It's just that the activists have certain arguments which are scientifically nonsensical, which then can be pointed to, to discredit the entire enterprise. 

Like the rate of change is the big one for me. Predicting the outcome of a system for which we do not understand all the parts is one of the most difficult things to do in science, yet you have morons saying constantly things like 'In 10 years it will be too late!'

For anyone who knows better it again makes the whole thing look suspect even if much of the evidence bears out.

So when should we start acting? As you said, we can't really predict when it's going to be "too late" to act. Shouldn't we like, try to not throw so much trash into nature? Maybe cut down on the use of bad chemicals?
