Sea Level 101

What is sea level, how is it changing, and how can coastal communities plan for the future? These questions and more are answered in this introduction to sea level change and its impacts.

For coastal communities and habitats, the ocean plays an important role in daily life by continually reshaping our coastal environments. As our coasts become increasingly developed, coastal change, and particularly sea level rise has become a pressing issue for many coastal communities.

Sea Level 101 provides an introduction into the how and why of sea level rise, its impacts, and actions that can be taken to address the challenges coastal communities face from rising seas. Whether you are a student, a concerned citizen, or a policymaker, Sea Level 101 is a guiding resource to help you navigate the ins-and-outs of sea level rise.
