“Failure to meet the United Nations’ 2ºC warming limits will lead to sea level rise and dire global economic consequences, new research has warned.”
The world is facing a problem of water extremism. We either have floods or a severe drought that puts human survival at stake. Experts from across the world have good things to say about the advancements in the field of technology, and talk about artificial intelligence or virtual reality, we call it an achievement in the world of science. But, we have failed to manage the natures gift effectively – water resources.
While we are talking about providing access to clean water to millions of people across the globe, we must not forget to talk about the damage we have already created in the name of global expansion that has led to high rise / drop in temperatures.
A study led by National Oceanographic Centre (NOC) discovered that flooding from rising sea level could cost the world a whopping $14 trillion a year by 2100 if we fail to hold the global temperatures below 2 degrees.
Dr Svetlana Jevrejeva, from the NOC, is the study’s lead author. She said: “More than 600 million people live in low-elevation coastal areas, less than 10 meters above sea level. In a warming climate, global sea level will rise due to melting of land-based glaciers and ice sheets, and from the thermal expansion of ocean waters. So, sea level rise is one of the most damaging aspects of our warming climate.”

“We found that with a temperature rise trajectory of 1.5°C, by 2100 the median sea level will have risen by 0.52m (1.7ft). But, if the 2°C target is missed, we will see a median sea level rise of 0.86m (2.8ft), and a worst-case rise of 1.8m (5.9ft)” Dr Jevrejeva said.
“If warming is not mitigated and follows the RCP8.5 sea level rise projections, the global annual flood costs without adaptation will increase to $14 trillion per year for a median sea level rise of 0.86m, and up to $27 trillion per year for 1.8m. This would account for 2.8 per cent of global GDP in 2100.”
“These extreme sea levels will have a negative effect on the economies of developing coastal nations, and the habitability of low-lying coastlines,” said Dr Jevrejeva. “Small, low-lying island nations such as the Maldives will be very easily affected, and the pressures on their natural resources and environmental will become even greater.
“These results place further emphasis on putting even greater efforts into mitigating rising global temperatures.”

So, its upon everyone of us to be responsible as we have undoubtedly reached the danger levels for mismanagement of natural resources.
We only hope the temperatures continue to hold for eternity.
