... and couldn't the increase in fine dust particles from ploughing /
exposing dry soil and harvesting of crops, lofted by thermals, help
rainfall by "seeding" the clouds, giving the water vapour something to
nucleate around?


I thought that was the way the article would go when I first started
reading....


My thoughts went something like:

This sound like the hydrology cycle of the Amazon. So where is the
problem in the forest's rape and destruction?

Deserts? With all those bison. (OK I was thinking buffalo) Then:

Isn't Oklahoma in the Midwest somewhere? Or:

Concrete gives a lower dew point reading than farmland? Wow! I wonder
why all the important readings are from airports? And:

What about all the aquifers they drained and are still draining in the
US and A?

But not necessarily in that order.
