if these people are right, there is no other topic of import to discuss other than global warming. maybe dr. james hansen is a crank. or maybe he's just so smart we can't keep up. i suspect the latter. his suppositions and theories about where we stand re the earth's temperature and how much carbon we can continue to put out are frightening. and how we respond, or rather what paradigm of human social interaction we use in order to literally save our skins--all of them--that becomes the key question. probably the key question in all of modern human history.
it's...food for thought, though maybe not my cup of tea.
