Evidence for early ocean warming and glacier melt was found by a team of scientists, who found that modern rates of sea level rise began in 1863 as the Industrial Age intensified.
The study used a global database of sea-level records to help planners prepare for future sea-level rise. The journal Nature Communications has a study in it.
Sea-level rise is an indicator of climate change. The researchers were able to identify the time when modern rates of sea-level rise emerged above natural variability.
The researchers found that the beginning of modern rates of sea-level rise occurred in 1863 in line with the Industrial Revolution. Modern rates emerged in the mid-Atlantic region in the late 19th century and in Canada and Europe in the 20th century.
The report detailing the rapid acceleration of sea-level rise on U.S. coasts was recently released.
The global rate of sea-level rise from 1940 to 2000 was faster than all previous 60-year intervals over the last 2,000 years, according to the lead author of the study.
The research team used a statistical model to understand the processes driving sea-level change on global and regional scales.
The influence global sea-level rise has had on our planet in the last century is demonstrated by the fact that modern rates emerge at all of our study sites by the mid-20th century.
