In the 1960s it was “THE GREENHOUSE EFFECT!” that was going to destroy us.
When that did not happen it was “THE COMING ICE AGE”going to freeze us.
When that didn’t happen it was “GLOBAL WARMING!”
Then “CLIMATE CHANGE!”
Now we are returning to “THE COMING ICE AGE” threat again.
Engines stop runnin’, the wheat is growin’ thin.
