Worse than Worst Case Climate Change Scenario
A user pointed out this popular media account of a recent Science journal article that finds “the world is now on track to experience more catastrophic damages from climate change than in the worst-case scenario forecast by international experts”. The research found that between 2000 and 2004 global carbon dioxide emissions from fossil fuels increased by three times greater than in the 1990s. The person that forwarded this to me pointed out that “we are beyond A1F1 which with carbon feedbacks [search] means we on track for over +8 degrees C in warming… Over 5.5 degrees C, at this rate of global change, would by best guess be limit of survival for humanity… Coupled with the recent news on the Antarctic Ocean means that IPCC 4 is hopelessly out dated now.” The accumulation of recent science beyond the pondering, politicalized IPCC process would seem to indicate that we have entered a period of abrupt, perhaps run-away climate change that will have severe consequences for the Earth's future habitability. Most scientists are too cautious to make such predictions — indeed the traditional scientific method seems ill-prepared to counter a once off planetary emergency that threatens the survival of existence. It is well past time for drastic measures if we are to have any chance of fighting global heating and winning. I am dismayed by the helter-skelter of schemes and projects that seek to profit from the situation without offering a vision of what must be done to survive. UPDATE: Here is more information [more2] on the finding that CO2 has been found to be rising three times faster than expected — this is an indicator that climate change is on track to be abrupt [search] and perhaps runaway [search].
