Oceans Are On The Edge Maybe Might Possibly Of Being Oxygen Starved Or Something

Today’s story of doom

Oceans on edge of being oxygen STARVED due to climate change, researchers fear
THE world’s ocean are at the tipping pint of being starved of oxygen leading to mass sea life extinction which could last a million years, researchers fear.

University of Exeter scientist say the modern ocean is “on the edge of anoxia” – when the oceans are depleted of oxygen. (snip)

She said: “Once you get into a major event like anoxia, it takes a long time for the Earth’s system to rebalance.

“This shows the vital importance of limiting disruption to the carbon cycle to regulate the Earth system and keep it within habitable bounds.”

Of course, this is supposed to play out over the next million years or so, based on things that have happened in the past. Interestingly, the article itself doesn’t necessarily support the apocalyptic headline and subhead, nor does the paper. But, hey, what’s a little scaremongering from the media to spread some awareness?

And they love throwing out the tipping point phrase.

    Didn’t they worry about this about 50 years ago? Seems that it was one of the big worries that never played out.

    Here’s what the actual scientists who conducted the research and wrote the paper concluded;

    Given that the modern ocean is ‘on the edge of anoxia’(12) and observations that the Earth system may take millions of years to regain background function if the ocean is tipped into an anoxic state, it will be critical to manage anthropogenic disruption to the C-cycle and maintain the natural functioning of wildfire-activity in order to regulate the Earth system within habitable bounds.

    It was Albert Einstein who questioned the wisdom of using energy sources that consumed atmospheric oxygen.

    2 C8H18 + 25 O2 → 16 CO2 + 18 H2O

    Fortunately for us oxygen-dependent organisms, O2 depletion is happening less rapidly than CO2 accumulation (thank you green plants)! Every gallon of gasoline burned consumes about 22 pounds of O2 yielding almost 20 pounds of CO2!! But don’t panic, the O2 levels are not directly impacting human health.

    Yes-CO2 is good. The planet greens, with the result being more plants to give off more oxygen.
