2/5 We assessed changes in 3 key biodiversity dimensions (#richness, #composition, and #homogeneity) between ~50K reference communities and 50K human-impacted communities, focusing on major #human #impacts (habitat change, pollution, climate change, resource exploitation, invasive alien species)

Figure 2 from the Nature article 'The global human impact on biodiversity'. It shows the impacts of human pressures on homogeneity and shifts in composition of biological communities globally.

Coastal Environments - LiDAR Mapping of Copper Tailings Impacts, Particle Retention of Copper, Leaching, and Toxicity

maps - Geographic location of Grand (Big) Traverse Bay (red to green contours) along the eastern shoreline of the Keweenaw Peninsula. On the Peninsula, early copper mines are indicated by black dots within the Portage Lake Volcanic Series (dashed lines) and large stamp mills by stars. Two mills (Wolverine and Mohawk) are located near Gay. Insert shows anthropogenic copper inventory “halo” around the Peninsula, in µg/cm² copper

maps - Grand (Big) Traverse Bay: 2010 LiDAR DEM (digital elevation model) colour-coded by elevation and water depth (depth scale to right). Red horizontal contour lines are at 5 m depth intervals. Gay tailings pile (“original pile”) is indicated, as well as migrating underwater stamp sand bars dropping into an ancient river channel (the Trough; at locations #1, and #5). On the eastern flanks of Buffalo Reef, stamp sands are moving out of the Trough into cobble/boulder fields (#3, #4). Along the western edges, stamp sands have migrated as a beach deposit to the Traverse River Seawall (#8) and are slipping down into an underwater depression (#7) next to cobble/boulder fields. Stamp sands are also moving around the harbour outlet (#8). Hence, both the eastern and western sides of Buffalo Reef are experiencing tailings encroachment. Lower on the reef (#2, #6), there is little contamination. Past the Traverse River, the sands in the southern bay are almost exclusively natural quartz grains (#9), forming a white beach with shoreline cusp-like features and bar, plus ridges (#10) of natural sand moving from the shelf into deeper waters off the bay and into Lake Superior

aerial images - UAS high-resolution drone elevation and bathymetry surveys (base map 9 August 2022) of shoreline retreat at the original Gay pile location after bluff removal. Overlays along the beach edge trace shorelines in 2009, 2016, and 2022. The 78 m retreat over 6 years (2016–2022); equates to a 13 m/yr rate. The previous, nearly constant, long-term retreat rate prior to 2009 averaged 7.9 m/yr (ca. 26′) [7,57]. The original Jacobsville Sandstone shoreline, before stamp sands were discharged, is marked by the red border in the far-left upper region. Note white concrete basements of the two mills and remnants of both wooden and broken concrete launders in the northern region. Environmental recovery is beginning, as benthic organisms and fish are returning to clear underwater stretches of the bedrock shelf, where waves have removed stamp sands. Scattered trees (many birch) are beginning to colonise what is left of the original Gay Pile surface.

photos - Gay Stamp Sand Pile. (a) Wooden discharge launder distributing tailings onto the Gay Pile, around 1922, with smaller sluices conveying stamp sand and slime clays laterally (courtesy MTU Archives). (b) Photo of 6–8 m high stamp sand bluffs in July 2008 off Gay, showing a buried small lateral sluiceway protruding out of the pile along the shoreline. Lake Superior waters are to the right; the dark beach sands are stamp sands with intermixed slime clay layers. (c) Bluff photo from about the same location in 2019, when shoreline erosion (ca. 7–8 m/year) reached the buried launder support beams, just before bluff removal.

The Dorrigo Escarpment Great Walk

Intensifying the throughput rate with a series of soaring walkways through the Gondwana Rainforest

The $56.4 million investment in Dorrigo National Park will create “accessible, engaging and immersive experiences for visitors. The 4-day walking track will “connect people with nature... The new 46-km multi-day walk along the rugged escarpment within Dorrigo and Bindarri national parks, includes hiker camps, pedestrian bridges and lookouts.”

The review of environmental factors for the Dorrigo Escarpment Great Walk is available for public comment

Learning interrupted

"Climate shocks are disrupting children’s education, putting their learning and their futures at risk."

"A new UNICEF analysis reveals that at least 242 million students in 85 countries or territories had their schooling disrupted by extreme climate events including heatwaves, tropical cyclones, storms, floods and droughts in 2024, exacerbating an existing learning crisis."

Le premier épisode est en ligne !

Petite histoire de l'#IA
À écouter sur https://lafourmi.media/

Tentons d’apporter une #définition de l’intelligence artificielle à travers son #histoire, croisée avec l’histoire de la philosophie, de la logique et de l’informatique. Nous pourrons alors mieux comprendre ce que le terme I.A. recouvre et les concepts associés, pour mieux savoir en évaluer les #impacts et avoir les outils pour en parler.

Lundi 13 janvier 2025, nous vous proposons de découvrir le nouveau numéro de @curseurs sur le thème de la #matérialité du #numérique.

En rupture avec l'imaginaire dématérialisé souvent associé à ces technologies, ce numéro invite à explorer l'infrastructure technique de câbles et de machines qui leur permettent de fonctionner. Au-delà d'enjeux proprement techniques, il invite aussi à prendre la mesure des #impacts sociaux et environnementaux que ces technologies engendrent.

Illustration en noir et blanc utilisée pour la couverture du numéro 4 de Curseurs. S'y mêlent des éléments sous sous-marins naturels (poissons, méduses, coraux, etc.) avec des éléments artificiels (câbles sous-marins, câbles réseau, valves, outillage et machines de construction, etc.). L’illustration superpose une vue sous-marine et celle d’un chantier de construction d’un grand bâtiment moderne qui pourrait devenir un centre de données.
