🌊Coastline shapes are temporary and have changed over thousands of years due to natural processes.
🌍Earth's coastlines are currently stable due to a relatively stable climate period after the last Ice Age.
❄️Glacier melting and rising sea levels are causing significant changes to coastlines and threatening coastal cities.
🌊Low-lying regions, such as the Florida Keys and Pacific island nations, are especially vulnerable to rising sea levels.
🌍Human activities and climate change are rapidly altering coastlines, posing a threat to civilization.
