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 […]

What happens to a people when their land disappears – “We could lose our status as a state”

By Jonathan Watts 27 June 2023 (The Guardian) – Small island nations would rather fight than flee, but rising sea levels have prompted apocalyptic legal discussions about whether a state is still a state if its land disappears below the waves. The Pacific Islands Forum, which represents many of the most vulnerable countries, has invited international […]

Solar power bails out Texas grid during major heat wave – “This is what’s happening with 1 degree Celsius of global average warming. And we’re on track for 3 degrees.”

30 June 2023 (Reuters) – The Texas power grid comfortably met record demand during this week’s heat wave with abundant power supply from wind and solar plants, data from the grid operator showed. The Texas grid is a focus in the United States whenever it is tested by extreme weather after a catastrophic failure in […]

“Insane”, “Astonishing” jet stream leaves scientists “at a loss” for words

On 27 June 2023, Texas once again braced for a record spike in electricity demand as 110F heat spurred air-conditioning usage. An early heat wave gripped the second most-populous US state, buckling highways, stressing oil refineries and pushing up natural gas prices. At least two deaths were attributed to the searing temperatures and it was only expected to get hotter as the week wears on. It was not a new problem for Texas: The Lone Star State broke power-demand records 11 times in the summer of 2022. Graphic: Bloomberg

Texas power demand again forecast to peak amid Summer 2023 heat wave – “Texas is running about 2 degrees Fahrenheit warmer than it did during the 20th century”

26 June 2023 (Reuters) – Texas’ power grid operator on Monday again projected electricity use would break records this week as homes and business cranked up air conditioning amid soaring temperatures. The Electric Reliability Council of Texas (ERCOT), which operates the grid for more than 26 million customers representing about 90% of the state’s power […]

Drowned 16th-century church emerges from bottom of Mexico reservoir after drought – “What do I support my family with? Right now, I have nothing.”

By Aristos Georgiou 19 June 23 (Newsweek) – A 16th-century church has emerged from the waters of a reservoir in Mexico amid a drought. The colonial-era Dominican church is located in Quechula in the southern Mexican state of Chiapas. The building had been almost entirely submerged since 1966 when a dam was built on a […]

Nearly 170 people have died in the last few days in northern India as searing heat combined with lack of preparedness and resources at local hospitals is resulting in a constantly increasing body count. According to local news reports and health officials in Uttar Pradesh state, 119 people have died and in neighboring Bihar state, government officials say 47 people have died due to heat-related illness.

Days of sweltering heat, power cuts in northern India overwhelm hospitals as death toll climbs – “So many people are dying from the heat that we are not getting a minute’s time to rest. On Sunday, I carried 26 dead bodies.”

By Rajesh Kumar Singh, Piyush Nagpal, and Sibi Arasu 19 June 2023 BALLIA, India (AP News) – A scorching heat wave in two of India’s most populous states has overwhelmed hospitals, filled a morgue to capacity and disrupted power supply, forcing staff to use books to cool patients, as officials investigate the number of deaths that […]

Global warming at the center of recent California wildfires – “We show that nearly all of the observed increase in burned area in California over the past half-century is attributable to human-caused climate change”

By Anne M. Stark 12 June 2023 (LLNL) – Summer wildfire seasons in California routinely break records. The average summer burn area in forests in northern and central portions of the state have increased fivefold between 1996 and 2021 compared to between 1971 and 1995. Although the drivers of increased temperature and dryness are known, […]

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 […]

June 2023 temperatures briefly passed key climate threshold – “We’ve loaded the climate system. No one should be surprised when we set extended global records. 1.5°C is coming fast; it may already be here.”

BERLIN, 16 June 2023 (AP) – Worldwide temperatures briefly exceeded a key warming threshold earlier this month, a hint of heat and its harms to come, scientists worry. The mercury has since dipped again, but experts say the short surge marked a new global heat record for June and indicates more extremes ahead as the […]
