Showing results for "Sea Level" in Science

The past fifteen thousand years--the entire span of human civilization--have witnessed dramatic sea level changes, which began with rapid global warming at the end of the Ice Age, when sea levels were more than 700 feet below modern levels. Over the next eleven millennia, the oceans climbed in fits and starts. These rapid changes had little effect on those humans who experienced them, partly because there were so few people on earth, and also because they were able to adjust readily to new coastlines.

Xia, a Pulitzer Prize finalist, investigates the impacts of engineered landscapes, the market pressures of development, and the ecological activism and political scrimmages that have carved our contemporary coastline—and foretell even greater changes to our shores. From the beaches of the Mexican border up to the sheer-cliffed North Coast, the voices of Indigenous leaders, community activists, small-town mayors, urban engineers, and environmental scientists commingle. Together, they chronicle the challenges and urgency of forging a climate-wise future.

The scenario we are facing is scary: within a few decades, sea levels around the world may well rise by a meter or more as glaciers and ice caps melt due to climate change. Large parts of our coastal cities will be flooded, the basic outline of our world will be changed, and torrential rains will present their own challenges. But this is not the first time that people have had to cope with threatening waters, because sea levels have been rising for thousands of years, ever since the end of the last Ice Age.
