Summary: TEHRAN (FNA)- Global sea
level rise is not cruising along at a steady rate per year, but rather accelerating a little every year like a driver merging onto a highway.
Scientists analysing 25 years of satellite data discovered that global sea
level is not rising at a steady 3mm per year, as previously thought.
The global sea
level has been rising over the past century and the rate has increased in recent decades.
If the ice sheet in the Aurora Basin melted, global sea
levels would rise more than 3-5 meters (10-15 feet).
The West Antarctic Ice Sheet (WAIS) has seen an acceleration of ice mass loss in recent years, and researchers studying global sea
levels continue to learn more about not only the amount of ice in the region that is melting--and could melt in the future--but also the possible causes.
The report noted that greenhouse gases, global surface temperature, average sea surface temperature and global sea
level were the highest on record.
If the whole of WAIS was to collapse into the surrounding waters, it would raise global sea
levels by as much as 3.
It affects global sea
level because the amount of water on Earth essentially is constant, so when more water is stored as snow or Ice on land, less water is available to contribute to rising seas.
levels could rise by more than eight feet by the end of the century, with many parts of the U.
The first study showed that global sea
level rose faster in the 20th century than at any other time in the last 2,700 years.
Comparing with global sea
level curve the short term sea level fluctuations in the said formation are totally in contrast with the global sea
level curve while the long term sea level changes showing a close matchup.
This loss of ice into the ocean would cause a global sea
level rise of up to five metres if the ice sheet disappeared.
