About ten or fifteen years ago, I got to visit several of the Hawaiian islands. On the big island I saw new land being &quot;created&quot;, live in front of my eyes, as lava flowed into the sea. It just kept coming.<p>All my life I&#x27;d thought of land as essentially permanent, only shaped by man. I realized that this was wrong - sometimes nature shifts into unstoppable mode, and the only thing we can do is to adapt - and&#x2F;or get out of the way.<p>If there were no global warming, the next scheduled move on the Earth&#x27;s climate cycle would be an ice age. I don&#x27;t think that&#x27;s scientifically in dispute? Besides a lot of land going under ice, and the world getting a colder, the sea levels have historically dropped around 400 feet in the mega ice ages. It would be epic.<p>People have survived them in the past, but it&#x27;s certainly something that gets a lot of people moving.
