posted a video titled:
Second Permian Die Off
So I googled it, and this is what I learned…
Scientists have debated until now what made Earth's oceans so inhospitable to life that some 96 percent of marine species died off at the end of the Permian period. New research shows the "Great Dying" was caused by global warming that left ocean animals unable to breathe.
What has been debated until now is exactly what made the oceans inhospitable to life – the high acidity of the water, metal and sulfide poisoning, a complete lack of oxygen, or simply higher temperatures.
New research from the University of Washington and Stanford University combines models of ocean conditions and animal metabolism with published lab data and paleoceanographic records to show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe. As temperatures rose and the metabolism of marine animals sped up, the warmer waters could not hold enough oxygen for them to survive. The study is published in the Dec. 7 issue of Science.
"This is the first time that we have made a mechanistic prediction about what caused the extinction that can be directly tested with the fossil record, which then allows us to make predictions about the causes of extinction in the future," said first author Justin Penn, a UW doctoral student in oceanography.
Important!!!
This now provides a separate and INDEPENDENT way to measure global warming, independent of planetary temperatures. What's more, anyone can do this.
What is the oxygen content of ocean water?
Is it rising or dropping year to year?
Knowing what we do about solar forcing and the coming cold period
We can expect oxygen content to go up.
And that should end completely the Climate Hoax.
