And movie fans are well aware that from Armageddon to Tomorrowland, many Hollywood films have already addressed how things will end. the end of the world. Now a study has given us a terrifying glimpse into our planet’s future, and unfortunately it’s not just a Hollywood fantasy.
Researchers Runaway global warming, the massive increase in the temperature of our planet simulation. They came to a very disturbing conclusion, because according to them, the Earth may soon turn into an uninhabitable hell, similar to the planet next to us, To the planet Venus.
What makes it even scarier is that we don’t even need to look far into the future to get to this point. According to scientists, the release of global warming on Earth may occur in a few hundred years, or even earlier.
If the Earth’s oceans evaporated, everything would end
The new study Led by astronomers from the University of Geneva (UNIGE).Next to the laboratories of the French National Center for Scientific Research in Paris and Bordeaux. The paper also warns of the evaporation of the Earth’s oceans entirely, and of a significant rise in global surface temperatures.
Understanding the runaway greenhouse effect is key to appreciating the divergent evolution between Venus and Earth
– They write in the study.
correct A parallel is drawn with Venus, because it has also been called Earth’s “evil twin,” It’s also rocky and about the same size, but has an average surface temperature of 465 degrees.
Even hotter than hell
Because of its dense atmosphere, Venus is hotter than Mercury, even though the latter orbits closer to the Sun. Its surface is hot enough to melt it DrivingIt is covered by toxic clouds of sulfuric acid. Even from Earth, Venus is the brightest thing in the night sky other than the Moon, so it’s somewhat visible It serves as a warning to earthlings about what might happen to the planet.
Although gases such as carbon dioxide and methane are known to cause global warming, according to the study authors, triggering global warming on Earth may actually be caused by water vapor. The world is already warming due to the emission of carbon dioxide and methane, which leads to increased water vapor in the atmosphere due to ocean evaporation. Although many people do not know, water vapor is a natural greenhouse gas.
Water vapor prevents solar radiation absorbed by Earth from returning to outer spaceBecause it traps heat. Thus, global warming increases ocean evaporation, which in turn increases the amount of water vapor in the atmosphere, a rapidly increasing catastrophic spiral.
There is a critical threshold for this amount of water vapor, beyond which the planet cannot cool. From there everything is absorbed until the oceans completely evaporate and the temperature reaches hundreds of degrees
– Tell Guillaume Chaverotlead author of UNIGE.
A three-part process could lead to the end of humanity
With new climate models, scientists have found that even a very small increase in solar radiation would lead to an increase in global Earth’s temperature of only a few tens of degrees. However, this would be enough to start this irreversible process on Earth and make our planet as inhospitable as Venus.
Researchers have identified a three-part process they believe in It can be applied to any planet with an ocean, even planets outside the solar system (To the so-called outer planets).
These are the following:
- First, assuming an initial liquid ocean, it follows The evaporation stage, which enriches the atmosphere with water vapor.
- Second, when the ocean can be considered completely evaporated, a The “dry transition phase” during which the surface temperature rises significantly.
- And finally The development ends with a hot and stable “post-release state.”Which experts estimate has occurred on Venus over the past 700 million years
