…don’t want no more ceee oooh twooo:
…it has been shown that atmospheric CO2 concentration (up to 90% of global warming) was roughly twice higher in the not too distant past, some 70,000 years ago. What caused CO2 to drop to a low level around 1850? It was primarily due to plankton growing on the surface of the sea where it absorbs CO2. Sinking to the bottom of the sea, it’s eventually trapped in sediments where it turns to oil or gas.
There simply isn’t enough growing on 35% of the Earth’s surface to soak up the excess atmospheric CO2 that we have to contend with.
Plankton, on the other hand, grow on 65% of the Earth, the seas, where it absorbs atmospheric CO2 faster, in greater quantities. and sequesters it for thousands of in the form of oil and gas.
All we need to do is to dust the surface of the ocean with rust !
What prevents us from proceeding? Damn uncertainty. Uncertainty and what’s beyond. And that’s enough for me.
