Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

• The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

• At night, the cranes move to the Platte River for safe roosting in the shallow water.

• Sandhill cranes are the most numerous of the world’s crane species.

• In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

• Increase tree percentage in parks and green spaces

• Provide shade on sites

• Use plant materials and water instead of hardscape

• Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.

Extreme Weather is the “New Norm” - There is high confidence that human induced climate change from greenhouse emissions, is the main driver.

A Visit to North America's Only Authenticated Viking Site - L’Anse aux Meadows National Historic Site (in Newfoundland), the only authenticated Viking site in North America. Credit for this discovery in the 1960s goes to Norwegian explorer/writer Helge Ingstad and his archaeologist wife Anne Stine.

Earth’s hottest month: these charts show what happened in July and what comes next – The intense heat this summer has killed Saguaro cactus!

Ötzi the Iceman’s Genome Sequenced – 90% of his ancestry came from Anatolian farmers. Genome analysis revealed he had high skin pigmentation, dark eyes, and male pattern baldness!

Common wristbands 'hotbed' for harmful bacteria including E. coli, staphylococcus – I am glad the band on my Garmin is metal since it likely harbors a lot less bacteria than a plastic, rubber, cloth, or leather band. However, I still need to get in the habit of cleaning it more often.

Fully Intact Giant Panda Skeleton Discovered in Chinese Emperor’s 2,000-Year-Old Tomb – There was also an Asian taper in the tomb.  The article suggests that perhaps the animals were included in the tomb as a part of a replica royal garden.

Medications for chronic diseases affect the body's ability to regulate body temperature, keep cool - Medications used to treat common chronic conditions, like blood thinners, blood pressure drugs, Parkinson's disease/Alzheimer's medications, and some chemotherapy drugs, can make it harder for the human body to handle hot weather by reducing its ability to sweat or increase blood flow to the skin. Hopefully doctors will become more aware of this issue – particularly for their elderly patients that are already at increased risk because of their age for heat related issues.

Trapped: Australia’s extraordinary alpine insects are being marooned on mountaintops as the world warms – The grasshopper with the turquoise exoskeleton snagged my attention. This movement up mountains and then becoming marooned must be happening around the world.

Chromium replaces rare and expensive noble metals – Osmium and ruthenium replaced with, much more abundant, chromium? More research is needed, but it might be possible.

Photos of the Week – August 13, 2023 from the Prairie Ecologist – Another example of enjoying some photography even when it is hot and humid!

Risk of fatal heart attack may double in heat wave and high fine particulate pollution days – A study from China that included 202,000 heart attach deaths.

July Was Likely Earth’s Hottest Month on Record – The last sentence of the article: ‘Well, this is probably one of the coolest summers you’ll ever see in your life.’ ... It is quite scary to put it this way.

Climate Change Temperatures Killing Death Valley's Bristlecones – 70% mortality rate over the past decade.

The Australian town where people live underground – Coober Pedy…where most of the people live underground in abandoned opal mines or intentionally excavated spaces!

Looking Down on the Andes – Pacific Ocean, Atacama Desert, Andes…Chile, Argentina, and Bolivia. Image taken from the International Space Station.

Supermarkets to the Rescue — Coles Joins Virtual Power Plant – A grocery chain in Australia. Maybe some supermarkets (and other big box stores) in the US will do similar things.

In a Chilean Forest Reserve, the Remarkable Darwin’s Frog Endures – The endangered frog is a smallish leaf mimic with a pointy nose. Males whistle to attract mates. After females lay their eggs on the ground, males swallow them, holding them in their vocal sac as the young metamorphose. Six to eight weeks after hatching, small adults make their exit through the males’ mouths!

Moths With 11-Inch Tongues? - More than 150,000 recognized moth species, though likely another 150,000 or so, give or take, remain undescribed. Many of these species feed birds and bats like some form of “aerial plankton.” Out of the hundreds of caterpillars one moth might produce, few survive to metamorphose into moths. But those that do provide a critical service both as food for nighttime predators and as pollinators, often evolving to be the only ones that can get the job done. Every species of yucca in North America, including the famous Joshua Tree, requires pollination exclusively from yucca moths.

Spooky, stealthy night hunters: revealing the wonderful otherworld of owls - Owls occur across all continents other than Antarctica, spanning an environmental gradient from the freezing Arctic (home of the stunningly beautiful snowy owl, of Harry Potter fame) to the hottest deserts (home of elf owls).

