For those concerned about global warming, all eyes are on December's UN climate change conference in Copenhagen. The stakes could not be higher. Almost every new report shows that the climate is changing even faster than the most dire projections of the Intergovernmental Panel on Climate Change (IPCC) in their 2007 report.

Yet from my vantage point, internationally negotiated climate agreements are fast becoming obsolete for two reasons. First, since no government wants to concede too much compared with other governments, the negotiated goals for cutting carbon emissions will almost certainly be minimalist, not remotely approaching the bold cuts that are needed.


And second, since it takes years to negotiate and ratify these agreements, we may simply run out of time. This is not to say that we should not participate in the negotiations and work hard to get the best possible result. But we should not rely on these agreements to save civilisation.

Saving civilisation is going to require an enormous effort to cut carbon emissions. The good news is that we can do this with current technologies, which I detail in my book, Plan B 4.0: Mobilizing to Save Civilization.
