Tony Kevin, author of Crunch Time (refer to this BNC guest post), recently published a review of two climate-change-related books in The Age newspaper (Melbourne’s daily broadsheet). Unfortunately, the review only made the print edition — there is no permanent online record. As such, Tony asked me if I would reproduce them here on BNC, […]

How do you dig down to the core of a person’s beliefs? Can you really hope to influence ‘the unpersuadables’ (a term recently coined by George Monbiot)? Is it worth arguing science and empirical evidence with ‘non-greenhouse theorists’ (you know, the really way-out-there kooks, who won’t even acknowledge that CO2 traps and re-emits infrared radiation)?

The previous BNC post, a guest contribution by Douglas Wise, provided an excellent and thorough review of the political and technical issues facing the UK energy scene. Douglas’ post was also timely, because, last week, the esteemed Royal Academy of Engineering released a new 27-page report on this topic. Although useful as a crystal-ball-gazing exercise, the report has […]

If you ask Jim Hansen to name the single most important thing required to avert catastrophic climate change, he’ll say this: don’t burn all the coal (nor unconventional fossil fuels, such as tar sands and oil shales). Ideally, we would also prefer to leave some of the oil, and much of the natural gas, in […]

As reported earlier on BNC, Dr James Hansen is currently in Australia (I had the pleasure of taking him out to dinner yesterday evening). Tonight he’ll be speaking on climate change and energy solutions at a public event at the Adelaide Convention Centre. There is still time to reserve a ticket and come along — […]

The concept of energy return on investment (EROI), often called energy returned on energy invested (EROEI), is a simple and familiar one. Here is the short definition, from the Encyclopedia of Earth. To cite: ———————————————- Energy return on investment (EROI) is the ratio of the energy delivered by a process to the energy used directly and indirectly […]

The last Open Thread has just slipped off the BNC front page, so time to launch a new one. 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 up on your soap box! The standard commenting rules of courtesy […]

The following essay was published today on ABC The Drum’s Unleashed website. It’s a repackaging and honing of some of the key lines of argument that have been developed on BNC by me, my guest posters, and the blog’s many regular commenters. I hope you find it a useful pointer to the way forward — […]
