BREAKING: Another extinct ice age beast exhumed from the permafrost. Exceptionally well-preserved carcass of a juvenile woolly rhinoceros discovered in Yakutia. Its internal organs and stomach contents await investigation. Photos by Valery Plotnikov. siberiantimes.com/other/others/n…
“The juvenile rhino with thick hazel-coloured hair and the horn, found next to the carcass, was discovered in the middle of August in permafrost deposits by river Tirekhtyakh in the Abyisky ulus (district) of the Republic of Sakha.”
“It is the best preserved to date juvenile woolly rhino ever found in Yakutia, with a lot of its internal organs - including its teeth, part of the intestines, a lump of fat and tissues - kept intact for thousands of years in permafrost.” #IceAgeExtinction
Temperatures in the Siberian Arctic in the summer of 2020 were the highest on record leading to sustained thawing of the permafrost bbc.com/news/science-e…
Warming is contributing to these discoveries but it’s not exclusively a product of climate warming. Well-equipped gangs seeking woolly mammoth tusks are exhuming long-buried ice age carcasses as they blast the Pleistocene mud with water jets wired.co.uk/article/mammot…
More photos of the ice age woolly rhino recovered from the Siberian permafrost. Radiocarbon dating and DNA analysis will be key aspects of the laboratory work theguardian.com/science/2020/d…

Cold comfort: what can Arctic cultures teach us for our future survival? theguardian.com/artanddesign/2…
“A circular map with the North Pole at its centre details 24 different cultural groups wheeling around the Arctic circle; some 400,000 people.”
“No other human cultures experience such seasonality, such extremes of midsummer light and midwinter dark. No other cultures use ice in so many ways: for transport, building material, food preservation.”

A century or so ago, Serbian scientist Milutin Milankovitch hypothesised the long-term effects of changes in Earth’s position relative to the Sun are responsible for driving shifts in ice age climate climate.nasa.gov/news/2948/mila…
“Specifically, he examined how variations in three types of Earth orbital movements affect how much solar radiation (known as insolation) reaches the top of Earth’s atmosphere as well as where the insolation reaches.”
“These cyclical orbital movements, which became known as the Milankovitch cycles, cause variations of up to 25 percent in the amount of incoming insolation at Earth’s mid-latitudes.”

“Our fear of wolves is out of all proportion to the danger they pose us.” Why landscapes need the wolf... theguardian.com/environment/20…
“If the trajectory of the European wolf is dispiriting, it is also familiar. We have become well acquainted with graphs that plot the advance of humans against the decline of all else.”
“But over the last century, a different narrative has been writing itself into existence. In Europe, patterns of farming and land use have been changing on a grand scale, as marginal land – too steep or too depleted to be worth the effort of farming – falls into disuse.”

Plant fossils reveal that atmospheric CO2 concentrations have not been this high for at least 23 million years and have never risen so rapidly newatlas.com/environment/co…
“Lately we’ve been breaking a lot of records in terms of atmospheric carbon dioxide levels. In 2016 the South Pole became the last region on Earth to exceed a concentration of 400 parts per million (ppm).”
“In May 2019, the Mauna Loa Observatory in Hawaii picked up a record new high of 415.26 ppm. Currently, levels are the highest they've been in all of human history.”

WOW! Mass grave of at least 22 ice age giant ground sloths discovered on southwest coast of Ecuador gizmodo.com/mass-grave-of-…
“Many of the bones were disarticulated and had the type of gouges to suggest trampling by other creatures after they had died. Something catastrophic caused 22 giant ground sloths—many the size of modern elephants—to perish at the same time and in the same place”
“Fifteen of the giant ground sloths were adults; the rest were subadults and juveniles, a couple of them so tiny that they might have been newborns or even fetuses.”

From the archive: #EarthDay2020

This time last year I saw the longest tusks in the world in the wonderful museum at Malia in northern Greece. These belonged to the remarkable Pliocene beast Mammut borsini 🇬🇷
The longest tusk is 5.02 m long and was excavated in July 2007. It is the second from right in this photo. This beat the previous record of 4.39 m excavated in 1997 (far left) #EarthDay2020
Here’s the excellent palaeoart of Mammut borsoni by Remie Bakker. His work appears in various displays at the Natural History Museum in Malia. This was not an ice age beast. The Pliocene was warmer and this animal was a forest dweller 🌳🌳
