Remember, that huge plankton growth was based on an immediate doubling (from 380 today to 500+ and 700+) ....
Actual temperatures are declining slightly that past ten years, but have increased only .2 degrees since 1900. Ice levels have NOT significantly changed, but have moved (summertime) with winds, and have been the same in winter.
So, what would cause the massive blooms? It - like the supposed acidization of the sea causing the sound propagation change, causing the whales to die - is exaggerated fiction.
Er, uhm, yes.
I said nothing about the alleged role of temperatures and ice levels. I did say, however, that elevated levels of CO2 can and will lead to increased phytoplankton production. That is not fiction.
