One nitpick: true water vapor is invisible. If you can see it then it is no longer water vapor nor a greenhouse gas. It has condensed into liquid droplet form which has very different properties.
The highly biased NYT article neglects to mention how man can influence how clouds form. By adding a small amount of inert particulates to the air we can increase cloud formation if we want to.
Leftists advocate for most humans to die off. We cause them too much envious grief. So which is it? Do they want to sustain human life so it prospers or do they want most of us to go? They can't have it both ways.
Only if there is water vapor to begin with. And why should we try to change it? It is a function of a self-regulating system and altering it is just asking for problems.
For instance, flooding an engine with gas doesn't make it run better.
