A. How CO2 can be "absorbed" by water B. How CO2 can be an acid
Water can absorb CO2.That's exactly what happens when they make carbonated beverages. The bubbles that come from the drink and bubbles of CO2 being released.
While the CO2 is dissolved in the water it becomes a weak carbonic acid solution.
But none of this is happening to the degree they claim it is and the and while in the ocean, the CO2 becomes part of carbonates (seashells, etc.) and makes life possible for seaweed and phytoplankton, both of which would cease to exist without the CO2.
Thank you, Capt.
Glad to see someone around here has taken organic chemistry...
