Constructed fish pond wall at Kaloko-Honokohau National Historical Park, Hawaii.
Our national parks are a testament to the reality of climate change. Disappearing glaciers, shifting migration patterns for alpine birds, coastal erosion of historic places ... these are many ways that we see the effects of climate change. Our national parks are laboratories for good science and informed management decisions and also for educating the public about how climate change affects us by impacting places we care about. National parks teach us how climate change worked in the past and how it affects us today and can give us insight into ways to protect these special places in the future.
