A few weeks prior, while dining with friends, the conversation turned to renewable energy—quite fitting as we had a climate journalist, an activist, and two civil servants at the table.

As expected, my dinner companions were well-versed in the perils of climate change and the pressing necessity to transition to cleaner energy sources. However, a question lingered: Does the UK still require gas as a backup fuel for the electricity grid? Can we rely solely on wind, solar, and batteries during those dreary winter months?

In such discussions, it’s timely that data scientist Hannah Ritchie’s new book has been released. Clearing the Air: A hopeful guide to solving climate change with 50 questions and answers serves as an excellent resource. Thanks to my well-thumbed copy, I was able to guide a friend through various storage solutions that maintain grid power when wind and sunlight are scarce, highlighting the roles of pumped storage, geothermal energy, and hydrogen.

In her previous work, it’s not the end of the world, Ritchie provided a swift education on addressing the planet’s environmental challenges. purify the air, though it maintains the same optimistic outlook, functions more as a practical guide with data-driven answers regarding the journey to achieve net-zero emissions.

Topics are categorized, covering fossil fuels and renewable energy to electric vehicles and domestic heating. Reading through, it’s evident that Ritchie aims to counter the deluge of misinformation and misleading media narratives surrounding the net-zero transition. Her work dispels myths, such as the idea that electric cars will frequently run out of power on highways, heat pumps are ineffective in colder climates, and that there isn’t enough land available for solar energy installations.

purify the air wields the power of scientific research and solid data to combat this misinformation. For instance, one of her addressed questions is whether wind farms pose a threat to birds—a commonly cited criticism from figures like US President Donald Trump. The response is yes; while wind turbines do unfortunately kill some birds, the figure is minimal compared to annual deaths caused by cats, buildings, vehicles, and pesticides.

Nevertheless, wind turbines do threaten certain species, including bats, migratory birds, and birds of prey. Ritchie emphasizes that measures can be taken to mitigate these risks, such as repositioning wind farms, utilizing black paint on turbines, and deactivating blades during low wind conditions. Such nuances are often lost in headlines or political jests, yet they are key to comprehending the advantages and drawbacks of transitioning to clean energy.

The Q&A format of the book makes it approachable, although repetition may set in if read in one sitting. purify the air proves to be a handy reference when dealing with climate-change skeptics during family gatherings.

Throughout, Ritchie’s characteristic optimism shines prominently. She clarifies that viable decarbonization options are available in nearly every facet of the net-zero transition, all without shying away from real challenges or indulging in wishful thinking. The impact is profound; readers will depart informed, hopeful, and reassured that humanity can prevail in the face of the climate crisis. In a landscape rife with fake news and political deception, this book truly brings a breath of fresh air.

Hannah Fry discusses the science of laughter: Monkeys enjoy being tickled, mice giggle | Revealing the formula for life by Hannah Fry

The British sense of humor is cherished among Brits, but it’s natural to assume that many British jokes may be embarrassing to other cultures. There is an interesting point to consider here – humor is not universal. What one finds amusing is not inherent, but rather cultural.

Humor differs significantly from laughter, which is a common experience for all human beings, even the grumpiest ones. Laughter is much easier to comprehend and study scientifically.

For instance, TV producers have long understood that incorporating a pre-recorded “laugh track” can make people perceive something as funnier compared to when they don’t hear that laughter (I’m Looking at You, 90’s Sitcom). However, neuroscientist Robert Provine found that jokes are not even necessary. In a study conducted in 2013, Provine solely played the laugh track, which surprisingly was adequate to induce laughter in nearly all participants.

Provine’s groundbreaking research on laughter involved observing it in real-world settings rather than just in a lab. Observing people laughing in public, he empirically proved that individuals are significantly more likely to laugh in the presence of others than when alone, approximately 30 times more likely. Moreover, laughter is not necessarily a response to finding something funny but serves as a form of social communication, indicating a positive, nonthreatening interaction.

Laughter is not exclusive to humans; it is observed across the animal kingdom. For example, apes enjoy being tickled and vocalize their enjoyment while playing. Kea parrots are known for their playful behaviors and have distinct calls to amuse others. Additionally, mice produce ultrasonic giggles when playing. Rats tickled regularly by their owners exhibit immediate laughter upon the owner’s arrival, displaying excitement for playtime.

However, humor poses a greater challenge in understanding. What makes certain things more amusing than others? And how do you define what is considered amusing, depending on individual perspectives?

One compelling explanation for humor is that it involves the buildup and release of tension. This concept can explain some well-known comedic moments, such as Del Boy falling on the bar, Basil Fawlty hitting a car with a tree branch, or Mark Simmons’ joke at the Edinburgh Fringe: “I planned to sail around the world in the smallest ship, but chickened out.” These instances are humorous, especially when viewed from a non-human perspective.

Generative AI, trained on vast internet data, is adept at replicating various humor styles, including generating jokes based on given parameters. When prompted with a framework like, “I thought I was going to sail around the world in the world’s smallest ship…”, an AI chatbot replied, “I felt like I was sinking.” Not a bad attempt, right?

However, creating the framework itself, i.e., original humor, involves distilling quirky and unconventional ideas that resonate with shared human experiences but lack any firsthand experience of the world beyond online sources. For now, these unique concepts offer intriguing ways to engage with audiences.

