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.

25 Years, 25 Images – Celebrating twenty-five years since the launch of NASA Earth Observatory (EO) on April 29, 1999 and the EO website with a slideshow!

Insurance Companies: Consider Climate Risk Events As “Constant Threats” - Up until recently, most people weren’t concerned with how their ability to be insured would change — until catastrophic climate disasters began to wreak havoc on communities around the country. I am very glad I don’t own property in Florida or south Texas or California!

New Constitution Gardens (in Washington DC) Will Be a Biodiversity Mecca – Glad there are plans to improve the area. I always enjoyed it even though it was beginning to show its age in the 1990s and early 2000s when we lived in Maryland and visited with our young daughter.

Stunningly Preserved Ancient Roman Glassware Turns Up in a French Burial Site – Found during construction of a new housing development. I am always amazed at how durable a material we normally thing of as ‘breakable’ can be!

Cicada dual emergence brings chaos to the food chain - Cicada emergences can completely rewire a food web. For predators, these emergences are a huge boom in resources. It's basically like an all-you-can-eat buffet for the hungry predator. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities. Scientists have found that wild turkeys, for example, will capitalize on the bounty, leading to a wild turkey boom. However, caterpillars, usually preyed on by birds, were left off the dinner menu and their numbers more than doubled. This in turn led to damage to trees caused by out-of-check caterpillar populations. Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.

Earlier Springs Cause Problems for Birds - As climate change warms our planet, causing spring to arrive weeks earlier than it has historically, birds are struggling to keep up. It’s not just the green vegetation they miss, but the pulse of protein-rich insects many bird species consume on both their breeding grounds and their migratory stop-over points. Birds will still breed but not quite as successfully because food will be more limited. Instead of chicks hatching as insect populations boom, those chicks may catch the end of the insect pulse.

Why you should let insects eat your plants – I skew the additions to my yard toward native plants….and let whatever insects show up enjoy. My community sprays for mosquitos so there probably is some reduction of other insects because of that. But there are enough left to support a barn swallow (and other insect eating birds) flock in our community.

Quantifying U.S. health impacts from gas stoves - Even in bedrooms far from kitchens, concentrations of nitrogen oxide frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off. All the houses I’ve purchased as an adult, have had electric stoves/ovens except one and I only lived there for 3 years. But – in the 1950s and 1960s, my parents had gas stoves/ovens. Back then the houses were not as airtight as they are now so that might have reduced our exposure; my sisters and I never had asthma or other breathing problems, fortunately.

Inside the exquisite Tibetan monasteries salvaged from climate change – Built in the 1300s, the monasteries are impacted by a significant increase in the intensity of storms and rainfall across the region. Increased rainfall saturates the rammed-earth buildings, as moisture in the soil is drawn upward into the walls, leading to issues such as leaking roofs and rising damp. Local people have gained diverse skills, from reinforcing walls to crafting metal statues and restoring paintings. Over the past 20 years, a team of local Lobas trained by Western art conservationists have replaced the old, leaky roofs of the temples with round timbers, river stones, and local clay for waterproofing, and have restored the wall paintings, statues, sculpted pillars and the ceiling decorations, giving these centuries-old monuments a new life.

Possible Conch Shell Communication in Chaco Canyon Explored - The settlements of Chaco Canyon that spread around each sandstone great house fit into the sphere of sound produced by conch shell trumpet blasts; perhaps the settlements were designed to ensure that every resident could hear the notifications.

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.

Touching Image of Intergenerational Love Wins Black and White Minimalist Photography Prize – Minimalist…but powerful.

How an English castle became a stork magnet – 30 White Storks from a rescue project in Poland introduced in the rewilded habitat at Knepp Castle in southern England in 2016. At one point, storks even built nests on Knepp Castle itself although they usually build their nests in the crown of huge oak trees. The young storks started migrating in 2019. The colony has grown to about 80 storks…and is the first breeding colony in Britain in 600 years.

Evidence for Domesticated Chickens Dated to 400 B.C. - A study of eggshell fragments unearthed at 12 archaeological sites located along the Silk Road corridor in Central Asia.

Noisy Summer Ahead for U.S. as Dueling Broods of Cicadas Emerge - It is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House. Mating season will last until July.

California’s Live Oaks in Focus - Some centuries old, the oaks are magnificent giants that can grow up to 100 feet tall and are what remains of a forest that once blanketed the region.

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Analyzing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health. Microparticles from car tires, pesticides from farmers' fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach.

