Climate change poses significant challenges to cattle farming, a sector vital to global food security. Among the most pressing concerns is the increasing frequency and intensity of droughts. Reduced rainfall diminishes pasture quality and availability, limiting feed for livestock and increasing water scarcity. This can lead to decreased animal growth rates, reduced milk production, and increased mortality rates. Moreover, prolonged droughts can contribute to desertification, shrinking available grazing land and forcing farmers to adopt costly alternative feeding strategies.
Beyond drought, other climate-related impacts include heat stress, which can significantly impact animal health and productivity. Rising temperatures can exacerbate heat stress, leading to decreased feed intake, reduced fertility, and increased mortality in livestock. Furthermore, extreme weather events, such as heavy rainfall and flooding, can cause infrastructure damage, contaminate water sources, and lead to the loss of livestock.
The cattle farming sector itself contributes to climate change through greenhouse gas emissions, primarily methane produced during animal digestion and nitrous oxide from manure management. Deforestation for pasture expansion also releases significant amounts of carbon dioxide.
To address these challenges, a multi-pronged approach is crucial.
• Genetic selection: Breeding programs focused on developing drought-resistant livestock breeds are vital. and heat-tolerant
• Sustainable feeding strategies: Implementing precision feeding techniques, improving feed efficiency, and exploring alternative drought-resistant forage livestock resilience. feed sources, varieties, such as can enhance
• Integrated farming systems: Integrating crop and livestock production, such as through agroforestry systems, can improve soil health, enhance water retention, and reduce greenhouse gas emissions.
• Technological innovations: Utilizing technologies such as precision livestock farming, remote sensing for pasture monitoring, and renewable energy sources can improve resource efficiency and redu
Furthermore, strong policy support, including incentives for sustainable farming practices, investments in research and development, and improved access to climate information services, are essential for the long-term sustainability of the cattle farming sector.
Addressing the challenges posed by climate change requires a collaborative effort involving farmers, researchers, policymakers, and consumers. By embracing innovative solutions, prioritizing sustainable practices, and fostering a collective understanding of the importance of climate-resilient livestock production, we can ensure a future when this vital sector continues to thrive while minimizing its environmental impact.

PUCKER UP I'm a dermatologist - you've been using lip balm all wrong - here's why your pout is still chapped
(1º§)YOU might be reaching for your lip balm more and more through these winter months. But are your lips still sore and chapped, no matter how much of the stuff you slather on? According to dermatology experts, the type of balm you put on your pout might be more important than the amount.
(2º§)Dr. Mona Gohara, an associate clinical professor of dermatology at the Yale School of Medicine, and Dr. Brendan Camp, a dermatologist at MDCS Dermatology in New York, told TODAY why some lip balms could do more harm than good.
(3º§)To start with, they discussed why your lips might be chapped in the first place. The cold weather can wreak havoc on them as the skin is very thin, so they're more likely to dry out, Dr Gohara said. Meanwhile, Dr Camp noted that the delicate skin of your pout can easily be irritated by ingredients in skincare or food, yeast or bacteria, and even enzymes in saliva.
(4º§)You might also not be giving them enough love: lot's of people forget about their lips when they're moisturising their face. But if your lips are dry and chapped not long after you apply your balm, you just might be using the wrong kind.
(5º§)Four things to avoid in a lip balm:
1.Tingly balms
2. Fragrances
3. Flavouring agents
4. Dyes
(6º§)Dr Camp said these might cause allergic contact dermatitis, a type of eczema triggered by contact with a particular substance. And if your lips are dry, cracked, red, scaly and itchy, you might have developed a sensitivity to an ingredient in your lip balm, he added. Moral of the story, check your lip balm ingredients.
(7º§)Since you're doing that, there are a few ingredients that will help hydrate your pout. Dr Camp said you want to look for ingredients that will help trap water in the skin while keeping it moisturized for a long period of time. "Ingredients like beeswax, olive oil, castor oil, coconut oil, and shea butter are often used for this purpose," he said.
