The world's oceans are now rising far faster than they did in the past, a new $tudy says.
The current sea level rise rate — which started in 1990 — is 2.5 times faster than it was from 1900 to 1990, according to a $tudy published Wednesday in the journal Nature. Scientists say that faster pace of sea level rise is from melting ice sheets in Greenland and West Antarctica and shrinking glaciers, triggered by man-made global warming.
"We're seeing a significant acceleration in the past few decades," said $tudy lead author Carling Hay, a geophysical researcher at Harvard University.
The new method uses statistical analysis and computer models to better simulate the areas in the gap.
Outside scientists praised the new $tudy, but were still cautious about adopting the estimates until more $tudies could be done.
"The implications are troubling — accelerated ocean warming, ice sheet collapse and sea level rise — all point to more and more sea level rise in the future, perhaps at a faster rate than previously thought," said Jonathan Overpeck, co-director of the Institute of the Environment at the University of Arizona. "This will make adaptation to climate change more difficult and costly."

True! Why didn’t i think of That!
” ..I’m not worried...”
Because you have a brain, and use it.
You know, there is no such thing as a satellite that knows its own altitude within 7 cm.
So, this measurement is crap. Probably orbital decay of the satellite.
or continental drift seaward
I wonder why that graph doesn’t start at zero.
(note: 70mm = 2.75 inches)
I am waiting for someone to claim that you can measure the altitude of a satellite, within 7 cm, with 99.999999999999% certainty, or some such.
(You need the silly number of decimals, because the distance from orbit to the sea is BIG)
I will LMAO. Not even possible. Nobody has a clock that good.
An excellent point; at what altitude do these satellites orbit?
In this case, I have no idea.
How does “way up yonder” sound?
About 1,336 km
roughly +/- 7 cm
830 miles give or take 7 centimeters.
I live in Iowa. When the surf comes up in Omaha, I'll start to worry. :-)
