Moontanman Posted January 1, 2010 Report Posted January 1, 2010 No Rise of Atmospheric Carbon Dioxide Fraction in Past 160 Years, New Research Finds ScienceDaily (Dec. 31, 2009) — Most of the carbon dioxide emitted by human activity does not remain in the atmosphere, but is instead absorbed by the oceans and terrestrial ecosystems. In fact, only about 45 percent of emitted carbon dioxide stays in the atmosphere. No rise of atmospheric carbon dioxide fraction in past 160 years, new research finds Quote
BrianG Posted January 1, 2010 Report Posted January 1, 2010 Donk has a very perceptive take on that issue here: http://hypography.com/forums/psychology/21668-psychology-sociology-international-global-warming-debate.html#post288860 Does this mean, most of the increasing [ce]CO_2[/ce] in the air is natural?

Michaelangelica Posted January 2, 2010 Report Posted January 2, 2010 Yes and makes the seas acid and dissolves coral like that on the GBR Australia. At some point these natural carbon sinks become untenable or saturated. We have been protected so far by the plant's self-correcting-mechanisms. We can't rely on that forever.

BrianG Posted January 3, 2010 Report Posted January 3, 2010 Donk, would you please post your three possibilities here? Quote

Some historyThe Carbon Dioxide Greenhouse Effect Seriously Michael, do you know of any sea that is acid? Much less acidic enough to dissolve coral? The pH of ocean water is seriously alkaline, pH 8.3 to 8.4 in most open ocean areas, it has a long way to go before it is acidic. I'm not saying this because I think that changes in the oceans are a good thing but I've seen so many of these posts about the oceans becoming acid and i think it's time to point out the oceans are very alkaline, the CO2 level would have to increase to many times it's current value to actually make the oceans acidic. Now having said that I am not arguing for or against global warming, i just want to point out the acidification of the ocean is greatly exaggerated. Having farmed coral at pH values in the 7.0 to 8.0 range, i have to say the ability of coral to grow and reproduce under less than optimum conditions is being greatly understated as well. Again, no it's not a good thing for the ocean to become less alkaline than it is, but it is not acidic! DougF 1 Quote
stereologist Posted January 4, 2010 Report Posted January 4, 2010 Warm water does not dissolve gases as well as cold water. This is why limestone accumulates in shallow warm waters. Deep waters are cold and under saturated in limestone. The waters that support corals do not dissolve away the corals. Quote
