“As we put more greenhouse gases into the atmosphere and temperatures rise, we are quickly rewinding the climate clock to climate states not seen in human history,” wrote acclaimed University of Wisconsin paleo-climatologist Jack Williams in an email to The Daily Galaxy. “We can expect that over the next few decades, climates will most resemble those of the warm Pliocene, roughly three million years ago, or perhaps even the hothouse Eocene, 50 million years ago.”

“Mars does like to keep its secrets,” Elizabeth Sklute at the Planetary Science Institute, observed in an email to The Daily Galaxy about packing up the first Martian rock samples as the NASA Perseverance Mission begins its sample return mission. “We sent Mossbauer, and found the oxides were nanophase, and that Mossbauer was inconclusive,” Sklute noted.

“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species. It’s been another fascinating week on our little blue dot from Neil deGrasse Tyson wanting to go ice fishing on Europa to our moon is leaving us, and we can’t stop it.
“Contrary to our first expectations, global climate was not the primary cause of this change in ocean oxygen and nitrogen cycling,” said biogeochemist Emma Kast currently at the University of Cambridge about the planet’s dramatic increase in oxygen 55 million years ago. The more likely culprit? Plate tectonics. The collision of India with Asia — dubbed “the collision that changed the world” by Columbia University geoscientist Wally Broecker, a pioneer in the ocean’s role in climate change.— closed off an ancient sea called the Tethys, disturbing the continental shelves and their connections with the open ocean.
