Jesus Christ, whoever wrote this “article” has no idea what they’re talking about. The researchers achieved sub-zero temperatures with a solid refrigerant, which is impressive. It has however absolutely nothing to do with climate change, because the heat still has to go somewhere. And the point that gas refrigerants are horrible greenhouse gases is not generally true anymore. Most new systems use gases as refrigerants that have equal or less impact on the atmosphere than co2 if they’re released into the atmosphere. And that only happens if the loop is damaged, under normal operation it should stay sealed.

Honestly, I’ve given up on Pop OS and cosmic. System76 clearly overestimated their abilities with the decision to develop their own desktop environment. As a result they have been in development limbo for cosmic for multiple years now and at the same time have abandoned their existing distro and its users. Pop OS is still based on Ubuntu 22.04 with no official upgrade path.

Keep in mind that this post is by a company that offers one of the options they compare. So there is an obvious conflict of interest, and I wouldn’t trust the conclusions that were reached
