If the Antarctic glaciers melt completely overnight, what disaster will mankind suffer?

If the Antarctic glaciers melt overnight, human beings may be devastated, some countries may be submerged by seawater, some countries may suffer from drought, some countries may suffer from heavy rain, and some countries may be attacked by viruses. In short, once the glaciers melt, all human beings in the world will be unable to escape this disaster, and even human beings may be destroyed. It is really terrible, and even thinking about it will make them afraid. I hope such a thing will never happen.

Antarctic glaciers melt overnight, and when the ice melts, it will turn into water. A lot of water has nowhere to go, and it will flood into some neighboring countries, and then floods will occur in these countries. I think everyone has seen the power of floods, even if they have not experienced it personally, but they have seen it in film and television dramas. Floods can engulf a city in an instant, with terrible power, and almost no one can survive in floods. Many countries are suffering from floods at the same time.

Glacier melting is caused by climate warming. The higher the temperature, the more prone it is to drought, so countries far away from the South Pole may suffer from drought. Drought is also very terrible, because water is indispensable to our human body, and crops will be extinct without water, and even the most basic food can't be guaranteed. This will be a terrible thing, and some coastal areas may have heavy rains, because the temperature is too high, and the evaporated seawater will become.

Moreover, scientists have detected dozens of viruses under the glacier, which we have never seen before. When the glacier melts, these viruses will also come out, and all countries may be infected. This is the disaster that will be brought to us after the glacier melts, so we should prevent this from happening, and what we can do is to take care of our environment from today.
