Monbiot -- too late to avoid climate change?

At Monbiot writes

Yes, it is true that mitigation has so far failed. Sabotaged by Clinton(5), abandoned by Bush, attended half-heartedly by the other rich nations, the global climate talks have so far been a total failure. The targets they have set bear no relationship to the science and are negated anyway by loopholes and false accounting. Nations like the UK which are meeting their obligations under the Kyoto protocol have succeeded only by outsourcing their pollution to other countries(6,7). **Nations like Canada, which are flouting their obligations, face no meaningful sanctions.**

I felt very sad and upset reading this article.
