Radioactivity in the ocean: Diluted, but far from harmless

With contaminated water from Japan’s crippled Fukushima nuclear complex continuing to pour into the Pacific, scientists are concerned about how that radioactivity might affect marine life. Although the ocean’s capacity to dilute radiation is huge, signs are that nuclear isotopes are already moving up the local food chain.

Breaking the habit

Rob Hopkins describes our fossil-fuelled industrialised lifestyle as an addiction. We’re addicted to oil. And that presents humanity with a major dilemma: we find ourselves stuck inside a destructive self-replicating system with very few ideas of how to get out of it. We can either get together and find ways to liberate ourselves, or face the consequences of a planetary meltdown. Tough call either way.

New report suggests shale natural gas is worse for climate than coal

A new study from Cornell suggests that the production of natural gas from shale using fracking techniques generates more greenhouse gases than burning coal. The report has generated coverage by New York Times, BBC, Wall Street Journal, Houston Chronicle, as well as a response from the NG industry. (Article extracts and links)

An infusion of commons thinking can transform the future of our communities

Public process as it exists today is not a desirable commons-based, inclusive, creative, bottom-up assertion of ideas by the people—although that is what it pretends to be. It’s actually an expert-driven, one-way dissemination of ideas from the top.

The local passivhaus: an interview with Justin Bere

The ‘holy grail’ in terms of the construction of new sustainable buildings is homes that reach the highest level of energy efficiency, whilst also using as high a proportion of locally sourced materials as possible, what we might call ‘The Local Passivhaus’. Two buildings, recently completed in Ebbw Vale, known as ‘The Lime House’ and ‘The Larch House’ have moved this concept forward significantly.

“But you’ve offered no solutions”: an illustration of Kuhn’s incommensurability thesis

“You’re so pessimistic,” one student said. Another added, “There are alternative energy sources and electric cars that are coming along.” Yet another said, “Look, oil prices are high because of speculation –there’s really lots of oil left.” … Another, who had not spoken during the discussion, said, “I get what you’re saying; it’s pretty damned late to be thinking about this stuff if you’re right, isn’t it?”

Your bike – the coolest part of your disaster kit

When hell breaks loose, a car is a very limited beast. It can carry a lot of stuff or multiple people, but your car is easy to put out of commission. Cars run out of gas; they break down. And cars can be blocked by debris, leaving you a long way to go on foot.

But what about bikes? You can get just about anywhere on a bike if you don’t mind lifting it over obstacles and weaving your way around the stalled traffic. Fast as a car on anything other than a clear highway, nimble as a pedestrian, a bicycle also gives you a long range.
