They need a 1:1000 to have a valid argument.
Well, the IPCC report into climate change only reported a 9:1 chance of global warming being due to humans. I think most people would agree that climate change being anthropogenic is a valid arguement, even those who sceptical of the science.

Even deferring the decision is, itself, a decision that we're making all the time. So really, all we can do is go with the best data available and do what we can.
