How many centimeters has the sea level risen in the past 10 years?

Answer 1

"Scientists estimate that sea level has risen about 10 to 25 centimeters over the past 100 years."

Answer 2

10 to 25 centimeters

Answer 3

Sea levels have risen by 200 mm in the past 100 years (8 inches), at the rate of about 2 mm per year. When satellite altimetry began measuring sea levels in 1993 they found the rise was about 3.3 mm per year from 1993 to 2009.

A common error in climate debate is to focus on short term data instead of looking at long time trends. All sea level graphs (as well as temperature graphs) zig zag up and down. Some years sea levels go down, and the oceans cool: other years oceans warm and sea levels rise, from cyclic events like La Niña (cooling) and El Niño (warming). Some people try to argue that a downward zag means the sea level rise has stopped, but the long term trend shows that sea levels are rising.

A:Since 2009 we have seen a reverse and sea levels are declining. In 2010 the decline was 6 mm. As of the most current data, sea level rise is still not yet occurring and the decrease was at a rate of 5mm a year in 2011.

Focusing on true long term data, the normal sea level rise for the past several thousands of years has been about a 2 mm a year increase. It is doubtful that this will change much in the next few thousand years when we view the total average changes. Short term trends, say over only a few deacdes are too short to give us practical information as the previous answer points out.

La Nina and El Nino cycles are due to ocean temperatures and cause land temperature changes. They are not a result of oceans changing temperatures and as a result have nothing to do with sea level changes. They are oscillating water currents that are transferring heat from one location within the ocean to another. Global ocean temps and levels would not change, while localized levels could.

The past several hundred years have seen a fairly consistent 2 mm a year of sea level increase. We did see a spike in sea level rise for a very short time, but the sea level has been declining back to it's 100 year averages again. While no one knows, with any certainty, it is currently on track to stay on it's normal average of another 2 mm a year.

Answer 4

From 2000 until 2009 ocean levels had been rising at about 3 mm (0.118 inches) per year. So that's 3 centimeters (1.18 inches) in those ten years.

A common error in climate debate is to focus on short term data instead of looking at long time trends. All sea level graphs (as well as temperature graphs) zig zag up and down. Some years oceans cool and sea levels go down, other years oceans warm and sea levels rise, from cyclic events like La Niña (cooling) and El Niño (warming). Some people try to argue that a downward zag means the sea level rise has stopped, but the long term trend shows that sea levels are rising.

A:This trend reversed itself in the later part of 2009 though and the past two years have seen over 5 mm a year declines in both years. This year's trend is similar so far. If we look at true long term trends, we do see a 2 mm rise for the past several centuries. This is roughly in line with what we see for the past ten years when we include all data.

Answer 5

On average, the global sea level has risen by about 3.3 centimeters (1.3 inches) in the past 10 years, according to data from the National Oceanic and Atmospheric Administration (NOAA).
