Imagine that. We should figure out where/how the European stupid gene developed ... |

Is GDS really a far fetched idea? The Role of Geomagnetic Field Intensity in Late Quaternary Evolution of Humans and Large Mammals
The demise of Neanderthals at ~41 ka can now be closely tied to the intensity minimum associated with the Laschamp magnetic excursion, and the survival of anatomically modern humans can be attributed to differences in the aryl hydrocarbon receptor that has a key role in the evolutionary response to UVR flux. Fossil occurrences and dung‐fungal proxies in Australia indicate that episodes of Late Quaternary extinction of mammalian megafauna occurred close to the Laschamp and Blake magnetic excursions. Fossil and dung fungal evidence for the age of the Late Quaternary extinction in North America (and Europe) coincide with a prominent decline in geomagnetic field intensity at ~13 ka. Over the last ~200 kyr, phylogeny based on mitochondrial DNA and Y chromosomes in modern humans yields nodes and bifurcations in evolution corresponding to geomagnetic intensity minima, which supports the proposition that UVR reaching Earth's surface influenced mammalian evolution with the loci of extinction controlled by the geometry of stratospheric ozone depletion.agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018RG000629magneticreversal.org/Yes it is interesting. I just read the paper  . It also challenges the meme that early humans were responsible for hunting large fauna to extinction. If a cure for cancer is identified we may break the link to geomagnetic minima for humans. But wait there's more... "New evidence suggests a huge asteroid DID hit EARTH 12,800 years ago causing an ice age, wiping out dozens of species and decimating humans
A team of scientists discovered a 'platinum spike' suggesting a meteorite had hit
Found in Wonderkrater in the Limpopo Province, north of Pretoria in South Africa
Findings could prove mini-ice age Younger Dryas was triggered by a meteoroid
A huge asteroid may have hit the Earth 12,800 years ago causing global climate change and extinction, according to new evidence found in South Africa.
Scientists analysed ancient soil at a site called Wonderkrater and found high levels of platinum - which they say supports the The Younger Dryas Impact Hypothesis that a disintegrating meteor hit Earth and caused a mini ice age.
The resulting ice age is believed by many scientists to have wiped out dozens of mammals species including the Mammoth and giant wildebeest and decimated the human population.
Scientists believe 'platinum spikes' found in ancient soil samples across the world are evidence of the meteor fragments that crashed into Earth.

Abstract:
Wonderkrater in the Limpopo Province in South Africa is a late Quaternary archaeological site with peat deposits extending back more than 30 000 years before the present. Palaeoclimatic indices based on multivariate analysis of pollen spectra reflect a decline in temperature identifiable with the Younger Dryas (YD). A prominent spike in platinum is documented in aWonderkrater sample (5614) with a mean date of 12 744 cal yr BP using a Bayesian model, preceding the onset of the YD cooling event. The YD platinum spike at Wonderkrater is the first to be observed in Africa in the southern hemisphere, supplementing new discoveries from Patagonia in South America, in addition to more than 25 sites with such platinum anomalies in the northern hemisphere. The observations from South Africa serve to strengthen ongoing assessments of the controversial YD Impact Hypothesis, whereby it is proposed that a meteorite or cometary impact contributed to a decline in temperature, associated inter alia with dispersion of atmospheric dust, mammalian extinctions and cultural changes."wiredspace.wits.ac.za/handle/10539/28129 |

And the Maya were capable of producing enough CO2 to cause worldwide climate change....  "Ancient Maya Canals and Fields Show Early and Extensive Impacts on Tropical Forests
USTIN, Texas — New evidence in Belize shows the ancient Maya responded to population and environmental pressures by creating massive agricultural features in wetlands, potentially increasing atmospheric CO2 and methane through burn events and farming, according to geographical research at The University of Texas at Austin published in the Proceedings of the National Academy of Sciences.
Prior research proposed that the Maya’s advanced urban and rural infrastructure altered ecosystems within globally important tropical forests. But in the first study to combine airborne lidar (light detection and ranging) imagery with excavation and dating evidence in wetlands, researchers found the Birds of Paradise wetland field complex to be five times larger than previously discovered and found another, even larger, wetland field complex in Belize.
Altogether, the study shows the Maya had “earlier, more intensive and more wide-ranging anthropogenic impacts” on globally important tropical forests than previously known, adding to the evidence for an early and more extensive Anthropocene — the period when human activity began to greatly affect Earth’s environment.
“We now are beginning to understand the full human imprint of the Anthropocene in tropical forests,” said Tim Beach, the study’s lead author, who holds the C.B. Smith, Sr. Centennial Chair. “These large and complex wetland networks may have changed climate long before industrialization, and these may be the answer to the long-standing question of how a great rainforest civilization fed itself.”"news.utexas.edu/2019/10/07/ancient-maya-canals-and-fields-show-early-and-extensive-impacts-on-tropical-forests/How stupid are these people who hold the C B Smith sr Centennial Chair? Perhaps if he was not holding furniture and had a better grasp of how HUGE the climate system is compared to what the Maya were doing he might have a better understanding. |

There ought to be a mechanism for retracting Ph.Ds. Perhaps he could then better relate to the Mayan end game. |

Interesting particularly toward the end ...
So about the Earth's precession axial tilt and magnetic field ....

Croatia is unseasonably warm atm, locals still swimming in the sea, something they really do not do unless its very warm.
This late in the year, this is very unusual behaviour!
Meanwhile, UK has had its first below average monthly CET for 18 months....
Above average rainfall too, a little further north then me, they're struggling to get into fields to do autumn seeding.

A lot of Oz is relative cool, atm. Some heat arriving towards the end of next week in a few places. Yawn .... MetEye |

Here in Middle Earth October mean temperature anomaly was -2.4 F. It would have been -5 F if the 2 first days of the month hadn't been +20 F before the chill set in. Precip. 100% above normal. We are NOT swimming. |
