The Power of a Gentle Touch

An interesting film.

On Sunday evening Jean and I watched a documentary on touch. It was most interesting and included the obvious thought (that I needed reminding of) that babies when they are born cannot see more than 30 centimetres and cannot hear at first. So touch is vital for the health and early bonding of the babe and its parents with the mother being the dominant parent and the provider of breast milk.

Then yesterday I poked around online and found that the benefits of touch not only were for the very young but also for all ages and also were more broadly available across many animals, especially dogs.

But here’s the first film:

Touch shapes us as humans. Indeed, touch is fundamental to what makes us social beings. Touch influences how we perceive stress and pain, who we trust and who we fear. How does this work? And what happens to us in the absence of touch? Gentle touch is vital for us humans. It creates the first contact with the world for newborns, giving us a sense of security and belonging. Touch influences our immune system, and on our feelings for our fellow human beings. Especially strong feelings, such as love or compassion, can be better conveyed through touch than through words, facial expressions or gestures. Given how important touch is, it’s no surprise that humans have a highly specialized system devoted exclusively to perceiving gentle touch stimuli. Why does the touch of a stranger feel so different to that of someone we are emotionally close to? What is happening in our brain – and what role does the brain play in all this? In an era of social distancing, touch research is becoming increasingly relevant. How does it affect us, and our relationships, when we are required to keep our distance? Researchers explore what role touch plays in our physical and emotional well-being, and what the consequences are when touch is missing.

Then moving on I found an article on the Johns Hopkins Medicine website called The Friend Who Keeps You Young.

It opens:

Adopting a pet may seem like a selfless act, but there are plenty of selfish reasons to embrace pet ownership. Research has shown that owning a pet provides an amazing array of health benefits, says Jeremy Barron, M.D., medical director of the Beacham Center for Geriatric Medicine at Johns Hopkins.

Not ready for a full-time furry friend in your home? Offer to walk a neighbor’s dog, cat-sit for a friend, or donate time at a local animal shelter—even short interactions provide enough pet exposure to reap some of these rewards.

And that wasn’t the end, far from it!

HelpGuide.org had a powerful article The Health and Mood-Boosting Benefits of Pets. Here’s how it starts:

The benefits of pets

Most pet owners are clear about the immediate joys that come with sharing their lives with companion animals. However, many of us remain unaware of the physical and mental health benefits that can also accompany the pleasure of snuggling up to a furry friend. It’s only recently that studies have begun to scientifically explore the benefits of the human-animal bond.

Pets have evolved to become acutely attuned to humans and our behavior and emotions. Dogs, for example, are able to understand many of the words we use, but they’re even better at interpreting our tone of voice, body language, and gestures. And like any good human friend, a loyal dog will look into your eyes to gauge your emotional state and try to understand what you’re thinking and feeling (and to work out when the next walk or treat might be coming, of course).

Pets, especially dogs and cats, can reduce stress, anxiety, and depression, ease loneliness, encourage exercise and playfulness, and even improve your cardiovascular health. Caring for an animal can help children grow up more secure and active. Pets also provide valuable companionship for older adults. Perhaps most importantly, though, a pet can add real joy and unconditional love to your life.

Dogs are the perfect companions to us!

Building Bridges: How Dogs Understand Humans and How We Can Improve Our Communication with Them

By Raphael Wildcom.

Dogs have been our faithful companions for thousands of years, and during that time, they have evolved to become incredibly attuned to human emotions and communication. Their ability to understand us and our ability to communicate with them has led to a unique bond between our two species. 

In this article, we will explore how dogs understand humans and offer some tips on how we can improve our communication with our canine friends.

How Dogs Understand Humans

  1. Body language

One of the most crucial ways dogs interpret our emotions and intentions is through our body language. Dogs are highly perceptive when it comes to noticing our posture, eye contact, and movements. They can sense if we are relaxed or tense and often respond accordingly.

For example, a cute Shiba Inu puppy might approach a person exhibiting relaxed body language while avoiding someone who appears tense or stressed.

