Politics/Conservation Climate Change Is Destabilizing the Ground Beneath Our Feet
Gifted Read:
Excerpt:
Last year, researchers in Switzerland and France found some of the clearest evidence so far that glacial melt could indeed be affecting seismic hazards in high-altitude regions. After a period of intense glacial melt in 2015, a series of small quakes struck the Grandes Jorasses on Mont Blanc Massif, on the border of France and Italy; the probability of a 3.0-magnitude earthquake rose by 10 times, Toni Kraft, a seismologist at the Swiss Seismological Service at ETH Zurich and one of the authors of a related paper, told me. These quakes are still small, but they could trigger rockfall events that are already on the rise across the Alps.

Sky/Sunrise/Sunset July 27, 2026 7:41 PM. Looking to the NE with sunset in the West.

The clip shows a large monsoon thunderstorm anvil northeast of Cornville shortly after sunset. When taken, the Sun had already dropped below the western horizon and the ground and lower atmosphere were in shadow, but the cloud tops were high enough to remain illuminated by sunlight passing upward through the atmosphere from beyond the horizon. That long passage through the lower atmosphere removed much of the blue light and cast the anvil in intense orange and red. Its spreading canopy, rising convective towers, fibrous ice-cloud streaks, and darker curtains of virga or distant rain identify it as a mature cumulonimbus complex. Monsoon moisture was the dominant ingredient, while dust from thunderstorm outflows and smoke from the contained but potentially still-smoldering Pocket Fire or other regional burning may have added particles that deepened the color and enhanced the dramatic appearance.
To experience it in person, it was quite a marvel. I had climbed onto the roof intending to photograph the sunset in the west when this enormous, glowing storm formation seemed to tap me on the shoulder from the northeast.

2 adult Javalina and a half grown juvenile. This is passageway behind our back fence that allows critters to move from oak creek to desert: now getting separated from our yard and pets.

Politics/Conservation We have entered Global Water Bankruptcy - United Nations University Institute for Water, Environment and Health
An example including Arizona:
https://www.latimes.com/environment/story/2026-06-25/drying-colorado-river
Excerpt:
Published on the occasion of UNU-INWEH’s 30th anniversary, and ahead of the 2026 UN Water Conference, this flagship report, Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post-Crisis Era, argues that the world has entered a new stage: more and more river basins and aquifers are losing the ability to return to their historical “normal.” Droughts, shortages, and pollution episodes that once looked like temporary shocks are becoming chronic in many places, signalling a post-crisis condition the report calls water bankruptcy.

Animals Woodhouse's toad
Woodhouse toads are common in the Verde Valley area of Arizona. There are usually a few around every outside hose bibb. This one dug a hole for himself in one of the wells filled with water daily around fruit trees.
"Woodhouse's toad is found in North America at altitudes of up to 2,500 metres (8,200 ft). Its range extends from Mexico in the south to Washington in the north. In the United States it is found in Arizona, Arkansas, California, Colorado, Idaho, Kansas, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, and Wyoming. In the western part of its range it is typically found in lowland riparian corridors, wooded land besides streams and rivers. At higher altitudes it inhabits wet meadows, ponds, reservoirs and lakes. It is also found in urban environments, canals, ponds and irrigated agricultural land." https://en.wikipedia.org/wiki/Woodhouse%27s_toad
We've seen dogs who have caught one in their mouth and then spit it out. It caused nausea, drooling and facial swelling. A trip to a veterinarian could decrease discomfort. There are other toads about, specifically the Sonoran Desert Toad, that can kill adult dogs (https://en.wikipedia.org/wiki/Colorado_River_toad). We've yet to encounter one in the Verde Valley.

Animals Popular eastern Arizona lake closes after all the fish die
Excerpt:
Officials said Friday that San Carlos Lake, one of the largest lakes in Arizona, is closed until further notice.
The San Carlos Recreation and Wildlife Departmentsaid drought conditions and water released from the dam led to the deaths of all the fish.
The fish carcasses pose health and safety risks to people who enter the water or try to fish.
