Tracking U.S. farmers’ supply of nitrogen fertilizer

We burn through more of it per capita than any other country; and our appetite for it can only be sated with massive imports. No, not oil–I’m talking about nitrogen fertilizer. With only 5 percent of the world population, the U.S. consumes nearly 12 percent of the globe’s annual synthetic nitrogen fertilizer production. And we’re producing less and less of it at home–meaning that, as with petroleum, we’re increasingly dependent on other nations for this key crop nutrient.

Prof Al Bartlett’s exposition of exponential growth

Prof. Al Bartlett offers useful approximations for understanding exponential growth and its alarming consequences. He gives two rules of thumb for quick calculations about exponential growth but it’s worth noting that these are approximations, quite accurate for small percentage growth values, but not correct for large rates of growth.

Beyond Copenhagen – Now what?

Are current corporate-dominated international institutions inadequate to the task of meeting the multiple planetary survival challenges they themselves have helped create?…Richard Heinberg of the Post Carbon Institute (postcarbon.org), talks about the factors contributing to the stalemate in the Copenhagen climate summit, the other ‘game ending’ challenges confronting the current economic system, and the bottom-up steps necessary to move to a post-carbon economy.

Entropy revisited

One way of looking at our current set of predicaments is that we’ve been on a binge, consuming energy considerably faster than it can be captured and stored by Earth’s ecosystems. While fossil fuels once appeared limitless (and still do to deniers of peak oil), and though we’re literally bathed in energy (in the form of sunlight), the disappearance of the fossil-fuel storehouse accumulated over millions of years isn’t something that can be replaced with anything nearly as convenient as fossil fuels.

Review: Why Your World Is About to Get a Whole Lot Smaller by Jeff Rubin

He gets peak oil…And now, in his bestselling book Why Your World Is About to Get a Whole Lot Smaller, he argues that oil prices, temporarily dampened by the deepest post-war recession on record, will soon be vaulted to new highs as the economy begins to recover, which in turn will thrust the world into yet another recession right on the heels of this one.

India’s decade of wheeled deities (updated)

The veneration of the automobile is a custom that is gradually, steadily becoming more commonplace in urban India. The global auto industry’s major manufacturers are betting on it, India’s central government is betting on it, and tens of thousands of new customers in India are delivering that bet.
