This they realised was why the Earth was warmer than it should be considering its distance from the sun. So the inevitable question arose: what would happen if those gases changed in concentration? It was known that carbon dioxide was one of these warming gases and it was known that burning coal gave off the same gas. But the conventional view was that the Earth system was so big and complex that nothing we humans could do could have much effect. We surely couldn’t change the climate.
