California is not part of the Rocky Mountain region, but a recent study of likely climate-change impacts in that state predicted effects similar to those we may get here--and also illustrated how the severity of the impacts likely will depend on what actions we take to reduce the greenhouse gas emissions responsible for climate change.
The study, by 19 scientists, looked at likely climate-change impacts using two different climate models and, for each |

model, two different assumptions about the level of future greenhouse gases: a lower-emission scenario if aggressive actions are taken to reduce emissions worldwide, and a higher emission scenario if emissions are allowed to increase in a business-as-usual fashion.
Under both models, climate change is predicted to have significant impacts, but the degree of the impacts depends on what we do to protect our climate. |
