Water
This is what I KNOW. A cloudy night is warmer than a clear night. Hence water in the form of clouds must be a greenhouse gas. The result of burning fossil fuels is mainly CO2 and Water. There are many more water molecules produced than carbon molecules when it is burnt. Is water a greenhouse gas? Is there more of it in our atmosphere?
We should not be burning fossil fuels, my point has nothing to do with the weather. They are a finite resource and are used to manufacture everything from clothing, high tech equipment, furniture, motor vehicles, building materials and so on. Sending coal and oil up in smoke is short sighted and a waste that future generations will rue.
The human race will find a way of living with climate change, it will never be able to prevent it.
