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 […]

High river temperatures to limit French nuclear power production – Hot weather likely to halve available power from two plants

By Forrest Crellin 12 July 2023 PARIS (Reuters) – Output restrictions are expected at two nuclear plants along the Rhone River in eastern France due to high temperature forecasts, nuclear operator EDF (EDF.PA) said, several days ahead of the similar warning last year, but affecting fewer plants. The hot weather is likely to halve the available power […]

“Death coming out of the ocean”: Red tide killing California sea lions, dolphins – “I have been a marine mammal veterinarian for 35 years, and this is definitely the worst in my professional lifetime”

By Amanda Lee Myers 8 July 2023 (USA TODAY) – Jalapeño the sea lion turned up on a crowded California beach in a daze, experiencing seizures and heavily pregnant. Instead of giving birth in a remote location like sea lions prefer, Jalapeño had her pup on Southern California’s Hermosa Beach on a busy Saturday, surrounded by throngs […]

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 […]

Seaweed full of flesh-eating bacteria hitting Florida, creating a “perfect pathogen storm”

By Jess Thomson 30 May 2023 (Newsweek) – The massive blob of seaweed creeping across the Atlantic Ocean toward Florida may contain deadly flesh-eating bacteria. The 5,000-mile wide clump of seaweed is made up of sargassum seaweed, which has bloomed massively to form the “Great Atlantic Sargassum Belt.” A study from Florida Atlantic University published […]

Deep ocean currents around Antarctica headed for collapse – “Such profound changes to the ocean’s overturning of heat, freshwater, oxygen, carbon, and nutrients will have a significant adverse impact on the oceans for centuries to come”

By Kathy Gunn, Matthew England, and Steve Rintoul 25 May 2023 (The Conversation) – Antarctica sets the stage for the world’s greatest waterfall. The action takes place beneath the surface of the ocean. Here, trillions of tonnes of cold, dense, oxygen-rich water cascade off the continental shelf and sink to great depths. This Antarctic “bottom […]
