Water Flows Downhill
I think it was a plumber who first told me that truism. This comes from a blog entry noting that instead of an increase of 3mm/year in the sea-levels, during the past year we saw a decrease of about 5mm. something to do with the change from El Niño to La Niña. I marvel at the ability of being able to measure sea-levels to that degree of precision.
