Something's happening in Antarctica, the biggest iceberg is in the countdown to melt, will there be a global tsunami?

Countdown to the "global tsunami"? Now the network appeared on such a statement, they believe that: with the rise in sea level, after the melting of all the glaciers in the North and South Poles, the water level rises, the coastline disappears, followed by a tsunami will arrive unexpectedly, then it will be a global catastrophe, evolved into a tragic "global tsunami".

The "global tsunami" is an unbelievable disaster, so will it happen or not?

Something's happening in Antarctica, the biggest iceberg is in the countdown to melt, will there be a global tsunami?

Let's first look at a fact at this stage, the other day the largest glacier on Earth, that is, the Antarctic from time to time, the ice shelf collapse, iceberg shedding, and iceberg A-76a has entered the countdown to melting, the speed is accelerating, there is no way to stop it. Iceberg A-76a is part of A-76, a piece that came off the Antarctic glacier and covers an area of 4,320 square kilometers, more than half the area of Guangzhou and twice the area of Shenzhen.

After that, iceberg A-76 continued to fall off, forming three different sizes of super iceberg, respectively A-76a, A-76b, A-76c, and the "hero" of this melting event is one of them A-76a. A-76a has been drifting alone for 2000km since it fell off, and in this In this aimless journey, A-76a did not appear to melt on a large scale, and its mass remained in a stable state, which was unexpected by all.

However, the end was foreordained, and according to the study, A-76a has started to show signs of melting, and at a very rapid rate.

After remaining stable for so long, why did A-76a suddenly accelerate its melting?

If there is one word to describe the A-76a, then "digging its own grave" is the most appropriate for the current A-76a.

From the pictures taken by satellite and the position of A-76a drifting, A-76a has come to the mouth of Drake Passage and made its way to the north. To know the Drake Passage is the grave of all glaciers and icebergs, A-76a drifted to this place by itself, is not equivalent to "suicide"?

The reason why the Drake Passage is said to be the grave of all glaciers and icebergs is mainly because of the Antarctic Circumpolar Current, which separates the Antarctic, and we can understand that it is a barrier to keep the polar temperature in the Antarctic. It is well known that the temperature of the Antarctic is much colder than that of the Arctic, which is also caused by the Antarctic Circumpolar Current, because its presence blocks down the warm air currents, prohibits the warm air currents from entering the Antarctic, and maintains the low temperature environment of the Antarctic.

So a remarkable feature is formed, the further south you go, the less the iceberg will be melted, on the contrary, the iceberg will melt faster as you go north. Therefore, A-76a all the way to the north, is "digging its own grave", and A-76a has no way back.

The disappearance of icebergs like this is a common occurrence, and whenever a huge ice shelf collapses or an iceberg disappears, it causes concern because it is a major event that threatens the survival of humanity, so it is not surprising that after A-76a showed signs of melting, the phrase "global tsunami" appeared on the Internet.

But the consequences of melting icebergs are not yet of the magnitude of a "global tsunami". Tsunamis are usually generated by submarine earthquakes, volcanic eruptions, submarine landslides and other destructive phenomena, of which 80% are caused by earthquakes, 5% are volcanic eruptions, so the location of the tsunami is often caused by the earthquake zone. Obviously, the melting of icebergs is not an earthquake, which does not produce destructive phenomena, and does not form huge waves, but only slowly raises the height of the sea level.

Want to appear the netizens worried about the global tsunami, the probability is relatively low, the general situation can only appear is the Earth appeared huge damage, may be a lot of atomic bombing, or by a huge meteorite impact, the energy generated by these situations may be able to shake the Earth itself, and then a huge disaster.

It is worth mentioning that China has now established a relatively complete earthquake and tsunami monitoring and early warning system, which is able to warn of tsunamis around the world in about 10 minutes. Tsunamis are horrible natural disasters that we have no way to completely solve, except by establishing an emergency system for the night to minimize the damage as much as possible.
