Is carbon dioxide a dangerous pollutant? Well not according to Princeton University physicist William Happer and Apollo 17 astronaut Harrison Schmitt who recently co-authored a powerful article in the Wall Street Journal. They say that contrary to popular global warming myth, current levels of CO2 in the atmosphere are actually low, and that levels of 3,000 parts per million or more in the distant past were actually a great benefit to plant and animal life. They note that with additional CO2, plants produce fewer stomata openings in their leaves and are able to use water much more efficiently. With little correlation shown between CO2 and global temperature, it sounds like carbon dioxide is nothing but a boon for the Earth and all of its inhabitants.