(8º§)You should also be wearing a salve with SPF to protect your lips from the sun. Meanwhile, Dr Gohara said that your ideal balm will have a combination of humectants (like hyaluronic acid and glycerin), which draw moisture into the skin, and occlusives (such as shea butter and mineral oil), which lock moisture in.
(9º§)The NHS recommended you use one containing petroleum jelly or beeswax. It said: "Try a few different lip balms if one is not working for you - some people may be sensitive to some fragrances, dyes or cosmetic ingredients."
(10º§)As long as you're using the right type of balm, Dr Gohara said you can apply it multiple times a day. According to Dr Camp, it's best to put on lip balm once in the morning and once before bed. There are other ways of preventing dry lips too.
(11º§)Lisa Borg, skin specialist and nutritionist at the Pulse Light Clinc, said the best thing you can do is drink plenty of fluids throughout the day. Preferably quality water as opposed to dehydrating coffee and fizzy drinks, she noted.
(12º§)Lisa also recommended eating foods that simulate saliva production, such as apples, cucumbers, tomatoes, courgettes, watermelon, lemons, and crunchy fibrous vegetables like carrots and celery. Meanwhile, the NHS said you should wash your hands before applying lip balm and cover your lips with a scarf when you're outside in cold weather. If you're outdoors, use a balm with SPF 15 or more every two hours, it added.
(13º§)Common causes of dry lips: cold weather, dry air or wind; damage from the sun; dehydration; a lip injury; allergies; and lack of vitamins and minerals. If you have sore or dry lips, you should avoid: picking or biting any flaky skin on your lips - this can slow down healing; licking dry or cracked lips - this can make them sore; and sharing lip balms with other people - this can spread germs.

Pollution
Thick black smoke curling out of smokestacks, horrible-tasting chemicals in your drinking water, pesticides in your food - these are examples of pollution. Pollution is any contamination of the environment which causes harm to the environment or the inhabitants of the environment. There are many kinds of pollution, and there are many pollutants. Some obvious kinds of pollution are pollution of the air, soil, and water. Some less obvious, or less salient kinds of pollution are radioactive, noise, light pollution, and green-house gasses.
Air pollution can be caused by particles, liquids, or gases that make the air harmful to breathe. There are two main types of air pollution: primary and secondary. Primary pollutants enter the air directly, like smoke from factories and car exhaust. Secondary pollutants are chemicals that mix together to pollute the air, like mixtures of emissions, or waste output, from vehicles and factory smoke that change to form more dangerous pollutants in the air and sunlight.
Soil pollution can be caused by pesticides, leakage..........................chemical tanks, oil spills, and other chemicals..........................get into the soil by dumping or accidental contamination. Soil pollution can also cause water pollution.............................underground water becomes contaminated by coming.............................contact with the polluted soil.
Water pollution can be caused by waste products, sewage, oil spills, and litter in streams, rivers, lakes, and oceans. Some scientists believe that water pollution is the largest cause of death and disease in the world, causing about 14,000 deaths in the world each day.
Radioactive pollution can be caused by leaks or spills of radioactive materials. These materials can come from medical sources, nuclear power plants, or laboratories which handle radioactive materials. Air, soil, and water can be polluted by radioactivity. It can cause damage to animals, both internally and externally, by eating, drinking, or touching it. It can cause birth defects and genetic problems. It can cause certain cancers and other deadly diseases.
Noise pollution can be caused by vehicle, aircraft, and industrial noise. It can also be caused by military or experimental sonar. Noise has health effects on people and animals. In people, it can cause high blood pressure, heart problems, sleep disturbances, and hearing problems. In animals, it can cause communication, reproductive, and navigation problems – they have difficulty finding their direction. Sonar has even caused whales to beach themselves because they respond to the sonar as if it were another whale.
