Erm....

There's an awful lot of evidence that long before mankind or even mammals evolved the atmospheric CO2 levels have been vastly higher than they are now and life positively thrived in the sea and on land.

In periods when vulcanism is high (there's bog all now compared to many periods through geological history) there are more atmospheric pollutants in the carbide, nitride and sulphide families lobbed up in a year than mankind has ever produced since it first discovered fire.

Planet Earth is a dynamic and changable system with, in human terms, very long timescales, taking a miniscule, statistically trivial period like a century and attempting to prove a trend is unbelievably naive and arrogant.

But immensely lucrative...............if you are the ones collecting the "guilt" taxes.

It is quite normal to pump CO2 into an aquarium.

I stand corrected, so it is. But then

The normal biotopes of practically all aquarium plants and exotic fish that you wish to have in your fish tank are use to a slightly acid water that has a pH value of 6 to 7. This is the most desirable environment for your aquarium. But, our drinking water often has a higher pH value that is above 7.

So for the analogy to work, all we need to do is replace the ocean seawater with drinking water..... er....

Just think about all that gold!

Just wait until Yosemite blows.

Yup, not that I hope it does, but when that one goes off there will be a bit of a CO2, NO2 and SO2 spike plus enough particulate crap in the atmosphere to make quite a change.
It will be temporary of course, not even momentary in geological terms, but pretty dramatic and might even lead to multiple extinctions similar to the thousands of similar events that this planet has seen.

There are appears to be some uncertainty with regard to the effects of raised CO2 and ocean acidification. In a worse case scenario a negative feedback loop exists (organisms that absorb CO2 and are normally buried, die or become less successful) and the oceans become more acidic, more die, etc.

Research has already found that corals,[18][19][20] coccolithophore algae,[21][22][23][24] coralline algae,[25] foraminifera,[26] shellfish[27] and pteropods[2] experience reduced calcification or enhanced dissolution when exposed to elevated CO2. The Royal Society of London published a comprehensive overview of ocean acidification, and its potential consequences, in June 2005.[9] However, some studies have found different response to ocean acidification, with coccolithophore calcification and photosynthesis both increasing under elevated atmospheric pCO2,[28][29][30] an equal decline in primary production and calcification in response to elevated CO2[31] or the direction of the response varying between species.[32] Recent work examining a sediment core from the North Atlantic found that while the species composition of coccolithophorids has remained unchanged for the industrial period 1780 to 2004, the calcification of coccoliths has increased by up to 40% during the same time.[30] While the full ecological consequences of these changes in calcification are still uncertain, it appears likely that many calcifying species will be adversely affected. There is also a suggestion that a decline in the coccolithophores may have secondary effects on climate change, by decreasing the Earth's albedo via their effects on oceanic cloud cover.[33]

On a more facetious note. Presumably if the shells of the predated on become less thick or hard, the teeth of predators will become smaller and softer too. Though being sucked by a shark would still be no laughing matter.

Shouldn't we try and stop it? Get a few fire buckets or something?

...and just like the climate change catastrophe, the arguments crumble away.

Excellent! Now we have two to choose from, one from the oldest and most reputable organisation of practising scientists in the world.

And another from the blog of a software engineer.

You can take this democracy thing too far, you know.
