The sea was wet as wet could be,
The sands were dry as dry.
You could not see a cloud, because
No cloud was in the sky:
No birds were flying overhead
-- There were no birds to fly.

I can recall back when my grand father who used to hunt ducks came back home with none.
He told me there were so damn few of them flying that he could not bring himself to shoot them.
I grew up thinking that is what conservatives were like.

Antarctic CO2 Hit 400 PPM for First Time in 4 Million Years

"Carbon dioxide has been steadily rising since the start of the Industrial Revolution, setting a new high year after year. There’s a notable new entry to the record books. The last station on Earth without a 400 parts per million (ppm) reading has reached it.

A little 400 ppm history. Three years ago, the world’s gold standard carbon dioxide observatory passed the symbolic threshold of 400 ppm. Other observing stations have steadily reached that threshold as carbon dioxide spreads across the planet’s atmosphere at various points since then. Collectively, the world passed the threshold for a month last year.

In the remote reaches of Antarctica, the South Pole Observatory carbon dioxide observing station cleared 400 ppm on May 23, according to an announcement from the National Oceanic and Atmospheric Administration on Wednesday. That’s the first time it’s passed that level in 4 million years (no, that’s not a typo)."
