Exactly. So then ask her what the correct “global” temperature is.
If it’s -130F at the poles and 270F at the equator distributed in a polar format that made the average per square mile was 70F throughout the planet, would that be just as good as 70F distributed constantly from Antarctica to the Sahara?
Is it a good idea to have seasons? Why? Is change good or bad? Which change? If we stop global warming, how do we know when to start it again?
Let’s also not forget urban heating. Fifty years ago, the NOAA temperature censors were away from population centers, but as we have grown, those centers have surrounded these locations and have effected readings.
