I didn’t read the whole article- but usually these folks believe man is responsible- they just differ on how much- the excerpt sounded like he still believes man is responsible, but questions how much- The facts show that CO2 isn’t a control knob at all- there isn’t nearly enough for starts, and the facts show CO2 follows heat temp rises, not preceding it-
If you really want to drive those types crazy, ask them 2 questions:
- Is mankind special, or are we just advanced monkeys?
- If we’re just advanced monkeys, then our existence is just another part of the natural world, so why are you trying to curb our natural behavior?
