There's not enough of carbon dioxide in the atmosphere.

Ian Plimer: "The other emergency we have is there's not enough of carbon dioxide in the atmosphere. It has been decreasing over geological time from 0.7%...to the current 0.04%. If we halved it all plant life would die...these people are ideologues who don't know history, who are trying to frighten us with so we can open our wallet. This has nothing to do with science, it's nothing to do with environment, it's nothing to do with climate. It's to do with control and power by unelected people over us."
