We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.

Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.

Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil.

Climate change is not just about carbon dioxide levels and melting polar ice caps. It is about our public health and protecting our Earth for future generations.

Driving a hybrid car could save about one ton of carbon-dioxide emissions per year but adopting a plant-based diet would save nearly one and a half tons over a comparable period.

It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that but it's got all the sort of terms that religions use... The greens use guilt. That just shows how religious greens are. You can't win people round by saying they are guilty for putting (carbon dioxide) in the air.
