A good seminar by Kevin Anderson (former head of the Tyndall Center for Climate Research in the UK), exploring the conflicts between our stated goal of keeping global warming under 2°C, and the actual energy and emissions policies that the developed world adopts:
The same basic information, in a peer-reviewed format Beyond “Dangerous” Climate Change: Emissions Scenarios for a New World, in the Transactions of the Royal Society. Also in a Nature Commentary (paywall).
The basic point he’s making is, the assumptions that are currently going into climate policy discussions are unrealistic, with respect to what’s required to meet a 2°C goal, even 50% of the time. They require global emissions peaks in 2015 and eventually negative emissions, in order to be able to accommodate the 3-4% annual emissions declines that the economists (which he likes to call astrologers) say is compatible with continued economic growth. But a global peak in 2015 is at this point outlandish from China or India or Brazil or South Africa’s point of view. To give them even a tiny bit of breathing room, and treat our historical emissions even somewhat equitably, the developed world has to peak roughly now, and decline at more like 10% per year for decades, and the developing world has to follow our lead shortly thereafter (maybe 2025).
None of this is compatible with exploitation of any unconventional fuels (tar sands, shale gas, etc.). And, he argues, it also isn’t likely to be compatible with reliance on market based instruments, given that we need to implement drastically non-marginal changes to the economy.
