Sea and ocean level rise is a tipping point of particular concern to climatologists.
Nationalgeographic.co.id – International scientific team including researchers from Rutgers University found that sea level rise the modern age began in 1863. At this time, the industrial age was deepening and intensifying, coinciding with evidence of early warming oceans and melting glaciers.
The details of their analysis have been described in prestigious journals Nature Communication under the title “Time of emergence of modern rates of sea level rise by 1863.”
The study, which uses records from the Global Sea Level Database over the past 2,000 years, will help local and regional planners prepare for future sea level rise.
Sea level rise is an important indicator of broader climate change. By identifying times when modern rates of sea level rise appear to be above natural variability, researchers can identify the onset of periods of significant climate change.
Climate change refers to long-term changes in temperatures and weather patterns. This change can be natural.
But since the 1800s, human activity has been a major driver of climate change, particularly by burning fossil fuels (such as coal, oil and gas) to produce heat-trapping gases.
Examining records from around the world, researchers found that globally, the current rate of sea level rise occurred in 1863, alongside the Industrial Revolution.
At that time, industrial growth intensified, at the same time as it coincided with signs of early warming of the oceans and melting of glaciers, according to the study.

Around 1863, industrial growth intensified.
At individual sites in the United States, modern sea level rise occurred earliest in the mid-Atlantic region in the mid to late 19th century, and later in Canada and Europe, appearing in the middle of the 20th century.
This study is particularly timely given a recently released report by NOAA detailing the rapid acceleration of sea level rise on the US coast. NOAA or National Oceanic and Atmospheric Administration (in English: National Oceanic and Atmospheric Administration) is the scientific laboratory agency of the United States Department of Commerce.
