We Know the Climate is Changing Rapidly: But What is the True Cause?
Climate change is a topic of constant debate. We hear about rising temperatures, melting glaciers, and extreme weather patterns almost daily. But here’s the real question: is climate change primarily caused by human activity, or could other forces be at play? While the prevailing scientific consensus is that human actions are the main driver, there are alternate perspectives that deserve our attention. Or, as I concluded, the leading climate change is the result of Human Prosperity.
This post will explore both sides of the debate, giving you a clearer view of the factors contributing to our changing climate.
Human Activity: The Main Culprit?
The prevailing consensus is that human activity, mainly since the Industrial Revolution, is the primary cause of climate change. The main pieces of evidence for this are:
CO2 Levels and Temperature Rise: Carbon dioxide levels have increased from 280 parts per million (ppm) in 1850 to over 400 ppm today. This increase coincides closely with industrial activity and the burning of fossil fuels. The connection between human-produced CO2 and rising temperatures seems undeniable.
Scientific Consensus: About 99% of peer-reviewed scientific studies agree that climate change is predominantly human-driven. This consensus comes from decades of data and computer modeling that show how CO2, methane, and other greenhouse gases trap heat in the Earth’s atmosphere.
Computer Models: Climate models, which attempt to replicate Earth’s climate systems, show that natural factors alone cannot explain the current warming trend. The models only match the observed temperature rise when human emissions are included, highlighting our significant role in global warming.

Key Human Contributions to Climate Change
Oceans: The oceans absorb much of the planet’s heat and carbon dioxide. Warming waters lead to thermal expansion, contributing to rising sea levels and changes in ocean chemistry, such as acidification, which impacts marine life.
Burning Fossil Fuels: Power generation, transportation, and industrial processes all require massive amounts of coal, oil, and gas. Burning these fuels releases carbon dioxide and other gases that contribute to the greenhouse effect.
Deforestation: Forests are nature’s carbon sinks, absorbing CO2 from the atmosphere. Cutting them down reduces this capacity while releasing the stored carbon, contributing about 10% of all warming emissions.
Agriculture: Methane emissions from livestock and nitrous oxide from fertilizer use are also significant contributors.
These factors, combined with urbanization and changing land use, have pushed greenhouse gas levels to heights not seen in hundreds of thousands of years, resulting in the accelerated warming we see today.
Dr. Willie Soon’s Perspective: Is it the Sun?
Dr. Willie Soon’s work also examines the relationship between climate change and energy policy and the shortcomings of current approaches to renewable energy. He argues that the push towards green energy, such as solar and wind, may not be as effective or environmentally beneficial as often claimed.
Decoupling Climate Change from Energy Policy: Dr. Soon stresses that energy policy must be addressed independently of climate concerns. He highlights that using high-energy density resources like coal, oil, and nuclear energy has historically been the foundation for societal progress and should not be hastily discarded.
Critique of Green Energy: Soon argues that solar and wind energy require more resources than fossil fuels. For example, to replace just a small portion of fossil fuel-powered cars with electric vehicles would require a massive increase in the extraction of minerals such as cobalt and lithium. Solar and wind farms also require significantly larger land areas, potentially harming biodiversity and natural habitats.
Chesterton’s Fence Analogy: Dr. Soon uses Chesterton’s Fence analogy to argue that drastic changes to our energy infrastructure should not be made without fully understanding their implications. He emphasizes that the concept of “clean energy” is misleading, as all forms of energy generation have costs and trade-offs.

Other Perspectives on Climate Change
In addition to Dr. Soon’s arguments, other important critiques focus on the structure and operation of climate science institutions like the IPCC:
The Role of the IPCC: Dr. Soon is critical of the IPCC’s role in promoting a “consensus-driven” approach to climate science. He points out that the IPCC’s primary aim is to support policy decisions, which can sometimes lead to oversimplification or even suppression of dissenting research. According to Soon, the IPCC often downplays or ignores studies that do not align with their narrative, which he claims distorts public understanding of climate science.
Urbanization Bias: Soon also raises concerns about the urbanization bias inherent in many climate models. Urban areas tend to be warmer due to the “urban heat island” effect, and since many weather stations are located in these areas, this could skew global temperature readings upward. He suggests that current temperature estimates overstate the extent of warming due to this bias.
While Dr. Willie Soon offers a different view on the main drivers of climate change, he is not alone. Several other scientists present perspectives that challenge the mainstream consensus:
- Myron Ebell: Director of energy and global warming policy at the Competitive Enterprise Institute, Ebell argues that skepticism on climate change needs to be unified. He points out that many skeptics focus on questioning the certainty of climate models and the overemphasis on CO2 as the sole driver of climate change. He believes other natural variables could also play significant roles, often overlooked in mainstream climate discussions.
- Richard Lindzen: An atmospheric physicist from MIT, Lindzen has questioned the extent of human influence on recent warming. He argues that the complexity of the climate system and the natural variability observed throughout Earth’s history make it difficult to attribute all recent changes solely to CO2. According to Lindzen, past climatic changes, which occurred without human intervention, should make us more cautious about our conclusions.
- Bob Carter: An environmental scientist from James Cook University, Carter emphasizes historical climatic shifts like the Medieval Warm Period and Little Ice Age. He suggests that these periods indicate that modern changes could be part of a natural cycle rather than being driven by human activity. In a New York Post article, Carter stated: “Science is never settled, but the current state of ‘climate change’ science is quite clear: There is essentially zero evidence that carbon dioxide from human activities is causing catastrophic climate change.” — Tom Harris and Bob Carter, New York Post.
- Henrik Svensmark: Svensmark, a Danish National Space Center physicist, proposes that cosmic rays may play a role in cloud formation and thus influence Earth’s temperature. He suggests that variations in solar activity could impact the number of cosmic rays reaching Earth, affecting cloud cover and global temperatures.

