Climate Watch: Sea Level Rise Isn’t Just Happening, It’s Getting Faster
In at least the third such study published in the past year, scientists have confirmed seas are rising, and the rate of sea level rise is increasing as time passes — a sobering punchline for coastal communities that are only now beginning to prepare for a troubling future.
What was a 2.2 millimeter per year rise in 1993 was a 3.3 millimeter rise in 2014, based on estimates of the mass changes of a number of key components of sea level rise, such as the melting of the Greenland and Antarctic ice sheets, the study in Nature Climate Change found. That’s the difference between 0.86 and 1.29 inches per decade – and the researchers suggest further sea level acceleration could be in store.
The chief cause of the acceleration was the melting of the Greenland ice sheet, which went from contributing less than 5 percent of all sea level rise in 1993 to contributing more than 25 percent in 2014, the study found. The loss of ice in Antarctica and smaller glaciers over the same time period also contributed to quicker sea level rise. Read More
