Microplastics Are Even In Ocean Waves and Air
We can not get away from microplastics - the teeny, tiny plastic particles that are a result of plastics breaking up over time. They are everywhere, including the air over polar regions and in the air spewed out in the sea spray from waves.
Researchers sampled and analyzed air off the Norwegian coast up to the Arctic region. They found that all air samples contained microplastics. The plastic particles they found included polyester particles (from textiles), polystyrene, polypropylene, polyurethane, and tire wear particles (from driving and braking). Sources of the plastic particles came from both land (e.g., textiles, tire particles) and sea (e.g., boat paint).
Microplastics are plastic particles less than 5 mm (0.20 in) in length. Rain, water (e.g., seas, rivers), wind and air transport the plastic particles throughout the world. This microplastic pollution is of concern to all of us because we are breathing them in, and they are in the products we use (e.g., toothpaste), foods we eat, and the beverages we drink, including bottled water.
The big questions: What are the microplastic particles doing to us and wildlife? Are they getting into our organs? Are they causing chronic inflammation or other problems? Hint: Yes and yes, according to research. Even our lungs and blood.
From Science Daily: Oceans release microplastics into the atmosphere
Tiny plastic particles can be found in the sea air even far from coasts, according to a study recently published in the journal Nature Communications. The microplastics come from partly unexpected sources. ...continue reading "Microplastics Are Even In Ocean Waves and Air"
Scientists Report That July Was the Hottest Month On Record
We knew it was hot in July. Record breaking hot. Europe's climate monitoring organization (Copernicus Climate Change Service) announced this week that July was the Earth's hottest month on record. By a wide margin.
The global average temperature for July was 62.51 degrees F (16.95 degrees C). The record for hottest month prior to this was July 2019. According to experts, July was the hottest month in about 120,000 years!
The global sea surface temperatures for July also broke historic records. The sea ice in the Antarctic broke the July record for below average sea ice. Do you see a pattern? Uh - oh. The world is really warming up...
According to a Climate Central report, more than 6.5 billion people (or more than 81% of people on Earth) experienced hotter temperatures in July than they would have without human-caused climate change.
Excerpts from World Meteorological Organization: July 2023 is set to be the hottest month on record
According to ERA5 data from the EU-funded Copernicus Climate Change Service (C3S), the first three weeks of July have been the warmest three-week period on record and the month is on track to be the hottest July and the hottest month on record. These temperatures have been related to heatwaves in large parts of North America, Asia and Europe, which along with wildfires in countries including Canada and Greece, have had major impacts on people’s health, the environment and economies. ...continue reading "Scientists Report That July Was the Hottest Month On Record"
Hammerhead Flatworms Are Creepy and Spreading Up the East Coast
Another creepy creature is making its way up the eastern seaboard. Invasive hammerhead worms that are about 22 inches long and contain a neurotoxin (poison) are spreading up the southeastern coast (e.g., Florida, Georgia) north to Washington DC, Virginia, Maryland, Pennsylvania, NJ and elsewhere. Yikes!
The flatworms (Bipalium) originally came from Asia. They contain tetrodoxin (TTX), which causes paralysis of the muscle tissue. It's the same toxin found in puffer fish! But what makes the worms ultra-creepy is that if one gets broken up into mutiple pieces, each piece can regenerate to become a fully functioning worm!
Biologists say they are not a danger to humans unless handled (can cause skin irritation) or eaten (many of them). They can be killed by pouring some salt on them, and then dispose by placing into a plastic bag. Don't handle with bare hands - use a stick or wear gloves.

We’re On Track For Each Summer to Be Hotter Than Ever
This past Monday (July 3) the average temperature on Earth was the hottest day ever recorded. But then...Tuesday broke Monday's records for hottest day for Earth. It hit 62.92 degrees Fahrenheit (17.18 degrees Celsius)
Welcome to the new normal. In fact, this summer could be the coolest summer of the rest of your life! Get ready for more and longer heat waves. For summer to start earlier, last longer, and be hotter.
Why is this occurring? Climate change. All the scientific predictions are coming true. And yet the US government, politicians, big business, and all of us are refusing to take real action. We need a huge reduction of fossil fuel emissions and new technologies to pull carbon dioxide out of the air to stop extreme climate changes from occurring.
Several good articles about what is going on: 1) From The Guardian: Tuesday was world’s hottest day on record – breaking Monday’s record
World temperature records have been broken for a second day in a row, data suggests, as experts issued a warning that this year’s warmest days are still to come – and with them the warmest days ever recorded.
2) From the Washington Post: This July 4 was hot. Earth’s hottest day on record, in fact.
... some scientists believe July 4 may have been one of the hottest days on Earth in about 125,000 years, due to a dangerous combination of climate change causing global temperatures to soar, the return of the El Niño pattern and the start of summer in the Northern Hemisphere. ...continue reading "We’re On Track For Each Summer to Be Hotter Than Ever"
Genetic Risk Factors For Dupuytren’s Contracture Are Inherited From Neanderthals
It turns out that many people of northern European descent have inherited some Neanderthal genes. A study found that these are contributing to a higher risk for Dupuytren's contracture (also called Dupuytren's disease). One study estimated that about 30% of Norwegian males over the age of 60 have Dupuytren's disease, but studies find that it is rare in African populations.
The researchers of the study looking at Dupuytren's disease noted that the average Neanderthal ancestry among Europeans is about 2%. [Note: Neanderthals are also referred to as Neandertals.]
