Did you read that article ??? Cosmic rays ???? who influence weather pattern in the tropic ????


How??? do cosmic ray influence the weather???????? magical fairy maybe smurf ?? who knows!


Why not this instead

Might be a language barrier thing again, but Elvis, the sun's rays are what they are referring too in the article, and it is the sun's rays that directly contribute to weather patterns on this planet.

Negative. Article is BS and doesn't belong in the Science section.

Article is sensationalized, but it is still correct. The poles flip with reasonable regularity in the geologic record. And it has real world consequences.

Elvis Elvis:

I read the article and this is how it fail!


Premise : Variation , and change in the magnetic sphere of the earth affect the weather. therefore since the earth magnetic pole will switch ( because they are moving more and more each year ,fact!) We are all screw.


Problem there there is no link between change in the magnetic sphere and the weather that we know of ?!?!?!

It's a bit like astrology there is no cause and effect.

People really aught to read up on things before they go wagging their fingers.

There is also evidence that there is a correlation between cosmic ray flux and low-altitude cloud formation. Now, correlation does not always imply causation, and it is also known that the sun is slightly brighter if it is more active, which may also affect cloud formation on earth. But it is at least possible that cosmic rays could have something to do with it. There is a possible mechanism for this: elevated levels of ionization seem to facilitate the coagulation of such molecules as sulfuric acid (H2SO4) in the atmosphere into tiny droplets, which then form condensation nuclei for water vapor. The condensed droplets of water then form clouds.

Clouds have been observed from space since the beginning of the 1980's. By the mid 1990's, enough cloud data accumulated to provide empirical evidence for a solar/cloud-cover link. Without the satellite data, it hard or probably impossible to get statistically meaningful results because of the large systematic errors plaguing ground based observations. Using the satellite data, Henrik Svensmark of the Danish National Space Center in Copenhagen has shown that cloud cover varies in sync with the variable cosmic ray flux reaching the Earth. Over the relevant time scale, the largest variations arise from the 11-yr solar cycle, and indeed, this cloud cover seemed to follow the cycle and a half of cosmic ray flux modulation. Later, Henrik Svensmark and his colleague Nigel Marsh, have shown that the correlation is primarily with low altitude cloud cover.

I've said it before and I'll say it again, we don't know whats causing climate change, or how bad it will be. But in no scenario, whatever it is caused by or whatever the outcome, it isn't pretty. So the best idea is probably to prepare for the worst, whatever it may be.

Amen, brother.

Well, save for my grammatical error. No one is perfect I suppose.

The question is more, does it belong into the "Current events" category !

Last time I checked, my GPS was still pointing to the north.

ooohhh....

Unfortunately, your GPS uses true north, not magnetic north

What GPS do you use that only uses true north? I've never had a GPS that didn't have the options of switching between true north, grid north, and magnetic north.

Forget about global warming—man-made or natural—what drives planetary weather patterns is the climate and what drives the climate is the sun's magnetosphere and its electromagnetic interaction with a planet's own magnetic field.

So it's not our fault afterall?

Negative. Article is BS and doesn't belong in the Science section.

It doesn't belong in the Science section? But some idiot with a hockey stick model does? Really?
So if this doesn't belong in the science section, where does it belong? Canadian Politics?

Sorry, I stand corrected, I'm not all that familiar with GPS. I use these old fashioned things called ..maps

Even maps vary. But the good ones will orientate with their relative grid-north, then show you the difference you'd have to make to adjust a compass for both true north and magnetic north based on the orientation of the map.

[Proculation]

if you remember your Pythagoras well, the tangent of an angle in a circle (or sphere) is almost the same when that angle is tiny.

That means, sinus of 3 degrees is almost the same than the tangent of 3 degrees outside the circle (or sphere).

So, a certain change of the magnetic north pole, even if it's 1000km, the change is calculate via the difference of the angle which is very small.

That means your compass is still ok if the magnetic pole north just wanders around.

[andyt]

The magnetic north pole is heading for Siberia - guess it's had enough of Canada for a while.

Last time I was working with maps, the declinantion between true and magnetic in Vancouver was 23 degrees - not insignificant. But the location seems to moving about by about 15km a year, and accelerating.
