The Real Reason Sea Levels Are Rising (And It's Not Ice Melting)

 Take a walk with me through an ancient, verdant land. The colors and aroma of the entangled fauna are so vivid that it takes you a while to notice something isn't right. 

It's all quiet. The near absence of birds and mammals is the only sign that this land is dying, its fate sealed by the end of an ice age—waters are rising. The lush landscape beneath your feet will soon be 30 meters below the surface of the Pacific.

Any species able to migrate have escaped to continue their fight for survival in a warming, shrinking world. Those rooted in place are left to perish. What is happening here? What we can learn from the history recorded deep in the melting polar ice is of vital importance, because right now, it's happening again.

What is causing the ice caps to melt in the present? How will it affect the most powerful climate systems on Earth? And what hidden dangers does the ice contain?

I'm Alex McColgan, and you are watching Astrum. Join me today as we explore what makes ice such an interesting and crucial feature of our planet, and imagine a future, wetter Earth, one whose existence may already be predetermined.

The Pentagon is "engaged with industry on a near-daily basis to gauge needs and provide reassurance that the international community is there to help with safe passage," Air Force Lieutenant Colonel Bryon McGarry, a DoD spokesperson for the Middle East and Africa, told the news outlet.
