"With a business-as-usual emissions scenario, McNeil and his colleague estimate that the Southern Ocean is likely to reach a wintertime tipping point for these creatures when atmospheric CO2 concentrations reach 450 parts per million, versus today’s level of around 383 ppm. That would occur by 2030 and no later than 2038, they estimate. The results appear in the Dec. 9 issue of the Proceedings of the National Academy of Sciences (PNAS)."

This an article in 'The Christian Science Monitor' concerning the rapid increase in global ocean acidification. For those with little interest or aptitude in dry scientific facts, suggested reading the comment by 'Russ (dated: 12-18-08)' at end of article.

Keep this in mind when watching politicians discuss 20% reductions of carbon to 1990 levels, and so forth. They cheat on even these minimal goals, which even if met would not be nearly sufficient. It has to do with life on this planet, boys and girls. Mother Nature will sort this out one way or the other.

If it goes like the ice and some other things are going, this time next year they'll be saying "OMG, we didn't expect this to happen for 20-30 years!" So sorry.

Quoting myself from another post:

"I suggest we just keep on burning as much fossil fuel as we need to maintain and expand worldwide our industrial and consumer lifestyle and watch the results. Why bother worrying about the climate effect. Most of us will be dead of old age before anything significant happens anyway." GregW

That's what they were telling me in High School "Oh, we won't need to worry about it for thousands of years". That turned out to be a few decades. If a person waits until he/she is personally affected, it will be way, way too late.
