The Left is in charge of our Dictionary. Sad to say.
And the Left has zero interest in science, particularly when it is in conflict with its Agenda.

But coin flips are coin flips and the Al Gore Coin Flip turned up HOTTER. That’s life. Sorry about that Al.
The attempted to win that argument by changing it to “climate change”. That’s what they do with everything; change the name.
