President Trump's decision to withdraw the United States from the Paris climate change accord is drawing criticism from park advocates and businesses tied to national parks, as well as pledges to reduce carbon footprints and praise for states that are focused on renewable energy.

The changing climate is impacting national park lands in myriad ways, from raising sea levels that will inundate some coastal park units and exposing iconic tree species such as whitebark pines to crippling native and invasive species to altering migration patterns and forest makeup in ways detrimental to wildlife. Regardless of whether you believe climate change is human-driven, change is occurring and impacting the National Park System.

President Trump's executive order Tuesday calling for a ramp-up in coal production from federal lands and a scrapping of President Obama's Climate Action Plan was quickly criticized by conservation and environmental organizations. Unclear, however, was how the move might directly impact national parks and the National Park Service's climate change initiatives.

The National Park Service is preparing an Environmental Assessment in support of a new flexible design strategy for relocating campsites at its Oceanside Campground that are lost or repeatedly damaged by coastal storm events. Several new locations within the developed area on Assateague Island will be considered.
