Besides, scientists who have studied the temperature of the atmospheres of Mars and Venus and the upper atmospheres of our gas giant planets note a warming over the last 100 years. That either tells us the Sun's radiation output is changing or cosmic rays from outside the Solar System are causing the warming, too.
Roger that. The thousands of sensors in cities with all that concrete are going to read higher, but it’s an artificial increase that bears no relation to overall global heating. AGW is just a ploy for pretty much total control of our lives.
“Everybody talks about the weather but nobody does anything about it.”
Old quote but today the socialist gods try to dupe us into thinking we can do something about it.
