650,000 years of evidence on CO2

So, what happens now that we increased the levels of CO2 to values nature has never had to adapt to before?  Without wallowing in the chemistry of the "how", here's the simple result, the ocean absorbs some of the high levels of CO2 and it makes the seas more acidic.   Acid attacks coral, killing it.  Acid attacks and erodes calcium based shells of lobster for example, and crabs, oysters.

I hope you remember my earlier lessons on carbons origin, CO2.  It is constant in the world, the problem is we are digging up and freeing up, and thawing and cutting down billions of tons of it in our wastful use of fossil fuels, forests, bogs, crops.  We are not making more CO2, we are just taking it from it's proper locations in the world, and blowing it right up into our atmosphere, where it reacts with sunlight and other crap we send up to increase the earths heat.
