Science & Environment CO2 emissions threaten ocean crisisWriting in Science, experts say the oceans are heating, losing oxygen and becoming more acidic because of CO2.
They warn that the 2C maximum temperature rise for climate change agreed by governments will not prevent
dramatic impacts on ocean systems.
And they say the range of options is dwindling as the cost of those options is skyrocketing.
Twenty-two world-leading marine scientists have collaborated in the synthesis report in a special section of Science journal.
They say the oceans are at parlous risk from the combination of threats related to CO2.
It is clear, they say, that CO2 from burning fossil fuels is changing the chemistry of the seas faster than at any time since a
cataclysmic natural event known as the Great Dying 250 million years ago.
They warn that the ocean has absorbed nearly 30% of the carbon dioxide we have produced since 1750 and, as CO2 is a mildly
acidic gas, it is making seawater more acidic.

There goes the little mermaid! Who are these guys?
1. Professor Manuel Barange, director of science at the Plymouth Marine Laboratory
2-22. Unspecified.
Math problem of the day: How many years would it take, at current CO2 emissions,
to lower the avg. ph of sea water (avg. ph = approx. 8.1 I believe) at a 30% absorption rate by 0.1?
Someone has probably published such a number ... or inserted it in a model?It is technically incorrect to describe the oceans as acidifying. ..They would be becoming less alkali. Doesn't a warming body of water give up its co2?? |

Yes and yes .... but what would I know? (Don't answer that.) Remember MB, it's only five months to Paris. Expect more, much more. Seen it before but this time the Pope and Naomi are on board. We're doomed, I tell you, doomed. Things were worse in 1920COP that! |

True, but I'm not sure the journalist really cares ... or perhaps 'acidic' just sounds scarier. I could not immediately find a relationship curve, but multiple papers suggest that the 'pulse' of atmospheric CO2 concentrations is 'likely' related directly to the oceans ... as CO2 is more readily dissolved in cold water and emitted from warm water as a gas or a precipitate. It is also removed by marine organisms. Thus, the spatial balance of warm vs cold surface waters is important. A Google search yielded the following, but I haven't read it. www.earth.ox.ac.uk/~gideonh/reports/Cquestrate_report.pdfI think I read a reference some weeks past that suggested we could continue our hydrocarbon-burning ways for a long time without lowering our ocean's alkalinity by more than a tenth of a point. They may also overstate marine organisms' sensitivity to ph. Some recent papers note corals seemingly thriving in lower-ph micro-environments. |

Soon we'll see an 'old' photograph appear with major carbon emitters marching down Broadway carrying the 'Southern Cross' and singing 'Dixie'! |

The problem for the panicking warmistss and their ocean 'acidification' claims is that the oceans are buffered just a tiny bit (/sarc) by the basaltic and limestone sea beds. It is just not possible to 'acidify' the oceans when there are so many base rocks. |

A full-blown assortment of largely 'alarmist' videos attached to a CNN article covering an Obama administration climate change plan aimed at a large reduction in greenhouse gas emissions from the nation's coal-burning power plants. No surprise that EPA regulations will lead the charge. All the old arguments being re-dressed for the "Last Tango in Paris"! www.cnn.com/2015/08/02/politics/obama-climate-change-plan/ |

that was the NASA made up CO2 video released to show what the new satellite would show but didn't.
So spin spin and spin based on fabrication. Holdren's way forward, he would have fitted very well into a certain group in Europe 1929.
Very sad end to a presidency that could have been a big step forward for all.

Asthma rates (and all auto-immune diseases) are soaring because of the almost sterile world children grow up in especially true of children in the first 18 months of life as their immune systems develop. The gut flora are important too. The EPA is just doing its normal linear interpolation of a correlation rather than real science. Their latest demand on PM 2s is similar - they claim that these can cause almost instant death so coal fired power stations need filtration equipment at vast cost. Face powder has a significant amount of < PM 2s as does baby powder and talcum powders. Funny I can't remember seeing huge death rates from women going to 'powder their noses'  It is all fake |
