Science fiction has explored the idea of the end of the world countless times, but recent scientific studies suggest that this scenario may be more than just fantasy. Researchers at the University of Geneva, in collaboration with the French CNRS laboratories in Paris and Bordeaux, have simulated a dangerous scenario.The trickle-down greenhouse effect“, which would make Earth a planet similar to our “evil twin” in the solar system, Venus.
The study reveals a terrifying prospect: the complete evaporation of our oceans and a significant increase in global temperatures. This phenomenon can divide planets into two categories: temperate and warm post-crisis. More alarmingly, this change could occur within a few centuries or even sooner, bringing the Earth to a state where “An unlivable hell.”

Why would Earth become “Hell”?
Venus is a clear example of what can happen. Although similar in size Earth and a rocky composition whose environment is extremely hostile, with an average temperature of 465 °C, high enough to melt lead. A dense Venusian atmosphere, hotter than Mercury’s, shows what could happen if the greenhouse effect gets out of control on our planet.
Contrary to popular belief, water vapor, not carbon dioxide or methane, may be the main driver of this catastrophic change. As the oceans evaporate, the amount of water vapor in the atmosphere increases, preventing heat from escaping into space. This process creates a warming cycle.
When will this catastrophe happen?
The research team outlined three stages in this process: an initial stage of ocean evaporation, followed by a “dry transition” and finally, a “post-disappearance stage” similar to the current Venusian state. This understanding is not limited to predicting the future EarthBut also to assess the habitability of exoplanets.
Another study, the Daily Mail reports, suggests that we are decades away from reaching a climate plateau. An increase of just 2°C above pre-industrial temperatures could trigger uncontrolled global warming, with feedback mechanisms acting like dominoes, leading to a climate. “Greenhouse Earth” The global average is set at 4°C-5°C above pre-industrial levels.