Cars & Road Trips Made a Huge Difference in Women’s History – One of the first cars ever built got taken by a woman, without permission, on the world’s first road trip! Bertha Benz wanted her husband’s invention to be seen out in the country so people would buy it, but her husband Karl Benz was being timid about it. So, she took the car out on a road trip with her kids.

Common household chemicals pose new threat to brain health - The new study discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells. Loss of oligodendrocytes underlies multiple sclerosis and other neurological diseases. They identified chemicals that selectively damaged oligodendrocytes belong to two classes: organophosphate flame retardants and quaternary ammonium compounds.

The Soundtrack of Spring on the Platte River – Sandhill cranes staging last month along the Central Platte River in Nebraska. So many birds….lots of sound.

These Are the Most Polluted National Parks – Many national parks are suffering from air pollution and facing threats stemming from human-caused climate change. 98 percent of parks suffer from visible haze pollution, while 96 percent are grappling with ozone pollution that could be harmful to human health. Four of the nation’s parks with the unhealthiest air are in California: Sequoia and Kings Canyon National Park, Joshua Tree National Park, Mojave National Preserve and Yosemite National Park. Another California site, Death Valley National Park, also made the top ten list. 57 percent of national parks are facing at least one threat stemming from climate change that could permanently alter its ecosystems, with many parks grappling with multiple issues at the same time. Invasive species were the most prevalent issue.

Cicada Aftermath

The Brood X adult cicadas are gone; the outdoors is quiet in comparison to the way it was a month ago. The trees are showing the impact of the large numbers of cicadas that emerged this year…but not all the trees were impacted the same. Our oak seems to have the most small-stem breakage from the cicada eggs deposited under the bark…the larvae hatching and dropping to the ground. The stems split and the leaves past the split die. The condition is called ‘flagging.’

Some of the leaves are already falling off the tree; they’ll be mulched into the yard the next time we mow.

There are other insects that enjoy our oak. I noticed that some of the leaves on the ground have holes in them. Without the cicadas, the leaves probably would have stayed green and on the tree for the rest of the summer.

The sycamore is impacted to a lesser degree.

It appears from the yard that the small branches are falling off more quickly than the oak’s.

I took some zoomed pictures of the sycamore branches. The color and shapes appeal to me.

Soon the aftermath of the Brood X will all be underground….the larvae beginning their 17 year journey.

There was a story in the news of some research into the blue jay and grackle die off recently….looking at whether the fungus that seemed more prevalent in the cicadas this year might have impacted the juvenile birds that ate them. The die off occurred in the same areas where Brood X emerged.

Enjoying Home

There is so much to enjoy about just being home. Even yard work is appealing! On the third day back – I was out early with the goal of cleaning out the front flower beds. I didn’t have enough energy to set the goal to completing the job…instead strived for two wheelbarrow loads back to the forest/brush pile. It was not too difficult and my long sleeves/gauntlet gloves protected my hands from poison ivy (there might have been one plant) and blackberry thorns.

I took short breaks to photograph tiny mushrooms, blooming clover (the clover we planted last fall in the problem areas of our yard is growing well), cicadas at every turn, and tiny blooms on our bushes.

I already have plans for another round in the front yard and then will begin work on the chaos garden (which is completely wild this year).

My husband and I have enjoyed some short ‘field trips’ to Brookside Gardens and to view the recent partial solar eclipse. One field trip per week is probably about right for us – even though we are still spending most of our time at home. We are choosing venues where there are outdoors…usually in the morning (sometimes very early)…where there are unlikely to be crowds. There are a lot of places we’ve enjoyed in the past that we haven’t been to for over a year!

Since I knew I would be going to Texas several times this summer, I opted to not sign up for the CSA this year; I’m going to the Farmers Market instead which happens ever Sunday. It’s worked well so far. I got spinach, broccoli and snap peas the first week…spinach, squash, and artisan bread with pecans and golden raisins the second week (the spinach is for green smoothies). I’m still a little overwhelmed with veggies since my husband doesn’t eat them…but I know how to freeze any that I have left over!

Last Sunday when I was pulling into the driveway after my trek to the Farmers Market, I noticed a lot of cicadas on the day lily leaves growing around our oak tree. Do you see three in the picture below? The temperature might have still been a little cool for them to be flying around. One of the things I like about our yard is how much wildlife we have around!

I picked up some cicada carcasses from the driveway and did a little macro photography after I put away the produce.

I also brought in some stalks of day lily buds; it’s the same every year at this time – cutting the buds as soon as they are big enough to open in water…before the deer eat them!

I enjoy just about everything about being home…rejuvenating myself for my next foray away in mid-July.
