Climate alarmists are obsessed with taking CO2, now at 418 parts per million (ppm), back to a pre-industrial level—perhaps to 280 ppm, where it was at 200 years ago. But why stop there? If they want to restore the Earth to its pristine condition before man ever walked on it, why not take CO2 back to the level it was at 500 million years ago? You might be surprised to learn that back then CO2 was at 5,000 ppm.
When the air is rich in CO2, plants breathe easy, become drought resistant, and actually start reclaiming deserts. The ideal level of CO2 seems to be about 2,000 ppm—a far cry from the arbitrary level of 280 ppm that climate alarmists yearn for. CO2 emissions from fossil fuels are greening the planet, growing bumper crops, and feeding all life on Earth.
