as a stupid person myself I'd point out that Plimer should check his 'facts'. One is that volcanoes release more CO2 annually than fossil fuel burning. His own peer group the US Geological Survey says nope fuel burning is 135X more. I guess when you've decided in advance who to believe the 'facts' become hard to change.

Ttbn, CO2 stops infrared radiation from bleeding off into space. And instead traps it at low levels. CO2 is a powerful plant fertiliser and promotes plant growth and with that, increased moisture aspiration. Moisture that acts like a thermal blanket, trapping heat. And aptly named, the greenhouse effect.

Plimer is a geologist, not a climate scientist. And relies too heavily on a fossil record, which shows, CO2 from volcanic activity nearly exterminated all life on planet earth around 50 million years ago. It matters not the source of the CO2, it can still lead to an extermination event!

And currently a case of garbage in, garbage out for Geologist, Plimer.

We've never had 8 billion people living on the third rock from the sun and that number is more than we can sustain without quire massive change.

We need to save the forests and our oceans, which are the lungs of the earth. Forests will tolerate selective logging.

And we need to transition to nuclear power ASAP! And recycle all we can. Effective recycling requires very cheap energy! As does desalination!
