Under the current climate change trend, can sea water evaporate?

If one day, climate change causes seawater to evaporate, the world of people and other species will really fall into a great crisis.

Scientists have recently made a prediction that as the Sun gradually turns into a giant red sphere, high temperatures and more energy, life on Earth will be extinguished.

Of course this will not happen for millions of years. So far, the Sun has been estimated at 4.6 billion years old and is experiencing the last 5 billion years before becoming a giant red star at risk of swallowing all the surrounding planets, with Can include Earth.

But if that phenomenon really happens, the maximum temperature can cause the oceans to evaporate violently, creating a moist greenhouse effect that is hard to reverse. It is certainly inevitable that the Sun as well as other stars will have to follow the laws of the universe. There are birth and death.

Climate change is also an equally dangerous cause of ocean evaporation.

However, according to a recent study by researchers, climate change is also an equally dangerous cause that the Sun can make oceans "evaporate" in the future, indirectly destroying life. of creatures.

The amount of CO2 emitted into the atmosphere is getting more and more. As a result, the most obvious effects are the phenomenon of greenhouse ants on Earth warming up because they cannot reflect all the heat from the sun. Along with the ground, oceans are also the source of absorbing a large amount of that heat. And if CO ₂ levels reach a certain level, the ocean will be at risk of disappearing.

To simulate the effects of CO2 in the atmosphere, researchers used computers to build a water environment. This model simulates the idea that a planet only covers the whole country. In contrast our Earth now has more than 70% water, the rest is land.

The hypothesis used in the study is that CO ₂ is large enough to retain a large amount of heat in the atmosphere and make all the liquids on the planet evaporate, even escape from the atmosphere and permanently do not return in the form of rain.

The amount of CO2 emitted into the atmosphere is getting more and more.

"Basically, very high CO ₂ saturation can lead to water evaporation and disappearance, " says Max Popp, climatologist Max Popp of Germany, in Germany . disappearing out of space will take place over millions of years, depending on many factors, although this is a long time if viewed from a human perspective. Time scales can change relatively quickly. "

The study published in Nature Communications found that a hypothetical planet is water if there is an amount of CO2 in the atmosphere reaching 1.520 parts per million (ppm), average surface temperature may be At about this temperature, about 57 degrees Celsius. At this temperature, the climate will start to destabilize, disturb and lead to water evaporating into space.

It is on a hypothetical planetary model. But the researchers believe that the same thing could easily happen on Earth, although our climate is more complicated by having other factors such as land and ice blocks at the poles.

It is known that the concentration of CO2 in the atmosphere of the Earth has now surpassed 400 parts per million (ppm).

Very high CO ₂ saturation can lead to water evaporation and disappear.

Popp told the Motherboard page about the condition of the above phenomenon."Preliminary estimates of the amount of CO ₂ needed to turn the Earth into a giant humidifier will need three or four times the figure of 1,520 parts per million (ppm), so that number could be 4,500 or up to 6,000 ppm ".

"The results from the study will still have to wait for a very distant future, up to millions of years to verify. But they will not affect the current climate and in the near future , " Popp added. .

The researchers' findings are particularly significant in shaping the ambition of finding a new settlement for all humanity in distant space.

Climate climates Popp affirmed that many missions have searched for hundreds of planets. However, to find out if they are suitable for life, the most important thing is to answer the question, can those planets maintain the water for a long time?
