Mars cannot be terraformed so that we can live there because there is not enough carbon dioxide, scientists reveal

We won't be able to comfortably live on Mars, experts have revealed. Scientists – as well as science fiction fans – have long hoped that we might be able to change Mars so it has an Earth-like atmosphere, allowing us to comfortably live there. Plans to do so have included dropping thermonuclear weapons at the planet's poles – an idea supported by Elon Musk. But there simply isn't enough carbon dioxide on the planet to allow the atmosphere to ever become habitable for humans, according to new research. At best we could achieve only a fiftieth of what is needed, and would only be able to raise the surface temperature by less than 10 degrees Celsius, the study published in Nature Astronomy reveals.
