#IceAge
In a new study our #MPIM_Scientists Thomas Kleinen and Victor Brovkin, together with Sergey Gromov and Benedikt Steil of the Max Planck Institute for Chemistry simulated for the first time the evolution of #climate and methane for the entire period from the last #IceAge to today. In their groundbreaking study, they were able to show that the changes in #methane concentration since the last ice age were caused primarily by tropical wetlands.

Not only is the sculpture just an awesome site but Dick “Sir Mammoth” Mol was a consultant on the project.

Rock on the beach at Barnum Point, Camano Island, WA. Conglomerate with subrounded cherty clasts in a dark matrix. Any sedimentary petrologists? Likely weathered out of till that caps the bluffs or a dropstone from floating ice on marine water incursion during the Everson interstade. Source rock provenance not known. Ref.

More geology from my walk along the bluffs at Barnum Point on Camano Island. Classic glacial sequence in this region displayed in the bluff with advance outwash sand mantled by till from the ice sheet advance of the Vashon stade, i.e. the Puget Lobe. Outwash dated to estimated 18 to 20 ka. Till from about 18 ka to about 13.5 ka. Ref.

At least five times in its history, #Earth froze over, locked in the grip of an #iceage. #Scientists sometimes refer to these periods as “Snowball Earth.” The popular idea is that everything was covered with #ice, making #life difficult, if not impossible. But, there’s new evidence that during at least one of these icy periods, parts of Earth’s surface could have been more like a giant mushy ball of slush.

...there was talk of a "small #IceAge for Northern #Europe, , in particular for the #BritishIsles, which are much warmer due to the #NorthAtlanticCurrent being pushed north by the sinking heavier salt-water in the #AntarcticFront. This can make sense, comparing cities on the same latitude in #Europe and #NorthAmerica: the continental #climate in #Winnipeg is much more extreme, in particular in winter, than in #London (see pic. below)...
Much of Spain/Portugal escaped the last ice-age. Which means most Europeans are probably descended from these Iberian Homo-Sapiens!
"the cave’s inhabitants bequeathed all subsequent Homo sapiens with the memory of their DNA.”

Scientists discover “exquisite“ sabertooth cat skull in Iowa.
The Malalmuerzo cave, located in Moclín, in the Spanish province of Granada, was first inhabited around 30,000 years ago.
Generations of Homo sapiens, all probably descendants of one another, occupied the Malalmuerzo cave for 18,000 years, serving as a refuge for numerous generations of sapiens during the Last Glacial Maximum, which devastated Europe 19,000-25,000 years ago.

The beautifully shaped ice-pushed ridges between Nijmegen (the Netherlands) and Kleve (Germany). You can see the two basins formed by the glacier tongues in the Saale glaciation. The northern edge of the ice pushed ridges is notably eroded by the rivers Rhine and Waal, whereas the southern edge is eroded by the rivers Niers and Meuse. #geology #maps #cartography #iceage #glaciers

It has since been donated to the Science Museum of Minnesota for further study.

"Since the preindustrial times of the mid-1800s, Earth’s #climate has warmed by about 1.2 C (2.2°F). That may seem like a trifling amount until one considers the difference in global temperature today compared to the last #IceAge.
The average global temperature difference between then and now is about 6 C (11°F), or what we can call one “ice age unit.” By that definition, people have already warmed the Earth by 20% of an Ice Age unit."

Children of the Ice Age
"For more than 200 years, children have been neglected by archaeologists. It was part of a disciplinary bias towards adult men in archaeological interpretations. This began to change in the 1970s and ’80s with the rise of feminist archaeology and the archaeology of gender..." cgc373 posted Aeon Magazine's article by April Nowell.

The latest ice age left it's shore laying about in the Swedish mountainous parts. The Swedish term is like "clatterstonefield" directly translated to English. Very hard going here. Due to the pressure of 1km+ of ice, the land is still rising around 0.01m or less per year leaving old shorelines in the woods. Vegetation can't grow, and this is what you may find in or near the lower mountain ridge close to Norway. One tends to avoid them! Boulders as far as you can see.

"...we also need to consider our modern assumptions about children. Why do we imagine them as ‘naive’ figures ‘free of responsibility’? Why do we assume that children couldn’t contribute meaningfully to society?
...A growing body of ethnographic and archaeological research is revealing the ways these forgotten figures have always contributed to the welfare of their communities and themselves."

From Wikipedia: "catastrophic flooding channelled water at 105 km/h through the Upper Grand Coulee and over this 120m rock face at the end of the last glaciation. It is estimated that the falls were five times the width of Niagara Falls, with ten times the flow of all the current rivers in the world combined."

It is fascinating that there are no human finds or evidence of humans in Wales between the time of Paviland and Long Hole Cave until 10000 years later. TEN THOUSAND! An unfathomable amount of time!
Cathole Cave, also on Gower, is a fantastic example.
Stone points were discovered there and dated to around 26000BC, but the art drawn on the rocks dates to 14500BC.
Palaeolithic settlers lived there, then over 11000 years later, people returned!
Today, we leave behind the #Palaeolithic, with its caves, rudimentary stone tools and remains of animals long extinct from #Wales.
The last Ice Age is an important time in Wales. Humans abandoned Wales.
However, this was the time when the land was shaped. Between 27000 and 17000 years ago, most of Wales was covered in ice.
In this 10,000 year span, Eryri (Snowdonia) was carved and Wales's other mountain ranges were shaped!
