Are we all going to die of ice? Antarctica is melting before our eyes

The problem of global warming is far from new,however, recent studies by American and Dutch scientists make it look at a completely different angle. According to the results published in Proceedings of the National Academy of Sciences, the Antarctic ice sheet in 2017 lost more than 250 billion tons of ice, whereas in 1979 the losses amounted to no more than 40 million tons of ice per year.

Antarctica is already green

In the process of the study, data on 18 were taken into account.Antarctic regions and 176 subglacial plains. Most of the mass loss occurred in West Antarctica, another 20% in the Eastern and Antarctic Peninsula. In the next few decades, the melting of the ice of the Antarctic may add to the rise in sea level to a few meters. If the ice sheet of the Antarctic is completely melted, the level rises to 57.2 meters. And, unfortunately, everything goes to this.

Disturbing and the recent news that the areaAntarctic sea ice at the beginning of this year fell to 5.5 million square kilometers, and this is at least over nearly 40 years of observation. According to scientists, the record will be updated in the summer of this year.

It may seem that there is still a lot of ice, but in factIn fact, the losses are already catastrophic. This is due to climate change, which leads to a steady reduction in the mass and area of ​​Arctic ice.

When studying world temperature, scientists atNASA's participation uses various methods of collecting and analyzing information, analyzing it from more than a thousand weather stations across the planet. Periodic changes in temperature are possible from year to year, and each subsequent year is not necessarily warmer than the previous one, but in each subsequent decade the temperature will certainly be higher.

The fact that the luminosity adds fuel to the firesun increases by 1% every 110 million years. After the flow increases by 10-30%, depending on the state of our atmosphere, we will overcome the critical threshold: the surface temperature will rise to 100 degrees Celsius. That is, at some point, the sun will become so hot that the oceans of the Earth will boil. This will be the ultimate form of global warming: the world will become so hot that there will simply be no more water. Life on Earth will cease to exist, although some intelligent species can still remain in the upper, colder layers of the atmosphere. By this time, the Antarctic ice will have melted long ago.
