Study finds climate risk to crops greater than thought – Simultaneous harvest failures across major crop-producing regions threaten global food security – “These types of concurring events are really largely underestimated”

By Kelly Macnamara 4 July 2023 (AFP) – The risks of harvest failures in multiple global breadbaskets have been underestimated, according to a study Tuesday that researchers said should be a “wake up call” about the threat climate change poses to our food systems. Food production is both a key source of planet-warming emissions and […]

Child labor in America is back and it’s as chilling as ever – “You’re taking children from another country and putting them almost in industrial servitude”

By Steve Fraser 13 July 2023 (The Nation) – An aged Native American chieftain was visiting New York City for the first time in 1906. He was curious about the city and the city was curious about him. A magazine reporter asked the chief what most surprised him in his travels around town. “Little children working,” the […]

Summer in the Southern U.S. is becoming unbearable – “This is how it’s going to be: Things will get hotter, storms will get worse, wildfire smoke will get more common. All the while, the ruts of inequity will be worn deeper, the same people time and time again placed on the front lines of catastrophe.”

By Olivia Paschal 1 July 2023 (The Atlantic) – A few weeks ago, as the first wave of smoke from the Canadian wildfires rolled south, I was getting ready to drive from Charlottesville, Virginia, about 18 hours west to my hometown of Rogers, Arkansas, to visit family. I figured that by the time I hit […]

Humans have pumped so much groundwater that we’ve nudged the earth’s spin – “As a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise”

WASHINGTON, 15 June 2023 (AGO) – By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study published in Geophysical Research Letters, AGU’s journal for short-format, high-impact research with […]

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 […]

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 […]

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 […]

Europe is struggling with a precarious water situation ahead of another drought-riven summer in 2023 – “A few years ago, I would never have imagined that water would be a problem here in Europe, especially in Germany or Austria”

By Sam Meredith 5 June 2023 (CNBC) – European policymakers are battling to get to grips with a growing water crisis ahead of what researchers fear could be yet another climate crisis-fueled summer of drought. Water resources in Europe are growing increasingly scarce because of the deepening climate emergency, with record-breaking temperatures through spring and a historic winter […]

Kansas wheat harvest in 2023 expected to be historically small due to two-year drought

By Morgan Mobley 5 June 2023 (KCTV) – Kansas has been called the country’s breadbasket. Now, wheat farmers in the state will reap their smallest harvest in more than 60 years. This will go directly down the chain, from farmers to consumers at the grocery store. Kansas flour mills will likely have to buy wheat […]