What to know about beech leaf disease, the 'heartbreaking' threat to forests along the East Coast – I remember this entering into Master Naturalist conversations in Maryland before the COVID-19 pandemic…but the cause was a total mystery at that point. It was interesting to get an update. There is still no known way to control or manage disease, but progress has been made; large numbers of foliar nematodes cause the disease (the interfere with chlorophyll production and the trees starve). It hasn’t been that long ago that the Emerald Ash Borer killed almost all the ash trees…before that wooly adelgid killed the Eastern Hemlocks….and earlier, in the mid-1900s, the American Chestnut succumbed to blight. The eastern US forests are very different than they were 100 years ago and the pace of diseases seem to be increasing.

An elegant enigma – A shipwreck discovered 30 feet below the surface 15 years ago…what we know (and don’t know) about it after study of the 1,500 objects recovered including textiles in 4 chests. The name of the ship is still unknown but the construction indicates it was a Dutch trader constructed around 1645 and sank around 1660.

At Peru temple site, archaeologists explore 3,000-year-old 'condor's passageway' – A 3,000 year old sealed corridor in a massive temple complex built by the ancient Chavin culture.

Does Nature Need a Trigger Warning? – A thought provoking post. Predators must be part of our conservation actions…and need to be valued as they are rather than simplistically.

Two-Hundred Years of Written Observations of Kīlauea's Summit Activity – On August 1, 1823, an English missionary visited the summit and published his observations (I found the book online -available on Internet Archive…Chapter 6 begins on page 121…image below). Mark Twain visited in 1866 and trekked across the caldera floor to Halema’uma’u, watching “a heaving sea of molten fire of seemingly limitless extent.” There are several links in the article that are worth following. My favorite is the USGS Views of a Century of Activity at Kilauea Caldera – A Visual Essay.

How Texas is racing to thwart the heat  - Unfortunately, planning for heat is not as well-developed in the US as planning for other hazards like flooding so many cities are scrambling to take proactive measures to cool their streets down and protect people from the dangerous impacts of overheating. In urban heat islands, temperatures can be up to 20 degrees Fahrenheit hotter than less populated areas. Austin, TX has a climate resilience plan that includes strengthening emergency response and future-proofing new facilities and infrastructure. It also developed an urban forest canopy for the city to ensure cool outdoor spaces. The city has now applied for a United States Department of Agriculture (USDA) grant to plant more trees after finding the tree canopy coverage was helping Austin to adapt to hotter temperatures. In 2021, San Antonio became the first city in Texas to participate in a pilot project to lower pavement temperatures by applying a coat of paint that reflects the sun's rays. I was disappointed that other large cities in Texas (like Dallas and Houston) were not mentioned in the article. My impression of Dallas is that there is a lot of concrete.

Detecting spoiled foods with LEDs – A potential improvement in non-invasive monitoring of fruit and vegetable freshness.

Joshua trees are dying. This new legislation hopes to tackle that – A compromise law…sets up a conservation fund and requires the state to develop a conservation plan and companies to obtain a permit from the state to cut down or relocate existing trees.

The looming 840,000 ton waste problem that isn't single-use plastics – Carbon and glass fiber composites used in wind turbine blades, hydrogen tanks, airplanes, yachts, construction, and car manufacturing. "This is a huge opportunity," said Dr Wei. "And not only because various modes of recycling are cost-effective and minimally impactful on the environment. In an era of mounting supply chain disruptions, local recycled products can provide a more immediate product when compared to imports and create a burgeoning advanced manufacturing industry."

National Park Visitors Warned to Be "Prepared to Survive" Heat – My husband and I have avoided trips to the western national parks in summer since the 1980s…primarily to avoid crowds but now ‘excessive heat’ is part of our rationale too.

The ocean's color is changing as a consequence of climate change – The color shifts have occurred in 56% of the world’s ocean based on analysis of data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite, which has been monitoring ocean color for 21 years. Tropical oceans have become steadily greener. Changes in color reflect changes in plankton communities, that will impact everything that feeds on plankton. It will also change how much the ocean will take up carbon, because different types of plankton have different abilities to do that.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The ground is deforming, and buildings aren’t ready – Underground climate change in urban areas where heat islands underground cause enough expansions and contractions to damage building foundations…particularly in older buildings.

How noise pollution impacts nature – A study out of Vail, Colorado, showed that increased trail use by hikers and mountain bikers disturbed elk so much the cows birthed fewer calves. Another out of Grand Teton National Park showed that backcountry skiers scared bighorn sheep during winter when food was scarce, with potentially lethal consequences.

