Atmospheric humidity is very complex and one of the least understood aspects - like many things involved with climate change, it is not a simple linear relationship. This article summarises some of the points very nicely:Quite worrying isn’t it.
For every 1C increase in global temperature atmospheric moisture levels increase 7 fold and this additional moisture amplifies the warming effect as well as resulting in more extreme weather events eg a third of the entire country of Pakistan currently under floodwater from last week’s storms which were seven times more severe than their normal monsoons.
Correct me if I’m wrong but this seems a frightening (exponential?) growth (+1C = x7 increase in moisture, +2C = x49 moisture increase) which will have devasting consequences in our lifetimes. Maybe we shouldn’t be just thinking of our children but of the horrors we’re likely to face in the very near future.
We reached +1C above pre industrial levels in 2017 and the current rate of increase is now as high as 0.2C per decade.
But we have a hard right UK Govt transferring billions £ of public money subsidising gas and oil exploration and supply and a policy to promote fracking across the country elected by the public.
The key reasons for the humidity paradox are two-fold: the Earth is warming and warmer air can hold more water vapour.
