The Climate Change in Colorado report (2014)

The Report

The Climate Change in Colorado report (Lukas et al. 2014) is a synthesis of climate science relevant for management and planning for Colorado’s water resources. It focuses on observed climate trends, climate modeling, and projections of temperature, precipitation, snowpack, and streamflow. The 2014 report is a thorough revision and expansion of the 2008 report of the same name, also produced by WWA in partnership with the Colorado Water Conservation Board (CWCB).
