The report has projected that China will be most severely affected due to sea level rise as some 145 million faced the prospect of getting submerge.
Millions of people living in Indian metros Mumbai and Kolkata are at the risk of getting submerged in the future if climate change triggered sea level rise is left unchecked, a new global report of Climate Central, a US-based research organization, has said. The report, released on Monday, has suggested that at the current pace of sea-rise, coastal cities won’t be threatened in the immediate future. But, maps released with the report show that if a temperature rise of four degree Celsius occurs by 2100 – due to unchecked carbon emissions – then major cities such as Mumbai, London, New York and many others could submerge.
Almost 11 million people are at a risk in Mumbai while globally 760 million people would be affected due to sea level rise. The report also added that such a scenario can be averted if 195 countries, meeting in Paris later in December to reach an agreement to tackle climate change, make a ‘sharp transition’ to clean energy.
Ahead of the Paris summit, 150 nations have submitted their nationally determined plans to tackle climate change and cap global temperature rise to two degree Celsius above the pre-industrial levels. But, the United Nations said last week that even if climate action plans are implemented, greenhouse gas emissions will still be on the rise. The Climate Central report thus asks countries to evaluate the four-degree rise scenario during the Paris summit.
The report has projected that China will be most severely affected due to sea level rise as some 145 million faced the prospect of getting submerge. Followed by China, India would be hit hardest with a population of 55 million exposed to these threats due to a four degree warming and 20 million due to a two degree warming. The sea level will rise by 4.7 metres in the event of a two degree warming and it would be double due to four degree warming.
Climate Central’s report was based on a paper authored by their own scientists Benjamin Strauss and Scott Kulp and Anders Levermann of Germany-based Potsdam Institute for Climate Impact Research published last month in the Proceedings of National Academy of Sciences of the US.
