GLOBAL SEA LEVEL MAY
RISE 50 FEET BY 2300
Owing to continuous emissions of greenhouse gases, increased global average sea-level is likely to rise by nearly 8 feet by the year 2100 and 50 feet by 2300, as per a new study. According to the researchers from Rutgers University, under moderate emissions, central estimates of global average sea-level range from
1.4 to 2.8 feet by 2100 and 6 to 14 feet more by 2300. In addition, with 11 per cent of the world’s population 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, the study found. “There is much that is known about past and future sea-level change, and much that is uncertain. But uncertainty is not a reason to ignore the challenge,” said study co-author Robert E Kopp, Professor from the varsity.
Importantly, sea-level rise varies over location and time, and scientists have developed a range of methods to reconstruct past changes and project future ones.
