The sun is going to burn out some day. When that happens, no one will care about ocean acidity.

Re: Ocean acidification due to carbon emissions is at highest for 300m years
#132Can the CO2 be removed from the ocean and broken into C and O2? Is this geo-engineering we can do?
When asking about our ability to geiengineer, remember that we are the once that caused this problem in the first place, and without even trying. Having said that, releasing CO2 is a much easier problem than removing it. As to your proposal, CO2 would decompose into C2 and O2 (with twice as many O2 molecules). Incidentally, C2 is a strong acid [1]. Additionally, breaking CO2 this way would move it to a higher energy…
> Incidentally, C2 is a strong acid
It’s almost impossible to produce a lot of C2 because it reacts with itself and produce some Carbon compound, like an amorphous version of graphite, similar to soot. In this version it can be compressed and buried.
(The main problem with this idea is that the decomposition needs a lot of energy.)

I was confused by this, as well. Given the scale of geologic time, I'd assume they meant 300 million. But a single "M" often means thousand, especially if it's lowercase. So it's confusingly worded.
>But a single "M" often means thousand, especially if it's lowercase. Where? I can find no reference to this.
Most often in financial accounting, though conventionally, in other domains such as academia. Depending on the news outlet, some magazines and papers will also use "M" for thousand and "MM" for million, though that practice is probably dying out in the popular press. And of course, the "M" in "CPM" stands for thousand.
"M" was originally an abbreviation for "mille," which is French for "thousand" (by way of Latin origins). Traditionally speaking, one "M" means thousand, and "MM" means thousand-thousand, or million.

#134This is one more 'climate change' BS. It does not stop fascinate me how self important climate change advocates are. Humans are not geological factor. Besides no one really have time machine to check validity of such claims. And we know very small about actual chemistry of the oceans, especially when it is deeper than SF beaches.

One of the saddest parts of this whole saga is how the carbon dioxide alarmists have hijacked research budgets and public interest which could be spent dealing with legitimate environmental concerns.

#135Is there any reason no one is talking about terraforming seriously yet? What kind of technologies can be used to draw the CO2 out of the atmosphere, how much would it cost to make a difference?
A few people are talking about "geoengineering" approaches, e.g. pumping sulphur dioxide into the upper atmosphere to cause a cooling effect. But such ideas are pretty fringe, I suspect because a) they sound crazy b) that kind of intervention risks serious unexpected consequences.

I would hope the long promised use of carbon in chips and synthetic diamonds would find a use for the carbon instead of burying it.
I was just wondering since it seems like we are not going to be able to reduce usage and undoing it seems like the only hope.

Not at all ... if the acidification is moving some positive feedback loops (and it seems it is) we have much less.
There are almost no positive feedback loops in nature, for the simple reason that they tend to get triggered by random variations and feedback on themself till they reach limit and convert to negative loops.
Try Siberian bog swamps releasing an amount of methane with effects equal to the US yearly emissions.

Very cool I guess we will have to adapt. As current Industrial Complex is too large and unwieldy to react to such thing.
The Industrial Complex is far too small to be even considered among such players as Litosphere and Biosphere.
This is absolutely false. The entire academic world says otherwise with a fantastically high margin of confidence.

I live in Seattle and in just the past few years, beaches which used to be absolutely covered in oysters are now barren because of acidification. And by covered, I mean you need a path through them to walk (they are sharp), and the most difficult thing when picking them was to pick up a single one rather than cluster. This was on the Hood canal for anyone in the area. http://apps.seattletimes.com/reports/sea-change/2…
Local insignificant event.
The appearance of multiple local effects is a clear indicator or a global trned.

Wait, so you're saying that despite the fact that:
- We have accurate measurements of ocean Ph and CO2 concentrations for the past 50 years
- We have a clear understanding of the emissions of CO2 from manmade sources and a record that goes back since the beginning of the industrial age
- We understand the effects of acidification on a large variety of ocean species
- We see a trend of ocean absorbtion of CO2 absolutely consistent with out knowledge of atmospheric chemistry
That means that it's BS?
If you had some evidence to back up the fact as to why a set of multiple thousands of studies in oceanography are flawed when they point out to a singular trend, with a margin of confidence greater than most of the so-called scientific facts that are out there, I wouldn't think what you write is plain denialism.
