Climate change effects: the intersection of science, policy, and resource management in the USA

Abstract

AbstractPerhaps no subject is more intriguing and complex than climate change and its effects on ecosystems and their biological communities. Changes in precipitation and snowmelt patterns, sea level rise, increased intensity of storms and wet-weather events, thawing permafrost, changes in vegetation and wildlife composition and distribution, and other effects present significant policy and land management challenges. Scientific modeling and analyses demonstrate that the effects of a changing climate are complex, with high variability over time, space, and species, including effects on benthic organisms. The variable effects of a changing climate complicate decision making, rendering scenario planning, adaptive management, and other management learning tools increasingly important. The very complexity of effects presents particularly difficult challenges for policy makers and resource managers because the available science often is highly uncertain. Thus, other decision support tools are needed to help ma...
