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><parent_chain></parent_chain></comment><story><title>Atlantic Ocean&apos;s Circulation Is Weakest in 1,600 Years</title><url>https://www.scientificamerican.com/article/slow-motion-ocean-atlantics-circulation-is-weakest-in-1-600-years/</url></story>
