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.

Just curious, as I'm not a physicist, what's the definition of "near room temperature"? Because 203 k = -97F/-70C.

Superconductors exhibit superconductivity in temperature of 30K and less.

High-temperature superconductors exhibit that effect in temperature 90-130K.

Having all that, 200K is really close to room temperature.
