Coastal erosion is here, because of changing weather patterns that bring fierce storms ever more frequently. Look no further than the storm that hit Maine on Dec. 23.

Peter Slovinsky, a marine geologist at the Maine Geological Survey, offers the following resources for homeowners and others who want to learn more.

Slovinsky joined two other panelists and the Monitor’s environmental reporter, Kate Cough, for a virtual discussion Jan. 26 about the effects of the storm and what it illustrates about the effects of sea level rise on Maine’s coasts.
