【讀者回應】 Reflections on Your Articles: Truth vs. Fact and Climate Change

Dear Simon,

I recently read your two-part article on "Truth vs. Fact" and its implications for climate change. I found it thought-provoking and wanted to share some of my reflections. After semi-retiring in 2015, I undertook personal studies on climate change and compiled a 45page self-study PDF on the subject.

To start, science does not claim to provide absolute "proof" but builds knowledge through evidence, always open to revision as new data emerges. In this way, science does not o   er fixed, immutable "truths." Unfortunately, politicians often cherry-pick evidence to support short-term, and often shortsighted, goals.

Scientific research, especially in climate science, is challenging and sometimes tedious— think of researchers drilling ice cores in the Arctic and Antarctic. Meanwhile, politicians might mock their efforts over drinks at a bar. This leads to the million-dollar question: Who should we trust to uncover the "truth"? The fact remains that science, not politics, is the tool for understanding our world.

Attached below is my three-page conclusion on the topic. Please note that a couple of links may no longer work, as the publishers appear to have taken them down.

Chapter 15

Two Devastating Environmental Pollution Facts:

• 3.3 Million Global Deaths from Air Pollution Each Year

• Half of the World’s Animals Have Disappeared Since 1970

Key Questions:

• How Does China Handle Air Pollution from Coal?

• Will Earth Survive the Energy Crisis in 2050?

• What Are the Top 10 Energy Sources of the Future?

• The Holy Grail: Thermonuclear Fusion Beta by 2017

• Germany: A Good Energy Policy Reference

• Final Thoughts on Climate Change & the Energy Crisis

 

The Energy and Pollution Crisis

Today, humanity consumes an astonishing amount of fossil fuel energy, with demand skyrocketing at an alarming rate. It is well understood that this reliance on fossil fuels has severe environmental consequences. The massive release of carbon dioxide contributes to catastrophic climate change and pervasive pollution.

Outdoor air pollution alone claims approximately 3.3 million lives globally each year, according to researchers. Sources range from cooking fires in India to traffic emissions in the United States and fertilizer use in Russia. Smoldering cooking and heating fires in India and China are the largest contributors, responsible for one-third of the deaths linked to outdoor pollution, according to study co-author Jos Lelieveld of the Max Planck Institute for Chemistry. Without stricter regulations, deaths from outdoor air pollution are projected to double to 6.6 million by 2050.

The Disappearance of Wildlife

A shocking report from the World Wildlife Fund (WWF) reveals that half of the world’s animals have vanished since 1970 due to uncontrolled human expansion. Populations of mammals, birds, reptiles, amphibians, and fish have declined by an average of 52% in the past 40 years.

In Britain, for example, the turtle dove population has plummeted by 95%. Other species, including seals, toads, red squirrels, moths, dormice, hedgehogs, and hares, are also in serious decline. The WWF describes the report as a "wake-up call," urging people to reduce consumption.

Mike Barrett, WWF Director of Science and Policy, commented, "It’s certainly very concerning. If this trend continues, we will lose even more animals." The report highlights that the situation is particularly dire in low-income countries, where wildlife populations have declined by an average of 58% between 1970 and 2010.

China's Reliance on Coal and the Environmental Consequences

China depends heavily on coal to power its economy. Coal-fired power plants and steel mills operate around the clock, and in rural villages, coal remains a primary fuel for cooking. This reliance raises a critical question: has China made meaningful efforts to educate, implement, or enforce greenhouse gas emissions reductions or environmental control policies?

 One striking example is the coal-mining city of Linfen (臨汾) in Shanxi Province, which has become a symbol of the devastating human and environmental costs of coal dependence. A film documenting the situation shows hundreds of coal trucks driving in and out of Linfen daily, spreading coal dust into the air. Shockingly, most residents do not wear masks to protect themselves from the polluted air.

 This raises questions: Do Chinese genuinely genuinely care about environmental issues and public health? Or are bureaucracy and greed undermining pollution control policies? These entrenched attitudes are highlighted in the renowned documentary Under the Dome, discussed below.

Under the Dome: A Landmark Documentary on Air Pollution

In 2014, Chai Jing (柴靜), a former CCTV news host and journalist, released a groundbreaking self-made documentary titled Under the Dome (穹頂之下的霧霾調查,同呼吸共命運). This two-hour documentary offers a comprehensive, insider’s perspective on China’s air pollution crisis. It gained immense popularity, with over 150 million views on its first day online, before being censored by Chinese authorities a week later.

The documentary, which is available with English subtitles, provides a meticulously detailed and well-organized exploration of the roots of China’s air pollution problem. Chai Jing combines scientific analysis with real-world examples, including interviews with government officials that reveal deep-seated bureaucratic resistance and greed obstructing the environmental policies listed in state plans.

 Her work is a testament to courage and dedication. Despite significant personal and professional risks, Chai Jing succeeded in creating an impactful production that challenges powerful interests and raises awareness. After watching this documentary, one cannot help but admire her bravery and commitment to environmental advocacy.