Hannah Fry reveals how technology can empower us in health, but cautions that data alone is not the full picture | Unlocking Hannah Fry’s Formula for Life

Throughout history, there have been many individuals who meticulously monitored their weight, but one of the most intriguing figures is Santorio Santorio. In the 1500s, he devoted his life to tracking his body, weighing everything he consumed and everything he excreted.

For a particular scientific investigation, he created what he called a sanctorian weighing chair – a chair placed next to the dining table on a steel scale that closely monitored one’s weight.

His theory was based on the idea that individuals could maintain their weight by consuming the same amount that their bodies expelled (urine, feces, sweat, or what he referred to as “insensible sweat”). If it detected overeating, the chair would lower, making it impossible to reach the food. This would prevent further consumption until the end of the meal.

Despite being mocked at the time, Santorio’s concept had merit. The notion of a personalized, experimental, and quantitative approach to health is undeniably appealing.

Nearly two centuries later, Benjamin Franklin, inspired by Santorio, meticulously recorded his dietary intake and compiled a list of all 13 of his virtues. He marked them whenever he committed an immoral act, monitoring and quantifying his life in great detail.

In the modern era, individuals have pushed boundaries with technology to track various aspects of their lives. For instance, a Reddit user created a beautiful visualization depicting a baby’s sleep and wake times during the initial months of life.

The advancement of wearables has made monitoring our health easier than ever. With technology, we can now effortlessly track various health metrics. AI-powered wearables connected to smartphone apps can monitor sleep patterns, blood oxygen levels, heart rate, and blood pressure.

Having access to objective numbers and data can be reassuring. It can serve as a motivator for achieving our health goals and connecting with communities that prioritize health tracking and accountability. However, it’s essential not to prioritize tracking numbers over happiness and well-being.

When it comes to fitness, remember that numbers are merely proxies for what truly matters. Each individual is unique, and responses to external stimuli vary. While trackers can provide insights into what is “normal” for a person, this data should be used to inform rather than dictate health status. Human bodies are complex and should not be reduced to mere data points.

Hannah Fry’s Formula for Life: Overcoming Procrastination through Understanding Its History

Back in 1830, what would eventually become one of the most renowned novels in French literature was just an empty page. Victor Hugo had been tasked with writing The Hunchback of Notre Dame the year before, but instead of focusing on it, he was preoccupied with other obligations. His publisher informed him that he was running out of time to finish the book, giving him a strict six-month deadline.

To force himself to deliver, Hugo resorted to working in the nude – except for a large knitted shawl. Unable to go out in public, he had no choice but to stay at home and focus on writing. This wardrobe tactic proved successful, as The Hunchback of Notre Dame was completed and published two weeks ahead of schedule on January 14, 1831.

Procrastination is a common challenge that people face when they struggle to find the motivation to complete tasks. Piers Steel, a prominent researcher in the field of procrastination, defines it as “the act of delaying tasks even though you know it will worsen your situation.” Hugo’s experience highlights how overthinking rather than taking action has been a prevalent issue for centuries.

References to procrastination can be traced back to ancient times, with examples found in early Roman, Greek, and Egyptian texts. Hesiod, an ancient Greek poet, warned against procrastination and laziness in his works, emphasizing the importance of diligence. The Hindu scripture Bhagavad Gita also addresses the consequences of procrastination, highlighting its detrimental effects.

While procrastination has always existed, modern factors like social media and technology have exacerbated the problem. With numerous distractions, the way we approach work has evolved, making it easier to procrastinate when tasks are not immediately vital. Companies are now grappling with challenges like “cyber loafing,” where employees waste time online instead of working.

The conventional view that procrastination stems from poor self-control has shifted to emphasizing emotional regulation. Research indicates that procrastination often results from avoiding negative emotions associated with tasks, leading to a cycle of procrastination and negative feelings.

Technology, while contributing to procrastination, also offers solutions. Apps like Forest promote focused work by rewarding users with virtual trees. Generative AI can help overcome creative blocks, providing tools to combat procrastination.

It’s important to acknowledge and address procrastination with self-compassion. Occasional distractions can boost self-esteem and curiosity, ultimately enhancing motivation. Starting with small tasks and gradually progressing can help overcome the discomfort of returning to work after procrastination. Remember, even delayed progress eventually leads to completion.

With constant headlines about floods, bushfires, and record temperatures, it’s surprising how many people think our current generation will be in even worse trouble than when we inherited the planet. Not. But is that belief true? hannah richie I do not think so. She is cautiously optimistic that we may be the first generation to inherit the environment in better shape than it was back then.

She came to this counterintuitive conclusion after a decade of digging into the environmental record as a data scientist at the University of Oxford and principal researcher at the influential online publication Our World in Data.in her new book it’s not the end of the world, Ritchie lays out graphs that show the positive steps we’ve already taken to change our behavior and mitigate climate change, from reducing coal usage to reducing carbon emissions. I am.she speaks new scientist She talks about her growing confidence that we can solve the world’s environmental problems and lists some key trends that give us hope that we can turn things around.

Alison George: I’m talking about that day. report We’ve seen a dramatic increase in online searches related to “environmental anxiety.” Still, you study long-term environmental trends and are reasonably optimistic.

Hannah Ritchie: There’s still some anxiety and worry, but I think there’s now a sense of optimism that things can change. That fear is completely valid, and I can understand why people feel that way. I feel it. However, that feeling alone is not very helpful. You need to combine your senses…
