Mother Earth ups the ante

Mariner has harangued his readers about the Armageddon consisting of excessive population, disappearing natural resources, global warming and uncontrolled AI. But Mother Earth has just started to get involved.

In a report from Nature Geoscience –

“North America’s geological core has persisted for billions of years—it’s what scientists call a craton, a massive block of continental rock that withstands the natural recycling system of plate tectonics. Typically, scientists think of cratons as unchanging, nigh on eternal. But new research published on March 28 in Nature Geoscience suggests that a long-lost geological plate may be siphoning rock from the bottom of the North American craton, eroding it from below, right under our feet.

Such a scenario would not be unprecedented—scientists have evidence that the North China craton thinned dramatically millions of years ago—but it would certainly be surprising and intriguing to study in real time. “Cratons are the oldest cores of continents, so they have been sitting near the Earth’s surface for billions of years,” says Claire Currie, a geophysicist at the University of Alberta, who was not involved in the new research. “They’ve persisted through time, so this is quite unusual.”

Mariner could find no projected dates for these events but at some point in the future, the next tectonic shift may turn the Mississippi River into the Mississippi Sea or conversely, The Mississippi Mountains.

Mother Earth’s stash seems unending. Much of Florida and much of the Gulf-facing land in the US will disappear under rising seas; Global warming will disrupt political, economic and environmental conditions that may cause even more famine and unrest among human populations.

Mother Earth wants everyone to know that AI isn’t the only player in the future of us Homos.
