> Take two glass boxes. Fill one with air. Fill the next with air and add carbon dioxide in any amount. Put them outside next to each other in the sun. The one with additional carbon dioxide will get hotter in proportion to the amount of carbon dioxide added.

Any amount? How does this play out with a CO2 concentration of 0.04%?

Yes any amount. It is a simple chemical property of carbon dioxide that it absorbs more sunlight than air does on average. That heat becomes a part of our climate.

It spreads out, like colorants in water.

Think about mercury:

> For example, if Isabella weighs 132 pounds (60 kg), she should consume a maximum of 95.8 µg of mercury per week.

95.8ug is just .0000001596..% of Isabella and yet it's deadly.