  1. Facial expressions

Dogs are remarkably adept at recognizing human facial expressions. Research has shown that they can distinguish between expressions of happiness, sadness, and anger, among others. This ability allows them to adjust their behavior depending on our emotional state.

  1. Vocalizations

Although dogs may not understand the specific words we use, they are incredibly sensitive to the tone and pitch of our voices. They can pick up on the emotional content of our speech, which helps them gauge our emotions and intentions. For example, a dog might become excited when they hear a high-pitched, happy voice or become submissive when they hear a low, stern voice.

  1. Training and commands

Dogs can learn to associate specific words or gestures with actions or objects through training and repetition. This ability allows them to respond to our commands and communicate with us effectively. For example, a dog might learn to sit when they hear the word “sit” or see a specific hand signal.

  1. Scent and pheromones

Dogs possess an extraordinary sense of smell, and they can pick up on subtle changes in our body odor, which may be indicative of our emotional state. For example, a dog might be able to detect the scent of stress-related hormones and respond accordingly.

  1. Social cues

Dogs are skilled at observing and interpreting social cues within a group or family. They understand relationships between people and often respond to the social hierarchy within the household. For example, a dog might defer to the person they perceive as the leader of the family.

Improving Communication with Your Dog

  1. Be consistent

Consistency is key when it comes to communicating with your dog. Use the same words, tone, and gestures for specific commands, and make sure all family members are on the same page. This consistency will help your dog understand what you expect from them and make it easier for them to respond correctly.

  1. Use positive reinforcement

Reward your dog with praise, treats, or playtime when they respond correctly to a command or exhibit desirable behavior. Positive reinforcement is an effective way to strengthen your communication with your dog and encourage them to repeat the desired behavior in the future.

  1. Pay attention to your dog’s body language

Learn to recognize the subtle signs your dog uses to communicate their emotions and intentions. By understanding their body language, you can respond more effectively to their needs and create a stronger bond.

  1. Be patient and persistent

Training and effective communication with your dog takes time and effort. Be patient, and understand that your dog may need repetition and practice to grasp new commands or break old habits. Persistence and consistency will pay off in the long run.

  1. Learn from the experts

Consider enrolling in a dog training class, consulting with a professional dog trainer, or reading books on dog behavior and training to improve your communication skills and understanding of your dog’s needs.

  1. Socialize your dog

Expose your dog to various people, animals, environments, and situations from an early age. Socialization helps your dog become more comfortable in different settings and makes them better equipped to understand and respond to different cues from humans and other animals. Well-socialized dogs are generally more confident, adaptable, and better communicators.

  1. Develop a routine

Dogs thrive on routines, as they provide structure and predictability. Establish a daily routine for feeding, walks, playtime, and rest. A consistent routine helps your dog feel secure and makes it easier for them to understand your expectations.

  1. Be aware of your own body language and emotions

Remember that your dog is constantly observing you and responding to your body language and emotions. Be mindful of the signals you send through your posture, facial expressions, and tone of voice. By being aware of your own non-verbal communication, you can create a more harmonious and effective relationship with your dog.

  1. Use clear and simple commands

When giving your dog a command, use clear, simple words or gestures that are easy for them to understand. Avoid using multiple words for the same command or giving commands when you are angry or frustrated, as this can confuse your dog and hinder communication.

  1. Engage in interactive play and training

Spend time playing with your dog and engaging them in activities that challenge their mind and body. Interactive play and training sessions can strengthen your bond, improve communication, and provide mental stimulation for your dog.

Conclusion

By understanding how dogs interpret our emotions and intentions and implementing strategies to improve communication, we can forge an even stronger bond with our canine companions. This deeper connection not only enhances our relationship with our dogs but also contributes to their overall well-being and happiness. 

With patience, consistency, and a commitment to understanding each other, we can continue to enjoy the unique and enriching bond that humans and dogs have shared for thousands of years.

Fun DIY Toys to Keep Your Cat Entertained

Keep your cat entertained with these easy DIY toys, including puzzle toys and toilet paper roll toys. Challenge your cat’s mind and provide hours of fun with these ideas

Fun DIY Toys to Keep Your Cat Entertained

Cats are known for being playful and curious, so it’s important to give them things to keep them occupied and their minds working. But store-bought toys can be expensive, and your cat may not always be interested in them.

