The 2019 update report from the Maine Interagency Climate Adaptation Work Group (MICA), a collaboration of eight state agencies, provides an inventory and status update of climate adaptation and mitigation activities by the state and is the second update to the original 2014 Maine Prepares for Climate Change report. This report was developed for the leadership of the departments, agencies, and offices participating in MICA, aiming to increase awareness of adaptation actions taken by the state, improve communication between agencies, and provide recommendations on future work.
