Then and Now – Heating

During the 1960s, the heating where I lived in Texas transitioned from electric wall heating to gas powered central heating. Both had to work harder because the windows of the houses were single paned and had little insulation. I remember that my grandparents’ houses were often colder in the winter than mine was. My paternal grandparents’ farmhouse had gas burning (probably propane) stoves in each room and my maternal grandparents’ house had gas burning (probably natural gas) floor furnaces; in those houses, the kitchen during meal prep time, was the warmest! Prior to the advent of thermostats, the controls on the heaters were tweaked manually.

My house now has two central heating furnaces (2 zones) – one natural gas and one electric. Within the next 5 years, we will be transition to electric powered heat pumps. The house has well-sealed doors and double pained windows….and was well insulated when it was built in 1999. It has two gas fireplaces which we haven’t used; the gas is turned off and we have sealed the vents with magnetic strips to stop the drafts in the winter. We have a ‘smart’ thermostat that we can program to change the temperature at different times during the day; since we are retired, that is usually letting it cool down a bit at night while we are sleeping.

In general, modern heating systems and houses, make it easier to feel warm in the winter. I wonder sometimes if that changes the early years of children’s lives. For example – a baby born in December would be learning to walk a year later. Prior to central heating, that would mean more clothes to get in the way during that process than a child born in July would have as they learned to walk. Did mothers of winter babies keep them close to their own bodies to make sure they were warm (i.e. did winter babies get held more in their very early lives)? Central heating might have made early childhood development more consistent because it took away much of the seasonal variation experience for babies!

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.

Four key questions on the new wave of anti-obesity drugs – Several of the drugs were originally developed to treat type 2 diabetes but now are popular weight loss drugs.

Sweet smell of success: Simple fragrance method produces major memory boost – A study done by the University of California, Irvine on older adults…participants reaped a 226% increase in cognitive capacity compared to the control group. A product based on their study and designed for people to use at home is expected to come onto the market this fall.

How the US is fighting back against deadly floods – Identifying flood plains…not building back in them after a flood.

Old-Growth Trees, Some Dating To 17th Century, Protected at New River Gorge – The Burnwood Loop – where I want to hike first in the New River Gorge National Park and Preserve!

Does Cooking with Gas Stoves Hurt Indoor Air Quality? – Yes…but how much is the better question. 12.7% of current childhood asthma in the United States is attributable to gas stove use.

A quick look inside a human being – Magnetic Particle Imaging (MPI)…using a portable scanner to visualize dynamic processes in the human body such a blood flow.

Why it's so important to figure out when a vital Atlantic Ocean current might collapse - Humans are changing the fundamental processes of the Earth faster than we can understand them. The collapse of the current would have effects around the planet: temperatures in Europe would fall, heat in the tropics would rise, rainfall would decrease across the Sahel in Africa, the summer monsoon would weaken across Asia, and sea levels would rise even faster in the eastern US.

New Thermal Activity on Geyser Hill in Yellowstone National Park – Short video from the Yellowstone Volcano Observatory.

‘Perfectly Preserved’ Glassware Recovered From 2,000-Year-Old Shipwreck – The shipwreck was located 1,148 feet below the surface in waters between Italy and France. Two remotely operated vehicles (ROV) were used to scan the site and recover artifacts.

Short bursts of daily activity linked to reduced cancer risk - A total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers (i.e. cancers associated with physical activity such as liver, lung, kidney, gastric cardia (a type of stomach cancer), endometrial, myeloid leukemia, myeloma, colorectal, head and neck, bladder, breast and esophageal adenocarcinoma (cancer of the esophagus) by up to 32 percent.

Utilities

My husband made the arrangement to transition of utilities from the previous owner to us in our Missouri house. The water, sewer, electric, gas and trash/recycle were all with the city…easier than in locales where each one is separate.  

We thought that maybe the internet/cable connection would take longer, but we got an appointment for the day after closing! What a relief to have that taken care of before I made the whirlwind trip back to Maryland!

It seems like the process was easier than when we moved to our Maryland house 25+ years ago…a positive experience.

Now to wait a month and see how we do on electric usage with the air conditioner keeping the house comfortable during the summer heat. The gas usage during the summer is only for hot water so should be at the lowest for the year.

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.

Beware the joro spider. Scientists say the giant, but harmless, arachnid is spreading – A native of Japan…it has been in the southeastern US for the past decade. It may be poised to continue up the eastern seaboard. Fortunately, they are not lethal to humans and the eat mosquitos/stink bugs.

Top 25 birds of the week: Seedeaters! – We see some of these at our birdfeeders!  

