Confirmed! – Geomagnetic reversals can trigger glaciation – Ice Age Now

Posted by M. C. on July 11, 2019

Bomb-shell press release from Kobe University confirms what I’ve been saying for years, that geomagnetic reversals can trigger ice ages – perhaps almost instantaneously. I’m not sure that was the intent of the press release because it doesn’t actually use the words “ice age,” “trigger ” or “instantaneous,” but that’s my take on it. See if you agree.

With a title that belies its importance, “Winter monsoons became stronger during geomagnetic reversal,” the press release (see full release below) explains that galactic cosmic rays (high-energy particles from space) increased “dramatically” during the Matuyama–Brunhes magnetic reversal of 780,000 years ago. Such an increase (called the Svensmark Effect) could induce more low cloud formation and influence the Earth’s climate via the umbrella effect.

That increase in galactic cosmic rays came about, the press release explains, because the Earth’s magnetic-field strength plummeted to less than 25 percent of today’s. In-as-much as our magnetic field shields us from cosmic rays, and in-as-much as geomagnetic field strength is now declining rapidly ( 5 percent per decade ), and in-as-much as we may be headed for a reversal right now ( here ), this discovery concerns me ( and also here ).

As  I mentioned earlier, the press release doesn’t actually use the words “ice age.” What it does say, however, is that geomagnetic reversals correlate with sea-level changes.

What causes sea-level changes? Sea levels decline when water accumulates on land as ice, forming giant ice sheets sometimes more than a mile thick. Then, when the ice melts, sea levels rise once again. Changes in sea level therefore imply glaciation. (Sea levels stood at least 400 feet lower than today during the last period of increased glaciation.)

Just to be fair, even though the press release doesn’t mention it, the underlying paper does mention both glaciation and iceberg discharge. Kind of hard to get iceberg discharge unless there’s some glaciation going on.

As far as I’m concerned, this is enough by itself to show that geomagnetic reversals correlate with ice ages.

Even more worrisome to me

Even more worrisome to me, though, is the following statement almost buried toward the end of the press release: “Added to other phenomena during the geomagnetic reversal – evidence of an annual average temperature drop of 2-3 degrees Celsius.”

Let that sink in for a moment. An annual average temperature drop of 2-3 degrees Celsius.

Do they really mean that average temperature dropped by 2-3 C every single year? I’m not sure they do. I may be interpreting it incorrectly, but if that is indeed what they mean then we could be in for a very rough ride.

Many people think it takes hundreds, if not thousands of years to descend into an ice age. But as I warn in Not by Fire but by Ice, ice core studies show that our planet has sometimes switched from periods of warmth such today’s – such as today’s! – into full-fledged glaciation in less than 20 years…

Be seeing you
