“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.”
“This map makes us rethink our customary projections that locate Arctic cultures as the upper remotes of European or North American or Russian states.”
“To Arctic peoples themselves the distances are shorter, they know their neighbours. Trade and influence around Arctic groups has been going on for millennia.”

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.”
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 🌳🌳
“The underground homes, often a century old, are topped with gardens exploding with lush dune grass, diamondleaf willows, and yellow wildflowers—a flash of color in an otherwise gray landscape.” ❄️🦊
“During the long, dark Arctic winter, the tundra fades into an opaque world where sky and ground blend into a never-ending haze.”
