As climate changes, dynamic coastal regions are experiencing a wide range of impacts. Sea levels, ocean acidification, sea surface temperatures, ocean heat, and ocean circulation have all been changing in ways unseen for thousands of years. Arctic sea ice melted significantly more during summers in the last 30 years, and storms are intensifying. Coastal ecosystems stand to be damaged, and coasts will likely erode from rising sea levels, intensified storm surges, and flooding that climate change may amplify. Coastal communities will need to prepare adaptation strategies to cope, and many who live or work in coastal regions are wondering what climate change might mean for them. This module provides an overview of the impacts coastal regions are experiencing and may continue to experience as a result of Earth’s changing climate. A video series within the module demonstrates effective strategies for communicating climate science.
