Climate change causing global sea levels to rise rapidly every year

The past annual rate of sea level rise - about three millimetres (0.1 inches) per year - may more than triple to 10mm per year by 2100, said the report in the Proceedings of the National Academy of Sciences (PNAS), a peer-reviewed USA journal.

But, Nerem said, "this is nearly certainly a conservative estimate". And if this rate of acceleration continues, by the end of the century sea levels will rise by just over 2 feet.

Steve Nerem, a professor of aerospace engineering sciences at the University of Colorado-Boulder and lead author on the paper, described the phenomena as akin to a "driver merging onto a highway", in a press release accompanying the paper.

He said rising concentrations of greenhouse gases increased the temperature of air and water, causing sea levels to rise in two ways.

That could mean an annual rate of sea level rise of 10 mm/year, or even more, by 2100. The melting of the Antarctica ice sheet, on the other hand, contributed five millimeters to the sea level rise during the same period.

These increases were measured using satellite altimeter measurements since 1992, including the US/European TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellite missions. The end result is a prediction model that matches up very well with forecasts put forward by the Intergovernmental Panel on Climate Change (IPCC) set up by the UN.

La NINA and El NINO and (the opposing phases of the El Nino Southern Oscillation, or ENSO) influence ocean temperature and global precipitation patterns.

Changes in the sea level rise can result to more flooding and erosion.

Thanks to melting ice sheets in Antarctica and Greenland, sea levels have witnessed a rise over past decade or so. They also used so-called tide gauge data to assess potential errors in the measurements.

Pogba starts but no Rashford for Manchester United
Newcastle have been creating chances, it's just that they haven't been successful in converting a lot of them. The result, the club's first home win since October 21, has taken the club two points clear of the drop zone.

This has important implications for the coast: It is much harder to plan for and adapt to accelerating sea level rise than it is for seas rising at a constant rate.

The researchers used data from other scientific missions such as GRACE, the Gravity Recovery and Climate Experiment, to determine what was causing the rate to accelerate.

Co-authors on the study came from the University of South Florida, Nasa Goddard Space Flight Center, Old Dominion University and the National Centre for Atmospheric Research.

"It also demonstrates the importance of climate models in interpreting satellite records, such as in our work where they allow us to estimate the background effects of the 1991 eruption of Mount Pinatubo on global sea level", he added.

Although this research is impactful, the authors consider their findings to be just a first step.

Sea levels might be rising two times faster than we thought, a new study suggests.

Penn State climate scientist Michael Mann, who was not involved with the study, said "it confirms what we have long feared: that the sooner-than-expected ice loss from the west Antarctic and Greenland ice sheets is leading to acceleration in sea level rise sooner than was projected".

Now might be a good time to start taking long-distance swimming lessons-it turns out that humanity is melting the planet even faster than had been previously estimated.
