Al Gore, the former American vice president, once drew a stark contrast between the extinction of dinosaurs due to a giant asteroid 65 million years ago and the ongoing species extinctions happening in the present. Gore asserted that the latter is not merely a result of natural havoc but is intricately linked to human activities. This essay delves into the dynamics of climate change, dissecting the dual influences of natural causes and human activities, particularly examining the escalating impact of the latter on our environment since the industrial revolution.
Climate, defined as the average weather influenced by gradual factors such as oceans, precipitation, and clouds, is subject to two primary causes of climatic alterations.
One of these causes is natural, encompassing phenomena like forest fires and volcanic eruptions. While these events release vast amounts of pollutants into the atmosphere, they are also instrumental in maintaining the delicate balance of our planet.
Volcanic eruptions, such as El Chichon in Mexico (1982) and Mount Pinatubo in the Philippines (1991), exemplify the dual nature of natural causes.

These eruptions not only release pollutants but also contribute to the depletion of the ozone layer. Despite their significant impact, natural causes, including volcanic emissions and the decay of organic materials, have operated within the earth's natural balance for millions of years.
Contrary to the cyclical nature of natural causes, human activities emerge as the primary driver of contemporary climate change, especially since the industrial revolution. Analogous to nature, humans release gases, particularly carbon dioxide (CO2), into the atmosphere.
Noteworthy examples of these activities include the combustion of fossil fuels and emissions from factories and automobiles.
While the emission figures for CO2 from the ocean and vegetation are substantial, ranging from 332 to 439, these natural processes simultaneously absorb a comparable amount of CO2. In contrast, human activities, such as burning fossil fuels and land use changes, release a relatively minimal amount of 29 into the atmosphere. Despite this seemingly small contribution, the crucial distinction lies in the ongoing and one-way nature of human-made emissions.
The crux of the issue lies in the irreversibility of human-made contributions to climate change. Unlike natural causes that operate in cycles and contribute to maintaining atmospheric equilibrium, human activities represent a continuous and unidirectional process. Harmful gases are released into the air without corresponding efforts to mitigate or dissolve them, leading to an imbalance in the Earth's climate.
This one-way trajectory, primarily characterized by the burning of fossil fuels, has far-reaching consequences. Human actions are not only causing extreme weather conditions but are also driving a phenomenon that has garnered significant attention – global warming.
Global warming, the gradual increase in the Earth's average temperature, emerges as a direct consequence of human activities, particularly the combustion of fossil fuels. As small particles released into the air alter the energy absorption and reflection capacities of the atmosphere, studies indicate that their primary goal might not be to cool the Earth but rather to intensify temperatures.
Another pivotal factor in Earth's climate adjustment is the greenhouse effect, characterized by the trapping of sunlight by greenhouse gases like CO2, Chlorofluorocarbons (CFCs), and Methane (CH4). While these processes occur naturally, human interventions have dramatically accelerated them, exacerbating the impact on our climate.
The repercussions of climate change, largely propelled by human industrialization, manifest in the melting of ice caps and shifts in weather patterns. Contrary to arguments suggesting a natural state of climate flux, the evidence overwhelmingly points to human activities as the driving force behind these environmental transformations.
The Earth, in its natural state, undergoes climate adjustments through processes like the greenhouse effect. However, human interventions have not only accelerated these processes but have introduced numerous complications into the delicate balance that sustains our planet.
In conclusion, climate change unfolds through two primary causes: natural processes and human-made contributions. While natural causes play a role within the earth's capacity to balance climate, it is the ongoing and unidirectional procedures of human activities that escalate the imbalance, resulting in severe complications like global warming and the greenhouse effect.
This isn't a challenge that can be easily overcome in a few short years or with isolated solutions. Instead, it is a global problem demanding collective effort. The responsibility for the well-being of our world lies in the hands of each individual, and the choices we make today will determine the legacy we leave for future generations.
