The temperature goes up and the temperature goes down. That's the way it is on the Planet Earth.
If there is a permanent "Global Warming" due to greenhouse gasses, just think of it as "Glaciation Insurance".
"It hasn't been this warm in 150 years!" Is the cry.
Well guess what that means? 150 years ago it WAS this warm.
This great reply will be stored in my old remaining gray cells to shoot down the global warming whiners when they make this stupid statement. Often, the time span is even less like 30 to 50 years.
Indeed. And what caused it to be this warm 150 years ago? Wagons with too many horses?
