Could humans have really lived on Venus? According to the World Economic Forum, the idea is at least possible as Venus “was once Earth-like.”
In a report released this week, the WEF concluded that “less than one billion years ago” the planet could have sustained life just as the Earth does today, but is no longer able to because “climate change made it uninhabitable.”
“The planet Venus once likely had surface temperatures similar to present-day Earth, recent modeling has revealed,” the report said.
“It probably also had oceans, rain, perhaps snow, maybe continents and plate tectonics,” it continued. “But Venus’s climate was permanently altered when catastrophic volcanic eruptions released vast quantities of carbon dioxide into the atmosphere.”
Yup — the same climate change that environmentalists on Earth say is being caused and spurred by human activities.
The same climate change that we need to pass the $20 trillion Green New Deal to prevent from happening.
That same climate change ruined Venus’ chance of ever having humans (again?).
“Could Venus’s fate hold stark lessons for us here on Earth?” the report asked.

This hypothesis from the climate modellers inspired Sara Khawja, a master’s student in my group (co-supervised with geoscientist Claire Samson), to look for evidence in Venusian rocks for this proposed climatic change event.
Since the early 1990s, my Carleton University research team — and more recently my Siberian team at Tomsk State University — have been mapping and interpreting the geological and tectonic history of Earth’s remarkable sister planet.
Soviet Venera and Vega missions of the 1970s and 1980s did land on Venus and take pictures and evaluated the composition of the rocks, before the landers failed due to the high temperature and pressure.
Our search for geological evidence of the great climate change event led us to focus on the oldest type of rocks on Venus, called tesserae, which have a complex appearance suggestive of a long, complicated geological history. We thought that these oldest rocks had the best chance of preserving evidence of water erosion, which is a such an important process on Earth and should have occurred on Venus prior to the great climate change event.
To our astonishment these tesserae valley patterns were very similar to river flow patterns on Earth, leading to our suggestion that these tesserae valleys were formed by river erosion during a time with Earth-like climatic conditions. My Venus research groups at Carleton and Tomsk State universities are studying the post-tesserae lava flows for any geological evidence of the transition to extremely hot conditions.
Several people online shredded the tweet, pointing out that it seems to directly defy the narrative that humans are the sole cause of climate change and the dire need for humans to spend trillions to combat it.

This is probably the stupidest tweet on Twitter today. Maybe this week.

The Venusians didn't pass a Green New Deal to prevent climate change, and now look at the planet.

hold up, you telling me climates can change without humans?! https://t.co/ac0VuOaSmD

Doesn’t this prove climate change happens regardless of human intervention? Did the humans on Venus not pay their carbon tax? https://t.co/3GJ0tV3G8s

So…climate change isn’t caused by humans, but occurs naturally? Fascinating. 🤔 https://t.co/EuBrszuWR2

Serves the Venusians right for not divesting from fossil fuels. https://t.co/y0QiWiRnon
