Sea levels have been rising steadily for over a century as the ever warmer ocean water expands and the world’s remaining glaciers and ice sheets melt. In fact sea levels are rising twice as fast now as they were a few decades ago. As the NASA chart above shows there have been some ups and downs but nothing in the modern satellite record comes close to the 6 mm drop worldwide last year.
While 6 mm might not sound like a lot, when collected from the surface of all our planet’s oceans it adds up to 26,000 gallons of water per human.
So just where did all this missing water go?
