I was arguing the point of ozone caused global warming. Water vapor is much more common than carbon emissions on Earth, and it too is considered to be a greenhouse gas, but really, water has been evaporating on Earth for millions of years. So how could we have be making the Earth any warmer since the 1970s just by releasing CO2 into the atmosphere? Besides, there have been time periods where the Earth has been much warmer, and we are only just coming out of an ice age, so yes, the Earth is getting a little, I think that it is wrong to assume that we are doing the planet any harm, and that is if we are contributing to it at all.
