NEW ICE AGE ABOUT TO BEGIN

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.

  1. John, I was citing the 10m elevation from memory. So I just looked, and see that the airport is officially 12 meters. But if all the water at the polar caps were to melt (it won’t) the sea level would increase by 60m. Warming has a tipping point. Historically, after it is reached, cooling begins. This is a normal part of the carbon-oxygen cycle, which is wonderfully explained here:

  2. My geology class in school said 860 feet more would be covered if all of the ice melted. We are in a ice age now. The normal condition of our planet is no ice in a year round state, this is the case for 99% of earth’s history. Those inland seas that are featured on the geology maps of earth’s past, those are the normal state of our planet.
