It's worth reading the story. A key factor is that California is a region where winds cause upwellings (think of Florida's odd bouts of cold water in the summer). That deep water already has a lot of carbon dioxide. What with rising atmospheric carbon dioxide, it's making the ocean water acidic. |

the facts:
Pct of co2 in atmosphere went from 0.032% in 1960 to 0.037% in 2009
Not even a tenth of a %...
Don't get me wrong, I am all for ecology, but this hardly seems to be the area to panic about.
Just a way for some to make $$ IMO.
Planting more trees would seem to make more sense than taxing the S#!& out of us anyway. More trees/plants = less co2 and more o2

The news story explains the technical stuff. The California coast is super-sensitive to rising acidity because of those upwellings. The news story is based on a Report published online today in Science. For increasing atmospheric carbon dioxide, the charts showing data from Mauna Loa show just how fast the rise has been since 1959. There isn't very much carbon dioxide in the atmosphere, but it's very active. |

Wedge:
370ppm is a bit old, it's closer to 400 now and from 320 to 400 is a 25% increase in the CO2 of the atmosphere in 50 years. That's really a big jump in just an instant of the biogeologic time scale. Same data, different view. Most of that CO2 is from coal or oil, carbon that's become entrained in the geological cycle, stuff that's cycled naturally over millions or hundreds of million of years. Tress and plants (and humans) are cycled over hundreds or thousands of years so they are not the answer unless you can take their biomass out of the short term cycle, ie: burying the carbon equivalent biomass of all the oil and coal used. I can't see that as a likely solution.