That’s why making your own toys is a good idea. Making your own cat toys is not only cheaper, but it also allows you to make them just the way your cat likes them. In this article, we’ll talk about ten fun toys you can make to keep your cat busy.

  1. Cardboard fort

A cardboard box is one of the easiest and most useful toys you can make for your cat. You can make a box fortress by cutting holes and tubes in the box and filling it with soft bedding. Cats love to hide and look around, and a cardboard box fort is the right place for them.

Find a large cardboard box to start making your cardboard fort. Cut holes and tubes into the sides of the box, making sure the edges are even so the cat doesn’t get hurt. 

You can cut the paper with scissors or a utility knife. Then put something soft inside the box, such as a blanket or towel. Your cat will love hiding in his new fort and exploring it.

  1. Pen game

Cats love feathers and you can make your own feather toy by tying the feathers to a string or stick. Your cat will enjoy chasing and pouncing on feathers, which will exercise them, keep their mind active, and remind you that cat shed.

Start by getting feathers to make a feather toy. You can use feathers you find on the street or feathers bought from a craft store. Use glue or tape to attach the feathers to a string or stick. Make sure the feathers are well attached so they don’t fall off when the kids play. Then hang a feather toy in front of your cat and watch it jump and run after it.

  1. Socks with catnip

Cats love the natural catnip stimulant, and you can make your own catnip toy by placing dried catnip in a sock and tying a knot at the end. Your cat will enjoy rubbing and biting on the sock, and the smell of catnip will keep her interested.

Find a clean sock to use as the base for your catnip sock. Put the dried catnip in the sock and then tie a knot at the end so the catnip stays inside. You can also put bells or wrinkled paper inside the sock to make it more interesting. Then give your cat a sock and watch her rub and bite into it, enjoying the smell of catnip.

  1. Post for scratching

Cats naturally love to scratch, but if you give them room to scratch, they won’t scratch your furniture. You can make a scratching post by wrapping string or carpet around a cardboard tube or wooden pole.

Find a sturdy cardboard tube or wooden pole to start making your scratching post. Cut a piece of string or carpet long enough to go around the pipe or pole. Then wrap the rope or cloth tightly around the pipe or pole and glue or staple it to keep it in place. Make sure the scratching post is high enough so that the cat can stretch out its entire body when using it. Place the scratching post where your cat likes to scratch and rub it with catnip so the cat can use it.

  1. Track for ping pong balls

Make a ping pong ball track a fun and responsive toy for your cat. Make a path for the ping pong ball by cutting holes in the cardboard box and attaching the cardboard tubes. Your cat will love trying to catch the ball when you hit him with the bat.

Find a wooden box to start making a ping pong ball track. After making holes in the sides of the box, make sure they are large enough for a ping pong ball to fit through. Then make a maze by inserting cardboard tubes into the holes. The tubes can be glued with hot glue or tape. Finally, place the ping pong ball in the maze and watch your cat try to catch it by hitting it.

  1. Tunnel for paper bags

A paper bag tunnel is another easy and cheap toy you can make for your cat. You can make a tunnel for your cat by cutting the bottom out of a paper bag and sticking several bags together. You can also crumple up some paper and put it in bags to make them rustle and make the animals more excited.

Collect some paper bags to start making the paper bag tunnel. Make a long tunnel by cutting out the bottom of each bag and taping them together. You can also put crumpled paper inside the bags so that the cat makes noise while playing inside. Your cat will have a great time exploring his new cave and hiding in the bags.

  1. Toy fishing rod

Another fun toy for cats that looks like their natural prey is playing with a fishing rod. Stretch a toy or some feathers and tie them to a stick or dowel. Your cat will enjoy chasing and jumping on the toy, which will keep her active and stimulate her brain.

Find a stick or fishing rod to start making a fishing rod toy. Use glue or tape to attach the toy or feathers to the string, and tie the other end of the string to the stick. Hang the toy in front of your cat and watch it run and jump on it.

