Runaway greenhouse effect could turn Earth into an uninhabitable hell

A recent study has offered a chilling prognosis for Earth’s future, drawing parallels to the catastrophic scenarios often depicted in Hollywood blockbusters. Researchers have simulated a runaway
greenhouse effect, suggesting Earth could soon become an “uninhabitable hell” similar to Venus.

Runaway greenhouse effect is irreversible
The study authors point out that while carbon dioxide and methane are known greenhouse gasses, water vapor could be the real trigger for a runaway greenhouse effect on Earth.
As the planet warms due to carbon dioxide and methane emissions, water vapor in the atmosphere, resulting from ocean evaporation, exacerbates the greenhouse effect. This creates a vicious cycle where more evaporation leads to more water vapor, trapping even more heat.
“There is a critical threshold for this amount of water vapor, beyond which the planet cannot cool down anymore. From there, everything gets carried away until the oceans end up getting fully evaporated and the temperature reaches several hundred degrees,” said lead author Guillaume Chaverot, a postdoctoral fellow at UNIGE.

There’s also a problem with the Sun. The Earth may no longer be in the “goldilocks region” because the Sun, has grown warmer since life emerged on Earth; as is natural for a “
yellow dwarf,” So, if we succeed in destroying the ecosystem (which looks increasingly likely) it likely won’t come back.
Our planet is being kept cool by the ecosystem itself (i.e. it has been removing greenhouse gases from the atmosphere.) Destroy the cooling mechanisms and…
