The big danger of Global warming is that it shifts liveable areas in three ways. water shortages eg China, India anywhere draining from the Himalayas; more slowly general temperature increases moving productive zones outwards, eg desertification in North Africa and the possibility of Greenland's ice-sheet joining the ocean and raising sea levels.

Water shortages could be solved by desalination and water conservation thankfully California will probably pay for the development; general migration will require the generally richer countries in the north to take more people (or those people will come all at once) and rising water levels: lots of dykes? (this is actually one of the few costs of Global Warming that wouldn't be recuperable and could be v. expensive).

5 paragraphs of how mathematics has higher standards of rigour. Completed by a muddled argument supported only by a quote and apocryphal reports.

The second part is a boring series of reaches that doesn't go anywhere (literally).

I was aware coming in that Yegge's style is to make tenuous metaphors that obfuscate the point more than they elucidate (remember the story about the Kingdom of Nouns) but I was so enamoured by part 1 that I inadvisedly read it nonetheless.
