Most ocean life evolved with CO2 levels 500-2000% higher than today. If you are going to be a science reporter, please learn a little science.
Disrupting the Borg is expensive and time consuming!

Steven – Its almost cruel to demolish the UN press release parroting of Black. He’s astonishingly dim and shallow, even by BBC Environment standards.
Here’s his latest disaster:
20 June 2011 World’s oceans in ‘shocking’ decline
Shocking! Really.
Here’s a fine dissection of it: http://www.climate-resistance.org/2011/06/a-deep-sea-mystery.html
I doubt if Black knows anything but what Greenpeace tells him.
Please shave the goatee Black. Mann is doomed.
Cliff’s notes…..
You can’t make anything “more acidic” until you run out of buffer.
You can do that in the lab with CO2, you just keep adding CO2/acid until
you run out of buffer, then the pH will drop.
Buffer is carbonates/bicarbonates
The largest consumer of carbonates and the largest producer of acids in marine environments
is heterotrophic bacteria responsible for nitrification/denitrification/ammonification. The denitrification process is a 10 to 1 carbonate ratio.
Ten pounds of carbonate to one pound ammonia.
In order for ocean acidification to take place, the ocean would need to run out of buffer/carbonates.
When carbonates get too low, denitrification does not take place.
If denitrification stopped, the results would be so obvious no one could have missed it………..
Everything on this planet would have died.
There is no such thing as ocean acidification!
The entire ocean floor is Calcium and most of the shore lines are also. I have over 70 acres of limestone eroding and washing into the ocean to form more limestone for future eons. I used to live in the desert with places where they mined Gypsum that was left there by sea creatures when the oceans had more CO2 than today.
Even claims the ocean is LESS BASE are wild ass guesses because the composition of elements in the oceans are not well mixed.
Thank you. I am a mechanical engineer, but got good marks in chemistry. This whole “man-made CO2 acidifies the ocean” just flies in the face of reason in a way I find offensive. For gosh sakes the oceans of our earth are dynamical systems (much like our atmosphere) and some incredibly tiny addition of an incredibly tiny elemental fraction of the atmosphere (CO2) somehow by some mechanism un-described somehow results in a chemical reaction making seawater acidic is frankly beyond my comprehension but in certain MSM is a given. I say again: The oceans of the earth are a complex dynamical system. How can a tiny change in a tiny mole-fraction gas deafen fish?
We are descending into barbarism.
Greg, we all know the oceans are buffered, you can’t make anything more acidic until you add enough acid to use up all the buffer. Once all the buffer is used up, then the pH will start to fall.
The most common sense example is people have fish aquariums. It’s common for CO2 levels to be 2000 ppm in a house. People monitor the pH in their aquariums and add buffer to keep the pH from falling.
In order for the ocean pH to fall, it would have to run out of buffer.
If it runs out of buffer – denitrification stops
Everything on the face of this planet dies.
Denitrification is a 10-1-5 (carbonate – ammonia – acid)
It’s not possible for CO2 levels to get high enough to put as much acid in the system as denitrification does.
Adding CO2 causes more limestone to form.
Yep, that’s calcium carbonate. The carbon part.
But it doesn’t just form CaCO3.
There’s also magnesium, boron, phosphates, etc
Collectively they are called carbonates.
Ammonification/nitrification/denitrification liberates it again.
You can keep adding an acid/CO2 to a solution, but you can’t lower the pH until you run out of buffer.
Anyone with a fish aquarium or swimming pool knows that.
From what I’ve seen, too much of climate science is high school science.
Organic chemistry and biological chemistry is way over their heads.
Oh, and denitrification is responsible for almost all of the formation of carbonates….not atmospheric CO2.
Atmospheric CO2 enters the system and is sequestered by phytoplankton.
CaCO2 formation is sight specific in sediments.
I believe Nemo was deaf. If you watch the movie, he never listened to his Dad, so it must be true!
If you suddenly change the environment conditions for any living thing sensory overload is one of the results that will be recovered from with time. It is called adapting but the current crop of Climatologists do not know about the real world.
That is a normal youngster’s reaction. I am in my 60s and the wife is always complaining about my hearing problem. I tell her, I do Not have a hearing problem, I have a problem Hearing YOU! 8)
OMG and I thought I was the only one.