  1. A toy that gives treats

A toy that gives treats is a fun way to give your cat a treat and keep them entertained at the same time. Cut holes in a plastic bottle and fill it with treats to make a toy that dispenses treats. To get a treat, your cat will break the bottle.

Find a plastic bottle to start making a toy that gives out treats. Use a utility knife or scissors to cut some small holes in the sides of the bottle. Then put the best treats for your cat into the bottle. Your cat will love to hit the bottle and try to get treats out of the holes.

 Conclusion 

After all, making your own cat toys is a great way to keep them entertained and stimulated while saving money. But when you make these toys, it’s important to put your cat’s safety first and give her a range of toys that stimulate different senses. Don’t forget to play with your cat to bond with her and give her some exercise.

Journalism.

A start to a fascinating programme on BBC Radio 4.

Yesterday morning (Oregon time) had me listening to a new series on BBC Sounds. It was Frontlines of Journalism. Here is what the Beeb had to say about it:

Released On: 27 Feb 2023

Available for over a year

In the spring of 2023, twenty years after the Americans, the British and their allies invaded to overthrow Saddam Hussein, BBC International Editor Jeremy Bowen was reporting from Iraq for the BBC. He described the invasion as ‘a catastrophe’. Taking you to some of the most difficult stories Jeremy and other journalists have covered; in this episode – why impartiality is not about trying to get perfect balance, the truth lying somewhere in the middle.  Often it does not.   Jeremy speaks with: journalist Rana Rahimpour who was born in Iran but left when she was 25 to work for the BBC; former BBC bureau chief Milton Nkosi, who grew up under apartheid in Soweto, South Africa; journalist and environmentalist George Monbiot, and CNN’s Chief International Anchor Christiane Amanpour.

Presenter: Jeremy Bowen Producer: Georgia Catt Assistant Producer: Sam Peach Additional research: Rob Byrne Series mixing: Jackie Margerum Series Editor: Philip Sellars.

But in wanting to present a little more to you readers, I did some research on the topic and came across this article published by the Reuters Institute at the University of Oxford. I cannot see a warning about not sharing this with you.

Impartiality is still key for news audiences. Here’s how to rethink it for the digital age

Our research shows people still value the ideal of impartial news. A new report offer suggestions to adapt it to a challenging environment.

Tuesday 19 October 2021

Most people agree that news organisations and journalists should reflect all sides of an issue and not push a particular agenda – at least when asked about it in surveys. Our 2021 Digital News Report finds this to be true across countries and age groups. 

However, many people feel that the media often fail to live up to this ideal. Our surveys consistently show that committed partisans believe that traditional media coverage is unfair, especially in countries where debates about politics or social justice have become deeply polarised. In recent years we’ve also seen an increase in opinion-led television formats such as Fox News/MSNBC in the United States, GB News in the UK and CNews in France, while many traditional print publications have focussed on distinctive and robust opinion as a way of standing out online.

Together with the growth of partisan websites, YouTubers and podcasters, audiences now have access to a wider range of views than ever before. Against this background, some have questioned traditional approaches to impartiality that try to represent all points of view within a single broadcast or publication. Other critics go further – arguing that impartiality has given extreme or unrepresentative views undue prominence, through its focus on balance, helping to legitimise climate change deniers and anti-vaxxers amongst others.

This all raises the question: how relevant is impartial and objective journalism to audiences today? The Reuters Institute commissioned market research company JV Consulting to carry out qualitative research in four countries – Brazil, Germany, the UK, and the US – with different news markets, traditions of public broadcasting, and systems of media regulation. They conducted a series of focus groups and in-depth interviews on our behalf in February and March 2021 with politically and ethnically diverse groups of older and younger people interested in and engaged with news (52 people in total).

