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 […]

Brazil’s big cats under threat from wind farms – “Wind power is a fantastic proposal, and the northeast certainly has plenty of wind … but wind parks must also take into account what is happening here on the ground”

By Luciana Magalhaes and Samantha Pearson 17 September 2023 JUAZEIRO, Brazil – Weighing more than 100 pounds, big cats have long reigned over this hot and semi-arid region of Brazil, developing tougher paws for the scorched earth and reaching speeds of 50 miles an hour to bring down wild boar and deer. But nothing could […]

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, […]

Some Florida Keys corals are losing their color weeks earlier in the summer than has been documented before, meaning they are under stress and their health is potentially endangered, federal scientists said.

Florida’s record hot ocean temperatures cause early coral bleaching – Some reefs in the Florida Keys have already lost all their color – “We are at least a month ahead of time, if not two months”

By Cecelia Smith-Schoenwalder 26 July 2023 (US News & World Report) – Record high ocean temperatures around the Florida Keys are driving coral reefs to lose their color weeks earlier than usual in the latest sign that climate change and El Niño are pushing the world into uncharted territory. On Monday, a buoy in the […]

Ghost forests: coastal forests dying off as sea-level rise accelerates

By Ginger Zee, Daniel Manzo, and Kelly Livingston 6 July 2023 (ABC News) – As people around the world contend this week with the hottest temperatures ever recorded on Earth, more visual evidence of climate change is emerging with the spread of ghost forests. The globe is naturally warming and seas naturally rise, but greenhouse […]

Construction site of the Gemini solar project in southern Nevada. Documents obtained under the Freedom of Information Act by the conservation group Defenders of Wildlife show the bureau’s Las Vegas field office drafted several versions of a “record of decision” that would have denied the permit application for Gemini. The drafts listed several objections, including harm to desert tortoises, loss of space for off-road vehicle drivers and disturbance of the Old Spanish National Historic Trail, which runs through the project site.

Solar sprawl is tearing up the Mojave Desert. Is there a better way?

By Sammy Roth 27 June 2023 (Los Angeles Times) – High above the Las Vegas Strip, solar panels blanketed the roof of Mandalay Bay Convention Center — 26,000 of them, rippling across an area larger than 20 football fields. From this vantage point, the sun-dappled Mandalay Bay and Delano hotels dominated the horizon, emerging like […]

Seasonal managed honeybee colony loss rates in the United States across years 2008-2023 (A), and by operation type (B-D): backyard (managing up to 50 colonies), sideline (managing 51-500), and commercial (managing >500 colonies) beekeepers. The loss rate was calculated as the total number of colonies lost divided by the number of colonies at risk during the season. Colonies at risk were composed of living colonies at the start of a period, as well as new colonies made or acquired, while excluding colonies sold or parted with. Annual loss covers the whole period from one 1 April to the next 1 April (in red); summer (1 April – 1 October, in yellow); winter (1 October – 1 April, in blue). Error bars represent the 95% confidence interval obtained from a bootstrap resampling of the data (n-out-of-n, 1000 rep). Graphic: Bee Informed Partnership

Nearly half of U.S. honeybee colonies died in the 2022-2023 season – “This is a very troubling loss number when we barely manage sufficient colonies to meet pollination demands in the U.S.”

By Seth Borenstein 22 June 2023 WASHINGTON (AP) – America’s honeybee hives just staggered through the second highest death rate on record, with beekeepers losing nearly half of their managed colonies, an annual bee survey found. But using costly and Herculean measures to create new colonies, beekeepers are somehow keeping afloat. Thursday’s University of Maryland […]

The human Ecological Footprint measured as “Overshoot Day”, 1971-2023. The Ecological Footprint is the most comprehensive biological resource accounting metric available. Based on 15,000 data points per country per year, it adds up all of people’s competing demands for biologically productive areas – food, timber, fibers, carbon sequestration, and accommodation of infrastructure. Currently, the carbon footprint, i.e., the carbon emissions from burning fossil fuel, make up 61 percent of humanity’s Ecological Footprint. For the last 5 years, the trend has flattened. How much of this is driven by economic slow-down or deliberate decarbonization efforts is difficult to discern. Still, overshoot reduction is far too slow. To reach the UN’s IPCC target of reducing carbon emissions by 43 percent worldwide by 2030 compared to 2010 would require moving Earth Overshoot Day 19 days annually for the next seven years.

The 2023 Earth Overshoot Day lands on August 2 – Trend is flattening but still far from reversing – “Persistent overshoot leads to ever more prominent symptoms including unusual heat waves, forest fires, droughts, and floods, with the risk of compromising food production”

GENEVA, SWITZERLAND, 5 June 2023 – August 2nd marks this year’s Earth Overshoot Day, according to the latest National Footprint and Biocapacity Accounts. They now track countries’ performance up to 2022, reducing reporting lag by three years. However, Earth Overshoot Day’s apparent delay by five days compared to last year’s isn’t all good news, as genuine advancements amount […]

One year after they were murdered, their work must go on – Forest defender Bruno Araújo Pereira and journalist Dom Phillips were assassinated in Brazil on 5 June 2022

By Katharine Viner 1 June 2023 (The Guardian) – Forest defenders should not be killed for exposing crimes. Journalists should not be killed for reporting facts. But, one year ago, the Guardian was devastated by the awful news that in the Amazon rainforest, two lives had been taken on the frontline of the battle to protect the […]

Map showing the number of subglobal climate (two local exposure boundaries), functional integrity, surface water, groundwater, nitrogen, phosphorus and aerosol safe and just Earth system boundaries (ESBs) currently transgressed by location. No more than seven of these eight metrics have their ESBs transgressed in any one pixel. Since climate is a globally defined ESB, we use wet bulb temperatures of over 35°C for at least 1-day per year and low-elevation coastal zones (

Earth is “really quite sick now” and in danger zone in nearly all ecological ways, study says – “We are moving in the wrong direction on basically all of these”

By Seth Borenstein 31 May 2023 (AP News) – Earth has pushed past seven out of eight scientifically established safety limits and into “the danger zone,” not just for an overheating planet that’s losing its natural areas, but for the well-being of people living on it, according to a new study. The study looks not just […]
