From greenhouse to hothouse: the language of climate change

, , , , ,

Feedback effects could spark irreversible global warming, says scientists. But what does the word ‘hothouse’ imply? — Scientists warned this week that feedback effects in global warming might tip the Earth into a “hothouse state”, recovery from which could be impossible, even by reductions in CO2 emissions. How frightened should we be about moving from …
