Is planet Earth warming, cooling, or staying the same? I often challenge advocates for climate alarmism: what is the temperature of the planet today?
Or we can use any specific day in recent years for which data are available. We cannot know the temperature of the planet thousands or millions of years ago if we cannot even measure it today.
Yes, the question is one single temperature of the entire planet. Not the temperature in Nome, Alaska, or Dallas, Texas, or Sydney, Australia, or in your hometown.
One single temperature reading for the entire globe. To put it that way immediately sounds strange.
But if we don’t have a single temperature reading for the entire planet for today, how can we say if the planet is getting warmer or cooler or not changing at all?
We cannot talk about the temperature in, say, Geneva or London or New York City only. The question is whether the entire planet is getting warmer, not isolated cities.
Some of us have forgotten basic statistics. Some avoided it in school. But most of us are vaguely familiar with the random sampling process used in public opinion surveys.
