move the water of the Gulf of Mexico north – no more Gulf Stream. A new ice age will begin, not unlike the last one which flash-froze Siberian elephants. These critters are still being found, with tropical vegetation in their gut.
The evidence of this melting event is upon us, and documented with breath-taking photography, by a daring cameraman (who is a former climate change skeptic), and crew, from National Geographic. Watch the movie trailer at youtube. (Early notices at RottenTomatoes gives the film 96%.) Then find yourself some new digs in a warm location, which isn’t too near a low, coastal setting. Sell your beach frontage before it’s underwater! Remember Hurricanes Katrina, and Sandy! (In case you were wondering, Merida centro is about 40 kilometers/25 miles from the coast; and the airport elevation is about 12 meters/39 feet.) Maybe some day Merida will be a Venice of the New World? Not likely in this century; but across the Gulf in, say, Miami, maybe so.
+ For those who want to understand the science and history of this cycle, I highly recommend an easy book by a great storyteller who happens also to be a science journalist with a PhD from MIT – SCATTER, ADAPT and REMEMBER: How Humans Will Survive a Mass Extinction.
