Human-caused warming is resulting in a broad range of impacts across the globe

Nature has published the first article to "formally link observed global changes in physical and biological systems to human-induced climate change, predominantly from increasing greenhouse gases." See news story here and the article, "Attributing physical and biological impacts to anthropogenic climate change" (subs. req'd, abstract below).

NASA's discussion of the piece here explains, "human-caused climate change has made an impact on a wide range of Earth's natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa." The image at right: "Impacts from warming are evident in satellite images showing that lakes in Siberia disappearing as the permafrost thaws and lake water drains deeper into the ground." The lead author explained:

Grist asks McCain about contradictory messages on nuclear subsidies

John McCain hosted a call-in with bloggers today following his address in Columbus, Ohio, in which he outlined his priorities for a first term in office. Grist got in a couple of questions: You mentioned climate and energy in your speech today, that they would be among your top priorities, and that has also been […]

How three Rust Belt cities are changing

For more on Rust Belt cities, see our full feature on sustainability initiatives underway in Cleveland. It may not be intuitive to link an area historically associated with steel mills, coal mining, and automobile assembly lines to sustainable development. But green growth is catching on in the Rust Belt, long an economically unendowed area of […]

Prius sales top 1 million

Worldwide sales of Toyota’s Prius hybrid have passed the 1 million mark, the auto company announced Thursday. The world’s first mass-produced hybrid was introduced in Japan in 1997 and in other markets in 2000. While it was at the time a risky business venture, it didn’t take long for the word Prius — Latin for […]

One big corpration dominates the soon-to-be-prized potash market

Industrial agriculture currently stands as humanity’s big plan for "feeding the world" as global population moves toward 10 billion and the earth warms. Increasingly, as oil supplies tighten and prices rise, we’re looking to industrial ag to fill our gas tanks, too. Unhappily, this relatively new form of farming relies utterly on three elements — […]

The eternal cycle of liquid coal reincarnation

Ali Velshi on CNN, Wednesday morning: "What if you could take a lump of coal and turn that in to your gasoline?"

What if, indeed? A brief (very brief) stroll through the archives...

The problems and principles of energy descent

"How did you get there, Roo?" asked Piglet.

"On Tigger's back!  And Tiggers can't climb downwards, because their tails get in the way, only upwards, and Tigger forgot about that when we started, and he's only just remembered.  So we've got to stay here for ever and ever -- unless we go higher.  What did you say, Tigger?  Oh, Tigger says if we go higher we shan't be able to see Piglet's house so well, so we're going to stop here."

-- A.A. Milne, "The House At Pooh Corner"

My kids were out climbing trees yesterday, supervised by Eric and our visiting friend and my honorary brother, "Uncle" Jesse.  Isaiah really wanted to climb up to a particular spot, but couldn't get there on little four-year-old legs.  Jesse helped him up part of the way, and then told him he had to do it himself or be content with where he could get to.  Jesse observed, "I wanted to give him a boost, but only up to a place he could get back down from himself."

I was struck by what a useful metaphor and perhaps even principle was embodied in that casual statement.  I was also reminded, perhaps because I've now read Winnie the Pooh to my children approximately 1,000 times, of the classic representation of what happens when you climb up and can't climb down. If you can forgive the cuteness, it does seem apt.

Let us imagine ourselves climbing up a rather steep and precarious tree, boosted up by fossil energies into a place we simply could never get to without them. The problems we are facing right now all originate in our fundamental inability to voluntarily set limits -- that is, at no point did most of us even recognize the basic necessity of stopping at a point at which we could get down on our own, without our petrocarbon helpers. So right now we look like Tiggers high in the trees -- we can climb up, but we can't climb down. Is the problem our fear or that our tails (our structural addictions to energy) get in the way? It can be hard to tell. But what is not terribly hard to tell is that one way or another, we have to come down -- and probably quite rapidly. The goal is to avoid a painful "thud" upon descent.
