Very true about the water vapor.
Vapor is in a vicious feedback cycle. As the earth warmed during the Industrial Revolution, more water was released as vapor. This vapor is a greenhouse gas which fed into the earth temperature rise all the more.
Vapor creates more vapor etc...
Fact of the matter is. Our global temperature is rising, a lot. It is changing things before our eyes. Make no mistake, the change will not be beneficial to humans whatsoever. We are adapted to the world as it is.
CO2 is recognized as the keystone of human induced global warming. It is the biggest GH contributor that we actually have control over the emmission of. Look at your own graph. Among the biggest contributors are power plants, automotive, and agricultural.
These can all be fixed with available technology. We have grandfathered power stations that don't have to even attempt to be clean because they were built pre Clean Air Act. Others that find an economical balance between federal fines and better CO2 scrubbers, damn the environmental impact.
Too many people wasting gas on inefficient behemoths.
Farmers who spread too much fertilizer, allowing greenhouse components to release into the atmosphere.
Something is happening. There are things we can do. We aren't doing them.
