Scientists track how climate change made Venus uninhabitable

The researchers explained that Venus's climate was once similar to that of Earth. According to the latest

climate models for moreFor part of its history, the planet has had surface temperatures similar to those of today's Earth. Most likely, the planet also had oceans, rains, possibly snow, continents and plate tectonics. Potentially, life could even exist there.

However, less than a billion years ago, the climate on Venuschanged dramatically due to global warming. The researchers speculate that the intense volcanic eruptions sent enough carbon dioxide into the atmosphere to cause climate change, which vaporized the oceans and halted the water cycle.

This hypothesis, put forward by climate modelers, inspired scientists to search for the details of the process of supposed climate change.

They relied on data from the spacecraftMagellan, which used radar in the early 1990s to observe through dense cloud cover and obtain detailed images of more than 98% of the planet's surface.

Researchers have found that such eruptionsvolcanoes occur once every 20-30 million years. These eruptions can release enough carbon dioxide to cause catastrophic climate changes, including mass extinctions. Moreover, their magma is sufficient to cover the territory of Canada.

Scientists note that such a scenario is possible, but unlikely on Earth - only a few eruptions of this magnitude can lead to such rapid climate changes as on Venus.