Cognitive Bias Codex, 2016 – A graphic I had not seen before….very thought provoking.

Revealing an Ice Age Route of Indigenous Peoples – Vancouver Island…analyzing lake sediments. One of them, Topknot Lake, was evidently never covered by glaciers so the sediment was very deep.

Hidden dangers lurking in your kitchen - A little history…and one that is relevant to my house hunting: I don’t want to buy a house with gas stove…if I do, it will be replaced with an electric ASAP.

Common house plants can improve air quality indoors – Modern homes are more airtight than ever…and indoor air quality can become a problem. Good to know that plants can help – and they are generally aesthetically pleasing too.

Why soil is a surprisingly noisy place – Wow! A whole new way of studying soil…listening to it.

Gas flares tied to premature deaths – A study done by Rice University environmental engineers with data from North Dakota and Texas. There are currently no limits to flaring, unfortunately. Why can’t we use the gas productively? It bothers me when we hear that we need more fossil fuels to observe the way the industry still is so wasteful and polluting.

Dying for makeup: Lead cosmetics poisoned 18th century European socialites in search of whiter skin – I had heard of lead makeup before…but never is this detail.

Top 25 birds of the week: forest birds – The only one of these that appears in the forest behind our house in Maryland is the Tufted Titmouse.

Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections – The labelling on foods fortified with Vitamin D does not say which type is used – hopefully it is D3. The supplemental Vitamin D I take is definitely D3.

The Prairie Ecologist – Photos of the Week – February 26, 2022 – Winter photography….it’s about over for us. Daffodils are up!

What is the best age to learn to read? – There is more variability that I realized…generally between 4 and 7. There is growing consensus that there is no reason to rush it. Learning language is key and often older children learn to read faster because their spoken language skills are greater.

Effects of noise on marine life – The study was focused on turtles and observed noise-induced hearing loss (sometimes temporarily) which hampers their ability to detect predators, communication, navigation, etc.

Rash-causing moths are spreading in Maine because of climate change – Browntail moths (native to Europe). I thought when I saw the headline that it might be about the saddleback caterpillar which is native to North America and has stinging spines that cause a painful rash. We had a specimen in the Brookside Gardens Wings of Fancy exhibit back in July/August 2018.

Study of algae in Acadia National Park lakes shows recovery from acidification – A success story…the Clean Air Act Amendments enacted in the 1900s are making a difference!

Roman noblewoman’s tomb reveals secrets of ancient concrete resilience – This research has application to the future: transitioning to Roman-like concrete could reduce the energy emissions of concrete production and installation by 85%...and improve the longevity of concrete by orders of magnitude.

How to bring more clean energy into our homes – It’s hard to know what to do that will make the most difference in decarbonization. Electrification is good…as long as the energy used to create the electricity is renewable. This article is explaining one attempt to make it simpler…but it doesn’t seem like it goes far enough.

Does the world need more sharks? – Evidently when sharks decline, herbivores increase and seagrass declines….resulting in less carbon sequestration in sea vegetation. So – more sharks would improve our climate change situation!

The incredible opportunity of community schoolyards – Transforming paved public schoolyard by adding trees, gardens and stormwater management systems and opening them to the public after hours….what’s not to like? It is good for children and the community…and reduces the heat island around the school.

Recycled concrete and CO2 from the air are made into a new building material – Potentially another way to reduce the energy and emissions to produce concrete…but there is still a challenge to make it strong enough for all the current places we use concrete - to make calcium carbonate concrete viable in the future.

10 Writing Awards for Cool Green Science – Some of the 10 have probably be in my gleanings before…but they are worth looking at again.

We need to talk about your gas stove, your health and climate change – 35 years ago, I thought gas stoves were wonderful….but I haven’t had one since 1986, and I won’t buy a house in the future with one (or I will replace it immediately). My current house does have a gas hot water heater and furnace…but I plan to jettison those too. And I don’t want a gas fireplace either!

Clean air matters for a healthy brain – I check the Air Quality Index on Weather.com and there are too many days that the PMI2.5 level is ‘yellow’ where I live now in Maryland. I try to not spend a lot of time outdoors on those days.  It’s another something to think about when/if I move out of the area.

The American Bumblebee Has Vanished From Eight States – The 8 states are: Maine, Rhode Island, New Hampshire, Vermont, Idaho, North Dakota, Wyoming, and Oregon. That doesn’t mean other places are much better. They have declined 99% in New York; 50% in the Midwest and Southeast.

Large scale solar parks cool surrounding land – The observation is interesting. I wonder if the solar parks that I’ve seen frequently around airports in the US are large enough to make up for the heat island effect of all the concrete and asphalt surfaces of the airports.
