evidence: Scientists have found that global mean sea level—shown in the line plot above and below—has risen 10.1 centimeters (3.98 inches) since 1992. Over the past 140 years, satellites and tide gauges together show that global sea level has risen 21 to 24 centimeters (8 to 9 inches). [...] "With 30 years of data, we can finally see what a huge impact we have on the Earth’s climate," said Josh Willis, an oceanographer at the Jet Propulsion Laboratory and NASA’s project scientist for Sentinel-6 Michael Freilich. "The rise of sea level caused by human interference with the climate now dwarfs the natural cycles. And it is happening faster and faster every decade." [...] "What stands out from the satellite altimetry record is that the rise over 30 years is about ten times bigger than the natural exchange of water between ocean and land in a year," Willis said. "In other words, the human-caused rise in global sea level is now ten times bigger than the natural cycles."
