Global warming
From Memory Alpha, the free Star Trek reference.
Global warming was environmental damage suffered by some planetary bodies that held, according to Beverly Crusher, "profound medical repercussions" for their inhabitants.
In 2367, Data believed that the Beta Moon of Peliar Zel II would enter the initial stages of global warming when his predictive model suggested an oncoming rise of temperatures and erratic tide surges. It was caused, in this case, by the Alpha Moon using Beta's magnetic field as their exclusive energy source. (TNG: "The Host")
- The events that occurred to Qo'noS after the destruction of Praxis may have involved global warming.
