Time to face the warm, hard facts
TWO facts: Earth's climate is changing; there are things we can do to reduce the damage. Why are we standing around arguing about the causes?
If I see a truck rushing towards me I take evasive action. I don't stop to argue about whether the driver is mad, the brakes have failed, or it is an uncontrollable skid. I get out of the way – as quick as I can.
Let flat earthers believe what they like. Let climate-change deniers pretend they are shivering. If they obstruct, they will have to be pushed aside.
But for heaven's sake, stop wasting time arguing with them.
