I don’t pretend to think that I’ve refuted these acid sea scare-stories yet. But here’s where I’m with it right now after arguing with Steve Munn.
I think this ought to be enough to put your minds at rest over another of the leftist-troll-filibusterererererer-alarmist scare-stories.
But always I am aware that a killer-factoid will come out and turn me around on this.
But the reason this barely happens is that the leftist-watermelon-commies aren’t interested in the first place. They will grab anything thats to hand.
Now I aint running down Bill in this thread. I think he put forward a very good question.
I’m only talking about where I am with it right now.
From the Posner-Becker blog.
I don’t play a scientist on TV, and don’t know much about atmospherics and global warming, but I have worked with carbonic acid’s corrosive potential on fancy machinery in a salt-water environment.
I’d like to comment on the argument that an increase in CO2 in the atmosphere will cause massive ‘evolution’ of the ocean environments or a massive die-off of marine life.
I have no financial interest these days in any of this. The numbers come from Wikipedia because I’m lazy, but they sound right.
The atmosphere today contains about 0.035% CO2. If water is saturated with air with 0.035% CO2, as it might be at the surface of the ocean, the corresponding pH is 5.65. A few feet below the surface of the ocean, water is no longer saturated with air, and the pH is higher.
As a datapoint, a typical raindrop is about 93% saturated. Most water has a pH of around 7.0 because carbonic acid, the agent which causes the drop in pH, is unstable.
Try it with a pool testing kit and glass of water if you want.
If the oceans were to magically become saturated with air, which would never happen, and the CO2 concentration in the atmosphere were to triple, to 0.1%, the ocean’s pH would drop from 5.65 to 5.42. Variations of 0.2 in pH are pretty small.
Realistically the variation in the ocean’s pH from a TRIPLING of the amount of CO2 in the air would be, about, roughly, um, zero. This whole thing smells bad.
“If the oceans were to magically become saturated with air, which would never happen, and the CO2 concentration in the atmosphere were to triple, to 0.1%, the ocean’s pH would drop from 5.65 to 5.42.”
But what we really want to know is the rate-of-change…
For example I figure if a species cannot hand a drop of 1 click in 100 years it really doesn’t deserve to live.
I mean a drop from 5.6 to 5.5 in 100 years.
But if the critter can’t adapt to that I’ve just no sympathy for it.
The thing is the alarmist will get some of these critter. They’ll stick them in a lab.
Then they’ll overnight drop the PH from 5.8 to 5.4 and they’ll report that the coral will reduce its growth from between 5% and 30%…….
I…..don’t ….. THINKso?
Then there is the other thing.
The scare stories are contradictory.
In a much warmer world the Ocean will be quits with the CO2 and won’t absorb it. And so the problem doesn’t arise because warm water won’t absorb all the CO2.
And then a third problem that these people point to when you debate with them.
They will tell you that at a certain PH the ocean won’t absorb any more CO2 and that is held to be a catastrophe for yet other reasons.
But now that solves the PH dropping problem then doesn’t it?
See the reason why these guys are always turning out wrong is they aren’t interested in being right in the first place.
They will grab anything that is to hand.
In any case as long as we are very careful and look after that Plankton what develops is a sort of CARBON-RAIN that rains down endlessly to the bottom of the ocean.
Plant-Plankton dies and the organic matter just drops…. Zoo-plankton eats plant-plankton and craps out stuff fairly rich in carbon and that carbon drops…..
Creatures that are deep-sea creatures at night migrate a kilometer up to eat the plankton and other things and like vampires are back down in their dark coffin of deep sea before the dawn.
So in that way potentially the ocean can deal with any amount of carbon you throw at it.
In the end it rains down past the photic-zone and is taken right out of the climatic system entirely for hundreds of millions of years.
So all we really want to know is:
1. Are we looking after our Plankton and
2. What is the rate-of-change.
And the presumption would be that unless there is this massive rate-of-change there isn’t a great deal to worry about.
