The Field Museum’s Approach to Climate Action The Field Museum helps community organizations execute a three-pronged CHICAGO CLIMATE approach to climate CLIMATE ACTION action that links ACTION PLAN PLAN FOR community strengths NATURE with the strategies of the region’s climate COMMUNITY- action plans.
