LOOK AT WHAT WE STILL DON'T KNOW

I sometimes imagine that there is little left to find out about our planet and then I read something like this and it makes me realise what a lot we still have to learn. The article refers to possibly vast quantities of water under the earth's surface. I wonder what effect all this might have on climate? The reality is - we just don't know.
