Toward a Regional Earth System Model

Numerical models of the climate system continue to evolve and improve, incorporating more and more elements that influence climate. Two important directions of improvement are finer spatial resolution (being able to drill down to smaller and smaller areas), and representations of that most unpredictable aspect of climate: human behavior. These models are called “earth system…

New Accounting Method For Sources of Uncertainty

Climate scientists — including those of us at OCCRI and CIRC— use global climate models to understand the range of possible futures. Dozens of research groups produce hundreds of simulations, which may differ in their greenhouse-gas emission scenarios as well as their starting conditions for each simulation. Thus, interpretation can be challenging. Translating these simulations…
