Warning global sea level may increase suddenly

Warming oceans around Antarctica could dramatically increase global sea levels, a recent warning by Australian and New Zealand scientists.

>>>Why is sea level rising faster than forecast?
>>> Sea level rise abnormally

Dr. Nick Golledge of Victoria University (Australia) said they used complex patterns of climate and ice to regenerate the Antarctic ice sheets at the end of the last ice age, when both the ocean and the atmosphere The books all warm up quickly.

The results show that changes in the ocean may cause significant changes to the stability of the Antarctic ice sheet, leading to an increase in global sea level.

The research team - consisting of scientists from Victoria University (Australia), New Zealand Government Institute of Geology and Nuclear Science and New South Wales University (Australia), found that when the oceans around Antarctica became More stratified, or more layers, warm water at a depth will melt the Antarctic ice faster than when the ocean is less stratified.

An impressive example of this process occurred about 14,000 years ago, and led to a sudden increase in global sea level: an increase of nearly 3m in just a few centuries.

According to Dr. Golledge, with 10% of the world's population living in areas less than 10m above sea level, this study 'emphasizes the need to better define the complex relationship between Antarctica and regions. South Sea '.

The World Bank (WB) is worth Vietnam as one of five countries that will be severely affected by rising sea levels.

According to the Center for Coastal Plains and Dykes, the Institute of Water Resources (Vietnam Institute of Water Resources Research), if sea level rises by 1 meter, about 10% of Vietnam's population will be directly affected, about 90 % of the Mekong Delta rice area (Mekong Delta) was completely submerged, 4.4% of the Vietnamese territory was permanently inundated, meaning that about 20% of communes nationwide, 9,200 km of roads were wiped out. .
