Tonight is Earth Hour.
You might reasonably ask what that is. It is an environmentalist declaration of a one hour period in which they ask all of us to voluntarily renounce human progress and plunge ourselves back into darkness. That's it. Tonight between 8:30 and 9:30 in your time zone, turn off all of your lights to show your concern and abject ignorance.
Or, maybe not.
All you sinners put your lights on. Let them shine. Turn them all on. See if it is warmer or colder tomorrow. And feel good as you laugh at the idiots that surround us.
