Isn't rare earth metals mining insanely pollutive? I've heard they can be found all over the world but only China mines them massively because nobody else is willing to destroy their ecology.

It often is as I understand it. But it's also helping reduce pollution through electrification so it's a balance. I (being not far from there) feel it's better to have polluting operations like this in heavily regulated and modern economies where there is a good chance the damage can be minimized at least.

It's important to understand that electrification does not reduce pollution.

But he was Finnish

But a Swedish speaking Finn and it seems he made his discoveries while living in Sweden. From wikipedia: "Johan Gadolin was born in Åbo (Finnish name Turku), Finland (then a part of Sweden)." [0] "In 1779 Gadolin moved to Uppsala University." Uppsala is in Sweden. [0] https://en.wikipedia.org/wiki/Johan_Gadolin

> But a Swedish speaking Finn

this is the argument Russia has used to invade Ukraine...

The value of many "rare earths" suddenly plummeted recently when an iron+nitrogen [edit: not "nickel"] alloy/crystallization ("allotrope") was discovered that approximates the properties of the best lanthanide magnets. ("Rare-earths" are not, incidentally, needed for [edit:batteries], wind turbines, or solar panels, however much certain people wish they were, or confidently claim.)

Do you have a link, keywords, so I can read further on this topic? Thanks beforehand.

You may ignore claims there that they are essential for batteries and wind turbines. But they are important in electric drones and robots.

> No rare earth elements are currently mined in Europe This is a little crazy fact I learnt today. Given how much we use, this news hits harder.

It is going to be an agonizing compromise for Sweden - destroy the Kiruna area with extraction (a million tons is a lot) or be environmentally friendly. Currently the Congo and Chile are being torn apart with toxic dollar a day child labor extraction. The Swedes will do a good job of mechanizing/sanitizing the process though. I went to Kiruna once to see the northern lights but they didn't show up.

The find is 700 meters deep and in an already established mine more than 100 years old.

Also most of todays Finland was under Swedish rule until 1809.

Was any part of todays Finland not under Swedish rule 1809?

That's from 2012, are there any further developments?

>"I've wondered how that works" Nice country you've got here. Will be a real shame if anything happens to it.

But the problem with this approach is that NATO actually needs Turkey, it's in a vital position and is locally a major player. Ideally, NATO members need Turkey to be truly cooperative. (You know, discuss, compromise, that old thing.) What NATO really needs is for Turkey to be not directly hostile. That would be incredibly costly. We already got a tiny tiny preview of that by Turkey turning a blind eye to ISIS.

Correct. Turkey has one of the best - maybe the best? Singapore could be better - positions on the planet. The straits alone are a remarkable advantage, much less the direct path along the new Silk Road, the warm water ports, the vast Anatolian plain, etc.

Turkey is one of the most important NATO members, and they know it.

What exactly does this mean? EVs use a ton more rare earth minerals than conventional cars

https://www.iea.org/data-and-statistics/charts/minerals-used...

Solar panels use silicon, indium, gallium, selenium, cadmium, and tellurium. Neodymium and dysprosium are mainly used in the permanent magnets of offshore wind turbines
