It is hard for people to understand core concepts in mathematics.
There are two concepts that are particularly hard and they lead to the current hysteria about armageddon caused by human forced global warming.
The first is volume. The second is order of magnitude.
Let’s start by ignoring that CO2 is what we breathe out 600 times an hour. We breathe it out at 100 times the concentration that we breathe it in. Yet we can barely detect it at that level (4% of the air). In a room with 3% CO2 or a coffin, we will start breathing faster, slight panic.
Most people can’t picture volume. Go into an average size room (16 feet wide 20 feet long 8 foot ceiling). Now form a rough ball with your hands that is 5 inches in diameter. That ball represents the percentage of the air in that room that is pure CO2. Now make the ball with a 1 inch larger 6 inch diameter. That is the amount of CO2 that is projected to cause a dangerous increase in global warming that could end human habitation.
Now take this math lesson and laugh at the next person who believes in human caused global warming hysteria.
Next, let’s take a chart with a zero degree line on it and show what the global temperature change looks like over the past 135 years. Roughly 57F degrees for the whole period. I’m ignoring that the data is very unreliable until 1979, because on this chart it is irrelevant.
The variations of global temperature are several orders of magnitude smaller than is of any consequence.
We are living with an hysteria born of people who can't understand volume and magnitude.
