Action in spite of Uncertainty

This is an excellent piece from the Financial Times about the uncertainty surrounding climate change. It goes to great lengths to spotlight areas of agreement and areas where the evidence is less clear (e.g., it's pretty much a given that we'll experience a 1.5C rise in temps, but not so clear cut on 4C).

If you don't have time to read the whole article, skip to the last paragraph:

Meanwhile, concentrations of airborne carbon increase year on year. Once carbon is in the atmosphere, it can stay there for a century, continuing its warming effect. The problem is that if action is delayed until these areas of uncertainty are resolved, the world may find it is too late.

I've written about this before. The whole point of dealing with climate change is to manage our exposure to risk despite the uncertainty.
