Traces of sunscreen agents in the snow at the North Pole – “Many of the contaminants we have analysed had never been identified in Arctic snow before”

20 December 2023 (Ca’ Foscari University of Venice) – Traces of sunscreen agents were found at the North Pole, on the glaciers of the Svalbard archipelago. They were mainly deposited in winter, when night falls over the Arctic. A study conducted by researchers from Ca’ Foscari University of Venice and the Institute of Polar Sciences – National […]

U.S. landfill tonnages by waste type, 1960-2018. In 2018, about 146.1 million tons of municipal solid waste (MSW) were landfilled. Food was the largest component at about 24 percent. Plastics accounted for more than 18 percent, paper and paperboard made up about 12 percent, and rubber, leather and textiles comprised over 11 percent. Other materials accounted for less than 10 percent each. Graphic: EPA

I’m appalled by what I learned about recycling. But we can fix it.

By Oliver Franklin-Wallis 29 November 2023 (The New York Times) – It happened again the other night: Washing up after dinner, I went to throw out a packet of just-eaten instant tortellini and was flummoxed.

Heat, drought, floods, bad air: Will California’s Central Valley survive climate change? “It’s almost like the forecast for the middle, late century – we’re seeing it right now”

By Hayley Smith 25 October 2023 (Los Angeles Times) – One March morning in the small Central Valley town of Woodlake, Joshua Diaz was getting out of bed when he noticed that his carpet was bubbling and that his tile floor had grown slick. He tried to open his front door but felt pressure and […]

Geographical pattern of the primary drivers of deteriorating status among amphibians. a,b, The primary drivers of deteriorating status among amphibians during 1980–2004 (482 species; a) and 2004–2022 (306 species; b). Cell colour was determined by the primary driver impacting the most species. Where two primary drivers equally contribute to a cell, an intermediate colour is shown. The stars indicate where the primary driver is undetermined or there are numerous primary drivers. The cell area is 7,775 km2. Graphic: Luedtke, et al., 2023 / Nature

The atomic bomb laid down the marker for humanity’s era of catastrophic change – “An observable, unambiguous change in the physical properties or fossil content of the strata”

By Stephen Trimble 3 September 2023 (Los Angeles Times) – Christopher Nolan believes J. Robert Oppenheimer is the most important person who ever lived. “By unleashing nuclear power,” the film director concludes, “he gave us the power to destroy ourselves.” Nolan might exaggerate, but Oppenheimer, the subject of Nolan’s hit movie, is surely worthy of the […]

Correlation of significant shifts in or appearances of markers between sites documenting the onset of the Anthropocene. Collectively, the 12 reference sites, via analysis across many sites using similar multiple proxies, show the extent to which the proxies at each site cluster at an approximately coincident level around the mid-20th century, consistent with the Great Acceleration Event Array (GAEA) proposed by Waters et al. (2022). This demonstrates the degree to which the primary marker chosen at a site represents the range of critical changes encompassed by that section. Each site team has identified a level where significant changes cluster, these ranging in age between 1945 and 1968 CE, though for most sites the level chosen dates to the 1950s.
