laze noun [C]
/leɪz/
a lava haze: a toxic cloud formed when hot lava flows into cold seawater

Laze plumes can travel with the wind and can change direction quickly, which has prompted authorities to urge the public to avoid the area completely … Even being downwind of the entry point is not advised because the wispy edges of the laze can cause skin and eye irritation and difficulty breathing.

Hothouse Earth noun [C, U]
UK /ˌhɒt.haʊs.ˈɜːθ/ US /ˌhɑːt.haʊs.ˈɝːθ/
a situation where it will no longer be possible to control climate change, leading to large areas of Earth becoming uninhabitable

In a Hothouse Earth, global average temperatures would rise 4–5° C (7–9° F) and sea levels will rise 10–60 meters (33–200 feet) above today’s levels. This would be catastrophic for many aspects of modern civilization. Many agricultural regions would become too hot and arid to sustain crops, making it impossible to feed large swaths of humanity.
