This is not good and gratefully its gaining some publicity. Ever hear the Amazon is the lungs of the planet? Well it emits oxygen and binds atmospheric carbon. That is changing to it being a net C02 emitter. Anyway, yeah, the Amazon emits oxygen we need to breath but the largest source of that is actually the oceans. And when the oceans heat, oxygen production goes down, and less oxygen enters the atmosphere. Oxygen levels in our atmosphere are going down and it will get worse.
Note: Arctic News was recently censured by Facebook:
Kevin Hester of Arctic News explains simply:
“"Atmospheric Oxygen Levels are Decreasing and Scripps attribute it to burning fossil fuels. Excluding Phytoplankton seems weird to me. Half of the world’s oxygen is produced by phytoplankton through the process of photosynthesis." [phytoplankton also oxygenates the ocean where they live]
There are other problems:
“Ocean deoxygenation: "Deoxygenated deeper ocean waters produce greenhouse gases such as nitrous oxide, carbon dioxide and methane that may reach the ocean surface and be released into the atmosphere, contributing to further warming" Ocean deoxygenation - resource | IUCN”
“Ocean deoxygenation
The oxygen content of the ocean has declined by around 2% since the middle of the 20th century overall, while the volume of ocean waters completely depleted of oxygen has quadrupled since the 1960s.
Ocean oxygen levels are expected to fall on average by 3–4% by 2100 overall due to climate change and increased nutrient discharges, though the scale of effect seen will vary regionally.
Consequences of ocean oxygen decline include decreased biodiversity, shifts in species distributions, displacement or reduction in fishery resources and expanding algal blooms.
Ocean deoxygenation threatens to disrupt the ocean’s food provisioning ecosystem services.
To slow and reverse the loss of oxygen, humans must urgently mitigate climate change globally and nutrient pollution locally.”

This will result in atmospheric Oxygen levels declining further and faster:
“71% of the Earth's Surface is covered by water. If we cannot stop the oceans from warming then we will lose all life in the ocean and lose all life in the world. Ocean Warming is Global Warming.”
“The Pacific Ocean's oxygen-starved 'OMZ' is growing, new research finds”
