Earth's Magnetic Field is Weakening
Earth's Magnetic Field is Weakening
At least parts of it are. Some speculation that a pole reversal might be immanent (or indeed eminent)

Re: Earth's Magnetic Field is Weakening
Have we tried turning it off and on again?

I don't remember a year when I haven't heard speculation of an imminent pole reversal.

I assume if it happens we'll have to turn all our maps upside down and all our fridge-magnets will drop off.
Something needs to be done!!!

Re: Earth's Magnetic Field is Weakening
I was under the impression that they take hundreds or thousands of years to happen? Which means the word 'imminent' really needs to be caveatted with 'geologically'
I expect that would be an incredibly difficult time to live through for all sorts of reasons, so judging by how 2020's gone so far I'd be very surprised if we don't have a reversal in the next few weeks, ushering in an age of geomagnetic chaos.
We have the right to a clean, healthy, sustainable environment.

Isogonic lines (lines of equal magnetic deviation) are moving faster than you might imagine.
Currently, in the UK they are moving West at a rate of about 2km per month.

My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!

Re: Earth's Magnetic Field is Weakening
Right, so this is interesting - obviously the magnetic north pole is a reasonable distance from the actual north pole. So how does the process of reversal happen, exactly? Does it slowly move down through lower lines of latitude like a gap yah student? And what would be the impacts if it did reverse?Bird on a Fire wrote: ↑Tue Jun 09, 2020 8:19 pmI was under the impression that they take hundreds or thousands of years to happen?

It's rather like domestic power from nuclear fusion, which, I was informed in 2010, has been 30 years in the future since the 1950s.

It is still decades away.

The IET magazine in about 2008 (It's now removed from their website) had an article about this - interviewing a senior fusion researcher.JQH wrote: ↑Wed Jun 17, 2020 4:07 pmIt was 40 years in the future when I was a student in the late 1970s.darth tater wrote: ↑Wed Jun 17, 2020 3:52 pmIt's rather like domestic power from nuclear fusion, which, I was informed in 2010, has been 30 years in the future since the 1950s.

He stated that getting break-even wasn't the main engineering challenge. But the lifetime of the plant was. With current technologies, the reactor would have a max lifetime of about 18-months.
Have you considered stupidity as an explanation