These perspectives add depth to the debate and remind us that climate change is a complex issue with many factors at play.
While human-driven climate change is the dominant narrative, not everyone agrees. Dr. Willie Soon, an astrophysicist and geoscientist, offers an alternative perspective. According to him, the primary driver of Earth’s changing climate is not CO2 but solar activity.
Dr. Soon argues that changes in the Sun’s magnetic field, solar radiation, and even Earth’s orbital variations have far more significant influence on the climate than human actions. Here are some of the key points he brings up:
Solar Influence: The Sun’s radiation varies over time due to changes in its magnetic field and sunspot cycles. These variations can significantly impact Earth’s climate. For example, periods like the Little Ice Age (roughly from the 14th to the 19th century) saw decreased solar activity, coinciding with much cooler global temperatures.
Planetary Orbits: Earth’s orbit changes slightly over long periods, affecting the amount of sunlight different parts of the Earth receive. According to Dr. Soon, these subtle changes, combined with variations in solar radiation, account for much of the warming and cooling we observe.
Abiogenic Hydrocarbons: Dr. Soon also challenges the traditional view that oil and natural gas are entirely derived from ancient organic matter. He points out that complex hydrocarbons have been found on planets and moons in our solar system that have never had life, suggesting a more geologic origin for these substances. This raises questions about the finite nature of fossil fuels and their relationship to the climate.
Skepticism of CO2 as a Main Driver: Dr. Soon must be more convincing that CO2 levels are as influential as often portrayed. He claims that the rise in CO2 is not capable of causing the changes we see in climate patterns. Instead, he views CO2 as a “gas of life” that enhances plant growth and contributes positively to the biosphere.
The Debate Over Scientific Consensus
One of Dr. Soon’s most prominent criticisms of mainstream climate science is the reliance on models that, in his view, oversimplify complex systems. He believes that while the models are well-intentioned, they cannot fully capture the intricacies of solar activity, ocean currents, and other natural phenomena. He also raises concerns about the funding and biases within climate science, suggesting that pressure to align with government policies could impact the objectivity of research.
This perspective highlights an important point: science is not just about consensus but about questioning and testing prevailing ideas. In Dr. Soon’s view, the role of the Sun is undervalued, and the impact of CO2 is overestimated.
Are There Other Factors at Play?
- Energy Policy and Its Impact: Soon emphasizes that modern energy policies that reduce CO2 emissions often overlook broader environmental and societal costs. For example, renewable energy technologies like wind and solar have substantial ecological impacts due to the need for extensive land areas and increased mineral extraction. He argues that the current emphasis on these technologies may lead to unintended consequences such as energy poverty and ecological harm.
While the discussion often centers on CO2 and solar radiation, other natural factors could be influencing climate change:
Volcanic Activity: Major volcanic eruptions eject large amounts of ash and gases into the atmosphere, which can temporarily cool the planet by reflecting sunlight away. Though this effect is typically short-term, it does demonstrate the impact natural events can have on global temperatures.
Ocean Currents: The oceans act as huge heat sinks and are critical in regulating Earth’s climate. Changes in currents, such as those caused by El Niño and La Niña events, can substantially affect global temperatures and weather patterns.
Cosmic Rays and Cloud Formation: Some theories suggest that cosmic rays—high-energy particles from space—could influence cloud formation, thus affecting Earth’s climate. A cloudier Earth would reflect more sunlight, leading to a cooling effect. This is still a developing area of research, but it’s another factor worth considering.
Open Minds, Better Solutions
The truth is the climate system is incredibly complex. Most scientists agree that human actions are a major driver of climate change, but that doesn’t mean we should ignore other possibilities. The perspectives of researchers like Dr. Soon remind us that nature has many intricacies we are still learning about. Solar influences, ocean currents, volcanic eruptions, and even cosmic factors all play roles in shaping the Earth’s climate.
Whether you align more with the mainstream perspective or are intrigued by alternate views, one thing is clear: our climate is changing. We need more research, more open discussion, and a willingness to adapt our approaches based on new information. While reducing emissions is undoubtedly essential, understanding the broader picture—including all possible natural influences—can help us make more informed decisions.
Where Do We Go From Here?
Balanced Policies: Rather than focusing solely on reducing carbon emissions, policies should consider the multifaceted nature of climate drivers. This includes investing in renewable energy and researching nuclear power, carbon capture, and storage technologies.
Scientific Transparency: Climate science needs more transparency and a willingness to challenge existing models and ideas. Public access to climate data and clear communication of uncertainties will foster better trust and understanding.
Adapting and Innovating: Regardless of the cause, our climate is changing. Focusing on adaptation strategies, like improving and optimizing existing infrastructure rather than expanding at the cost of natural habitats and deforestation, affects wildlife. Conservation of our natural habitat is vital to maintaining biodiversity and ecological balance and can reduce the impact of climate change on society. Innovation in energy, agriculture, and construction will also play a vital role. We should also champion initiatives and investments in clean air, water, and soil and create more green spaces where humans and nature can coexist harmoniously.
Conclusion: A Call for Critical Thinking
The climate debate is complex and full of nuance. While most scientists point to human activity as the primary cause of recent changes, alternative views like Dr. Soon suggest we may still need to understand everything. We owe it to ourselves and future generations to consider all perspectives, encourage open debate, and base our decisions on a comprehensive understanding of all the forces at play.
As we move forward, let’s remain open to new evidence, critical in our thinking, and collaborative in our solutions. Our planet’s future depends on it.
