Will satellite megaconstellations weaken earth's magnetic field?

I for one would like to see the satellites modified with a heat shield so they could punch through and hit a designated deorbit zone. I would even offer my backyard, but I fear it's too small.

Wouldn't that be the ultimate tourist attraction? "Witness the next deorbit round tomorrow at Crater Park Observatory!"

I do not agree that this study can be dismissed so easily.

The arguments about the possible influence of the satellite remains are plausible.

This is something that nobody has thought about before, so it is normal that it cannot be known yet whether this will ever be a serious problem or not.

Nonetheless, like for any other potential source of pollution, future studies are needed to monitor the effects of end-of-life satellites and determine whether they are important enough to warrant some regulatory action, or not.

Sarcasm is never a good look.

The article presents a serious argument as to why this is a possible danger. You don't try to engage with the article, or present a counter-argument.

Given the terrible consequences of weakening the Earth's magnetic field, "We don't know for sure it will happen so we simply shouldn't worry about it," seems unwise.

Sometimes it seems like some people have a pathological need to be a doomer about any human activity.
