SPECIAL CLIMATE ISSUE: Colorado's climate forecast is more than that—climate projections are also water projections. The state's warming future will likely impact water supply with retimed flows, less runoff, more extreme precipitation and drought events, and water quality impacts. Coloradans are adapting and uniting to prepare for worst-case scenarios. But that's not all, without mitigation on a global scale, scientists expect temperatures will continue to rise. So state residents are also stepping up to reduce emissions in order to stave off the worrisome extremes associated with a high-emissions future.