The Path to 2050: Climate Change, Energy Crisis, and Hope

By 2050, the global population is projected to reach nine billion, placing unprecedented demands on the world's resources—especially energy. China's rapid expansion, with one new coal power plant added each week and lax enforcement of greenhouse gas emissions, contributes significantly to the uncontrolled release of CO2 into the atmosphere. This raises a critical question: Are we on an inevitable path to climate catastrophe, or can we turn the tide?

Despite the challenges, there is a ray of hope. Climate scientists are exploring solutions across various fronts, and the road to 2050 doesn’t have to be bleak. With innovative individuals and extraordinary projects leading the way, the future could hold incredible opportunities.

Since transportation consumes as much energy as electricity generates, some promising developments include biofuels for vehicles, 3D digital maps optimizing fuel-efficient routes, driverless personal and commercial vehicles, and futuris c urban designs with no surface transports on.

Fusion Energy: A Star on Earth?

Andrew Zwicker, a physicist, science educator, and lecturer at Princeton University, presents an inspiring vision in his TED Talk. He discusses the potential of fusion energy—creating a “tiny star” within a fusion reactor. Using rings of super-strong magnetic fields, plasma can be contained safely to produce immense heat. This heat then converts water to steam, generating electricity.

For context, the Sun’s core temperature is 15 million degrees Celsius. Zwicker explains that for hydrogen atoms to fuse in a reactor, we would need to heat it to an astonishing 100 million degrees Celsius.

Is this vision of harnessing fusion energy utopian or practical? Zwicker’s talk and related research reveal the incredible strides being made to turn this once-dreamlike concept into a viable solution.

The Holy Grail of Energy: Thermonuclear Fusion

Thermonuclear fusion, once referred to as the holy grail of energy, is no longer just a distant dream. Aerospace giant Lockheed Mar n is developing a compact 100 MW high-beta fusion reactor that could revolutionize the energy landscape. Measuring roughly 2x2x4 meters, it’s small enough to fit inside a living room. Lockheed aimed to have a working prototype by 2017, capable of continuously powering 100,000 homes.

Fusion energy, unlike nuclear fission, mimics the process of the sun by fusing atoms together rather than splitting them apart. This process promises to provide a safe, virtually endless power source without the risks and waste associated with current nuclear technologies. Lockheed's ambitious plan includes deploying small-scale reactors by 2017 and scaling up to full-size power plants within a decade. By 2050, their ultimate vision is to meet global energy demands with fusion alone, potentially eliminating the need for fossil fuels, nuclear power plants, coal, and natural gas.

A Thriving Fusion Race

Lockheed Martin is not alone in pursuing fusion energy. Several other privately funded startups are making significant progress in this space, including:

While Lockheed's project appears closest to large-scale implements on, the competition on demonstrates the growing interest and investment in fusion as a viable energy solution.

One standout innovation is Magnetic Target Fusion (MTF), led by Michel Laberge and his team at a lab near Vancouver. Their prototype fusion reactor, inspired by the sun’s processes, aims to produce cheap, clean, and abundant energy.

Renewable Energy: A Complementary Path

In addition to fusion, renewable energy sources are shaping the future. Denmark has already demonstrated remarkable success with its integrated CHP energy policy, and Germany has committed to phasing out all nuclear power plants by 2025. Germany’s strategy includes substantial investments in renewable energy—wind, solar, geothermal, and hydro—while developing an industrial model for manufacturing and maintaining renewable energy products.

A critical insight from Germany’s approach is the economic trajectory of energy costs. Fossil fuel costs will continue to rise due to their finite supply, whereas renewable energy costs will decrease over time, driven by economies of scale and technological advancements.

Germany’s Energy Revolution and Lessons for the World

Germany, the wealthiest country in Europe, is renowned for its advanced industries, technology, and a legacy of producing Nobel Laureate scientists, second only to the United States. When Germany decided to phase out its high-risk nuclear power plants, it raised a compelling question: Should other countries reevaluate their energy policies?

While Germany faces challenges such as occasional shortages in base-load electricity due to the fluctuations of renewable energy supplies, its forward-thinking approach is setting the stage for a more sustainable future. With increasing scales of renewable energy integrated into the grid and advancements in smart grid management software, Germany is on track to be a global leader in energy innovation by 2050.

 

Final Thoughts on Climate Change and Energy Policy

This marks the final chapter of my study on climate change and the energy crisis. I hope you’ve found these chapters insightful and enjoyed the wealth of freely shared educational videos on YouTube. I extend my gratitude to the brilliant minds and organizations in climate science and energy sectors whose contributions have enriched this discussion.

Throughout this study, I have expressed my strong opposition to nuclear fission power plants. Economically, they are unsustainable and o en result in significant financial losses—not to men on the astronomical and unpredictable costs of handling spent nuclear fuels. In my view, the primary motivation for some na ons to maintain nuclear power plants is the “disguised” supply of nuclear fuel (plutonium) for military purposes. As long as these plants exist, the threat of nuclear weapons proliferating—and the catastrophic risk it entails—remains a danger to humanity.