These are some of the key findings of the report:

  • Engaged audiences in the four countries researched still care about impartiality and say it helps define news, even if some consider it an impossible ideal. They want journalists to focus on facts, objectivity and fairness, and to steer clear of opinions and bias in reporting, leaving them to decide for themselves how they feel about the news. Alongside accuracy, impartiality is a foundational value of news that underpins audiences’ trust.
  • People recognise the risk of giving exposure to extreme views or one side in the name of balance. However, evidence from this group of engaged users is that they are even more concerned about the suppression and silencing of viewpoints. There are particular misgivings about this in Brazil and Germany, where twentieth century history frames some people’s views.
  • Most participants recognise that there were some topics (e.g., science stories, natural disasters, and questions of social justice) where there were not always two or more sides to represent. Here, many felt there should be more latitude for journalists to present just one perspective or an established point of view. There are also expectations that journalists will show greater empathy and connection in their reporting than perhaps traditional interpretations of impartiality have allowed in the past.
  • Across countries, newer digital formats such as social media are perceived as carrying more risk of bias along with the growth of more informal and entertaining broadcast formats such as chat shows and podcasts. Impartiality is more vulnerable in these contexts, as well as when the news is emotive or controversial, because journalists’ personal views risk slipping out in the impulse to engage, although the subject and intention have a bearing on how audiences feel about this.
  • Younger people, who have grown up using more informal and digital sources, tend to have different expectations of impartiality, often looking for journalism that aligns with their values. But overall, their underlying attitudes and desires are remarkably similar to older people’s.
  • Different countries’ news traditions shape people’s experiences and expectations. Audiences in the US cannot envisage a world without partisan news outlets, but in the UK and Germany, with their public service traditions, most audiences still laud the upholding of impartiality.
  • Respondents also delineate between news reporting (where impartiality is expected) and opinion/commentary (where people expect that views are argued for). Importantly, many told us that they often find it difficult to distinguish between the two, especially online. Interviewees like news and they like opinion, but want them very clearly separated. 

It is important to recognise that not all news organisations are committed to impartiality: indeed, some make a virtue of creating news and opinion with a clear point of view. But most will want to take note of audience desires for a range of views to be represented and to see clearer labelling of news and opinion. For news organisations that are committed to impartiality, the report highlights the increased dangers in areas where journalism is more informal or accessed in distributed environments. Public media like the BBC have already embarked on updated training and issued new guidelines on these issues. Audiences have also sent a clear signal in this report that they would like much greater transparency over why certain perspectives are included or excluded, however difficult this may be in practice.

Finally, the report notes that given the importance of social media, search and other access points, technology platforms such as Facebook, Google and Apple, will also need to develop clearer guidelines on impartiality – as their own trust levels will depend on fair implementation of policies around inclusion and exclusion, whether by algorithm or human intervention.

Now this isn’t everyone’s cup of tea but when one thinks of the enormous amount of news and information one gathers from the television, the radio, the press and a wide variety of online sources then thinking a little more about the truth of what we are being told is crucial to us making wise decisions. including voting where appropriate.

People still value the ideal of impartial news; there is no question about that!

One of the numerous effects of a warming climate.

An article that I wanted to share with you!

There is no question that we are warming the world, and in my mind, there’s very little doubt that it is us older persons who are the cause. Take this chart, for example, where the effects of populations in the 1980’s – 2000’s had a dramatic impact on the worsening trend:

The reason for today’s post is to share an article that writes of the science of precipitation.

THE PHYSICS OF PRECIPITATION
IN A WARMING CLIMATE

WRITTEN BY DR ASHLEIGH MASSAM

The scientific consensus on climate change is that atmospheric temperatures are rising and will continue to rise. Mean global temperatures are already 1˚C warmer than preindustrial times (relative to 1850–1900), predominantly due to human activity increasing the amount of greenhouse gases in the atmosphere (IPCC, 2018a). The 2020 Paris Conference of Parties (COP) agreed on the aim of a 1.5˚C cap on climate change-induced warming, although without rapidly introducing measures to reduce carbon and greenhouse gas emissions, global warming could easily go beyond this limit. 

In fact, the Intergovernmental Panel on Climate Change (IPCC) warns that even a mean global temperature increase of 1.5˚C will lead to an increase in the frequency and intensity of rainfall events. But what links a warmer climate to an increase in intense rainfall events? This blog post will explain the physics behind the changes to precipitation rates in a warming climate.

