(Whoa, I wrote a bit of a novelette here, sorry about that.)
I don't really disagree with you. When an issue makes it to true hot button status, like this has, then, I too wish people would make the time to educate themselves on the particular issue.
Unfortunately, this eventually creates a trend of just about any issue that someone decides is most important to them, ends up blown way out of proportion, and becomes added to the list of hot-button issues.
The issues that perhaps deserve this extra personal exposure most become difficult to identify, and the the quandary comes back to which issue is the most important to spend your time researching.
I won't speak for anyone else here, but, when I see an issue that the arguments are largely dogmatic, with a sprinkling of science thrown in, I tend think that perhaps my efforts would be better spent worrying about things I am likely to have more ability to help produce a beneficial outcome over.
I believe the pragmatic approach to global warming is to let the scientific branch of society determine the nature of the problem, verify it, and work with engineers to determine a workable set of options as solutions, which they then bring back to the persons responsible for making decisions. (Presidents, Kings, Prime Ministers, Dictators, Congress People, etc.)
Then the responsibility to determine the proper action to take needs to be addressed by the decision makers. To do this responsibly, they need to consult with the economists to determine what the most reasonable solution (as presented by the scientific community) to implement would be (in terms of cost-effectiveness), and set the priority of the problem accordingly to the rest of the issues that would hopefully be handled in the same way.
Once the proper action is determined for each issue, and the relative priority is set, then the decision makers need to determine how many of these issues they can really afford to deal with (in terms of what resources we have available, not how expensive is it, because it has already been prioritized), and then act accordingly.
The issues that are not dealt with get put back into the pool of things to be dealt with when it is possible to do so, and they will be re-prioritized with the next issues that are found.
Where this comes off the wire, is when an issue doesn't get prioritized in the way that some think it should, they become angry about it, and issue becomes political.
At this point, science is thrown out the window, and the proponents use emotional arguments in an attempt to give their issue higher priority, when, in fact, the reason it was put off, was it just didn't make the cut in terms of priority, or possibly that the solutions presented were deemed too costly to implement on the grand scheme of things.
The natural reaction to this for the decision makers is to attempt to put down the emotional arguments, which really doesn't work well in society, so they fight fire with fire, and their argument becomes emotional, too.
We end up with a great big mushroom cloud of emotion, where logic and reason are supposed to prevail, but are, for the most part, conspicuously absent.
Until we can agree to remove the emotion from the arguments, and simply concentrate on the problem, and its viable options, I think we will continue to spin our wheels.
As to the question itself, lets ask Joe Public what he thinks: (my observations)
Is Global Warming happening?
"Maybe so. If for no other reason than the warming trend that has happened since the last Ice Age."
(But, it is not because Joe Public has a tangible way (to him) to know for sure. If he did, there would be no buts about it.)
Do you (or anyone else) know exactly what is causing it?
"No, but, I don't think we are helping matters as much as we could with our environmental practices."
(So, Joe would likely agree that there is something we should do to attempt to mitigate the effects of what we are doing to our environment.)
Do we know what actions we can take to stop Global Warming?
"No. But, that is why we have scientists, and engineers."
(Joe Public doesn't know what the right action(s) to solve Global Warming are and doesn't think it is his job to know.)
Joe, what should be do about Global Warming?
(Joe Public is now paying attention to all of the arm-waving, and both sides of the argument are pretty intimidating to him.)
"On one hand, you have the 'We have to do SOMETHING!' crowd, which makes me think, 'Yep. Gotta do something because it sounds like the right thing to do.'"
"On the other hand you have the 'What if we do the WRONG something, and bites us in unexpected ways?' crowd which makes me think, 'Well, maybe we ought to wait for a better understanding before we act.'"
End of interview.
At this point, Joe Public is effectively paralyzed, and the pressure coming from both sides instills a need to make a decision, which is likely to be dogmatic, and will end up doing nothing other than intensifying the argument.
Joe has an alternative to self-educate himself about Global Warming, but, his time is valuable to him, so it's a task, and a half, in his eyes. And, he figures that scientists, and engineers, should be doing this for him, as that's their vocation.
If this problem is really as big as it is made out to be, he should drop everything he's doing, and begin studying the problem for himself. On the other hand, if it isn't, he will consider it a waste of his time. Either way, he will resent having to do the work because it takes away from his most important resource, which is his time.
Unfortunately, the sheer amount of work required to form a completely well-informed opinion, could take him years to study existing efforts to a point where he is satisfied with the veracity of what he is being told, and only then can make a truly responsible decision.
Any effort to self-educate that is less than that, will be omitting data, and views, that may be pertinent to the discussion, and he may just as well go back to the sound bites he hears on Fox News.
So, here we are.
If I were a decision maker, here's how I would want to handle it:
I think the only realistic solution would be to make some token effort that appeases both sides of the aisle, and hopefully lets the argument die down, and fall under the radar, eventually.
In the meantime, I would ask the scientific community to continue to (quietly) study the problem, find any possible solutions, then bring them to the table (quietly), and we'll work together (quietly) to address them as soon as it is practical to do so.
The key to solving it in my mind is to keep it from getting political as much as possible.
