If you want to understand how climate change threatens national security, look no further than Alaska, where the Arctic is warming three to four times faster than the rest of the world. As it warms, permafrost is thawing, ice is melting and the coast is eroding, threatening critical military infrastructure. 

And that’s just the beginning. Climate change is transforming topography. As ice melts, new shipping routes are opening up, fish stocks are moving north, critical minerals and fossil fuels will be exposed, and global powers like Russia and China want a piece of the pie. 

In this episode, host Kai Ryssdal heads to the top of the world to traverse the frozen terrain that could be the center stage for global conflict. We hitch a ride with the Coast Guard, drop in on training exercises in the frigid Alaskan mountain range and uncover vital military infrastructure that’s falling into the ocean.  How are climate change and national security converging in the Arctic? And is our military ready for it?
