The current acidification level hasn't been seen for at least 800,000 years, and acidification is coming on 100 times faster than at any point for hundreds of thousands for years. The levels are alarming. The rate of change makes them even scarier, because it so restricts the ability of sea creatures to adapt.
In contrast to the debate that continues about the causal relationship between this or that weather event and human activity, there is no debate about the source of ocean acidification. The change in the chemistry of the ocean is a man-made event, plain and simple, and the consequences of its continuing rise in acidity will belong squarely to us.
It will make for some uncomfortable moments around the dinner table when our children and grandchildren ask, "What did you do in the [climate] war, Daddy?" If we don't recognize the ocean's warning, the first cataclysm from man-made carbon dioxide emissions that will get our attention will be the collapse of the oceans.
If we do recognize the warning, the oceans are ready to be a solution. Power in the tides and waves is there to tap. Offshore wind power is a technology that's ready to go right now, near the great population centers on our coasts, where it's most needed.
