Just wondering. I'm not doing much about it, so my criticism, what there is of it, is directed at me, too. It just seems strange that we're going to sit around, go to work or school, hang out at the mall, buy whatever it is that we don't really need but kind of want, at least until we have it, while at the same time the world heads at a fairly fast clip towards a future that's not going to be very happy for life as we know it. Seems like we should at least be able to muster up the gumption to shut down the country for a day or two and demand the insanity stop while there's still a chance (albeit, a thin one) to salvage the situation. Maybe we're conditioned to believe technology or g(G)od(s) or Democrats will save us, but it's hard to believe we're really that stupid.
Anyway, here's a link to a particularly despressing article by Mike Davis. He ends the essay wondering whether our children's children will have children of their own. Reminds me of the song where Sting sings, "I hope the Russians love their children, too." Maybe the problem is we don't really love our children, at least not enough to save them.

Has the Age of Chaos Begun?
<edit>
But all the major components of global climate -- air, water, ice, and vegetation -- are actually nonlinear: At certain thresholds they can switch from one state of organization to another, with catastrophic consequences for species too finely-tuned to the old norms. Until the early 1990s, however, it was generally believed that these major climate transitions took centuries, if not millennia, to accomplish. Now, thanks to the decoding of subtle signatures in ice cores and sea-bottom sediments, we know that global temperatures and ocean circulation can, under the right circumstances, change abruptly -- in a decade or even less.
The paradigmatic example is the so-called "Younger Dryas" event, 12,800 years ago, when an ice dam collapsed, releasing an immense volume of meltwater from the shrinking Laurentian ice-sheet into the Atlantic Ocean via the instantly-created St. Lawrence River. This "freshening" of the North Atlantic suppressed the northward conveyance of warm water by the Gulf Stream and plunged Europe back into a thousand-year ice age.
Abrupt switching mechanisms in the climate system -- such as relatively small changes in ocean salinity -- are augmented by causal loops that act as amplifiers. Perhaps the most famous example is sea-ice albedo: The vast expanses of white, frozen Arctic Ocean ice reflect heat back into space, thus providing positive feedback for cooling trends; alternatively, shrinking sea-ice increases heat absorption, accelerating both its own further melting and planetary warming.
Thresholds, switches, amplifiers, chaos -- contemporary geophysics assumes that earth history is inherently revolutionary. This is why many prominent researchers -- especially those who study topics like ice-sheet stability and North Atlantic circulation -- have always had qualms about the consensus projections of the Intergovernmental Panel on Climate Change (IPCC), the world authority on global warming.
In contrast to Bushite flat-Earthers and shills for the oil industry, their skepticism has been founded on fears that the IPCC models fail to adequately allow for catastrophic nonlinearities like the Younger Dryas. Where other researchers model the late 21st-century climate that our children will live with upon the precedents of the Altithermal (the hottest phase of the current Holocene period, 8,000 years ago) or the Eemian (the previous, even warmer interglacial episode, 120,000 years ago), growing numbers of geophysicists toy with the possibilities of runaway warming returning the earth to the torrid chaos of the Paleocene-Eocene Thermal Maximum (PETM: 55 million years ago) when the extreme and rapid heating of the oceans led to massive extinctions.
