ltapia Posted January 24, 2012 Share Posted January 24, 2012 Terrible, this ocean acidification is huge! Life underwater will be in serious danger if it keeps growing and growing! “When Earth started to warm 17,000 years ago, terminating the last glacial period, atmospheric CO2 levels rose from 190 parts per million (ppm) to 280 ppm over 6,000 years. Marine ecosystems had ample time to adjust. Now, for a similar rise in CO2 concentration to the present level of 392 ppm, the adjustment time is reduced to only 100 – 200 years.” From United Academics Link to comment Share on other sites More sharing options...

jimmydasaint Posted January 26, 2012 Share Posted January 26, 2012 I don't mean to be pedantic but I would like to see solid data over the past 50-60 years about ocean acidification. Thanks. Link to comment Share on other sites More sharing options...

jimmydasaint Posted January 26, 2012 Share Posted January 26, 2012 More here: http://www.skepticalscience.com/ocean-acidification-global-warming-intermediate.htm Thanks for the link and the diagram iNow. It is curous that between 2000 and roughly 2005, there is a substantial drop in carbon dioxide air comcentrations and a subsequent rise in pH. I wonder what humanity were doing right at the time and why can't we replicate this trend? Hope you are well mate. Link to comment Share on other sites More sharing options...

I tried to find some charts to reflect that, but "personal disposable income" seemed to match best: But seriously, it looks as if global "recessions" are related to CO2 emissions; not too surprisingly.... ~ ) Link to comment Share on other sites More sharing options...
jimmydasaint Posted January 28, 2012 Share Posted January 28, 2012 (edited) Loved the chart Essay The link between global recession and also carbon dioxide outputs is, no doubt, multi-faceted. However, the global recession would have been in swing about three years now and it would be interesting to read the new figures. However, IMHO, there is a need for a serious re-think about our wasteful, luxury-laden culture with an inappropriate education system. I think it is about time that we start agreeing with the economist Schumacher and start thinking about work with personal meaning and industries with sustainability as a starting point instead of mass manufacturing capacity. Link I don't want to derail the thread so I will look for some more recent references on oceanic acidification.

Time for a Global Perspective! ~ This is the pharaoh's job to keep everything in order. Really I like what you said. With today's sciences we have so much potential for creating heaven on earth, but do we have the discipline to do that? Yea! Jimmy, you are thinking education. I wish we would take time out from the political discussions and talk about education. Education is the most important factor. Well, educated people make much better voters, and conduct themselves better too. Link to comment Share on other sites More sharing options...
