Petrostates planning huge expansion of fossil fuels, says UN report – “These plans throw humanity’s future into question. Governments must stop saying one thing and doing another.”

By Damian Carrington 8 November 2023 (The Guardian) – The world’s fossil fuel producers are planning expansions that would blow the planet’s carbon budget twice over, a UN report has found. Experts called the plans “insanity” which “throw humanity’s future into question”. The energy plans of the petrostates contradicted their climate policies and pledges, the report said. […]

Why are Alaska’s rivers turning orange? “It was a famous, pristine river ecosystem, and it feels like it’s completely collapsing now”

By Alec Luhn 24 December 2023 (Scientific American) – It was a cloudy July afternoon in Alaska’s Kobuk Valley National Park, part of the biggest stretch of protected wilderness in the U.S. We were 95 kilometers (60 miles) from the nearest village and 400 kilometers from the road system. Nature doesn’t get any more unspoiled. […]

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. It was plastic, sure. But what kind? There was no resin code or recycling symbol on the package. Nothing on […]

Why carbon capture is no easy solution to climate change – “Not all technologies are going to be possible in all locations”

By Leah Douglas 27 November 2023 (Reuters) – Technologies that capture carbon dioxide emissions to keep them from the atmosphere are central to the climate strategies of many world governments as they seek to follow through on international commitments to decarbonize by mid-century. But they are also expensive, unproven at scale, and can be hard […]

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

Climate change emerges as major driver of amphibian declines, new research finds – “It’s a gut punch and an awakening”

By JoAnn Adkins 4 October 2023 (FIU) – Amphibians are in trouble and in desperate need of conservation action, according to a new global assessment of the world’s amphibian population. Salamanders are experiencing the greatest decline in numbers, but frogs, toads, newts, and salamanders throughout the Neotropics — extending from South Florida and Caribbean islands […]

Forests are no longer our climate friends – “As extreme as this year’s wildfire emissions have been, they are just the latest escalation in a multi-decade flood of CO₂ pouring out of Canada’s ‘managed’ forests and forestry”

By David Wallace-Wells 6 September 2023 (The New York Times) – Canadian wildfires have this year burned a land area larger than 104 of the world’s 195 countries. The carbon dioxide released by them so far is estimated to be nearly 1.5 billion tons — more than twice as much as Canada releases through transportation, […]

Wildfires in Canada’s Northwest Territories have released 97 megatons of carbon, 277 times what its people emit – Emissions from wildfires across Canada in 2023 vastly exceed the 2014 record

By Liny Lamberink 28 August 2023 (CBC News) – Wildfires in the N.W.T have emitted 97 megatonnes of carbon into the air so far this year — 277 times more than what was caused by humans in the territory back in 2021.
