The current study, headed by Bob Kopp of Rutgers University, reconstructed past rates of sea level rise from twenty-four locations around the globe against sixty-six more recent tide gauges.
Studying sea level rise isn’t as simple as measuring the height of the tide in one location. Changing ocean levels have led to rising seas in some areas of the globe and lower ocean levels in others, as well as dramatic shifts in currents and tides.
Based on the reconstructions and comparative research, Kopp says that based on the study, they “can say with ninety-five percent probability that the 20th-century rise was faster than any of the previous twenty-seven centuries.”
The study was published in the Proceedings of the National Academy of Sciences. As Kopp explains, humans and CO2 output are largely to blame for the drastic change in sea level rise, and while some of the damage is likely irreversible, major decisions in policy can start altering the future of the problem.
And it’s not just terrestrial scientists that are studying the alarming change. NASA is also observing the various places where sea levels rise and fall using satellite technology.

While it appears the proof has been laid out before us, it’s hard to believe that there are still many out there who deny the Earth’s changing climate and rising oceans, or at least those who refuse to blame humans for the dramatic differences. What do you think?
