I just wanted to say my piece about the global warming issue.
I have always been aware of the fragility and finiteness of our world, and the constant need to have MORE every year, including the need for economic growth every year, has always seemed insane to me. That is to state my political world view. Being worried about our world has seemed a game for the far future, not the near term. That is now changing.
The most recent IPCC panel came under fire from the right for being too alarmist(big surprise), and the left for not being accurate. More specifically, the people who seem to know what they are talking about, and are not part of the conversation at the national level, are either scared, or past being scared and are preparing for the worst.
They all seem to have one thing in common. They believe we are PAST fixing this problem, except for James Hansen, who has had some level of optimism, although, he has been quiet lately. They say we are blowing past all climate model predictions.
Energy limitations are pushing us into new fracking techniques which release vast amounts of methane, and the Conservative governments are NOT open to stopping this, or even listening to objections.
If we are PAST the major tipping points, and are opening up the throttle on Arctic exploration, and all energy production, including fracking, how can we hope to survive the coming warming events, coupled with the real game changer of ocean acidification</a>?
It seems no politician is taking this very seriously, or even seems to understand what this could lead to. Ocean level rise is of course, scary, but the acidification and chemical change of the Oceans could lead to a planet with no AIR! Or at least a human compatible air.
To finish, I must say, at this point, no "invisible hand" of the "free market" is going to fix this. It is what created the problem. We need wisdom, and knowledge. And the courage to speak up, and take extraordinary steps. This might mean actually finding a way to scrub Co2 from the air, actively, instead of just slowing down our destructive economy. Of course this also means altering our political/business arrangement. Not an easy task, to say the least. This is one of the main obstacles to our salvation. I know, that sounds rather melodramatic. But, if you take the evidence as I have seen it, and I don't know if you have seen most of it, it is a melodramatic moment for our species, and perhaps all animal species.
For one concise article on our predicament, I would suggest this guymcpherson.com/2013/01/clima…, by Guy McPherson.