A SIMPLE OVERVIEW OF THE PHYSICS

Climate projections simultaneously warn of higher annual mean surface temperatures, higher rates of intense rainfall and more frequent intense rainfall events. The atmospheric moisture content increases with respect to a change in temperature – essentially, the warmer the atmosphere, the more water is held in the atmosphere, and therefore higher rates of precipitation can be expected.

This is explained by the Clausius-Clapeyron relationship between surface temperature and water vapour. According to the Clausius-Clapeyron relationship, atmospheric water content increases by between 6 and 7% per 1 °C. Therefore, even just an increase of 1.5°C could result in ~9% more water in the atmosphere, which could have a major impact on storm systems and subsequent rainfall.

Storm systems travelling across oceans will have an increased moisture content from water evaporated from the sea surface, forming a larger storm system and therefore more precipitation. JBA has recently discussed the risk of flooding from intensifying rainfall due to climate change and this will be explored in respect to storm systems later in this blog.

HOW PRECIPITATION IS FORMED

In meteorology, precipitation can be liquid or solid water that falls from the atmosphere and reaches the Earth’s surface. Types of precipitation include rain, sleet, or snow, depending on the temperature of the atmosphere. During the water cycle (fig. 1), water evaporates from the surface into the atmosphere, and changes state from liquid to vapour. The water vapour forms cloud droplets, which join together until the heavy droplets fall from the clouds as precipitation. Several processes affect this simple view of the journey from evaporation to precipitation.

Figure 1: A diagram of the water cycle showing the connections between water masses, the atmosphere and the transpiration and condensation of water vapour.

THE SURFACE TEMPERATURE – PRECIPITATION RELATIONSHIP IN MORE DEPTH

The connection between precipitation and surface temperature is defined by the Clausius-Clapeyron equations. The Clausius-Clapeyron equations calculate the energy required to cause a chemical reaction at a given pressure. In terms of precipitation, the Clausius-Clapeyron equations can be used to calculate the thermal energy required to condense water vapour into droplets when the atmospheric pressure is known. 

When water droplets are evaporated into the atmosphere, they travel upwards. As the Clausius-Clapeyron relationship is dependent on atmospheric pressure, the thermal energy requirement for a phase change is lower at a lower pressure. As the water droplets travel upwards, two things happen: 

  1. The atmospheric pressure decreases, and 
  2. The atmospheric temperature cools (this is known as the temperature lapse rate and is typically estimated at -6.5°C per kilometre). 

When the water vapour reaches an elevation where the atmospheric pressure and temperature satisfy the Clausius-Clapeyron relationship, the water vapour condenses into cloud droplets. 

IMPACTS OF A WARMING CLIMATE ON THE SURFACE TEMPERATURE – PRECIPITATION RELATIONSHIP

The release of carbon dioxide, and other greenhouse gases, into the atmosphere by humans has already led to climate change in the form of atmospheric warming. Long-term measurements show that the atmosphere has already warmed by 1°C since 1900. IPCC projections suggest that additional warming is inevitable, and attempts are being made to keep global atmospheric warming to under 1.5°C. Although, as previously mentioned, this could still increase the frequency and intensity of rainfall (IPCC, 2018b). To understand how an increase in annual mean surface temperature will influence rainfall events, we can apply the Clausius-Clapeyron relationship in a geographical context. 

As the Clausius-Clapeyron equations define the relationship between vapour and pressure, they can also be used to define the saturation vapour pressure with respect to temperature. In meteorology, the saturation vapour pressure is the maximum pressure of water vapour, at a given temperature, before it condenses. Therefore, the pressure required to condense a water droplet increases exponentially with respect to a change in temperature. 

This means that the Clausius-Clapeyron relationship can be used to determine the moisture content of the atmosphere. Warmer atmospheric temperatures will increase the atmospheric moisture content before condensation because the atmospheric pressure will not be affected by climate change in the same way as temperature. This results in the previously mentioned calculation that moisture content will increase by ~6.5% in the atmosphere per 1°C increase in temperature and means that atmospheric warming of 1.5°C will yield an increase in atmospheric moisture content of ~9%.

