From the perspective of one who has seen this vision for 20 years, it appears now that there is approaching critical mass to consider the unthinkable – taking concerted local, state, then perhaps national action to combat our “contributions” toward climate change. I’ve suggested to skeptics that we take out fire insurance on our houses on smaller odds that a fire might happen than on the odds that our contributions might be changing the climate. Yet until real recently, any substantive action beyond “more study” has been hard to come by.
The political will has been the most difficult nut to crack. Legislatures and Congress are not very progressive when it comes to long term issues. Social Security or national health care are examples of that which we are unable to address, since it requires political sacrifice beyond the next election. And to their defense, it is a rare statesman (as opposed to politician) who has the support of his or her electorate in suggesting we sacrifice in the short term to benefit or reduce risks in the future.
the concern I have is that we are past if not the tipping point, at the least further along in climate change so that stabilization will be near impossible. We can perhaps preclude it getting worse, but the cost from the impacts will make concerted efforts to mitigate our contributions that much more difficult. We are more willing to spend $10 billion to deal with Hurricane Katrina.
So we are down to those skeptics now accepting there are negative impacts to climate change and that humans might be responsible for some of it. Whether we are willing to make any short term sacrifices to mitigate those contributions or just think we can rely on new technology, as Sen. Lisa Murkowski currently believes, remains to be seen. While technology might help long term, we’ve been needing to take short term action for a few decades.
