Albedo effect from weaker magnetic field

Read an article recently, probably Zerohedge, but not looking for it.  Basically it said there is a nuclearization of the cosmic rays that makes the sky opaque causing the albedo effect, much like sunlight on snow. More cosmic radiation from a weakened magnetic field.   All happening with a little ice age from lower sunspot energy.  There will be migration south because of this combined event.  A little sketchy on the timing.

I am confused about your statements but will guess that you are referring to GCR's. Galactic Cosmic Rays.

They act as condensation nuclei for moisture in the air to condense out on. The more of them in the atmosphere, the more clouds(which block warm short wave radiation from the sun)

When we have an active sun, the solar wind is stronger and it deflects alot of the GCR's, which means less cloudiness and a warmer the theory goes.

When we have a quiet sun, the solar wind is weaker and it allow more GCR's to penetrate our atmosphere and cause more cloudiness that blocks the warming sunshine.

The sun was unusually active during the last century, which caused less cloudiness and some warming. It started getting less active around the start of this century. 

How powerful will this change/effect be?

Oceans hold 1,000 times more heat than the atmosphere, so if this affect is cooling the planet, there is still alot of stored heat from the previous century from an active sun that is coming out of those oceans. 

Some speculate that the Little Ice Age that occurred during the Maunder Minimum in sunspots were correlated/caused by this affect.

We are living in sort of an experiment right now with the low sunspots and atmosphere that can be studied with technology and gadgets that can measure things that were never measured before during the last time this happened.

Of course its impossible to tell how much of the warming was caused by CO2, but its reasonable to believe that at least half of it........since we have been unable  to distinguish a CO2 vs natural fingerprint in the atmospheric warming.

Maybe, if the suns behavior is extremely weak for another cycle, it can help to understand that part of the natural cycle that is contributing to warming/cooling and this will assist in understand how much of the warming has been coming from CO2, which would help to adjust climate models so that they don't continue to all be too warm.

The Maunder minimum and the Little Ice Age: an update from recent reconstructions and climate simulations

You can find several articles like this one:

Astrophysicist – Mini Ice Age accelerating – New Maunder Minimum has started

This guy is actually pretty sharp but his views are controversial and speculative, so I wouldn't put any stock in him..............or anybody that's predicting another Little Ice Age.

Greenhouse  gas warming from the increase in CO2 will likely help to insulate us from dangerous global cooling induced from the affects of the sun. .........and global cooling is what would actually cause harm to life on this planet, not the beneficial warming thats been happening

I am assuming that a polarity reversal is going on.  Since this event takes from 300 years to 1500 years, maybe you need decades of the magnetic North Pole moving 8 miles/year before you will acknowledge that this event is underway.  More cosmic radiation reaches the surface when the magnetic field is weak which occurs during a reversal.  This radiation causes dramatic increase in cataracts in both people and animals as well as melanoma tumors.  It is this radiation that causes the atmosphere to turn opaque.  Mike, you are saying that the low sunspots reduces the solar wind which would sweep this radiation aside.   I am saying that the reduced magnetic field is letting more radiation into the atmosphere.  So two separate things are occurring simultaneously.  And I think whatever happens will be enhanced because they are happening at the same time.  No one knows what will happen because man was not around the last time these two events happened simultaneously.  Stay flexible.

Thanks Lacey,

Sorry that I misunderstood what you were saying the first time but I get you now.

You are right that this would be uncharted territory since humans have existed and the affects are very much unknown.

I was studying this several years ago but lost interest. Thanks for bringing it up again as there have been some profound changes recently:

Earth’s Magnetic Field is Acting Strange – Scientists Aren’t Sure Why

"The key question remains the same — why the magnetic field is changing so dramatically. The possible reasons for the geomagnetic pulses are ‘hydromagnetic’ waves arising from deep in the core and the move of the magnetic pole could be connected with a high-speed jet of liquid iron beneath Canada."

This could have huge affects to life on this planet!

The way that so many creatures on this planet use the magnetic field to navigate is incredible by itself.

The Earth’s Magnetic Poles Are Overdue for a Switch

But this time, it will spell disaster for our electrical infrastructure.

Electronic Nightmare

"The Earth’s magnetic field protects the planet from solar and cosmic rays. When the poles switch, this protective shield could diminish to as little as one-tenth of its typical ability. The switching process could take centuries, and the entire time, radiation would be able to get closer to the planet than usual.

Eventually, this radiation could reach the surface of the Earth, rendering some regions uninhabitable and causing entire species to go extinct. Before that happened, though, a weakened magnetic field would likely impact orbiting satellites, which have suffered from memory failure and other damage when exposed to such radiation in the past."