THE EFFECT ON STORMS AND PRECIPITATION

This ~9% increase has an impact on storm systems and therefore rainfall. Hurricane Harvey made landfall on the coast of Texas in August 2017. Over seven days, areas of Texas including Galveston and Houston experienced nearly 1.5 metres of rainfall. 

Research published since the event suggests that the intensity of Hurricane Harvey is attributable to a combination of the storm stalling over one location and climate change. The Gulf of Mexico, the source of moisture for Hurricane Harvey, has experienced anthropogenic-induced sea-surface temperature warming of 1°C since preindustrial times (Pall et al., 2017; Trenberth et al., 2018). Comparing Hurricane Harvey’s precipitation records with an equivalent event from 1950, extreme value analysis concluded that climate change contributed to a 5-7% increase in rainfall rates covering the full region affected by the hurricane (Risser and Wehner, 2017). 

With an increase in rainfall events and the wider impacts of climate change, it’s important for organisations to think about the potential risk to their business. JBA’s UK Climate Change Flood Model assesses and quantifies future flood risk in the UK under a warming climate and complements our range of global Climate Change Analytics, helping clients to understand and manage the effects of climate change on their assets and to enable long-term planning.

The IPCC states what is clearly known in science circles; a warmer atmosphere equals more moisture in the air and that translates into more rainfall.

It comes down to warmer atmospheric temperatures increasing the atmospheric moisture content before condensation, simply because the atmospheric pressure will not be affected by climate change in the same way as temperature, as was described earlier in the paper. The reference to Hurricane Harvey was very powerful.

The world has to focus on climate change in an urgent manner. Because there isn’t a great deal of time, something like 10 years, at most, to bring about huge changes in the way we consume energy.

Picture Parade Four Hundred and Eighty-Three

The last day of April, 2023, brings a change in the Picture Parades.

My son, Alex, is a very keen photographer and has taken many beautiful photos of birds. He wants to build his following especially on Instagram (that is a link to Alex’s page) and I was very willing to assist him in his endeavour.

So starting today I will be posting the photographs taken by Alex and repeating this every other Sunday. In other words, I shall now be alternating between birds and dogs for as long as is possible.

But first of all here is Alex’s QR code.

Alex uses an Olympus camera, an OM-1, and his lens is an Olympus M zuiko 150-400TC pro. A feature of the camera is the continuous shooting rate of 130 frames per second that Alex uses to good effect; as you can see.

So if you are interested in photography, please go across to this Instagram link and revel in the wonderful pictures featuring wildlife from the UK🇬🇧, mainly in the counties of Somerset, Gloucestershire and Bristol.

Next Sunday we are back to dogs!

Being a responsible dog owner

A guest post from Souvik Ghosh.

From time to time various persons are in touch asking if I will accept a guest post. As long as the author is not connected to a commercial organisation then I am more than willing to accept.

The Benefits of Spaying or Neutering Your Puppy

By Souvik Ghosh.

Spaying is the removal of a dog’s reproductive organs, while neutering is the removal of a dog’s testicles. Both of these procedures are usually completed between the ages of six to nine months old. The decision to spay or neuter your puppy is an important one, and one that every pet parent should consider carefully. Spaying or neutering your puppy can have many benefits; both for your pet, and for pet owners. In this article, we will explore the many benefits of spaying or neutering your puppy.

1. Cost Benefits

A. Lower veterinary expenses

 By sanctioning spaying or neutering your puppy, you can spare yourself incurring costly veterinary bills. Not only that, but spayed and neutered pets often require fewer vet visits overall than unaltered animals, thus resulting in further financial savings.

B. Avoidance of unwanted litters and associated costs

 Opting to spay or neuter your puppy will avoid the costs associated with an unwanted or unexpected litter. Having a litter of puppies can involve additional health care expenses, such as vaccinations or deworming, as well as other costs such as food, housing supplies, and potential vet visits due to complications or illness. What’s more, finding homes for each of the puppies can take a considerable amount of time and money. If a litter is born and is not able to be cared for or placed in a permanent home, euthanasia may also become a cost consideration.

