@tubemonks Carbon dioxide diffuses due to molecular movement so it is fairly evenly spread. If all the carbon dioxide separated out it would form a layer about 3 metres thick at the surface. That said, the whole concept of greenhouse gases is a misnomer. Greenhouses do not affect radiation. Sit in a greenhouse on a cold clear night and you will freeze. You are probably right to say that water vapour is the most important substance which holds in heat. The main instrument of climate change (if it is a genuine phenomenon) is probably deforestation. The severity of the floods is mostly due to fast run off in the Pennines because of EU-subsidised sheep farming, which means that the land cannot act as a sponge.

@nineteenninetyfive How is carbon dioxide a greenhouse gas? Greenhouses work because the glass stops cold air from escaping through convection. Please explain the mechanism.

This flooding is worse than it would otherwise be due to the rapid runoff from uplands (the Pennines, in this case) used for EU-subisidised sheep farming. But that would go against the LibDem narrative. These uplands should be managed so that rain is held back, by planting more trees and constructing holding lakes, which makes the land act like a giant sponge.
