Detecting Climate Scientists’ Dishonest Fearmongering Regards Loss of Ocean Oxygen

All humans and animals require oxygen to live. So, to evoke public fear, headlines often claimed global warming will cause ocean life to suffocate. They evoke the true but misleading factoid that warmer water holds less oxygen. Thus, rising CO2 will cause the ocean to hold less oxygen leading to suffocation. Dishonestly, they ignore more important dynamics controlling oxygen.
As illustrated (graphic A), ocean surface temperatures reach 25°C to 30°C (red) and rapidly cool to just 5°C (blue) at 1000-meter depths. Yet in contrast to climate crisis narratives, oxygen levels (graphic B) are highest in the warm surface layers and then become severely depleted to their lowest levels at cold 1000-meter depths. Temperature is simply not the oxygen control knob.
The high concentrations of oxygen in the upper ocean layers are produced when photosynthesizing phytoplankton split water molecules. In fact, most scientists have determined that not only do phytoplankton provide oxygen for ocean life, but 50% of all the oxygen we breathe is produced by ocean phytoplankton that’s then released into the atmosphere.
