Yet another thing to be afraid of

by Greg Krehbiel on 28 January 2014

Forget global warming, worry about the MAGNETOSPHERE: Earth’s magnetic field is collapsing and it could affect the climate and wipe out power grids

The article is overly dramatic, but it’s true that the earth’s magnetic field flips from time to time (so the geologists tell us, based in part on analysis of rock in the sea floor), and it’s hard to know exactly why or when. Some people say we’re overdue, but they don’t really know. These things aren’t on a schedule that we can determine.

IMO it’s just one more crazy, chaotic thing that affects life on this spinning ball of rock, and it’s another of the reasons I’m skeptical of any predictions about future climate.

Sea levels rise and fall. Temperature goes up and down. Rivers change course. Rain forests turn into deserts and vice versa. Plants and animals go extinct. There is no “normal” that we can count on or try to preserve.

    I am on the exact same page as you – shit happens. Good, bad, indifferent, change happens and most of the time it is out of our control. Remember the doom and gloom of Y2K? Networks would crash – businesses would collapse and then……nothing. The world is getting warmer, now it’s getting colder (though still caused by “warming”, go figure). The press makes a living out of trying to scare people.

    Yes. That’s the point we must always keep in mind.
