Rapid Asia–Europe–North America geographic dispersal of earliest Eocene primate Teilhardina during the Paleocene–Eocene Thermal Maximum

by T. Smith et al., July 25, 2022 in PNAS


True primates appeared suddenly on all three northern continents during the 100,000-yr-duration Paleocene–Eocene Thermal Maximum at the beginning of the Eocene, ≈55.5 mya. The simultaneous or nearly simultaneous appearance of euprimates on northern continents has been difficult to understand because the source area, immediate ancestors, and dispersal routes were all unknown. Now, omomyid haplorhine Teilhardinais known on all three continents in association with the carbon isotope excursion marking the Paleocene–Eocene Thermal Maximum. Relative position within the carbon isotope excursion indicates that Asian Teilhardina asiatica is oldest, European Teilhardina belgicais younger, and North American Teilhardina brandti and Teilhardina americana are, successively, youngest. Analysis of morphological characteristics of all four species supports an Asian origin and a westward Asia-to-Europe-to-North America dispersal for Teilhardina. High-resolution isotope stratigraphy indicates that this dispersal happened in an interval of ≈25,000 yr. Rapid geographic dispersal and morphological character evolution in Teilhardina reported here are consistent with rates observed in other contexts.

‘A Significant And Robust Cooling Trend’ In The Southern Ocean From 1982–2020 Defies Climate Models

A new study reports there has been a -0.3°C cooling in the Southern Ocean since 1982 per multiple observational data sets. The authors detail the “failure of CMIP5 models in simulating the observed SST cooling in the Southern Ocean.”

The Southern Ocean is today about 1-2°C colder than it has been for nearly all of the last 10,000 years (Shuttleworth et al., 2021, Civel-Mazens et al., 2021, Ghadi et al., 2020).

If you want proof of mainstream media manipulation and agenda driving drivel, you need look no further than the “official” reporting of the Greenland ice sheet–the poster child for anthropogenic global warming. If today’s intensifying energy crisis wasn’t rooted in said obfuscations, all of this would be laughable.

Impressive surface mass balance (SMB) readings –a calculation to determine the ‘health’ of a glacier– have been posted across the Greenland ice sheet all season. But the cherry, at least for me, is taken by Saturday’s record-smashing 7 Gigaton GAIN–particularly when you consider the glacier should be losing mass at this time of year.

The MSM appears to love dumb, decontextualized headlines to advance their AGW narrative. So here’s one for them:

Greenland’s Recent SMB Gains Enough To Bury Central Park, New York City Under 7,833 Feet Of Ice… (it’s true, do the math).
