To What Extent is Sea Level Rise Caused by Human Activity?

Global sea-level rise began accelerating ‘30 years earlier’ than previously thought.

Global sea-level rise began to accelerate in the 1960s, 30 years earlier than suggested by previous assessments, a new study finds.

The study, published in Nature Climate Change, introduces a new technique to more accurately determine historical global sea levels by combining two different statistical approaches.

It was found that the southern hemisphere, home to many developing small island nations, experienced the majority of the observed sea-level rise, lead author Dr. Sönke Dangendorf tells Carbon Brief.

22-year Sea Level Rise

This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1 and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches….
