Sea level rise isnt just happening, its getting faster
By Chris Mooney June 26 at 11:11 AM
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. Thats 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 under 5 percent of all sea level rise in 1993 to contributing over 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.
The increase in the rate of sea level rise highlights the importance and urgency of mitigating climate change and formulating coastal adaptation plans to mitigate the impacts of ongoing sea level rise, write Xianyao Chen of the Ocean University of China and Qingdao National Laboratory of Marine Science and Technology, and colleagues. Chens co-authors hailed from institutions in China, Australia and the United States.
