NASA predicts sea levels will rise by 30cm by 2050

(ORDO NEWS) — According to a study by NASA‘s Jet Propulsion Laboratories, which analyzed satellite observations over three decades, sea levels along US coastlines could rise by 30 cm by 2050.

One important finding of the study is that the ocean’s rise is uneven. The difference in sea level reaches 20-30 cm in different regions of the oceans.

The oceans are not a flat surface. Its level is different in different regions. And the increase in the level associated with global warming is also different

Sea levels along US coastlines could rise by an average of 30 cm by 2050, according to a NASA study that analyzed satellite observations over three decades.

The Gulf Coast and the southeast of the country will be hardest hit. They are likely to experience increased storms and tidal flooding in the near future.

The smallest rise in sea level is expected on the Pacific coast – in California

The report assumes that over the next 30 years, ocean rise along the US coast will average 25–35 cm for the east coast; 35-45 cm for the Gulf Coast, and 10-20 cm for the west coast.

On the 2021 Earth map, we see sea levels measured by the Sentinel-6 satellite. Regions with red areas have higher than normal sea levels, while blue areas have below normal

On earth and in space

The study used satellite measurements of the height of the sea surface. They were then compared to more than 100 years of National Oceanic and Atmospheric Administration (NOAA) records.

As a result, NASA believes that satellite readings are not anomalous and are fully supported by ground data.

Independent experts agree with NASA findings

David Holland, climate physicist, New York University, commented in an email to Live Science: “The quality of the satellite data is excellent, so the results are reliable.

The study shows that the global ocean is rising, and moreover, this rise is accelerating. The projected rise of 30cm off the Gulf Coast by 2050 is enormous.”

Robert Nicholls, director of the Tyndall Climate Change Centre, UK says: “We have the means to stabilize global temperatures and slow – but not completely stop sea level rise.

It, unfortunately, will continue for centuries. The expert believes that humanity must adapt to such a future: “This may include resettlement in some cases, and raising the level of the coast, and protective dams.

There is no single solution here. If we follow this path, the future will be manageable. But if governments and society ignore these issues today, our future will be a plunge into chaos.”
