What's the CO2 concentration vs altitude? I suspect it rises with altitude and so the increase in CO2 does not benefit plants on the surface too much.

Grasslands are about 100 times more productive than jungles for food. That is why the large herds evolved on the African savana when the continent started to dry out 5 million years ago and was replaced by grasslands.

Has anyone seen any studies as to what kind of plants are most efficient in transforming CO2 into O2?

Yes, plankton, and kelp, and resources of vast size, previously not much considered effect. Aquatic Biomes:
Aquatic biomes account for 70 percent of the Earth’s surface and contain the majority of plant and animal life. Aquatic biomes also account for a vast portion of the photosynthesis, and therefore oxygen production, that occurs on Earth. There are two types of aquatic biomes, based on the type of water found in each: marine and freshwater. sparknotes.com

Which brings us to the fascinating topic of Nautilus... yes the undersea miners... which you have to admit is a far, far more fascinating topic than mere climate change... eurekalert.org

But could the deep ocean mining somehow trigger climate change? Well, but, nahh... who cares?

On this thread at least, dollars and rock have subtle but persausive effect of trumping other clatter filled topics that become the darlings of the cocktail literati. Koan and I have gone where few have dared go before, making Slan_the_grey _eminence_and_threadmaster's dark-hooded, unflinching and baleful eyes glaze over when post forays into ever and ever greater and more minutiae filled detail about ever_less_related to_mining thingamajigerae. Which is passing strange cause we are the next thing to professional mining bugs. We just did not want to get too much into one suit about it.. thass all... Pass the whiskey, the cheap french cigarettes. Turn up the nuclear reactor and hand me that copy of the Northern Miner, let's read about them gold prospectors in Yanomami country.. say isn't that where they are cutting down the rainforest? Good thinking, got to see that outcrop. Or has them dictators in Ekwador gots their heads up their keisters and they gone all green on us?
