Yea there's just no way. Any response at a global (and, in the US, national and state) level will be 100% reactive, and 0% proactive. Since there are still people arguing over the cause, I'm starting to think it might be more productive to move the conversation from trying to be proactive (which requires everyone to agree on the cause) to reactive (which does not).
In other words, start preparing for the outcome of this. We, as a species, cannot seem to be able to stop what we are doing.
