The Storm Clouds Gather...

A couple of clips from The Oil Drum - a good source of in-depth, reasoned comment, well worth checking out if you don't already know about it:
A new paper by NASA’s James Hansen suggests that immediate and drastic declines (ca. 6% annual) in industrial CO2 emissions are required to avoid catastrophic climatic destabilization. As no realistic political solution exists for such immediate CO2 reduction, prospects for a livable future have now become dependent on a single back-breaking option: rapid global economic collapse. And in ‘Deus ex machina’ style, we may get it just in time.

...and this from Richard Heinberg, also in The Oil Drum:
At the core, though, all of these uprisings are about the simultaneous failure of modern economics and modern politics—even though systems differ somewhat from country to country. People in all of the nations mentioned have one thing in common: crushed expectations. Economists and politicians have promised jobs and growth, but instead citizens are seeing spreading unemployment, rising food and energy prices, and increasing economic inequality. Nowhere are there realistic prospects for a political remedy to worsening economic conditions. Thus, while unrest seems destined to spread and intensify in the months and years ahead, it has no clear long-term strategy or goal.