Light pollution can be caused by advertising signs, stadium and city lighting, and other artificial lighting (like the light caused by night traffic). Artificial lighting has health effects on humans and animals. In people, it can cause high blood pressure and affect sleeping and waking rhythms and immunity. It might be a factor in some cancers, such as breast cancer. In animals, it can affect sleeping and waking rhythms, navigation, and reproduction.
In addition, greenhouse gases have caused a warming effect on the earth’s climate. The greenhouse gases are water vapor, carbon dioxide, methane, and ozone. They are naturally–occurring gases in the atmosphere, but human activity has increased their concentration in the atmosphere. For example, the levels of carbon dioxide (CO2) in the atmosphere have risen due to the burning of fossil fuels. The effect is a rise in global temperatures. The higher temperatures cause the melting of glaciers, a rise in the water level of oceans, and the disruption of both land and marine life, including that of humans. Although carbon dioxide is necessary for plants to survive, it is also considered to be a kind of pollution because high levels of carbon dioxide have caused the oceans to become more acidic.
It is not possible for anyone to predict the exact timing and effects of global pollution and global climate change brought about by pollution. There is general agreement by scientists that the global climate will continue to change, that the intensity of weather effects will continue to increase, and that some species of animals will become extinct. There is also general agreement, or consensus, that humans need to take steps to reduce emissions of waste products and greenhouse gases into the atmosphere, make adaptations to the changes that are occurring, and figure out ways of reversing the trends of pollution and global warming.

The enduring joy of Golden Girls: a wildly sassy sitcom that will always cheer you up
A comedic masterclass with the best sitcom theme song of all time, Golden Girls pulled back the curtains on ageing and dealt with big-ticket issues.
A zinger-infused maelstrom of shoulder pads, pastels and perms. Rattan furniture, DayGlo linen and Formica. There’s such a distinctive look, feel and vibe to The Golden Girls, the iconic sitcom that ran from 1985 to 1992, scooping up 68 Emmy nominations and 11 wins in the process. The brainchild of producer Susan Harris, the show spawned several acclaimed spinoffs and became an enduring work of high camp in the process.
The premise? Three older women decide to live together: the stern, witty ex-teacher Dorothy Zbornak (Bea Arthur), the sweet but fantastically dense Rose Nylund (Betty White) and southern hornbag Blanche Devereaux (Rue McClanahan). At first it’s a matter of convenience, but before long, they become fast friends. During the pilot they’re joined by a fourth: Dorothy’s mother Sophia Petrillo (Estelle Getty), a nitpicky little shrew whose ability to cockblock our heroines saw her gradually become the Scrappy-Doo of the house. (Don’t @ me, Goldies, you know I’m right.)
For a comedy that primarily took place within a Floridian kitchen, The Golden Girls boasted some serious talent. The four leads were all astoundingly adept at their craft.
The golden girls themselves proved that the family you make is sometimes stronger than the one you’re born with. Dorothy, Rose and Blanche feel, at times, aged out of their previous lives. Careers, spouses, the world: all seem to be pushing them away. But the girls are proof that you can – and should – forge new bonds, even if it seems like your old life is done for. That you can make a new family, even if your old one rejects you.
The Golden Girls pulled back the curtains on ageing, showing the ways in which old people can be flawed, passionate, monumentally stupid, brave – even at times, almost heroically horny. And it did so with an almost reckless willingness to be as wildly funny as it possibly could.
The show ended up doing what many sitcoms do: use antagonism as heat to push the plot forward. It takes truly hack writers to defend needless antagonism as the only source of fuel to propel a story (I’m looking at you, post-Sorkin West Wing). The last two seasons of The Golden Girls aren’t terrible, but Sophia morphs from an old lady without boundaries to an ancient sociopathic prankster. But even with this odd acceleration towards a caricatured sitcom event horizon, the show still manages to roll out the hits. The two-part finale, written by Mitch Hurwitz (the creator of Arrested Development) and starring Leslie Nielsen as Dorothy’s love interest, ranks as some of the best in the show’s history.