Hospital understaffing and poor work conditions associated with physician and nurse burnout and intent to leave - The study from the University of Pennsylvania School of Nursing found that physicians and nurses, even at hospitals known to be good places to work, experienced adverse outcomes during the pandemic and want hospital management to make significant improvements in their work environments and in patient safety. The solutions to high hospital clinician burnout and turnover, they say, are organizational improvements that provide safe workloads and better work-life balance NOT resilience training for clinicians to better cope with adverse working conditions.

The simple ways cities can adapt to heatwaves – Heat monitoring and planning is become more important for cities…the climate emergency in cities is a health emergency.

New biodegradable plastics are compostable in your backyard – New plastic made from blue-green cyanobacteria that isstronger and stiffer than previous plastics from the same raw ingredient. They can be recycled…but also degrade rapidly in the environment.

Giant Hand Axes Discovered in England Point to Prehistoric Humans’ ‘Strength and Skill’ – More than 300,000 years old perhaps from an interglacial period. Early Neanderthal people inhabited Britain then…and maybe other archaic human species too.

Germs, genes and soil: tales of pathogens past – DNA sequencers and powerful computational tools…applied to ancient microbes…probing their role in human history. This article describes how the work is done, ethical considerations…using examples of what has been accomplished so far. The field of archaeogenetics is just beginning.

Back from the Dead: New Hope for Resurrecting Extinct Plants – There is a global effort to digitize herbaria specimens which had helped identify holdings of extinct plants…sometimes finding seeds. And then the challenge is how to best attempt to grow old seeds.

Pain risk varies significantly across states – Pain due to arthritis varies geographically in the US – with the moderate to severe pain being 23% in West Virginia vs 7% in Minnesota.  There is also a difference between people that did not complete high school…and those who obtained at least a bachelor’s degree – with the delta being greatest in West Virginia, Arkansas, and Alabama. There is a need to focus on the macro-level policies (i.e. generally at the state level) while continuing current individual interventions.

The Acropolis Adopts Crowd Control Measures for the First Time – The post-pandemic travel surge is overwhelming at some places – including the Acropolis!

Pregnant women are exposed to cancer-causing chemicals in dishware, hair coloring, plastics, and pesticides, study reveals – Something else for pregnant people to be anxious about. I wish these studies had a stronger component about how to reduce exposure, but it seems that the problematic chemicals are very pervasive.

The U.S. diet is deadly. Here are 7 ideas to get Americans eating healthier – These ideas a geared to making it easier for individuals to make healthier choices. Right now…it seems that the push is toward unhealthy food choices.

Cool planning for a hotter future – Actions we need to take to achieve the ‘late century rapid action’ maps.

Low physical function after age 65 associated with future cardiovascular disease – Individuals were assessed for walking speed, leg strength, and balance….and the scores were more predictive of cardiovascular disease risk than the traditional risk factors that work for middle-aged people (high blood pressure, high cholesterol, smoking or diabetes).

On “Trash” Birds: Rethinking How We Label Common Species – There is no such thing as a ‘trash’ bird or any species. They are all just part of our world!

Can These Lights Make Crosswalks Safer for Pedestrians Distracted by Their Phones? – People shouldn’t be walking while looking at their cell phones more than where they are headed….but they do and maybe Hong Kong is ahead of us in developing a solution to reduce tragedies.

Is Breadfruit the Climate Change-Proof Food of the Future? – Not a food I know anything about…it’s not in our grocery stores yet. I looked at some recipes and it seems like it would be a versatile addition to our diet.

Archaeologists Call on UNESCO to Protect the Hagia Sophia – It’s sad when pieces of architectural history are not maintained. Hopefully this call will help organize what is needed to preserve Hagia Sophia.

Heat waves + air pollution can be a deadly combination: The health risk together is worse than either alone – There are ways to stay safe…but it is not possible for everyone all the time. We need to address the underlying issues for the health of everyone. Often – addressing air pollution also is step in a good direction of climate change as well.

See the Incredible Sunflower Superbloom in North Dakota – Wow! Maybe a trip to North Dakota some July/August should be added to our list of road trips we want to make.

We asked children how they experienced poverty. Here are 6 changed needed now – This was a study done in Australia. I wonder how applicable these findings are around the world.

The identical twins who discovered their secret sibling – An adoption agency that separated twins for adoption in the 1960s…and the researchers that were part of that process. Fast forward to 2022.

