  • Climate change: looking at uncertainty

Global temperatures are set to rise — but no one is sure by how much. And although this warming will influence variables ranging from biodiversity to economic productivity, exactly how it will do so remains unclear.

Such uncertainty creates difficulties for policy-makers in making decisions based on scientific information.

In this article, Jim Giles reports how two US-based climate researchers are arguing that a more rigorous approach is needed to communicating scientific uncertainty, and that graphical tools should be used to illustrate the origins of such uncertainties.
