By 2300, Global Sea Level Might Rise 50 Feet
A study proves that the global average sea-level could rise by nearly eight feet by 2100 and 50 feet by 2300 if greenhouse gas emissions remain high, posing a major risk to coastal populations and ecosystems around the world. From the start of the century, global average sea-level has risen by about 0.2 feet, said researchers at the Rutgers University in the US.
Central estimates of global average sea-level from different analyses range from 1.4 to 2.8 more feet by 2100, 2.8 to 5.4 more feet by 2150 and 6 to 14 feet by 2300, according to the study published in the journal Annual Review of Environment and Resources.
The researchers have stated that with 11 per cent of the world’s 7.6 billion people living in areas less than 33 feet above sea level, rising seas pose a major risk to coastal populations, economies, infrastructure and ecosystems around the world.
It is said that the sea-level rise varies over location and time, and scientists have developed a range of methods to reconstruct past changes and project future ones.
