I did.Good show.
Did you happen to catch the part about oceanic phytoplankton being responsible for nearly 50% of all global 02?
I was disappointed that they failed to mention that phytoplankton populations have declined by 40%, which means 02 levels are also likely declining by approx 20%..
And as I've attempted to educate you, it corresponds with the rise of CO2 since 1950.. Which is more than just a coincidence..
You say that phytoplankton is declining because of climate change. I say it's because of limitations of critical trace nutrient. This argument is more credible than yours because when those nutrients are augmented, we see immediate growth in phytoplankton.
If your argument was correct, the availability of nutrients wouldn't matter because the climatic conditions (whatever you assert they are) have not reverted to pre-1950 levels. IF climatic conditions, and not nutrient deficiencies, have led to phytoplankton reductions (as you seem to assert), nutrient deficiencies or availability are irrelevant because some other critical climatic/environmental condition required for algal growth is missing (resulting in the 40% decline).
Now.. I have no idea what climatic condition you're referring to, unless it's ocean acidity. But if that were the case, I don't see how adding nutrients like Iron sulphate would be able to over-ride that environmental limitation. On land, if soil is too acid, it's not going to help by adding iron or phosphorus.. The optimal soil PH balance has to be restored first.
