How Extreme Heat Kills, Sickens, Strains and Ages Us
Kenney has looked at how heat stress affects a range of people in intense environments: football players, soldiers in protective suits, distance runners in the Sahara.Of late, however, his research has focused on a more mundane subject: ordinary people. Doing everyday things. As climate change broils the planet.
Already, the link between greenhouse-gas emissions and sweltering temperatures is so clear that some researchers say there may soon no longer be any point trying to determine whether today’s most extreme heat waves could have happened two centuries ago, before humans started warming the planet. None of them could have.And if global warming is not slowed, the hottest heat wave many people have ever experienced will simply be their new summertime norm, said Matthew Huber, a climate scientist at Purdue University. “It’s not going to be something you can escape.”...Heat is climate change at its most devastatingly intimate, ravaging not just landscapes and ecosystems and infrastructure, but the depths of individual human bodies.Heat’s victims often die alone, in their own homes. Apart from heatstroke, it can cause cardiovascular collapse and kidney failure. It damages our organs and cells, even our DNA. Its harms are multiplied in the very old and very young, and in people with high blood pressure, asthma, multiple sclerosis and other conditions.When the mercury is high, we are not as effective at work. Our thinking and motor functions are impaired. Excessive heat is also associated with greater crime, anxiety, depression and suicide....Venugopal gets frustrated when asked, about her research on Indian workers, “India is a hot country, so what’s the big deal?”Nobody asks what the big deal is about having a fever, but heatstroke puts the body in a similar state.
Heat Stress Kills Estimated 10,000 Head of Kansas Feedlot Cattle...What is known is that leading up to these heartbreaking losses, temperatures in the area were over 100 degrees Fahrenheit, there was humidity, and there was little to no wind to help cool the animals. Temperature readings reported for Ulysses began to exceed the 100-degree mark on June 11. By June 13, the high temperature was reported at 104 degrees, with humidity levels ranging from 18% to 35%....Large losses in feedlots due to heat stress seem to start every year around June, said veterinarian A.J. Tarpoff, who works with Kansas State University Extension. He explained that when there is a "perfect storm" of too much heat and no opportunity for nighttime cooling, cattle can accumulate heat and die from the stress. It's a situation, he added, that can hit both feedlot and grazing animals.
On Tuesday, Miles Teller swung by Late Night With Seth Meyers and revealed that he got terribly sick while shooting Top Gun: Maverick. The actor was doing some aerial exercises in a jet and upon landing, he realized something was very wrong“So we landed, I'm just like, ‘I'm not feeling too good,’ Teller explained. “And I was really hot, and I just started itching like crazy. So I get out of the jet, and I'm just covered in hives, like, head to toe.”Teller went to the doctor and had a blood analysis performed. He then spent the evening in an oatmeal bath, trying to reduce the hives on his skin. The following day, he received some interesting news from his doctor.“My bloodwork comes back, and I have flame-retardant, pesticides, and jet fuel in my blood,” Teller said.
Teller was born in Downingtown, Pennsylvania.[5] His mother, Merry, is a real estate agent, and his father, Michael, is a nuclear power plant engineer.[6][7] He has two older sisters, Erin and Dana.[6][8] His paternal grandfather was of Russian Jewish descent,
Scientists searching for the causes of falling sperm counts are getting a clearer picture of the role played by chemical pollutants - and it’s not a pretty one.A study of urine samples from nearly 100 male volunteers has uncovered "alarming" levels of endocrine disruptors known to reduce human fertility.Cocktails of chemicals such as bisphenols and dioxins, which are believed to interfere with hormones and affect sperm quality, were present at levels up to 100 times those considered safe.The median exposure to these chemicals was 17 times the levels deemed acceptable."Our mixture risk assessment of chemicals which affect male reproductive health reveals alarming exceedances of acceptable combined exposures," wrote the authors of the study, published on Thursday in the journal Environment International.
Since publication of this footage, shipping traffic has been slowed to proper speeds and monitored by the US & Canadian Coast Guard to ensure all vesels maintain compliance.
Sources and transportation pathwaysPFC gases do not exist naturally in the atmosphere but are produced synthetically. The most important transportation pathway is by emissions to air from industrial processes. In Sweden, emissions are reported from larger operations within the sector production and processing of metals (primary aluminium production).Effects on environment and healthPFCs are potent greenhouse gases that contribute to the increased greenhouse gas effect3. The increased greenhouse gas effect results in an increase of the average temperature on earth, which for example leads to climate change and rising of the sea level4,5. Some PFCs can also cause harmful long-term effects on aquatic organisams6.Health effects vary somewhat between different perfluorocarbons. Some PFCs may cause damages to liver and kidneys7, whereas others may irritate the skin and cause severe eye irritation8,9.International agreements and regulationsPerfluorocarbons are regulated by the UN Framework Convention on Climate Change (UNFCCC) as well as by the EU MMR (525/2013/EU), the EU ETS (2003/87/EU) and the EU F-gas regulation (517/2014/EU). The UN Protocol on PRTRs and the EU E-PRTR regulation regulate how data on perfluorocarbons is made available.
One of the most common halons has the chemical formula CBrClF2, denoted as H-1211 in an industry-devised shorthand. The compounds live long enough in the atmosphere (eleven years in the case of H-1211) to reach the stratosphere, an upper region of the atmosphere located between fifteen and fifty kilometers above the earth's surface, where the sun's more intense ultraviolet (UV) radiation breaks down the molecule and releases chemically active bromine and chlorine atoms. These free atoms enter into cycles of chemical reactions that destroy ozone.
