Sea Levels Rise to 16m at Current Carbon Dioxide Levels Even Without Further Global WarmingVijayan Sankar (Author) Published Date : Aug 31, 2019 13:14 IST
Sea levels may soon rise 16m at current carbon dioxide levels even without further global warming, predicts scientists.
Comparing the current carbon dioxide levels to that of geological evidence found in Mallorca caves in Spain, scientists predict sea levels to rise 16 meters. Sixteen meters is 52+ foot, and such a rise in sea level could engulf many parts of the world. The dangerous part than the carbon dioxide level being the same when the sea level was 16 m high, is that this rise is even without further global warming.
Mallorca cave analysis:
Two professors of Florida and Mexico university today published an article in Journal Nature on their finding sin Mallocran cave in Spain. They analyzed the deposits from Arta Cave on the Mallorca island on the western Mediterranean.
From the analysis, they found that the sea produced sea levels, which will serve as a target or standard for future studies of seal level rise. They were seeking answers to how could global warming increase the melting of ice sheets that cover Greenland and Antartica.
They were comparing the past period when climates were warmer than today and the melting of ice sheets due to its effect. They found that at the same carbon dioxide levels of today, the sea level was 16 meters higher than today level some three million years ago.
Also, with an increase of 4 degree Celsius from the current temperature levels, the scientists measured sea levels more than 23 meters above from the current levels.
Yemane Asmerom of University of New Mexico rings the alarm bells:
The scientist rings the alarm bells that if without an aggressive reduction in greenhouse gases into the atmosphere, the sea levels could rise 16 meters. But as per the United Nation estimates they only expect 65 centimetres of sea rise by the end of this century.
But it also admits that it is only a conservative estimate. The last June and July months were recorded as the hottest months on earth.
Will the sea level remain the same or will it raise to 65 cm or 16 m, or 26 m depends on human participation in global warming.
