It is difficult for many of us to focus on more than one thing at a time. Maybe we are hard-wired that way. But if ever our species needed to evolve such an ability, now is the time. At the same time that we urgently need to decarbonize the global economy, we also need to plan for a very different and much more unstable climate. It’s adaptation time too.
The World Development Report 2010 brings home the urgent need for both decarbonization and adaptation planning. There is a new realism afoot in both the climate change science community and in the development community, brought about by mounting scientific observations of change but also some sobering numbers and projections.
There is, I would say, very little realistic probability of avoiding cumulative emissions that will force the climate system beyond 2°C—unless, of course, there is a significant breakthrough in Copenhagen on mitigation targets, beyond what is presently on the table, and immediate implementation of those targets.