How is Halon 1301 Produced?Although the manufacturing process of Halon 1301 is not disclosed, it’s chemical properties are well-known. The chemical name for Halon 1301 is Bromotrifluoromethane. Bromotrifluoromethane is an organic halide which is a precursor to trifluoromethyltrimethylsilane, a popular reagent used in the organic synthesis. The chemical formula of Bromotrifluoromethane is CBrF3. As a fire extinguishing agent, it does not produce the characteristic white cloud similar to CO2. Because of this, it is not ideal to be used for fighting large fires.How is Halon 1211 Produced?The chemical name for Halon 1211 is Bromochlorodifluoromethane. It is a haloalkane that is used for fire suppression, particularly for costly equipment. The chemical formula of Bromochlorodifluoromethane is CF2ClBr. Bromochlorodifluoromethane is an excellent fire extinguishing agent with low pressure, low toxicity, liquefied gas. It is very effective for extinguishing all common types of fires. Bromochlorodifluoromethane is commercially synthesized from chloroform via a two-step process. Similar to Halon 1301, the production process of Halon 1211 is not disclosed.How is FM-200 Produced?The exact method of manufacturing FM-200 is not disclosed, but its chemical properties are well-known. The chemical formula of FM-200 is C3HF7. The FM represents the chemical called Heptafluoropropane which is a colorless and odorless gas. The FM-200 fire suppression system is made up of elements such as hydrogen, fluorine, and carbon. Heat absorption is the primary mechanism through which this agent gets rid of fire. It is considered as the halocarbon agent which is safe even when used in the presence of people.For storage, FM-200 is liquified under pressure. This compound of carbon, hydrogen, and fluorine is electrically non-conductive. The fire suppression agent used in FM-200 fire extinguishers is an acceptable replacement for Halon because it has no ozone depleting potential.
A bear scrounging for food got stuck in someone’s parked car and died when temperatures inside reached an estimated 140 degrees, according to the Tennessee Wildlife Resources Agency.It happened Wednesday, June 22, outside a rental cabin in Sevierville, a tourist destination 15 miles north of Great Smoky Mountains National Park.“The car’s owner left the cabin in a different vehicle around 10 am and found the bear dead inside upon returning at 6:45 pm.,” the agency said in a news release.“It appears that the bear got inside the car by using its teeth or paws to open the unlocked door and was trapped inside after the door shut behind it. We believe that heat likely killed the bear as outside temperatures exceeded 95 degrees yesterday meaning the vehicle’s interior possibly reached over 140 degrees.”
In today's documentary, we're covering an unbelievable case of chimpanzee ownership gone horribly wrong: the true story of Travis the Chimp. Travis the Chimp had been kept as a beloved pet by his owners Sandra and Jerry until the fateful day of February 16th, 2009, when Sandra's world would be turned upside down. The events of that dreadful day were documented in a haunting 911 call, where you can hear Sandy begging the police to come to her home. Travis had snapped, mauling her friend and causing irreversible damage. The reasons why Travis went berserk remain a complete mystery, but one thing is for certain: this video shows why you should NEVER own an exotic pet. Although this true story is truly haunting, it's also educational, as it shows why you should NEVER take a wild animal out of its habitat and try to treat it like a domesticated animal. Join us for a chilling storytime covering the case of Travis the Chimp.
Ninety percent of wet wipes on the market are produced from nonwoven fabrics made of polyester or polypropylene.[4]The material is moistened with water or other liquids (e.g., isopropyl alcohol) depending on the applications. The material may be treated with softeners, lotions, or perfume to adjust the tactile and olfactory properties. Preservatives such as methylisothiazolinone are used to prevent bacterial or fungal growth in the package. The finished wet wipes are folded and put in pocket size package or a box dispenser.
A "wet wipe island" the size of two tennis courts has formed in the Thames, causing the river as it flows through London to change course, according to The Times of London....Most wet wipes are made with plastic, which does not break down when flushed, according to environmental charity Thames21.Furthermore, they can break down into microplastic and damage aquatic life and the Thames' ecosystem, the charity said....Last year, volunteers for the charity collected more than 27,000 wipes over two days at a different site next to Battersea Bridge.Wet wipes also make up nearly 90% of the materials contained in "fatbergs," which are masses of solid waste made of grease and fat that can block sewers.
‘Disturbing’: weedkiller ingredient tied to cancer found in 80% of US urine samples...The report by a unit of the Centers for Disease Control and Prevention (CDC) found that out of 2,310 urine samples, taken from a group of Americans intended to be representative of the US population, 1,885 were laced with detectable traces of glyphosate. This is the active ingredient in herbicides sold around the world, including the widely used Roundup brand. Almost a third of the participants were children ranging from six to 18.
The first modern herbicide, 2,4-D, was first discovered and synthesized by W. G. Templeman at Imperial Chemical Industries....Independently, a team under Juda Hirsch Quastel, working at the Rothamsted Experimental Station made the same discovery. Quastel was tasked by the Agricultural Research Council (ARC) to discover methods for improving crop yield. By analyzing soil as a dynamic system, rather than an inert substance, he was able to apply techniques such as perfusion. Quastel was able to quantify the influence of various plant hormones, inhibitors and other chemicals on the activity of microorganisms in the soil and assess their direct impact on plant growth. While the full work of the unit remained secret, certain discoveries were developed for commercial use after the war, including the 2,4-D compound.[8]
Dr. Nikos Christidis, a climate attribution scientist, said that 104-degree summers in the UK are now up to 10 times likelier than they would be “under a natural climate unaffected by human influence.”