Heat wave reveals 17th-century English gardens – Longleat Gardens….a whisper of the past…from before the transition to natural parkland in the 18th century.

Is this the end of DC’s most-beloved hidden landmark? – I’ve never seen (or known about) the Capitol stones in Rock Creek Park but I’ve noticed the old columns dating from the same period that are in the National Arboretum. They are certainly a landmark!

Painted Bunting: The Fun of Local Bird Quests – I remember seeing some painted buntings at a Florida National Wildlife refuge and an indigo bunting under my bird feeder in Maryland. They are special birds!

Colorful solar panels could make the technology more attractive – Color is a lower priority than efficiency for me, but it could be very important in some applications.

A Beginner’s Guide to Butterfly Watching – I wish there were more butterflies to watch! It seems like every year there are fewer of them around.

Taming Tomorrow’s Wildfires – There is a wildfire burning somewhere in the US all the time recently. It’s important that we make changes to reduce their devastation.

New drug candidate fights off more than 300 drug-resistant bacteria – Antibiotics have been around for my whole life…but there is always the discomfort that more bacteria are becoming resistant…and there could come a time that the pre-antibiotic killers will beginning killing people again. I’m glad there are new drugs in development to take up the fight.

Olmec contortionist Reliefs Uncovered in Mexico – Artifacts from a civilization known for colossal head sculptures….hints of their culture.

Road trip: Missouri to Texas

It is a 6.5-hour drive from my house in Missouri to my Parents’ in Texas. Only the first few hours are interstate so there are not the typical highway rest stops along the way. I left early enough that the Oklahoma welcome center on I44 was not open yet (doesn’t open until 8:30 AM) so my first rest stop was the Will Rodgers rest stop along the turnpike; I also bought gas there (thrilled that it was below $4/gallon). It is not my favorite place since the rest rooms always seem crowded and not very clean.

The second stop was a McDonalds for a breakfast burrito – my favorite road trip breakfast – which I ate rather clumsily going down the road (cheese dribbled on my lap!).

The third stop was another toll road plaza. None of the three rest stops were visually appealing. Fortunately, the Texas Welcome Center on US 75 just across the Red River has some interesting plantings. I did some macro photography.

I noticed that Oklahoma was greener than Missouri. They must have gotten more rain recently than we have in Southwestern Missouri. The day got hotter and hotter as I drove…passing 100 degrees at 11:42 PM.

A lesson learned from this trip: the back of my car with the slopped hatchback is not cooled very much by the air conditioner; I’ll place my luggage in the back seat rather than the far back when I am driving on a hot day.

Amazing Photo of Wisteria Trees Looks Like a Fireworks Display – Pictures from Japan’s Ashikaga Flower Park.

New Mexico Wildfire Spawns Fire Cloud – A pyrocumulonimbus cloud formed; the vertical plume reached the tropopause….an altitude of about 12 kilometers.

Heatwaves are altering our everyday lives – The new normal but we aren’t very well prepared for it; there are some obvious adaptations that are needed – particularly to electrical networks. No one wants infrastructure to fail at a critical time.

Well-preserved iron age arrow discovered in Norway – The arrow was recovered from a glacier…iron arrowhead, sinew, tar, thread, shaft, and feather fletching was preserved. It is about 30 inches long.

Rigid waterproof coating for paper aims to reduce our dependence on plastic – Interesting…would be great if it could speed the transition away from plastic for food packaging particularly. The article said the chemicals break down over time into harmless components…but didn’t say how long that took.

Chemicals that linger for decades in your blood – So many chemicals introduced in my lifetime are probably still in my blood. I can remember the spraying of DDT for mosquitoes in the ‘60s….one instance particularly of the straying truck going down the farm road near my grandparents house as we played in the back yard. How much of my exposure do I still have…did I pass along to my daughter?

Ultraviolet light reveals radiant hidden beauty of flowers – A project during the COVID-19 pandemic…beautiful results.

Archaeologists Unearth 3,000-Year-Old Giant Statues in Sardinian Necropolis – Over 7 foot tall…with almost emotionless expression, blocky nose and deep-set eyes. The two found most recently were boxers but about two dozen others have been found since the mid-1970s: 16 boxers, 4 archers, and 5 warriors.

Top 25 birds of the week: May 2022! – Bird appreciation….a source of beauty in the world.

Disparities in natural gas leak prevalence in US urban areas – Why can’t pipeline companies do better…not wait around until regulation requires them to do it? We should be more critical of the companies that they are not actively reducing leaks in their pipelines.
