Interesting, but the first thing I thought of is do they really think they can convince or impose the relocation of all humans who live in the same area as the sun shines on, or half the sphere? After all, when rising tides are discussed, there are populations whom do not want to move even while thinking about the impending changes to their lives.

I like it a lot. But in no way is this a brand new idea as stated in the article.

One reason that I like it, is that I've been peddling the "half the earth should belong to nature" idea for a couple of years now. Not sure where I picked it up originally though. Probably an article linked from HN.

Just drop a https://en.wikipedia.org/wiki/Thermobaric_weapon in Antarctic Ice Sheets. You'll REBOOT the planet.
