A two-week international climate change summit opened in Cancún, Mexico, on 29 November. But will the talks make any progress in tackling global warming? Will mechanisms be put in place to ensure that the previously agreed ceiling of 2°C warming is met?
After the largely unsuccessfuly talks in Copenhagen a year ago, hopes are not high. But a likely rise in global temperatures of considerably more than 2°C could have disasterous global consequences. Indeed, new evidence suggests that even a ceiling of 2°C may be too high and that, as temperatures rise towards that level, domino effects will start that may become virtually unstoppable. As Andrew Sims in the Guardian article notes:
This is the problem. Once the planet warms to the point where environmental changes that further add to warming feed off each other, it becomes almost meaningless to specify just how much warmer the planet may get. You’ve toppled the first domino and it becomes virtually impossible to stop the following chain of events. Honestly, nobody really knows exactly where that will end, but they do know it will end very, very badly.
The following podcasts and articles look at the importance of reaching international agreement but the difficulties of doing so.

Questions
- What would count as a ‘successful’ outcome of the climate change talks? Why might politicians interpret this differently from economists?
- What can governments do to internalise the externalities of greenhouse gas emissions?
- What insights can game theory provide into the difficulties of reaching binding climate change agreements?
- What are likely to be the most effective mechanisms for getting people to adapt their behaviour?
- Can nudge theory be used to change our habits towards the environment?
- Explain the use of equity weights in judging the effects of climate change. Are they a practical way forward in devising environmental policy?
