Climate Change

[SYZ]

The more the air warms, the more water vapor it can carry as humidity. For every 1ºC that the temperature rises on average, the humidity rises by 7%. And that water vapor is a greenhouse gas too, trapping yet more heat. While clouds can not only trap more heat but block sunlight, the net effect is still in favor of warming.

I'd have to disagree with this (bolded) claim.  The 7% increase figure doesn't correlate solely with temperature.  It
ignores the amount of water vapour in the air.  If the water vapour content remains the same and the temperature
drops, the relative humidity increases. If the water vapour content remains the same and the temperature rises,
the relative humidity decreases. This is because colder air doesn't require as much moisture to become saturated
as does warmer air.
