Excerpt: ...Heron’s Nest, a new cottage community in Shallotte, N.C., ...calling itself an “environmental village,” ...homes were reasonably priced, between $300,000 to $400,000. ...each house came with a three-kilowatt rooftop solar system, which would reduce their carbon footprint and cut their utility bill by a third. ...the 31-home community, ...North Carolina’s first residential “microgrid” development. ...A microgrid is a network of buildings that essentially acts as a miniature power grid. It can operate outside of the larger municipal electrical system by ensuring backup power for the entire development, which can be produced by a solar array system and stored in a battery. ...The U.S. Energy Department estimated that there were more than 450 operational microgrids in the United States in 2022. ...The California Public Utilities Commission...recently approved a $200 million program to bring community microgrids to disadvantaged and tribal communities that are vulnerable to power outages. Americans experienced an average of about seven hours of power interruptions in 2021. It was more in Louisiana, Oregon and Texas, where residents went without power anywhere between 20 and 80 hours during the year. Two-thirds of North Americans are at risk of energy shortfalls this summer, according to the North American Electric Reliability Corporation, a nonprofit regulatory authority. ...developers are finding that energy-resilient homes and communities are powerful marketing tools to lure buyers and renters....

Lost history of Antarctica revealed in octopus DNA

https://www.science.org/content/article/lost-history-antarctica-revealed-octopus-dna By ERIK STOKSTAD .  Excerpt: Some 100,000 years ago, scientists believe Antarctica’s massive western ice sheet collapsed, temporarily opening waterways between a trio of seas surrounding the continent. New evidence for that scenario comes from a surprising source: octopus DNA. ...About 129,000 to 116,000 years ago, a warm spell called the last interglacial gave our planet a brief break in between several million years of ice ages. The average temperature of the planet was about 0.5°C warmer than it is today—and climate projections predict it will be again within decades. The global sea level was also 5 meters to 10 meters higher than current levels. Many scientists believe  the collapse of the West Antarctic Ice Sheet and consequent melting could have been a primary reason . ...The findings are consistent with growing geological evidence supporting the ice sheet collapse....

Where Glaciers Melt, the Rivers Run Red

By -
By Mitra Taj , The New York Times.  Excerpt: As the glaciers of South America retreat, the supply of freshwater is dwindling and its quality is getting worse. Dionisia Moreno, a 70-year-old Indigenous farmer, still remembers when Shallap River, nearly 13,000 feet up in the Cordillera Blanca, brought crystal clear water brimming with trout to her village, Jancu. “People and animals alike could drink the water without suffering,” she said. “Now the water is red. No one can drink it.”....  Full article at https://www.nytimes.com/2024/11/19/science/peru-glaciers-water-pollution.html .

The first people on Tasmania brought fire and forever changed the land

By -
By Warren Cornwall , Science.  Excerpt: More than 41,000 years ago, humans traversed a strip of land that once joined the mainland of Australia to what is today the island of Tasmania, called Lutruwita by its Indigenous inhabitants today. The first humans to reach this land brought a tool they used to transform the landscape and that left the first lasting marks of their presence: fire. Thanks to layers of sediment that formed year by year along the bottom of a lake on a small island off the northeastern tip of Lutruwita, scientists have for the first time chronicled the region’s history of vegetation spanning more than 50,000 years. They found  a surge in fires starting about 41,600 years ago , the researchers report today in Science Advances, the same time as falling sea levels opened a dry corridor allowing humans to migrate to the island. ...The findings come at a time of growing interest in reviving a traditional burning culture on Lutruwita. Aboriginal communities a...
