Charlie Stross:
Sea levels will have risen by at least one, and possibly more than ten metres worldwide. Large chunks of sub-Saharan Africa, China, India, Brazil, and the US midwest and south are going to be uninhabitably hot — that is, too hot for non-GM plants and organisms to survive in during heat spikes, and with heat spikes over 44 celsius at night lasting at least two weeks every year (sufficient to kill off anyone without air conditioning). As 80% of today's human population live within 200Km of a coast, there will have been mass migrations and resettlements: many of today's great cities will be lost. London, New York, Amsterdam, Tokyo, Mumbai — they're all going to be submerged, or protected by heroic water defenses and at comparable risk to today's Venice and New Orleans (both of which will be long-since lost).