C. Reduced potential for destructive behaviors

 Spayed and neutered pets are less likely to display destructive behaviors associated with hormones, such as urine spraying, marking territory, escaping from the house, stray breeding, and aggression. Dealing with these behaviors can involve costly fence repair, kenneling, veterinary bills, and in extreme cases even legal fees. By taking preventative measures and having your puppy spayed or neutered, you can save yourself considerable financial hardship in the long-run.

2. Health Benefits

A. Reduced risk of certain cancers

 Spaying or neutering your pet has many potential health benefits for your pup. First, spaying or neutering your puppy can reduce their risk of certain cancers. Spayed females are at almost no risk for certain types of ovarian and uterine cancer, while neutered males are at a reduced risk of developing prostate cancer.

B. Decreased risk of infections and diseases

 In addition to curbing cancer risk, spayed or neutered puppies also have decreased risk of bacterial and viral infections, as well as other dog diseases, such as Urinary Tract Infection or “cherry eye.” Unneutered male dogs are a lot more likely to develop testicular tumors, while unspayed female pups are more likely to get vaginal infections or mammary tumors.

C. Prevention of reproductive issues

 Spaying or neutering your puppy can also prevent reproductive issues such as false pregnancies, proestrus, and ovarian cysts. Spaying can also reduce “hump” behavior – or the act of mounting other animals – as well as “marking” their territory by urinating on objects or other animals. If a male dog hasn’t been neutered, these behaviors may continue into adulthood.

3. Behavioral Benefits

A. Reduced aggression and territorial tendencies

 One of the primary behavioral benefits is that spayed or neutered puppies will have reduced aggression and territorial tendencies. Unneutered animals are more likely to attempt to protect their territory, which often manifests as aggressive behavior. By removing the instinct to mate and reproduce, these issues can be avoided.

 B. Decreased likelihood of wandering or escaping

 Another advantage is that spaying or neutering your puppy can decrease the likelihood of them wandering or escaping from home. Unneutered animals are more likely to attempt to find a mate, and as a result may be more tempted to roam. By removing this instinct, your puppy can enjoy a safe and secure living space.

C. Less marking and mounting behaviors

 Spaying or neutering your pet can help them to avoid certain sexual impulses. Unneutered animals are more likely to engage in marking and mounting behaviors, which can be embarrassing and bothersome. This can be avoided by removing the unneutered dog’s natural urges to seek out a mate.

4. Community Benefits

A. Control over population and homelessness

 The most obvious benefit of spaying or neutering your puppy is that it helps to control the overall population and reduce homelessness. When dogs reproduce without consequence, the population grows dramatically and shelters become overwhelmed with strays. These strays can be quite disruptive to the community, especially if they’re aggressive or overly vocal. By having your pet spayed or neutered, your community benefits significantly by avoiding this population surge.

B. Reduced noise and nuisance behaviors

 You can also reduce the amount of noise and nuisance behaviors that can plague a community. Dogs can become territorial if they haven’t been neutered or spayed, which can affect their overall behavior. Un-neutered dogs are more likely to bark more, roam, and even become aggressive. This can be a nuisance to neighbors, and even other pet owners in the area. By having your puppy spayed or neutered, your pup won’t be as prone to these behaviors, making it easier to live in harmony with your surrounding community.

C. Improved relationships with neighbors and other pet owners

 Having your puppy spayed or neutered can improve relationships with your neighbors as well as other pet owners. It can help ensure it’s better behaved when around people, making it much easier for neighbors or other pet owners to interact with your dog. It may even help build a friendlier, less fearful relationship between people and your pup, making it easier for your neighbor to come over for a visit. And better relations with pet owners in the area can help strengthen the bond between community members.

Conclusion

 Spaying or neutering your pet can have numerous benefits, both medically and behaviorally, and it is important to consider if it is the right fit for you and your pet. We would encourage all pet owners to take the steps needed in order to be responsible pet owners, and spay or neuter their pup. By doing so, you can help ensure your pet lives a long and healthy life, while contributing to a kinder, more compassionate society.

That last sentence says it all. I quote, “By doing so, you can help ensure your pet lives a long and healthy life, while contributing to a kinder, more compassionate society.“

Who doesn’t want a kinder and more compassionate society!
