The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C. (Google, copy-paste). So we're now talking about superconductors that could exist in certain conditions on the earth without human intervention. That's pretty amazing.

Now we just need to figure out how to make it work somewhere a bit warmer.

As soon as one reads "1.5 million atmospheres" one realizes this is clickbaity science.

Is this cool, in the geekiest way possible? Yeah.

Is it "near room temperature"? Hell, it's not only not even temperate, it's not even arctic.

And only when the pressure is well beyond Venusian.

From the article: "...hydrogen sulfide under a pressure of 1.5 million atmospheres exhibits phonon-mediated superconductivity at 203 K".

So, yes, dry-ice level temperature, but incredibly high pressure.
