Could Earth Turn Into The Next Venus?
From what Venus was like billions of years ago, to how that could turn into a greenhouse planet, join us as we explore whether Earth could turn into the next Venus. You all know the words "Global Warming", and over the last year or two especially there's been a lot of pushing to either get active to stop it, or to admonish it and say that it's "not real". Sadly, Global Warming is very real, and it's a very real threat to our planet, and if we don't do things to try and save the planet, it's very possible that we might end up like a certain other planet in our solar system. Mainly...Venus. What about the Venus Theory? If you don't know, Venus is a very hot planet, in fact it's 864 degrees Fahrenheit on average. Which if you didn't know is enough to melt lead and cause problems for other materials as well. At present, that we know of, there is no life on Venus due to both its atmosphere (which is made up of mostly Carbon Dioxide) and its temperatures. So you might be wondering, "How can we end up like Venus when we clearly have a much different type of planet than it?" Well that's the thing, scientists believe that once upon a time, the planet Venus was a lot like the Earth...until something caused it to change for the worse. How and why are they saying this? Well, Venus has been under study for quite some time due to its extreme temperatures and atmosphere, not to mention it's our "twin" planet. So, scientists have been using simulation technology to try and determine what Venus was like BEFORE it was the heat-blasting planet it is now. And they state that between 2-3 billion years ago...it may have been very much like Earth. With temperatures that weren't the in the hundreds of degrees, and maybe even having its own ocean. “Many of the same tools we use to model climate change on Earth can be adapted to study climates on other planets, both past and present,” said Michael Way, a researcher at GISS and the paper’s lead author. “These results show ancient Venus may have been a very different place than it is today.” Now to be clear, the simulations don't say that Venus was an EXACT match to Earth, as Venus as a whole has many different things than Earth. For example, its rotation, Earth rotates on its axis every 24 hours. Venus does it in the course of 117 days. Also, the simulations state that "ancient Venus" was more land-heavy than Earth, and that its oceans were relatively shallow. Not that this would've dissuaded potential life on the planet, but rather it would've been slightly different conditions than Earth in its early days. So, IF this is all true, and IF Venus was very much like Earth in the early billions of its lifetime...what happened? Well, this is where conflicting theories come to pass. Because for the longest time, it was believed that because Venus was closer to the sun, and thus was more exposed to its sunlight, that it was the cause of Venus turning into what we have now. But according to GISS, that's not exactly what happened: “In the GISS model’s simulation, Venus’ slow spin exposes its dayside to the sun for almost two months at a time,” co-author and fellow GISS scientist Anthony Del Genio said. “This warms the surface and produces rain that creates a thick layer of clouds, which acts like an umbrella to shield the surface from much of the solar heating. The result is mean climate temperatures that are actually a few degrees cooler than Earth’s today.” This meant that the sunlight likely WASN'T the main reason that Venus is now a Greenhouse Effect planet. So what was it? What made Venus the burning hot planet that it is right now? Well, according to many, including the Europlanet Society, they think that a massive "global event" caused the planet to get much, much hotter: "It is possible that the near-global resurfacing event is responsible for its transformation from an Earth-like climate to the hellish hot-house we see today." But what was that event? What could've turned Venus from a habitable planet in every sense of the word...to one that honestly just...wasn't? Sadly, we don't know the answer, and that horrifies many people because that means we can't exactly prepare for what may happen if we don't know what happened to our neighbor. However, we can generalize the action and/or event itself. Because at some point in its lifetime, Venus went from doing a balanced absorption and releasing of heat, not unlike what we have here on Earth, to an imbalance. One where heat was absorbed to a great extent than it was being released. "Basically, Venus was in a state of heat stroke — the planet was in a warming state and it couldn't cool down," said Tyler Robinson, an astrobiologist at the University of Washington. Again, how exactly this happened, we don't know, but it is easy to plot how that "heat stroke" affected the planet and turned it into what we have now. First off, the increased heat would have slowly but surely evaporated the oceans.
