Life, as we understand it on Earth, requires some basic ingredients. Water is one of those. And for years, NASA's succession of robotic missions has been "following the water" on Mars to learn more about the planet's history, including if it ever supported life.
Today, Mars only receives about 43% of the concentrated sunlight that Earth receives from the sun. This means that temperatures on ancient Mars would have struggled to rise above the melting point of water ice. The rocky planets in our solar system -- Earth, Venus, Mercury and Mars -- contain elements that create heat through radioactive decay. These elements include uranium, potassium and thorium.
Through modeling, the scientists found that subsurface melting of thick ice sheets would have led to an abundance of groundwater on Mars. This means that in order for liquid water to have a stable presence on Mars, it would have to be beneath the surface.
Yes, they had great infastructures too right?
So based on this information Global warming or climate change could be directly correlated to the increase in the suns intensity over billions of years? Is that correct? Because I see a lot of news on climate change initiatives from this liberal news network. Huh?