Dupuytren's disease is a gradual thickening and tightening of tissue under the skin in the hand, which eventually can cause one or more fingers to stay bent toward the palm. It usually occurs in men over the age of 60.
Neanderthals and Denisovans (referred to as “archaic humans”) are now extinct. They lived in Western (Neanderthals) and Eastern Eurasia (Denisovans) until approximately ∼42,000 years ago. There was interbreeding (sex) with modern humans (Homo sapiens), which is how some of their genes have been passed down through the years.
From Science Daily: The Viking disease can be due to gene variants inherited from Neanderthals
Many men in northern Europe over the age of 60 suffer from the so-called Viking disease, which means that the fingers lock in a bent position. Now researchers at Karolinska Institutet, together with colleagues, have used data from over 7,000 affected individuals to look for genetic risk factors for the disease. The findings, which have been published in Molecular Biology and Evolution, show that three of the strongest risk factors are inherited from Neanderthals. ...continue reading "Genetic Risk Factors For Dupuytren’s Contracture Are Inherited From Neanderthals"
Enjoy the Day!
Today is the summer solstice. It's the first day of summer in the Northern Hemisphere. Enjoy!
The summer solstice occurs when one of the Earth's poles has its maximum tilt towards the sun. It's the day with the longest period of daylight and shortest night of the year.
After today, the length of daylight in the Northern Hemisphere will start shortening until the winter solstice in December.
Great Resource For Learning About Your Air Quality
Meteorologists are predicting that we (in the US and Canada) will be experiencing more hazardous air quality days in the coming months and years due to wildfire smoke. An excellent resource for monitoring the air quality where you live is AirNow.gov. It has both current air quality and forecasts.
The NY Times currently has interactive air quality maps, which are tracking the wildfires from Canada.
Smoke is air pollution, whether it's from wildfires, cigarettes, or vehicles. It's not just our lungs and internal organs that suffer from smoke with particles smaller than 2.5 microns. (For comparison: A human hair is at least about 20 microns in diameter.) The particles travel from the lungs through our bloodstream to the organs. But our skin also suffers. It causes flares of inflammatory skin diseases such as eczema, atopic dermatitis, and psoriasis, and increases wrinkles and age spots.
Air pollution is dangerous to everyone!
Some health effects of air pollution: Harm to the lung and airways, damage to most organ systems of the body, lung cancer, COPD deaths, heart disease deaths, stroke deaths, bladder cancer, childhood leukemia, poorer lung development in children, lung impairment in adults, reduced cognitive function, increased risk of dementia, diabetes, effects on immune system, allergic rhinitis, structural changes in the brain, inflammation, and with high levels of smaller than 2.5 μm particles can have delayed psychomotor development and lower child intelligence. And the list goes on!
Do go and check out AirNow.gov and all the links on the site, including an interactive fire and smoke map. Stay indoors (as much as possible) with the windows shut on "unhealthy, very unhealthy, or hazardous" air quality days. Consider wearing masks outdoors and using an air purifier indoors on those days.
Serious Problems With Spray Foam Insulation Used In Homes
For years I've been concerned about spray foam insulation that is blown into attics and walls. Yes, it is promoted on popular home renovation shows. But what is not discussed is that the chemicals in the foam would be outgassing for years and the occupants of the home would be breathing it in.
Finally, I'm starting to see concerns raised by others - not just harmful health effects from the chemicals, including flame retardants, but also harms to the house itself. It turns out the industry is hiding the harms.... (why doesn't that surprise me?)
Excerpts from an article by Alden Wicker from VTDigger (an independent Vermont news website that publishes watchdog reports): 'I wanted to cry': Devastating risks of spray foam insulation hidden from Vermont homeowners
Londonderry contractor Abe Crossman was keeping busy with small projects at his family’s home in June 2020 during the newly arrived coronavirus pandemic. He was working outside when he noticed that the paint was peeling off the trim at the peak of the gable end of his roof.
With 25 years of building experience, he knew that peeling paint indicated the presence of moisture. But the location was odd — that trim underneath the overhang should stay dry. So he grabbed a ladder and a pry bar to take a closer look.
His stomach dropped as he sank the pry bar into the soft wood sheathing underneath the trim and peeled away the vinyl siding down to four feet below the roof line. What had been wood disintegrated into dust in front of his eyes, he later recalled, leaving behind nothing but spray polyurethane foam insulation. ...continue reading "Serious Problems With Spray Foam Insulation Used In Homes"
Record High Temperatures Predicted For Next Five Years
Are you ready for the world getting hotter over the next 5 years? And along the way setting record highs?
The World Meteorological Organization (WMO) predicts that the next 5 years are likely to have temperatures soaring to record highs. The causes are climate change (from heat-trapping greenhouse gasses) plus a naturally occurring El Nino (which is expected to start this summer).
Thus WMO Secretary-General Professor Petteri Taalas warns us:
“A warming El Niño is expected to develop in the coming months and this will combine with human-induced climate change to push global temperatures into uncharted territory,” he said. “This will have far-reaching repercussions for health, food security, water management and the environment. We need to be prepared.”
Why isn't everyone in the US government (including Senate and House of Representatives) taking serious steps about climate change? Our climate is changing!
From the World Meteorological Organization: Global temperatures set to reach new records in next five years
Global temperatures are likely to surge to record levels in the next five years, fuelled by heat-trapping greenhouse gases and a naturally occurring El Niño event, according to a new update issued by the World Meteorological Organization (WMO). ...continue reading "Record High Temperatures Predicted For Next Five Years"
