Changing Sanctuaries: How National Marine Sanctuaries are Meeting the Challenges of Climate Change
We published a new series, National Marine Sanctuary Climate Change Impacts Profiles, and are now one step closer to understanding the changes that are already occurring at national marine sanctuaries, the threats these changes pose to wildlife and resources, and how these changes are expected to continue impacting sanctuaries in the future. The profiles represent a review and summary of the best available, most up-to-date science and serve as an early step in understanding how climate change affects national marine sanctuaries and the underwater treasures they protect.
