The United Nations chief warned Tuesday that global sea levels have risen faster since 1900 and their relentless increase puts countries like Bangladesh, China, India and the Netherlands at risk and acutely endangers nearly 900 million people living in low-lying coastal areas.
In a grim speech to the Security Council’s first-ever meeting on the threat to international peace and security from rising sea levels, Secretary-General Antonio Guterres declared that sea levels will rise significantly even if global warming is “miraculously” limited to 1.5 degrees Celsius (2.7 degrees Fahrenheit), the elusive international goal.
He warned the Earth is more likely on a path to warming that amounts to “a death sentence” for countries vulnerable to that rise, including many small island nations.
In addition to threatened countries, Guterres said, “mega-cities on every continent will face serious effects, including Cairo, Lagos, Maputo, Bangkok, Dhaka, Jakarta, Mumbai, Shanghai, Copenhagen, London, Los Angeles, New York, Buenos Aires and Santiago.”
The U.N. chief stressed that every fraction of a degree in global warming counts, since sea level rise could double if temperatures rise by 2 degrees Celsius (3.6 degrees Fahrenheit), and could increase exponentially with further temperature increases.
The World Meteorological Organization released data Tuesday spelling out the grave danger of rising seas, Guterres said.
“Global average sea levels have risen faster since 1900 than over any preceding century in the last 3,000 years,” he said. “The global ocean has warmed faster over the past century than at any time in the past 11,000 years.”
According to the data cited by Guterres, the global mean sea level will rise by about 2 to 3 meters (about 6.5 to 9.8 feet) over the next 2,000 years if warming is limited to 1.5 degrees Celsius. With a 2-degree Celsius increase, seas could rise up to 6 meters (19.7 feet), and with a 5-degree Celsius increase, seas could rise up to 22 meters (72 feet), according to the WMO. Read More…
