Rows and floes of angel hair
And ice cream castles in the air
And feather canyons ev’rywhere
I’ve looked at clouds that way
But now they only block the sun
They rain and snow on ev’ryone
So many things I would have done
But clouds got in my way
I’ve looked at clouds from both sides now
From up and down, and still somehow
It’s cloud illusions I recall
I really don’t know clouds at all
From Joni Mitchell's Both Sides, Now. You only need to write one song like that in your life.
But this piece is about changing cloud cover, and how it effects heat balance on the earth. It seems to be a changeable thing. Scientists don't understand clouds very well.
