Strange bedfellows? Techno-fixes and conservation

I have a new paper out in the peer-reviewed journal Biological Conservation that will be of interest to BNC readers. It is called “Strange bedfellows? Techno-fixes to solve the big conservation issues in southern Asia“, by Barry W. Brook & Corey J.A. Bradshaw. Here are some details: Abstract The conservation challenges facing mega-biodiverse South and Southeast […]

Depressing climate-related trends – but who gets it?

I saw two particularly depressing trend lines this week. Both were confronting enough to make me stop, sit back and just contemplate. It was not as though these came as a great surprise — I’d been following these data for years. But for some reason, the seriousness of them really struck home like never before. […]

Low intensity geoengineering – microbubbles and microspheres

Guest post by John Morgan. John runs R&D programmes at a Sydney startup company. He has a PhD in physical chemistry, and research experience in chemical engineering in the US and at CSIRO. He is a regular commenter on BNC. A 9-page printable PDF version of this post can be downloaded here. ———————————- Crazy talk […]

The Azimuth Project

In the news recently, there was discussion of using helium balloons for geoengineering, as a method for dispersing aerosols or cloud-nucleation droplets into the atmosphere. (The proposal was critiqued here by George Monbiot). This idea is just the latest in growing field of science-based speculation on active climate system intervention, some of which has been […]

Why population policy will not solve climate change – Part 1

I have given lots of talks on climate change over the last few years. In these presentations, I typically focus on explaining the basis of the anthropogenic climate change problem, how it sits in the context of other human and natural changes, and then, how greenhouse gas emissions could be mitigated with the elimination of […]

What is your energy philosophy?

People seem to like to infer motives. (Perhaps it’s an inherent evolutionary trait, allowing anticipation of your prey’s or predator’s next move?) I find that a lot of people get me wrong about my position on energy and sustainability — often deliberately so, I suspect. So here’s a post to clarify my position, and allow […]

Why pro-nuclear environmentalism has failed when anti-nuclear has succeeded – and how to change this

With George Monbiot on the debating warpath against Greenpeace and in support of nuclear power as a serious mechanism for tackling climate change, and Mark Lynas’ new book on planetary boundaries and techno-fixes, “The God Species“, now out (despite some weird problems on the launch day), it really is time for environmentalists to get serious about starting […]

Open Thread 16

The Open Thread is a general discussion forum, where you can talk about whatever you like — there is nothing ‘off topic’ here — within reason. So get up on your soap box! The standard commenting rules of courtesy apply, and at the very least your chat should relate to the general content of this blog. The sort of things […]

Critique of MIT future of nuclear fuel cycle study

MIT (energy initiative) recently released a controversial and well-publicized report on the future of the nuclear fuel cycle. In it, they argue that there is sufficient uranium to allow ongoing deployment of water-cooled reactors for many decades; they recommend that no far-reaching decision be made yet on the ultimate disposal of the ‘spent’ nuclear fuel […]

Nuclear power and climate change – what now?

I’m currently on a 3-week trip to North America, and will be returning to Australia in mid-June. At the end of my travels I’ll be attending an energy futures conference in Waterloo, Canada (and will write more about that in an upcoming blog). But at present, I’m in Davis, California, and have been visiting Tom […]

What price of Indian independence? Greenpeace under the spotlight

Renewables and efficiency cannot fix the energy and climate crises (part 2)

This post continues directly on from Part 1 (please read that if you’ve not already done so!). I also note the flurry of interest in the new IPCC WGIII special report on renewable energy prospects through to 2050. I will have more to say on this in an upcoming BNC post, but in short, it […]

Renewables and efficiency cannot fix the energy and climate crises (part 1)

The modern world is caught in an energy-resource and climate-change pincer. As the growing mega-economies of China and India strive to build the prosperity and quality of life enjoyed by citizens of the developed world, the global demand for cheap, convenient energy grows rapidly. If this demand is met by fossil fuels, we are headed […]

Nuclear energy challenges for the 21st century

The following post, by Dan Meneley, was originally presented at the 17th Pacific Basin Nuclear Conference Cancun 2010, and is reproduced here with Dan’s blessing (I plan to buy him dinner, as thanks, when I visit Toronto in June). Its contents are highly topical in the context of the current situation in Japan and the debate that […]

Anti-nuclear cartoon book, 1978 – anything changed?

A few weeks ago, Haydon Manning passed me an interesting book from the more dusty section of his shelf. It was called “Nuclear Power for Beginners“, and the edition I have was published in 1978. (If you do a bit of searching, you can still find old copies for purchase). If you’ve read this post […]

Lessons about nuclear energy from the Japanese quake and tsunami

Below is the second piece published on BNC on the lessons learned from the Fukushima Daiichi nuclear crisis. For an earlier perspective, see: Preliminary lessons from Fukushima for future nuclear power plants. Below is a Guest Post by Dr. William Sacks. Bill is a highly experienced physicist and radiologist. He earned a bachelor’s degree in physics from […]

Fukushima Daiichi crisis – April 1 perspective

The Fukushima Daiichi nuclear crisis has moved off the front page of most newspapers, but a lot continues to happen, and the situation remains unresolved. Below I offer some personal perspectives on some of the things that have been widely reported over the last few days, and then I conclude with some official updates. Disclaimer: […]

Fukushima Philosophical Discussion Open Thread

It was suggested in a comment — and I agree — that the previous open threads on the Fukushima Daiichi Nuclear Accident were becoming difficult to read, because they are such a mixture of technical details and philosophical discourse. That is, it’s generally a bad idea to cater to two different audiences in one comment thread. So, […]
