Oceans Are Acidifying Faster Than Ever

Posted March 02, 2012 8:45 AM

From CNET News:

Acidity in the Earth's oceans is increasing more rapidly than any time in the last 300 million years, leading to severe consequences for marine ecosystems.

Drill baby, drill!

This is obviously more propaganda put out by the people who would have us believe that human activity has increased global warming.

We know that can't be, look at how cold it was in Alaska, and how much snow they got this winter.

Let's just ignore it like all the other data that we don't like, and keep making money.

I think it's too late already. We're all gonna die, so what difference does it make?

Negative waves, Moriarity. Negative waves.

Why don't you knock it off with them negative waves? Why don't you dig how beautiful it is out here? Why don't you say something righteous and hopeful for a change?

I told ya it wouldn't last too long.

I'm sorry but a Zebra just can't change his spots overnight.

As there are more people on the planet than at any other time in the last 300 million years, that really isn't surprising. What are you advocating - mass human extinction?

The article seems to raise more questions than it answers. I guess that's no surprise.

Here, the map accompanying the article implies that the ocean region undergoing the largest chemical change is the arctic. (?) Sea water has an average pH around 8. Newly dissolved CO2 will push this closer to a 7. It seems reasonable to think this would occur downwind of the regions where fossil fuels are being burned, not the arctic.

The arctic being colder on average and covered by ice for part of the year, I'd think it would have less dissolved CO2 and therefore be less acidic. If the implication is that warmer temperatures will reduce the ice and therefore increase the CO2 absorption in the arctic, this would seem to be irrelevant with regard to most of the ocean's coral.

Also, there doesn't seem to be any correlation between the use of red dots for warm water coral reefs and purple dots for cold water coral reefs, with the pH scale on the side of the map. Do the coral reefs change the pH of the surrounding sea water; or is this the preferred pH of the coral reefs? Or is this just a poor use of graphing, where the colors used for the reefs have no correlation with pH?

Also, what happens to the other by-products of burning fossil fuels? If CO2 makes the oceans more acidic, where do the chemically opposite by-products go, that would tend to make the ecosystem less acidic?
