Blog - carbon cycle box models (part 2)

I will focus on two-box models and briefly address non-linearity.

and I cant edit any pages right now, so I need someone to look into this.

..but now I tested while being logged into the Azimuth Forum and it works. Is that what makes it work?

How are the spam filters set up?

That's not supposed to matter. Again: please post technical questions in the category Technical, so Andrew Stacey will see them. He doesn't read all the comments in other categories!

I will write about the ocean part of the carbon cycle - not just because it is the largest "fountain" but due to the fact that its complicated to explain and there are several mechanisms i want to address.

Great!

1) Why does introducing more CO2 into the ocean make it more acidic? This is actually quite subtle. I think I'd need to solve a some equations to understand it. We discussed it here. I've never gotten further in understanding this issue, though I could with some work.

2) Why does the CO2 concentration in the Earth's atmosphere increase so much near the end of a glacial cycle? This is even more subtle, and I don't think anyone knows for sure.

sorry i didn't see this until now. This are two questions I'm gonna expand in the 2nd blog. The first is easier and is explained in both Archers book on the carbon cycle and also some of the papers by Sarmiento et.al which I refer to on the Experiments and I'll answer when I've recovered from vacation - actually my last week now-. The 2nd i am sure I read about in Broecker's book "The great ocean conveyor" PUP 2010 - which is actually also a paleoclimate "thriller" :-)

I hope you recover from your vacation soon. Sometimes you need another vacation to recover from a vacation.

Wally Broecker certainly knows how to make things exciting! I think he's the one who invented the term 'great ocean conveyor belt'. However, I think most people now agree that the flow of fresh water into the North Atlantic is less important for the overall global climate than he argued.
