Solar wind + Weak magnetic field = No water?

AI Thread Summary
The discussion centers on the potential impact of a weakened Earth’s magnetic field on water retention due to solar wind exposure. There is a consensus that the magnetic field will weaken and eventually flip polarity, though this process is expected to take a long time. Some participants express skepticism about significant water loss during this transition, suggesting that any effects would be temporary and minimal. Historical data indicates that while the magnetic field has shifted, the immediate consequences for water retention are not alarming. Overall, the consensus is that while the magnetic field will weaken, it is unlikely to lead to substantial water loss from Earth.

Is it possible that one day, the Earth magnetic field get so weaken that solar wind could strip off water from earth? I ask this because of this article which leads me to draw the parallel. http://www.geotimes.org/sept04/NN_solarstorms.html

I've read conflicting articles about this -- mostly on if/when the magnetic field will weaken.

However, there is a pretty good consensus that the magnetic field will weaken (and has) sometime soon as it will flip polarity. Measurements of the magnetic field show eventually the north and south poles will flip -- and that they have migrated from their positions already as compared to the past.

You might want to do a search of SciAm and Discovery over the last few years as I think they've covered the subject a few times.
 
I don't think so though that this will happen for a long, long time actually, but I think that the effects will be temporary though. The solar winds probably can't pick a whole lot of water, whenever the top happens.
 
NOVA on WJCTv did a show on this like 8 years ago.

Yes Earth's magnetic field is going to weaken bu thenget strong again. During this time we won't lose pretty much anything because its so short.

Mar without a magnetic field: 2,000,000,000

Earth's max without a field: 3,000
 
Thks to all who replied :)
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
