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.
