Greenland has something like this, too: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Greenland&#x27;s_Grand_Canyon" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Greenland&#x27;s_Grand_Canyon</a>

I remember debating folks about climate change a while back, from the perspective of managing unknown risks. So much of what could happen or what is projected about the influence of Antarctic glaciers on global sea level rise depends on things like subglacial ice flow dynamics, which we simply have no idea about. And now we have evidence for a 1-km deep canyon directing freshwater flows under the ice. It&#x27;s amazing.

It reads like good literature. &quot;a paucity of ... measurements&quot;. The precision of the text belies the grand landscape it describes.

Nice supplemental read for those interested in the &quot;local&quot; &quot;preliminary(?)&quot; effects of climate change on sea level...<p>The Siege of Miami--As temperatures climb, so, too, will sea levels....<p><a href="http:&#x2F;&#x2F;www.newyorker.com&#x2F;magazine&#x2F;2015&#x2F;12&#x2F;21&#x2F;the-siege-of-miami" rel="nofollow">http:&#x2F;&#x2F;www.newyorker.com&#x2F;magazine&#x2F;2015&#x2F;12&#x2F;21&#x2F;the-siege-of-mi...</a>

I read this as Crayon multiple times. Was so excited for a moment.

Thanks to the great efforts of the human race, we will soon be able to visit all the hidden beauty of Antarctica :)
