The Natural Resources Defense Council and the Rocky Mountain Climate Organization released a report August 29 finding that low-lying Atlantic Ocean shorelines are especially susceptible to climate change-caused sea-level rise, flooding, and erosion. The report, Atlantic National Seashores in Peril: The Threats of Climate Disruption, recommends that the country take steps to reduce greenhouse gas emissions 20 percent below current levels by 2020 and 80 percent by 2050, and invest in additional clean, renewable energy sources to reduce emissions.
