Hey, Rivero, with every scientist on the planet telling you we could mitigate this, would you still call it a scare tactic to get our money out of us?
Of all the oceans in the world, the North Pacific could be the most vulnerable to acidification.

As the oceans' deepest waters circulate around the globe, they eventually arrive in the North Pacific, where they rise near the surface before plunging deep again to continue their global journey. When the water arrives in the North Pacific, it's already acidic from the carbon produced by decaying organic material during its 1,000-year journey from the North Atlantic through the Indian Ocean and across the Pacific, Feely said.

As it surfaces, or upwells, in the North Pacific, the water absorbs even more carbon dioxide from the air. Cold water absorbs more carbon dioxide than warm water does.

"The older water is in the Pacific, the newer water is in the Atlantic," Feely said. "There's 10 percent more carbon dioxide in the Pacific than in the Atlantic."

Corrosive water 600 to 700 feet deep already has been detected off the continental shelf of Washington state, Oregon and Alaska, Feely said.

"It's butting right up against the coast," he said. "The concern is when it gets to the continental shelf, what it will do to the fisheries."

The increasing acidity can eat away at the shells of crabs, oysters, clams and nearly microscopic organisms known as krill and pteropods. It also inhibits calcification, the process in which these animals rebuild their shells. Without shells, most of the animals probably would die.
Well, would you?
