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.

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’.

Joining 350.org: the next phase

Today I joined the newly formed Board of Directors of 350.org. I have been a supporter of 350.org since I first heard about the wacky plan to turn a wonky scientific target into a global people’s movement. In the past three years, we have all watched the number “350” morph into a beautiful and urgent S.O.S., rising up from every corner of the globe, from Iceland to the Maldives, Ethiopia to Alaska.
