Drying and Greening of the West?

Study suggests climate change is expected to increase plant foliage while simultaneously enhancing dry season water stress in the American West.

Northwest Climate Recap

As the fall rains return, let’s not forget that we just had one very hot summer. We give you the numbers in this Northwest Climate Currents.

Back to the Futures

What the Ambitious Integrated Scenarios Project Says About the Northwest Under Climate-Change; How Do Climate Models Work; and What the Heck is Downscaling Anyway?

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…

Connecting Causes and Impacts of Climate Change

Here’s what we know about climate change in a nutshell: Human influence on the climate system is clear Recent climate changes have had widespread impacts on human and natural systems Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive…
