Black carbon mass density over North America from GEOS-5, 21 July 2021. Smoke from wildfires in the U.S. West poured into the eastern U.S. on 20-21 July 2021. In New York City, levels of fine particulate pollution rose above 170 on the air quality index, a level considered harmful even for healthy people.

Skies turn hazy from Pittsburgh to Washington to Boston, as smoke from fires in Canada pour into the U.S. Northeast

By Adam Voiland 23 July 2021 (NASA) – While plumes of wildfire smoke from western North America have passed over the northeastern U.S. and Canada multiple times each summer in recent years, they often go unnoticed. That is because smoke that spreads far from its source typically moves at a fairly high altitude—between 5 and 10 kilometers—as […]

Great Salt Lake is shrinking fast – Scientists demand action before it becomes a toxic dustbin – “We’re on the doorstep of a catastrophe”

By Lucy Kafanov, Leslie Perrot, and Eliott C. McLaughlin 17 July 2021 Great Salt Lake, Utah (CNN) – Great Salt Lake is also known as America’s Dead Sea — owing to a likeness to its much smaller Middle Eastern counterpart — but scientists worry the moniker could soon take new meaning. Human water consumption and […]

Total greenhouse gas emissions from China and OECD nations, 1990-2019. In 2019, China’s GHG emissions passed the 14 gigaton threshold for the first time, reaching 14,093 million metric tons of CO2 equivalent (MMt CO2e). This represents a more than tripling of 1990 levels, and a 25 percent increase over the past decade. As a result, China’s share of the 2019 global emissions total of 52 gigatons rose to 27 percent.

China’s greenhouse gas emissions exceeded the developed world for the first time in 2019

By Kate Larsen, Hannah Pitt, Mikhail Grant, and Trevor Houser 6 May 2021 (Rhodium Group) – Each year Rhodium Group provides the most up-to-date global and country-level greenhouse gas (GHG) emissions estimates through the ClimateDeck (a partnership with Breakthrough Energy). In addition to our preliminary US and China GHG estimates for 2020, Rhodium provides annual estimates of economy-wide emissions—including all […]

Annual Greenhouse Gas Index (AGGI), 1750-2020. For 2020, the AGGI was a record high 1.47, representing an increase in total direct radiative forcing of 47 percent since 1990. This increase in CO2 is accelerating — while it averaged about 1.6 ppm per year in the 1980s and 1.5 ppm per year in the 1990s, the growth rate increased to 2.4 ppm per year during the last decade (2009-2020). Pre-1978 changes in the CO2-equivalent abundance and AGGI based on the ongoing measurements of all greenhouse gases reported here, measurements of CO2 going back to the 1950s from C.D. Keeling [Keeling et al., 1958], and atmospheric changes derived from air trapped in ice and snow above glaciers [Machida et al., 1995, Battle et al., 1996, Etheridge, et al., 1996; Butler, et al., 1999]. Equivalent CO2 atmospheric amounts (in ppm) are derived with the relationship between CO2 concentrations and radiative forcing from all long-lived greenhouse gases.

Another record high for NOAA Annual Greenhouse Gas Index in 2020 – CO2 increase continues accelerating – No slowdown from Covid pandemic seen

26 May 2021 (NOAA) – […] The atmospheric abundance of CO2 has increased by an average of 1.85 ppm per year over the past 41 years (1979-2020). This increase in CO2 is accelerating — while it averaged about 1.6 ppm per year in the 1980s and 1.5 ppm per year in the 1990s, the growth rate increased to […]

“Imminent” collapse of wastewater reservoir in Florida forces evacuations – 20-foot “wall of water” if reservoir breaches – Workers try to prevent “real catastrophic flood situation”

By Raja Razek and Alaa Elassar 4 April 2021 (CNN) – Response teams in Manatee County Florida are trying to prevent a “real catastrophic flood situation” in the Piney Point reservoir area, Gov. Ron DeSantis said Sunday after taking an aerial tour the area. The governor assured the public that the water being discharged to […]

Scientist tells of relief after speaking out over weedkiller fears – Herbicide poisoning expert says paraquat responsible for “tens of thousands” of deaths worldwide

By Ben Quinn 24 March 2021 (The Guardian) – A scientist with one of the world’s largest chemical firms took the difficult decision to speak out publicly when “a new generation” of managers rejected concerns about a mass-produced weedkiller that he had been expressing for decades. Going public has been a “relief”, says toxicologist Jon […]

Illegal gold rush in the Amazon raises risk to indigenous people – “They are coming in like starved beasts, looking for the wealth of our land”

By Luana Souza 24 March 2021 (Bloomberg News) – Illegal gold and diamond mining is proliferating in Brazil’s Amazon rain forest and threatening South America’s largest group of native people who still live in relative isolation, the Yanomami. Criminal mining groups are encroaching on the indigenous territory that straddles Brazil and Venezuela, polluting rivers, bringing diseases […]

Ten years on, Japan mourns victims of earthquake and “profoundly man-made” Fukushima disaster

By Eimi Yamamitsu 10 March 2021 IWAKI, Japan (Reuters) – With a moment of silence, prayers, and anti-nuclear protests, Japan on Thursday mourned about 20,000 victims of the massive earthquake and tsunami that struck Japan 10 years ago, destroying towns and triggering nuclear meltdowns in Fukushima. Huge waves triggered by the 9.0-magnitude quake – one […]
