re: Engaging brain

Last time I checked, the estimated CO2 sink capacity of the world's oceans was about 38,000 gigatons. And according to the article, what was the total human contribution since the beginning of the industrial revolution? 500 gigatons?

At some point this starts to sound like another "don't pee in the ocean--it will overflow" scenario.

"Since the beginning of the industrial revolution the world's oceans have absorbed about a quarter of the 500 gigatons of carbon emitted into the atmosphere by humans," Chris Rapley of the British Antarctic Survey said in a statement.


That's 125 gigatons added to a system with a capacity of three hundred times that much. Since the beginning of the industrial revolution. Note how that's worded to make it sound like we're clogging the system with huge amounts. In fact, note how the total capacity of the ocean is not mentioned in the article at all.

The "vast areas of snow melted" in Antarctica melted on the surface for a week, then froze up again.

And frankly, the "human-caused winds" bit is a bit suspect, too.
