Sea temperatures changes from Jason-1

Sea temperatures changes from Jason-1

While it seems common sense to me that sea levels would be the same worldwide – the water level in your tub doesn’t change from one end to the other, does it? – apparently that’s not so. According to data from the Jason-1 satellite, sea levels have been rising, but not the same everywhere. Warmer water causes higher sea levels. (I resist the obligatory Al Gore joke that belongs here.)

I first found a reference to this article trying to link it to global warming. The actual NASA article hedges its bets a lot more. Seems to me the oceans are a very complex system, and not any easier to model than the atmosphere…
