Then let them sow doubt. If the case is "we're not sure but it's very possible that continued CO2 emissions will cook the Earth", what should we do? Continue emitting CO2, or stop until we're sure that it won't cook the Earth?

It's the precautionary principle - if the science isn't settled, given the catastrophic risks, we should limit CO2 as much as possible until it is settled that emitting it is safe.