It also has – and I cannot stress this enough – the best sitcom theme song in the history of sitcom theme songs. In 2023, there are few things that will haul you out of whatever psychic muck you find yourself in than whacking on an episode of The Golden Girls. I promise you, once the credits roll, you’ll find yourself lying on the lanai in your mind, feeling somehow much lighter than you did before.

Vianden Castle History
(1º§) The rocky outcrop above the modern town of Vianden was first fortified in late antiquity. Excavations at the foot of the castle chapel in 1994 led to the discovery that parts of the crumbling masonry of the Late Antique tower must have existed in Merovingian times and that this square building, the only surviving structure from the period known as Late Antiquity, was incorporated into the first medieval castle.
(2º§) The first fortification was built at the beginning of Late Antiquity on the castle hill at an ancient crossroads, where a branch of the great Roman road Reims-Cologne through the Ardennes and the valley of Our led to the valley of the Sauer and through Echternach to Bitburg and Trier, at that time a thriving metropolis.
(3º§) After the Vianden fort was abandoned around 430/440 AD, the Roman Tower seems to have been sufficiently usable to remain a decisive element in the subsequent periods of castle building up to the High Middle Ages.
(4º§) The first medieval fortification was erected on the rocky spur overlooking Vianden around the year 1000. The main part of this fortification consisted of an oval ring wall. This defensive wall, meticulously reinforced with small slabs of slate, was exactly one meter wide. As with the ancient wall, this special construction technique allowed archaeologists to retrace it virtually its entire length. The old late antique moat also remained in use during this period. The entire inner surface of the fortification was leveled by filling the lower defensive wall with stones and earth. This complex also included a hall, used for administrative purposes, and a chapel, which was installed in the remains of the late antique tower.
(5º§) Vianden Castle was extensively rebuilt around 1170. The remains of the wooden scaffolding found in the new residential tower made it possible to determine the date of construction using the three-ring dating technique.
(6º§) Important architectural contributions were made, in Gothic style, between the 13th and 14th centuries by the Counts of Vianden. In 1417 the castle became a possession of the Orange-Nassau family who made changes in the Renaissance style. The castle was long in the possession of the grand-ducal family until it became state property in 1977. After this date, it was restored and shines in its former glory. Today, Vianden Castle is one of the most important architectural monuments in Europe being one of the largest and most beautiful feudal residences of the Romanesque and Gothic periods. In the entrance area there is a modern interactive visitor center.

The conceptual and epistemological grounds of literacy are being stretched as the encoded worlds we navigate increasingly interpenetrate multicultural, multilingual, and multimodal contexts. The twenty-first century finds us at a critical juncture for reevaluating English language and literacy teaching agendas. The technological revolution has facilitated and augmented human communication such that everyday interactions now essentially include digital interfaces. Language, text, and discourse norms and practices are being rapidly expanded and reinvented in response to new media and global networks. The language driving the majority of intercultural web traffic is English, which reinforces its position as a global language and adds an insidious dimension of cybercolonialism. Teachers are in crisis: domains for English language socialization now extend from known geographical and social contexts to the global panorama of the virtual world in which we, too, are learners. Information and communication technologies (ICT) have created new literacies that are required by learners of all ages if they are to fairly contend for academic and economic success. Examining the evolution of literacy into multiliteracies and considering how this epistemological shift affects ELT turned out to be a necessity. Digitally responsive, pedagogically strategic, ecologically sensitive English language and literacy teaching and learning practices should, thus, be discussed.

HVAC Contractors Need to Adapt to Repair Market
Repair or replace is a question homeowners often need to answer, and it greatly impacts an HVAC contractor's business. During COVID, the residential HVAC industry saw a replacement market boom. But in 2023 and now the beginning of 2024, there has been a shift to a repair market that HVAC contractors need to be aware of as they run their businesses.
According to numbers from the Air-Conditioning, Heating and Refrigeration Institute (AHRI), shipments of unitary air conditioners and heat pumps were down 16.7% in 2023, compared to 2022. Gas furnaces were down 23%.
