This finding show the limits to the past's easy assumptions that humanity could always live under the water, if we destroy the atmosphere and so allow future Solar and Cosmic radiation to fry all life living in the air and on the land.

Our atmosphere - from thin top to thick bottom, must be closely monitored and maintained as our best single shield from our world ending up like the hostile Hells that are Mars, Mercury and Venus.....
