Biomass and anthropogenic mass estimates since the beginning of the twentieth century on a dry-mass basis. The green line shows the total weight of thebiomass (dashed green lines, ±1 s.d.). Anthropogenic mass weight is plotted as an area chart, where the heights of the coloured areas represent the mass of the corresponding category accumulated until that year. The anthropogenic mass presented here is grouped into six major categories. The year 2020±6 marks the time at which biomass is exceeded by anthropogenic mass. Anthropogenic mass data since 1900 were obtained from ref. 22, at a single-year resolution. The current biomass value is based on ref. 11, which for plants relies on the estimate of ref. 10, which updates earlier, mostly higher estimates. The uncertainty of the year of intersection was derived using a Monte Carlo simulation, with 10,000 repeats. Data were extrapolated for the years 2015–2025 (lighter area).

The mass of human-made materials now equals the planet’s biomass – “Anthropogenic” mass is doubling every twenty years

9 December 2020 (Weizmann Institute of Science) – Earth circa 2020: The mass of all human-produced materials – concrete, steel, asphalt, etc. – has grown to equal the mass of all life on the planet, its biomass. According to a new study at the Weizmann Institute of Science, we are right at this tipping point, […]

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 […]

U.S. job market slowed further in November 2020 – “We’re going to have a few of the toughest months of this pandemic, and there will be a lot of scars left to heal”

6 December 2020 (The New York Times) – The American economic recovery continues to slow, stranding millions who have yet to find a new job after being thrown out of work by the coronavirus pandemic. The latest evidence came Friday when the Labor Department reported that employers added 245,000 jobs in November, the fifth month in a […]

Carbon dioxide levels continue at record levels, despite COVID-19 lockdown – “The COVID-19 pandemic is not a solution for climate change”

GENEVA, 23 November 2020 (WMO) – The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of greenhouse gases which are trapping heat in the atmosphere, increasing temperatures, and driving more extreme weather, ice melt, sea-level rise, and ocean acidification, according to the World Meteorological Organization (WMO). The lockdown has cut emissions […]

U.N. warns 2021 shaping up to be a humanitarian catastrophe – “The worst humanitarian crisis year since the beginning of the United Nations 75 years ago”

By Michelle Nichols 4 December 2020 NEW YORK (Reuters) – Next year is shaping up to be a humanitarian catastrophe and rich countries must not trample poor countries in a “stampede for vaccines” to combat the coronavirus pandemic, top U.N. officials told the 193-member U.N. General Assembly on Friday. World Food Programme (WFP) chief David […]

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.

Tire dust killing coho salmon returning to Puget Sound, new research shows – “I find it incredibly sad to watch the adults when they are sick”

By Lynda V. Mapes 3 December 2020 (Seattle Times) – First they circle. Then they gasp at the surface of the water. Soon they can’t swim. Then they die. For decades now, scientists have known something was killing beautiful, adult coho salmon as soon as they hit Seattle’s urban waters, ready to spawn. They had […]