"The replacement market is performing worse when you strip out new construction," said industry leader Matt Michel. "Housing starts were down around 5%, according to the St. Louis Federal Reserve, so the replacement market for unitary air conditioners and heat pumps was down in the low 20s."
Distributors are seeing similar numbers, according to the Heating, Air-conditioning, & Refrigeration Distributors International (HARDI).
"We definitely are seeing a shift here. And that shift has actually been visible for some time," said Tim Fisher, HARDI director of market intelligence.
HARDI receives data from FieldEdge on the invoice and quote trends exhibited by their users. Invoices reflect work that has been completed, whereas quotes reflect potential future work and are most often provided for new system installations. HARDI has found that, over time, the ratio of new invoices to new quotes is a useful indicator of whether a market is trending more toward repair than replace and vice versa.
The numbers show the annual growth rate bottomed out in the spring of 2022 but remained negative through most of the year, indicating that replacement trends were broadly higher in 2022 than in 2021. That figure increased through 2023, peaking in May but generally remaining positive for most of the year. While the three-month growth rate has slowed in recent months — an encouraging sign — they don't expect much of a negative drift in 2024, meaning that repair versus replace trends will broadly remain similar to where they were in 2023.
So why is this change happening? It can't be attributed to any single factor but rather a combination of items. Certainly, higher costs of both HVAC systems and housing in general play a role.
"Adapting to the economy is something contractors need to do. We can't just assume people are going to reach into their pocket and replace," said ACCA CEO Bart James. "Contractors need to help customers get through the current need. People are slowing down on theirspending. People are worried about what is coming and how they are preparing for it. Wages and other things are not keeping up with how fast prices are going up."
James said reading the numbers shows there is a shift in the home improvement market.
"Just look at the Walmart and Home Depot quarterly projections. Walmart did well with more visits but had smaller purchases, while Home Depot did not hit their numbers. That tells you that people are handling investments into housing differently. That will catch up with HVAC, too. "Contractors need to prepare by making investments in their team to meet the needs of the customer. And that need is not always a replacement option but also can be a repair option," James continued.
The sluggish home resale market is another reason for the shift towards a repair market. "Home improvement spending, in aggregate, tends to follow existing home sales totals nationally," Fisher said. "People invest more in their homes prior to selling to boost its value, and new homeowners spend more in their first year of moving than homeowners who stay put. This has major implications for HVAC replacement demand, which, historically, peaks when existing home sales are at their highest and falls off when existing home sales decline.
"Both the 3-month and 12-month growth rates bottomed out earlier in 2023, and while still negative, have slowed significantly," he continued. "We believe that home sale totals are at or nearing their trough, and over the duration of 2024 should steadily improve and finish at or ahead of 2023 totals."
The final reason is the cyclical nature of HVAC. It reflects the shipment cliff from 15 years ago, when the industry contracted 40% after peak shipments in 2005. Contractors cannot replace what was never installed.
How do HVAC contractors deal with this shift? Michel believes they should embrace the repair market.
"The money is better in replacements," he said. "It always has been and always will be. However, margins are better in service. For the next couple of years, anyway, contractors should focus on building up their service business and making money on it."
Since service involves more labor, and labor carries more overhead than equipment and material, keeping a close watch on overhead expenses is a must.
"Contractors need to build the service base, watch your marketing expenses drop, and down the road, the replacement margins and close rates to a satisfied service base will rise," Michel said. "Once we get past the shipment cliff, the replacement market will begin a decade-long run with every year being better than the year before it. We know this because it's what happened in the past, and when it comes to replacements, the past truly is a prologue."
Contractors in most parts of the country are already feeling the pinch of a slower market, and their experiences in 2024 are unlikely to be much different from their experiences in 2023 though rebounds from themilder temperatures we saw during peak months last year would go a long way in improving demand in 2024.
HARDI advises contractors should consider the following six tactics in '24:
