Global sea level rise in the 20th century

As reported by Robert Moore, according to an international research team, the global sea level rise has accelerated in the 20th century compared to the past 2,800 years; Along with earth & planetary professor Bob Koop, many scientist attribute the rise to global warming.

The results used to the researched were collected from two dozen location over the world. They showed that sea level rose an average of 1.5 inches per century until the 1880s, but soon after the rise of industrialization, global sea level rose 5.5 inches. In the year 1993, the level sea reached it’s highest, around one foot per century.

Researchers predict that by the year 2100, sea levels could potentially rise between 11 to 52 inches depending on the trapping or removing of greenhouse gas emissions. In the data collected, researchers looked for salt marshes, single cell organism, mangroves, sediments, corals, lead levels, and other factors that could affect the rise of sea levels.

Contrary to today’s trends, before the 1880s, the sea level rise followed a downward trend. Soon, if the trends continue as predicted, the sea level rise will follow an upward curve due to greenhouse gas emissions addition to the earth. As a result, many coastal communities will face a real threat as sea levels may rise 22 inches. Others study predict a 52 inches sea level rise by 2100. However, many scientists hope sea level rise between 11 and 22 inches by the end of the century with the 2015 Paris climate agreement.
