CBS News — Stunning midwater creatures of the deep sea
You have to endure a half-minute commercial to see this 6-minute report on the fascinating footage captured by a high-tech marine science project of the Monterey Bay Aquarium.
Make sure to turn on full-screen viewing, if you can. Have you ever seen a bloody belly comb jelly?
We think you’ll agree it’s the most worthwile video you watched today.

CHEROKEE — The mountains of the Southern Appalachians were scraped clean a century ago. Headwater ecology changed as the canopy of trees disappeared that was shading the streams from all but the noonday sun. Rainstorms pushed dirt and rocks into the water muddying the feeding and breeding grounds of fish, amphibians and insects.
Lower down the mountain, newly cut pastures edged right up to the creeks while cows mucked up the once-pristine waters. Invasive bugs killed hemlocks, ash and other shade-giving trees. Pipes, culverts and dams blockaded streams and kept animals from cooler water.
Now they face an even more insidious foe — climate change.

WASHINGTON, D.C. — The green floater, a freshwater mussel native to the waters of Southern Appalachia, is now formally considered at risk of extinction due to the loss and fragmentation of its aquatic habitat.
The U.S. Fish and Wildlife Service determined the green floater, historically found in 10 eastern U.S. states, is likely to become endangered due to existing and emerging threats. The service is proposing to list the mussel as threatened under the Endangered Species Act.
The green floater is still found in its native range in North Carolina, Tennessee, Virginia and West Virginia. It is considered locally extinct in Alabama and Georgia.
While the species has strongholds in places, green floaters are rare in nearly 80 percent of the watersheds where they naturally occur. More than 75 percent of the nation’s native freshwater mussel species are endangered or threatened, considered to be of special conservation concern, or presumed extinct, according to USWFS.
The Earth’s sun is seen in this NASA image. Scientists said July might be the hottest month in 100,000 years.
KNOXVILLE — July 2023 has so far offered a scary look at global climate change around the world, and the month is already one for the record books.
This month will likely end up being the hottest July on record, globally speaking. That comes after quantitative conclusions from multiple scientists that the past week was, globally, the warmest in 100,000 years.
The Southern Appalachians have generally been spared from the heat settling on vast portions of the country and world, but that will soon change. The National Weather Service predicts higher than average temperatures flirting with 100 degrees in the Tennessee Valley next week. Record-breaking temperatures are possible. The average high temperature for July in Knoxville is 87 degrees.
KNOXVILLE — The Tennessee Valley Authority in coming years plans to add both natural gas and solar plants to its portfolio to meet what it says are rising energy demands.
TVA’s Board of Directors laid out the federal utility’s plan in a meeting at Norris Middle School in May. Environmentalists at a previous hearing criticized the utility’s focus on natural gas rather than renewables or other measures. Other people, largely tied to local power providers, argued that a switch to renewable energy would be unreliable.
TVA showed a map in a press release following the meeting, showing four proposed natural gas plants and two proposed solar plants. Two of those natural gas plants would be in Tennessee while the other two are planned for Alabama and Kentucky. It stated these new plants will total 3,800 megawatts. It also spoke of its System Operations Center, set to open in fall 2024 in Georgetown to manage the utility’s grid. TVA also stated a desire to research nuclear technologies.
“Our region is experiencing growth at six times the national average, which means we must invest in our current power system and build new generation so we can continue meeting our region’s demand,” said TVA president and CEO Jeff Lyash.
Several citizens criticized TVA’s focus on natural gas plants and new pipelines at the listening session May 9. Among them was Clinton resident and activist John Todd Waterman.

Thousands of senior Americans took to the streets in March in 30 states to demand that the country’s major banks divest from fossil fuels.
This “rocking chair rebellion” — organized by Third Act, a fast-growing climate action group focused on older Americans — shows that Baby Boomers are becoming a new force in the climate movement.
Third Act cofounder Bill McKibben, who joined a Washington, D.C., protest, says it’s unfair to put all the weight of climate activism on the shoulders of young people. It’s time for older Americans to take a central role.
“Young people don’t have the structural power necessary to make changes,” McKibben tells The Revelator. “But old people do. There are 70 million Americans over the age of 60. Many of us vote, we’re politically engaged, and have a lot of financial resources. So if you want to press either the political system or the financial system, older people are a useful group to have.”

There are questions that worry me profoundly as an environmental health and population scientist.
Will we have enough food for a growing global population? How will we take care of more people in the next pandemic? What will heat do to millions with hypertension? Will countries wage water wars because of increasing droughts?
These risks all have three things in common: health, climate change and a growing population that the United Nations determined passed 8 billion people in November 2022, which is double the population of just 48 years ago.
If the TV series “Dirty Jobs” covered animals as well as humans, it would probably start with dung beetles. These hardworking critters are among the insect world’s most important recyclers. They eat and bury manure from many other species, recycling nutrients and improving soil as they go.
Dung beetles are found on every continent except Antarctica, in forests, grasslands, prairies and deserts. And now, like many other species, they are coping with the effects of climate change.
I am an ecologist who has spent nearly 20 years studying dung beetles. My research spans tropical and temperate ecosystems, and focuses on how these beneficial animals respond to temperature changes.

If we needed more motivation to save our ailing rivers, it could come with the findings of a recent study that determined the biodiversity crisis is most acute in freshwater ecosystems, which thread the Southern landscape like crucial veins and arteries.
Rivers, lakes and inland wetlands cover 1 percent of the Earth but provide homes for 10 percent of all its species, including one-third of all vertebrates. And many of those species are imperiled — some 27 percent of the nearly 30,000 freshwater species so far assessed by the IUCN Red List. This includes nearly one-third of all freshwater fish.
How did things get so bad? For some species it’s a single action — like building a dam. But for most, it’s a confluence of factors — an accumulation of harm — that builds for years or decades.
VIENNA — Leonore Gewessler, Austria’s energy and climate minister announced that she would take the case to the European Court of Justice if the union’s executive proceeds with plans to include nuclear and natural gas in the EU taxonomy of sustainable finance.
About gas, Gewessler said that it releases unconscionable amounts of greenhouse gases. “Just because something is less bad than coal doesn’t make it good or sustainable.”
Regarding nuclear energy she said it has unpredictably high risks, referring to Chernobyl and Fukushima. She also mentioned as great concerns, the safe disposal of spent nuclear fuel and lack of a global solution for its final storage.

FORT MYERS BEACH — When Hurricane Ian hit Florida and killed at least 100 people, it was one of the United States’s most powerful hurricanes on record, and it followed a two-week string of massive, devastating storms around the world.
A few days earlier in the Philippines, Typhoon Noru gave new meaning to rapid intensification when it blew up from a tropical storm with 50 mph winds to a Category 5 monster with 155 mph winds the next day. Hurricane Fiona flooded Puerto Rico, then became Canada’s most intense storm on record. Typhoon Merbok gained strength over a warm Pacific Ocean and tore up over 1,000 miles of the Alaska coast.
