STUDYFINDS - Could aliens be changing their planet’s climate in the same way we are? If so, scientists believe it could make finding intelligent life much easier than we thought. A groundbreaking new study suggests that greenhouse gases could be a telltale sign that aliens are hard at work changing their world’s climate — for better or worse.
Unlike climate change here on Earth, researchers from the University of California-Riverside say the presence of certain gases could signal that aliens are engaging in a process known as “terraforming.” This process modifies a planet to make it more habitable for life.
While we’ve only dreamed about doing this to Mars, what if an advanced alien civilization was already tweaking the climate of a world in their home star system? How would we know? The findings in The Astrophysical Journal zero in on artificial greenhouse gases that are making those exoplanets warmer.
According to UC Riverside astrobiologist Edward Schwieterman and his team, these gases would be a dead giveaway of planetary engineering. These aren’t your run-of-the-mill greenhouse gases like carbon dioxide. We’re talking about super-powered, lab-created chemicals that could rapidly warm up a freezing world. Think of it as a giant global warming bomb that turns cold, uninhabitable planets like Mars into a warm, livable world like Earth within years instead of centuries.
