In cities like London and Pittsburgh, the impacts of industrialization were immediate and obvious. Was there any talk at the time of this phenomena affecting the world - or regions - on a more general scale? In short, what did the scientists of the day believe would be the consequences of mass industrialization?
This may help as part of the answer:
Svante Arrhenius was a chemist who in 1896 demonstrated the greenhouse effect and that CO2 was a gas that caused it. Later on he stated that industrial activity produces enough CO2 to warm the earth and will guard against any future ice ages.
Prior to that scientists in the mid 1800's realized that earth was warmer than it would be if it was surrounded by a vacuum instead of an atmosphere . This did lead to speculation about about climate change due to gases in the atmosphere but this only gained wide started acceptance with Svante Arrhenius' work.
