Oceans level are likely to rise as much as 1.3 metres by the start of 2100 if the Earth’s surface warms extra 3.5 degrees Celsius, experts warned on Friday.
By there prediction, within the year 2300, when ice sheets covering West Antarctica and Greenland will have shed trillions of tonnes in mass, sea levels will rise till five meters under the same temperature situation.
Around 10% of the world’s inhabitants, or 770 million people, now live on land which is located less than five metres above the high tide line of oceans.
Even if the Paris climate treaty goal of capping global warming beneath 2C is reached which is actually very tough, the ocean watermark could go up two meters by 2300, according to a study.
Earth’s normal surface heat has risen just over 1 degree Celsius after the pre-industrial era, a widely used benchmark for estimating global warming.
The two new projections for both the year 2100 and tear 2300 horizons are significantly higher than those from the UN Intergovernmental Panel on Climate Change (IPCC).
