ABSTRACT
This chapter addresses Constraint 2—climate change. It discusses three primary areas, some history and background, climate manifestations, the issues and overlays, and a discussion of the overlays for planning for a different and warmer, more turbulent future, or, as the National Academy stated, a future that is inherently uncertain, "but far from unknown." Scientists warn that anthropogenic global warming is real and the resulting climate changes are real and need to be considered in program planning. The impact of the climate changes will be critically dependent on the magnitude of the warming and the rate with which it occurs." Appendix A clearly puts the scientific community in the corner of recognizing that climate change caused by humans is real and ongoing and is serious.
