There's a hole in the Martian atmosphere that opens once every two years, venting the planet's limited water supply into space — and dumping the rest of the water at the planet's poles.
[...]On Earth, summer in the Northern Hemisphere and summer in the Southern Hemispheres are pretty similar. But that's not the case on Mars: Because the planet's orbit is much more eccentric than Earth's, it's significantly closer to the sun during its southern hemisphere summer (which happens once every two Earth years). So summers on that part of the planet are much warmer than summers in the Northern Hemisphere.
When that happens, according to the researchers' simulations, a window opens in Mars' middle atmosphere between 37 and 56 miles (60 and 90 kilometers) in altitude, allowing water vapor to pass through and escape into the upper atmosphere. At other times, the lack of sunlight shuts down Martian water cycles almost entirely.

Humans weren't satisfied ruining their own atmosphere but had to punch holes in the martian atmosphere with their probes too. The weakened atmosphere is now letting the water leak out. Basically, Mars is crying.

The asshole drinks a lot. He pisses a lot, as a result. What else did you expect?
