Former senior NASA climate scientist Jim Hansen -- who is either the canary in the coal mine or beezlebub, depending on your point of view on whether scientists ought be activists -- has released an important new summary paper written with a large number of seriously scientific co-authors. The paper was intended for submission in court in Oregon, where a group of young people are suing the federal government for inaction on climate change.
These are big events in the world of climate change. My opinion is that Hansen is neither canary nor demon. He's more like the goldfinch in the coalmine. Not quite as effective as a canary, and certainly not a common metaphor, but you'll know just fine when becomes anoxic.
We will talk about this paper in both EcoEco and EII.