The only nuclear energy solution that I believe holds promise for the future is nuclear fusion, which offers a safe and sustainable base-load energy op on. Fusion truly represents the holy grail of energy solutions.

 

A Personal Perspective on Climate Change

I firmly believe that climate change is real and has been significantly driven by industrialization over the past century. To put this into perspective: the likelihood of a plane crash is perhaps 1 in a million, but the probability of the planet experiencing a catastrophic 5-6°C rise in temperature is likely greater than 1 in 100. Such a risk would be unacceptable at a personal level, yet we con nue to tolerate it on a global scale.

Every one must urgently adopt green energy policies, taking cues from trailblazers like Denmark and Germany. Climate change is an existential threat that will devastate humanity if we persist in ignoring the need for action.

No single country can solve this crisis alone. However, with a unified global consensus and the collective will to change, there is a path forward. And I remain hopeful that together, we can overcome this challenge and secure a sustainable future for generations to come.

沈教授會唔會考慮一下搵陳志宏教授講一講科普題目?

KTH

這可分享李偉才博士的訪問

堅離地書院 College

其實啲核廢料係可以用喺熔鹽爐式核裂變反應堆,非常安全。只係因為不明原因無人投放資金喺呢個技術。 Microsoft 已經買起咗美國三里島核電廠,至於 Amazon 同 Google 都爭相買核電公司,投資落去研究微形化反應堆同熔鹽爐技術。核電復興喺大數據同AI 技術推動下已經係不可逆轉既趨勢。

KTH

除了掩埋之外,沒有有效的方法來處理核廢料。任何自然災害,如地震,都會暴露出累積的核廢料,這些廢料將在未來殺死大多數人。因此,如果我們不能處理核廢料,這就不是一種有效的能源生產方式。

Simon S Yam

Nuclear Fusion 發電暫時都仲係一個騙局,前排美國發表過一個所謂成功既 Nuclear Fusion 發電,但佢前提要用非常精確既鐳射,個膠囊又要做到好完美,先至可以產生小小同好短暫既能量增益,但實際在有啲輸入既能量又無計,計埋反而變成負能量增益。 呢個所謂突破只係攞黎嚇窒某大国,引大國投放更多資源,重蹈蘇聯覆轍。 現在既技術,其實反而係核烈變發電技術更安全,比核聚變既假大空更實際更可行。

This essay reminds me of the relationship between science, truth, and facts. Scientific truths, with the exception of mathematical proofs, are inherently provisional rather than relative. They often represent “approximations to the truth.” A scientist's perspective on the truth diverges from popular beliefs. These truths, denoted with a lowercase “t,” are tailored to the specific period, context, facts, reality, and purpose at hand. It might seem unconventional, but scientists frequently utilize the term “error” more than “truth.” However, the “error” mentioned here is not synonymous with “mistake” or “falsehood.” Objective facts are immutable, but how we interpret the truth changes over time as we gain a better and deeper understanding of a problem.

1) A few environmental issues are mentioned (biodiversity, pollution etc) Climate change is just one of them. 2) Energy generation is just one of the aspects contributing to “both” i) climate change and ii) damage to our biosphere. Making things (cement, steel, plastic etc) all require fossil fuels. So does agriculture. 3) Regardless of the view whether climate change is an existential crisis, what is clear is that net-zero by 2050 is a “very” ambitious target (in all probability an understatement). Achieving this goal requires many technologies and industrial processes that doesn’t exist yet. Try looking at the economics of the alternatives you will see how practical they actually are. 4) We will be stuck with fossil fuels for a very long time. We don’t have a method of producing cement that doesn’t require burning fossil fuels for example (nor do we have one for steel making, plastics or fertilisers, all foundations of our civilisation), let alone commercialising these at multi-trillion dollar scale in a short timeframe. We have not begun talking about supporting infrastructure. 5) On climate change, realistically “both” mitigation and adaptation are required. Mitigation requires not one innovation but many different innovations in different industries. And our technological progress outside of digital technologies have been rather slow in comparison. A transformer now still looks like a transformer 50 years ago. And unlike inventing a new drug for treating diabetes, many green innovations will not happen by themselves without government intervention (we are talking about green premiums, not green discounts. People will want a particular brand of car, but no one will ask for a particular flavour of electricity). And there are many poor governments as well as rich governments with tight budgets. 6) That doesn’t answer the infinite resource proposition, but to me that is irrelevant. It doesn’t matter if you substitute wood with copper, copper with iron, iron with steel etc. There is only one biosphere, we should not harvest beyond the capacity of the biosphere to regenerate, while compromising its ability to regenerate at the same time. To build a new reactor, you still need steel and cement. Anyone who bother doing the math, it should give a pretty sobering view on what lies ahead. No growth in complex systems continue indefinitely. Irrespective of the probabilities of catastrophes, our best course of action as a species is to live within sensible means.
