Nothing is as important as climate change

17. There was a challenge to the claim of atmospheric oxygen loss by Bernardo de La Paz

I did read the paper. That's how I knew that your damn OP was badly wrong!

YOU read the paper. The paper is about OCEANIC oxygen, not atmospheric oxygen. You can't point to anything in the paper that says people will asphyxiate or that atmospheric oxygen will significantly deplete. Read the article for comprehension. It is not difficult to tell the difference between ocean and atmosphere.

However he did not seem to recognize the statement early in the paper that said:

The entire ocean -- from the depths to the shallows -- gets its oxygen supply from the surface, either from the atmosphere or from phytoplankton, which release oxygen into the water through photosynthesis.


Climate change has caused a drop in the amount of oxygen dissolved in the oceans in some parts of the world, and those effects should become evident across large parts of the ocean between 2030 and 2040, according to a new study led by researchers at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.

Scientists expected a warming climate to sap oceans of oxygen, leaving fish, crabs, squid, sea stars, and other marine life struggling to breathe. But they had encountered difficulties in determining whether this anticipated oxygen drain was already having a noticeable effect.

"Loss of oxygen in the oceans is one of the serious side effects of a warming atmosphere, and a major threat to marine life," said NCAR scientist Matthew Long, lead author of the study. "Since oxygen concentrations in the ocean naturally vary depending on variations in winds and temperature at the surface, it's been challenging to attribute any deoxygenation to climate change. This new study tells us when we can expect the effect from climate change to overwhelm the natural variability."

The study is published in the American Geophysical Union journal Global Biogeochemical Cycles. The research was funded by the National Science Foundation (NSF).
