In my recent post on The Cosmogenic Isotope Record and the Role of The Sun in Shaping Earth’s Climate an interesting discussion developed in comments where there was a fair amount of disagreement among my sceptical colleagues. A few days later, retired Apollo astronaut Phil Chapman sent me this article which lays some of the doubts to rest. Phil never got to fly in space but was mission Scientist on Apollo 14. It is not every day I get the opportunity to publish an article from such a pre-eminent scientist.
Cosmic Rays, Magnetic Fields and Climate Change
The N magnetic pole used to lie in northern Canada, but not any more.
Very interesting link in the article:

Wow! You’re right. The magnetic pole after loitering around the Boothia Peninsular for ages is moving close to 60 km per year and has left Canada. So much for declination listed on maps.
When I first went to Greenwood, Nova Scotia, the main runway was 09-27, then it changed to 08-26 and is now 07-25 – those are magnetic headings to the nearest ten degrees. The North magnetic Pole really is on a roll since nobody moved the runways!
From that link…
“world population will reach 11.2 billion, 50% more than now”.
“Giving [the world] a standard of living comparable to that … in the United States would require [an increase] in the world GDP by [5.4 times]”.
Get your GDP while you can!
Reverting to another 100,000 years of glaciation is of no concern but the prospect of an interim minuscule increase in temperature due to an increase in greenhouse gases well within the natural historical noise is now the paramount sanctity of the green theocracy that rule over us. The return to serfdom will still require a more complete dumbing-down of society than has yet been accomplished through public education despite great cost and obvious progress at doing so.

You need to change the amplitude scale of your heat chart’s vertical axis … THEN the problem will LOOK enormous!!!!
Or use 10-shades brighter RED on your weather maps. Then you will SEE with your eyes how the planet is BURNING UP !
We’re gonna get blamed then taxed on this, aren’t we…
“The return to serfdom will still require a more complete dumbing-down of society…”
Jeez, that’s a scary thought.
Not only is the magnetic field important in the control of cosmic rays, it is quite possibly directly integrated into the shaping of the upper atmosphere and therefore would be a factor in climate change even if there was no solar variation or cosmic ray variation.
The current situation is somewhat ambiguous in this regard. The north to northwest drift of the NMP from 1840 to 1960 was well correlated with gradual warming and the reason for that may have been the north to northwest drift of the mean position of the arctic vortex.
Since about 1970 the drift has been more westward than northward and also there has been a weakening. The net effect may be more chaotic on atmospheric flow patterns. Perhaps the much-discussed theory that polar vortex location in recent winters has been displaced south because of warming in the arctic is actually a result of this chaotic new state.
If the NMP continues to glide west at its current rate, and if it eventually acquires a southward component too, it may end up somewhere like north-central Russia or even Scandinavia, and that could produce a much different looking hemispheric mean circulation. Climate evidence is spotty on this subject (aside from glacial episodes) but there is some indication that around the tenth century, far eastern Canada had much milder winters and a mean southerly flow. The position of the NMP before 1600 is a matter of some debate, but best guess is that it used to be in the far northern Atlantic basin before heading quickly east towards Canada’s western arctic. It is thought to have arrived in Victoria Island around the 17th century and was reliably located by Ross near the Boothia peninsula in 1839.
This is all a background part of research I have been doing on climate and I think the role of the magnetic field could be fairly significant although not a make or break driver like solar heat output would be. As to the cosmic ray connection, I find this very nebulous, if it is just negatively correlated with solar activity then how do we separate cause and effect impacts of each on climate? Hard to say.
i am always fascinated by the immaterial value of anything related to the climate. anything related to the sun can be summed up easily, without it we are all dead.
yes Kenji, I just love watching reports where a bright red hue covers the areas when the temp get to 68 f. they really must think we are all stupid as opposed to just 50% of us.
I’ve found that this link helps me to understand some of the things these articles cover:

I really hate being proven right in this area. Got into looking at basis of presumed CAGW in detail in 2009 and quickly determined it was a statist con job of gargantuan proportions. I grew up in N Alberta and liked the cold until I moved to S central BC. Now I’m hoping for the predicted global warming but Haven’t seen a snow free winter in a decade.
