How long till Antarctica has melted completely?

It is impossible to know. Probably many hundreds of years, given the amount of ice there. However, we hope to have slowed global warming down so that all the ice will not melt.

If it all melts, then the human race is probably extinct.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
