Volcanoes may have killed Venus with an escaping greenhouse, and almost Earth as well

What turned Venus into hell?

It could have just been constantly heated by the sun, but new research suggests that volcanoes may have played a role in creating the greenhouse effect.

And the same story of active volcanism almost killed the Earth.

Earth and volcano

How often has the Earth experienced massive episodes of volcanism, and how much have these episodes affected our planet?

To address these issues, a team of researchers investigated the emergence of large magmatic provinces (LIPs), which are huge deposits of magma scattered around the globe.

The only way to make a LIP is to break the earth’s crust. This can happen when tectonic plates diverge or when mantle plumes rise to the surface.

Tons of greenhouse gases are released into the atmosphere during LIP formation, which dramatically changes the climate.

The formation of a single LIP takes about five million years and they have a devastating effect on the climate.

They have even been linked to more mass extinctions than comets or asteroids affecting the Earth’s surface.

Brewing disaster

We only have an incomplete record of VOCs on Earth. This is because our planet is constantly surfacing through plate tectonics.

But even though the current surface of the Earth is only about 500 million years old, clever geologists have been able to find the remains of the GUB, buried deep in the crust.

According to a study recently published in the print run of the journal arXiv, individual LIPs look random.

There is no known cause that could cause the formation of several lips together. It is also believed that a single LIP formation event does not change the climate system forever because several LIP formations have occurred on Earth and we still have a stable climate.

However, one LIP formation can damage the climate by dramatically raising the temperature of the atmosphere through the greenhouse effect.

And some events of LIP formation do coincide with each other by pure coincidence.

Based on geological data, the researchers found that simultaneous events of LIP formation are likely. Many occur within a million years of each other, which is less than the duration of each exposure.

Escaped Venus

Multiple simultaneous events of LIP formation can completely destroy the planet. If too much is emitted at the same time, too much greenhouse gases are released into the atmosphere.

This can cause an escape effect. If the atmosphere contains too much heat, the oceans begin to evaporate.

With more water in the atmosphere it retains even more heat, further heating the oceans. The cycle goes on and on, eventually leading to the “thermal death” of the temperate world.

Obviously, the Earth escaped this fate, but only because of the skin of our teeth, according to research. If too many lips were formed at the same time, our climate could go into overload. Perhaps this is exactly what happened to our home planet Venus.

We see evidence of many extinct volcanoes on Venus, although we do not know how many were wiped out by weathering or plate tectonics.

If Venus felt too many lips at once, it could cause a greenhouse effect that killed the world.

The next step in this study is to try to figure out how many lips are too, and find out where the turning point is.

With the growing interest in Venus and the space probes on the planet to explore this planet, we can open a window into the volcanic history of this planet. If all this together, you can discover the disgusting story of this twisted, exploded world.
