The global warming box is very simple. You are locked in a glass box. It is see-through, air-tight, and about the size of a telephone booth. An air quality monitor is displaying the CO2 concentration in the box.
When do you push the button to get out of the box? 400ppm? 500ppm? A thousand? Five thousand? A hundred thousand? Do you wait for a baptism of asphyxiation?
We recommend an immediate increase in the federal gas tax of $1/gallon to address this issue.
