What happens if this does not happen? Who will be held responsible for their scaremongering prognostications? Oh, right, they made it 50 years out
Climate change has likely begun to suffocate the world’s fisheries
By 2080, around 70% of the world’s oceans could be suffocating from a lack of oxygen as a result of climate change, potentially impacting marine ecosystems worldwide, according to a new study. The new models find mid-ocean depths that support many fisheries worldwide are already losing oxygen at unnatural rates and passed a critical threshold of oxygen loss in 2021.
How do they know that it’s an unnatural rate? Do they have direct observations and data from previous Holocene warm periods, when there were no fossil fueled vehicles, no ice makers, no washing machines?
The new study is the first to use climate models to predict how and when deoxygenation, which is the reduction of dissolved oxygen content in water, will occur throughout the world’s oceans outside its natural variability.
Computer models again. Which give them exactly the doomy predictions they want.
It finds that significant, potentially irreversible deoxygenation of the ocean’s middle depths that support much of the world’s fished species began occurring in 2021, likely affecting fisheries worldwide. The new models predict that deoxygenation is expected to begin affecting all zones of the ocean by 2080.
We can solve this with a tax, you know. And taking away your freedom, liberty, and life choices.
“Humanity is currently changing the metabolic state of the largest ecosystem on the planet, with really unknown consequences for marine ecosystems,” he said. “That may manifest in significant impacts on the ocean’s ability to sustain important fisheries.”
Both the previous two warm periods were warmer than the current one: did this type of doom occur? It doesn’t appear as if the “study” even bothers.
“The oxygen minimum zones actually are spreading into high latitude areas, both to the north and the south. That’s something we need to pay more attention to,” she says. Even if global warming were to reverse, allowing concentrations of dissolved oxygen to increase, “whether dissolved oxygen would return to pre-industrial levels remains unknown.”
Do they have specific data on those pre-industrial levels, or, simply, computer models and guesses? This isn’t science, it’s a cult.
