Two Vietnamese granaries will be submerged in the sea after 5 years?

Global warming that most of the impact from humans is causing the ice at the two poles to melt faster than ever. The ice melts so quickly that sea level rises and many coastal plains will disappear.

Ice melted at 2 poles, two Vietnamese granaries will be submerged in the sea after 5 years?

This is not the first time that the Larsen B ice shelf in Antarctica has been broken. In 2002, the US space agency (NASA) recorded a partial breakdown of Larsen B, raising concerns about global warming. It is worth mentioning that the ice shelf has existed for at least 100 centuries, before the brilliant civilizations of humanity such as Egypt, Greece, Persia . But now they are disappearing only in less than 1/4 century.

The rest of Larsen B, according to NASA's calculations, is about 1,600 km2 (equivalent to 80% of Ho Chi Minh City) and is about 500 meters high at the thickest point, there are signs of breaking up.

One of the important points of ice shelves is that they prevent glaciers from mixing into the ocean. Without them, ice from Antarctica would quickly flow into the sea and raise the water level . NASA research figures show that the "flow" of glaciers into Larsen B has been increasing over the years. This is only possible when the glaciers ' output "is more open, which means that the voids below Larsen B are getting more and more, a sign that it is about to break down.

Specifically, three glaciers are flowing into Larsen B are Leppard, Flask and Starbuck. In particular, two Leppard and Flask rivers have been thinning 20-22m in recent years and the speed has increased significantly. Flask River has the fastest " breakthrough " at 700 m / year and 36% faster than in 2012. At the time of 2002, this flow rate is only 1/8 of the current.

CO2 increases record and sea level rise

It is not difficult to imagine why a mass of matter that has existed for hundreds of centuries can disappear so quickly. According to the US Ocean and Meteorological Agency (NOAA), the global average CO2 concentration has exceeded 400 ppm. Meanwhile, the number that environmentalists consider "safe" - 350 ppm has been overcome for quite some time.

Scientists predict that if the entire Greenland ice sheet melted, the sea level would rise by 6 m (the size of a 2-storey apartment). If the entire Antarctic ice sheet melted, the sea level would rise by 60 m (10-storey apartment size). And if all the ice on this planet is melted, the sea will rise to 70 m.

Meanwhile, the majority of human agricultural production is concentrated in the coastal plains. If one of the above happens, even if only Greenland ice sheet, will be a food security disaster with countries that use rice as the main food like Vietnam.
