WWF: Looming mass extinction could be biggest since the dinosaurs – “One million species could go extinct within the next decade, which would be the largest mass extinction event since the end of the dinosaur age”

29 December 2021 (DW) – Ever-growing environmental threats are pushing many animals and plants to the brink of extinction — the scale of which hasn’t been seen since dinosaurs died out, the German branch of the World Wildlife Fund (WWF) said on Wednesday. The stark warnings came as WWF Germany released its “Winners and Losers of 2021,” an annual […]

Hunger, drought, disease: UN climate report reveals dire health threats – “The basis for our health is sustained by three pillars: the food we eat, access to water, and shelter. These pillars are totally vulnerable and about to collapse.”

By Patrick Galey 23 June 2021 (AFP) – Hunger, drought and disease will afflict tens of millions more people within decades, according to a draft UN assessment that lays bare the dire human health consequences of a warming planet. After a pandemic year that saw the world turned on its head, a forthcoming report by […]

The American West is drying out – Lake Mead, largest reservoir in U.S., drops to lowest level on record since it was filled in the 1930s

By Zachary B. Wolf 20 June 2021 (CNN) – The incredible pictures of a depleted Lake Mead, on the Nevada-Arizona border, illustrate the effects of drought brought on by climate change. Later this year, the US government will almost certainly declare the first-ever water shortage along the Colorado River. Maps show more than a quarter of the US […]

Drought saps California reservoirs as hot, dry summer looms – “It makes me feel like our planet is literally drying up,”

By Adam Beam 17 June 2021 OROVILLE, Califorina (AP) – Each year Lake Oroville helps water a quarter of the nation’s crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires. But the mighty lake — a […]

Lake Washington sockeye salmon hit record low – “In a generation, we have gone from times of plenty to these fish being on the brink of extinction”

By Lynda V. Mapes 1 January 2021 (The Seattle Times) – They are as Seattle as the Space Needle. But Lake Washington sockeye, once the largest run of sockeye in the Lower 48, are failing. The smallest run on record returned to the Cedar River in 2020, a bottoming out after years of declines. There […]

Climate change now top threat to natural World Heritage sites – Great Barrier Reef declines to “critical” status

GLAND, SWITZERLAND, 2 December 2020 (IUCN) – Climate change is now the biggest threat to natural World Heritage, according to a report [pdf] published today by IUCN (International Union for Conservation of Nature). A third (33%) of natural World Heritage sites are threatened by climate change, including the world’s largest coral reef, the Great Barrier […]

Environmental relevance of 6PPD-quinone. (A) Using retrospective UPLC-HRMS analysis of archived sample extracts, 6PPD-quinone was quantified in roadway runoff and runoff-impacted receiving waters. Each symbol corresponds to duplicate or triplicate samples, boxes represent first and third quartiles. For comparison, the 0.8 pg/L LC50 value for juvenile coho salmon and detected 6PPD-quinone levels in 250 and 1000 mg/L TWP leachate are included. (B) Predicted ranges of potential 6PPD-quinone mass formation in passenger cars (e.g., 4 tires, -36 kg tire rubber mass) and heavy trucks, (e.g., 18 tires, -900 kg of tire rubber) (represented in orange) and measured 6PPD-quinone concentrations in affected environmental compartments (represented in blue, with experimental data italicized). Predicted ranges reflect calculations applying 0.4-2% 6PPD per total vehicle tire rubber mass followed by various yield scenarios (1-75% ultimate yields) for 6PPD reaction with ground-level ozone to form 6PPD-quinone.
