Also the sun seems to be contributing more energy to the earth now.

Yes, you get H2CO3, HCO3- and CO32-. The latter can react with say Mg2+,
Ca2+, Sr2+ etc to form carbonate salts. The more basic the solution is
the more CO32- you have. The more CO2 you have in your water the more
acidic it is (so less CO32-). Anyhow this will not be a big effect on CO2.

Another problem is that a huge amount of CO2 is dissolved the ocean. If
one gets a hotter earth the tempereature in the sea would rise and CO2
will be released (as water dissolves more gas at lower temperatures)
into the atmosphere.

But this if off topic. I'll stop now.

What I would rather see is that they make a good climat model in Ada
than Ada in NMD :-)
