Number of generic extinctions per century among in different classes of vertebrates. The low number of reptiles and amphibia, which underestimate the magnitude of extinction pattern, is probably the result of the lack of information in earlier centuries, where very few species had been described.

Study finds human-driven mass extinction is eliminating entire branches of the tree of life – “We’re losing our only known living companions in the entire universe”

By Sean Cummings 18 September 2023 (Stanford News) – The passenger pigeon. The Tasmanian tiger. The Baiji, or Yangtze River dolphin. These rank among the best-known recent victims of what many scientists have declared the sixth mass extinction, as human actions are wiping out vertebrate animal species hundreds of times faster than they would otherwise […]

Carbon credit market confidence ebbs as big names retreat – Voluntary carbon markets shrink in 2023 for the first time in at least seven years

By Susanna Twidale and Sarah Mcfarlane 1 September 2023 LONDON (Reuters) – Voluntary carbon markets have shrunk for the first time in at least seven years, as companies including food giant Nestlé and fashion house Gucci reduced buying and studies found several forest protection projects did not deliver promised emissions savings. Preserving forests is crucial […]

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, […]

Hunger, food insecurity still higher than before pandemic – At the global level, there was no progress toward reducing food insecurity in 2022

30 August 2023 (Gallup) – Although hunger at the global level stopped rising in 2022, the latest State of Food Security and Nutrition in the World (SOFI) report shows that it is still increasing in many places around the world and that levels of both hunger and food insecurity remain higher today than they were before the pandemic.

Humans are releasing greenhouse gases at level unprecedented in geologic history – “Uncertainty is not our friend”

By Saul Elbein 7 September 2023 (The Hill) – Human civilization came to be thanks to the comparatively stable climate of the past 10,000 years. But the unchecked burning of fossil fuels is undermining that foundation, according to a leading climate scientist. “There is no analog in the past for the rapid warming” we are […]

Home insurers cut natural disasters from policies as climate risks grow – “The same risks that are making insurance more important are making it harder to get”

By Jacob Bogage 3 September 2023 (The Washington Post) – In the aftermath of extreme weather events, major insurers are increasingly no longer offering coverage that homeowners in areas vulnerable to those disasters need most. At least five large U.S. property insurers — including Allstate, American Family, Nationwide, Erie Insurance Group and Berkshire Hathaway — […]

“We’re going to sink”: hundreds abandon Caribbean island home – “Almost all the islands are going to be abandoned by the end of this century”

By Juan José Rodríguez 6 September 2023 (AFP) – On a tiny Caribbean island, hundreds of people are preparing to pack up and move to escape the rising waters threatening to engulf their already precarious homes. Surrounded by idyllic clear waters, the densely populated island of Carti Sugtupu off Panama’s north coast has barely an […]

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. Mark Parrington, a senior scientist working at the European Union’s Copernicus Atmosphere Monitoring Service (CAMS), […]

Thousands of scientists are cutting back on Twitter, seeding angst and uncertainty – “Now it’s just a cesspool of trolls and bots”

By Michael Hiltzik 25 August 2023 (Los Angeles Times) – In the first couple of years of the COVID-19 pandemic, Peter Hotez, an expert in vaccines and tropical medicine at Baylor University, found Twitter to be “a useful and at times almost essential tool for timely and important exchange of information.” The platform banned the […]

ExxonMobil predicts climate efforts will fail – “Fossil fuels remain the most effective way to produce the massive amounts of energy needed to create and support the manufacturing, commercial transportation, and industrial sectors that drive modern economies”

By Maggie Harrison 1 September 2023 (Futurism) – According to Exxon Mobil, oil giant and one of the more prominent architects of our planet’s fossil fuel-laden doom, humanity is likely to fail its climate goals of halting a global temperature rise of two degrees Celsius by 2050. As The Wall Street Journal reports, Exxon published its grim prediction in […]
