What I personally would like to see is clarity. Actual science should be able to provide a clear path forward with measurable results. It is not enough to say that humans are causing this so we should make wild changes. You have to be able to audit the changes and prove that they had the result you expected.
For example, we had cash for clunkers in the US, and have passed numerous laws requiring more and more stringent restrictions on auto emissions, but nowhere do we see the picture of the impact (or lack thereof) of those actions. In fact, from most accounts that had no impact because evidently the problem is still spiraling out of control. If that is the case, we need to re-evaluate our response and try something else.
It is not enough to panic and say there is a problem, you have to be able to see the results of your actions in a measurable way. Until you do that you are just taking knee-jerk reactions, not actually addressing the problem.
"Doing something" is useless if you aren't doing the right thing, and the only way to know if you are doing the right thing is through changes and continual monitoring with updates as we learn what the impact of each change is. This isn't something that can be solved in 5 minutes and forgotten, there are no silver bullets.
