They came, they saw, they agreed once again to do what none of them seem prepared to actually do. Such was the result of climate discussions at the G8 meeting this week in L'Aquila, Italy. The eight nations agreed to limit global warming to 2 degrees C, but failed to agree on any substantive measures that may actually enable such a target to be achieved. I seem to recall that the world agreed to avoid 'dangerous' climate change back in 1992 under the United Nations Framework Convention on Climate Change. Almost 20 years later, governments continue to reiterate that intent, yet don't actually take the steps necessary to bring such intent to fruition. Meanwhile, as argued here by RealClimate and here by yours truly, it's important to bear in mind that all manner of things can still go wrong with the Earth system at less that 2 degrees of warming. Adaptation anyone?
