Historic Sea Level Rise

An international team of researchers has determined that the modern trend of sea level rise began globally as early as 1863, when the Industrial Age began to produce the first surge in greenhouse gas emissions.

Writing in the journal Nature Communications, the scientists say they examined tide records from 36 different regions around the world to find when and where the seas began to rise. They found it first started in the mid-Atlantic region of the United States between 1872 and 1894, and later in Canada and Europe. Sea level rise has mainly been driven by the thermal expansion of the oceans as the world warmed, as well as runoff from melting glaciers and ice sheets.
