Some say this is 100 years away.... but ice doesn&amp;#x27;t melt all at once.  I wouldn&amp;#x27;t be surprised if it comes alot sooner and what that world&amp;#x2F;civilization looks like I cannot imagine.&lt;p&gt;And if you have children, then 100 years away sounds very very soon because you know this is the world they will live in.</text></comment>
