The numbers are in for this year’s summer sea ice extent in the Arctic Ocean. By most measures the ice loss in 2011 came in a close second to the current and still record holder, 2007.

But the failure to set a new record for the least amount of summer Arctic sea ice observed during the satellite era (which begins in 1979) has done little to alter the overall picture of what is going on there. Summer sea ice has been in decline in the Arctic Ocean since, conservatively, the mid-20th century, and it has been picking up steam. And sea ice declines in the Arctic are now pretty clearly discernible in the other seasons as well. (What has been going on around Antarctica is a different story).

But for those who lose sleep at night over the implications of the Arctic sea ice loss to both the local, regional, and global environments, there is a silver lining.…

Ten years ago this month, a landmark book was published that put neo-Malthusianism on the defensive. The unvarnished facts were there to weaken doom-and-gloom prognostications, but it took a rare individual named Julian Simon (1932–1998)  ) to uncover the anomalies and present them in integrated and compelling form–and to win the most famous wager in the history of economics!

Then came a young Dane named Bjørn Lomborg set out to refute Simon but instead rediscovered the bogey of fixed-pie, depletionist thinking. This audacious 36-year-old also found that whether the result was of market progress or regulation, virtually all environmental indicators were trending positively, not negatively. Lomborg could agree with the title of Simon’s last major public address, “More People, Greater Wealth, Expanded Resources, Cleaner Environment.”

A Heated Debate

And then, with the debate joined, came a slew of establishment neo-Malthusians, led by John Holdren, now Obama’s science advisor, who got emotional and nit-picked.…

[Editor note: Austrian-School economics is at the forefront of today’s pivotal debate over the limits of government, a debate that certainly includes public policy toward the master resource of energy.

Yesterday’s introduction of Rothbard is joined today by a tribute to “Mr. Libertarian” by  Roger Garrison, currently professor of economics at Auburn University, upon Rothbard’s death. Subtitles have been added to Roger’s tribute of 16 years ago, and he has graciously added a postscript for this republication. Enjoy on a hammock this hot summer with a glass of lemonade if you can!]

                        Murray Rothbard (1926-1995)

In the late 1960s, my interests were far removed from Austrian economics—and from any other brand of economics, for that matter. I hadn’t yet heard of Murray Rothbard and thus couldn’t even have imagined that I would be catapulted by him into the midst of what would later be termed the “Austrian Revival.”…

“The economy is not recovering…. It’s now impossible to deny the obvious, which is that we are not now and have never been on the road to recovery.”

– Paul Krugman, “The Wrong Worries,” New York Times, August 5, 2011, p. A21.

Federal energy policy is being driven by the failure of neo-Keynesian economic policy.

Stimulus spending was supposed to end the Great Recession and transform tax expenditure into additional tax revenues. Instead, we are left with both recession and broke government. Obama borrowed from the future and made the present worse. George W. did his share too.

Three Strikes: Is Keynesianism Finally Out?

Keynesian economics failed during the Great Depression (will more textbooks now admit it?). The activist approach of Herbert Hoover (the first New Dealer, according to Murray Rothbard) used the powers of government to slow the liquidation of unsound investments, narrow profit opportunities, injure international trade, and block employment.…
