Causes and Mitigation of Climate Change

Addressing climate change is challenging, with political and economic obstacles making reducing greenhouse gas emissions complex. Since the potential benefits of mitigating climate change are immense, all individuals globally should take necessary measures to avert the worst impacts of climate change and create a more sustainable future for all. Since the middle of the 20th century, human activity has been responsible for changes in the Earth’s climate. Burning fossil fuels, in particular, has increased the amount of heat-trapping greenhouse gases in the atmosphere, which has raised the planet’s average surface temperature. Greenhouse gases include high levels of carbon dioxide in the atmosphere and other harmful gases such as nitrous oxide, methane, and halocarbons that trap thermal heat in the atmosphere, causing global warming. This relates to a recent article by Muhammad Kabir et al., in which the authors undergo the effects of rising carbon dioxide levels on our climate and the environment. Muhammad Kabir et al., all of whom are students of Natural and Environmental Sciences in Pakistan and Chile, undergo the effects of rising carbon dioxide levels on our climate and the environment. In 2017, around 35.8 Gt CO2/year was emitted into the air, which is projected to increase by 2.6% in 2018. Deforestation is also viewed as a human activity that causes global warming. Collins et al., who are all researchers in physical sciences, including astrology, atmospheric science, astrophysics, and astronomy in various universities in the US, explain that deforestation leads to the release of carbon dioxide and other greenhouses into the atmosphere (65). According to the United Nations Climate Change Commission, Pakistan is one of the top ten nations most threatened or vulnerable to climate change. According to scientific and technological predictions, the Earth’s average temperature will increase from 2.5 to 4.5 in the twenty-first century. The Pakistan Meteorological Department reports that February 2021 was one of the hottest and driest in Pakistan’s history (Muhammad Kabir et al). In other words, the frequency of global warming has significantly increased, disrupting the global ecosystem.

Furthermore, elements of industrialization, such as intensive industrial and agricultural processes that emit greenhouse gases as waste to the atmosphere and urbanization, have caused increased temperatures and changes in weather patterns. Industrialization produces harmful gases to the environment, while urbanization removes protective factors such as vegetation, which otherwise purifies the atmosphere by absorbing and cleaning CO2 from the environment (Kabir et al. 2). In addition, building and construction are also aspects of urbanization that significantly contribute to atmospheric pollution and, thus, climate change. Kessler, a doctorate student in Business Administration at the University of Pennsylvania, explains that the construction process pollutes the environment through evacuation, mining, transportation of building materials, and manufacturing, which constitutes embedded emissions (2). Moreover, structures cause CO2 emissions to the atmosphere from energy used for activities such as heating, lights, receptacles, cooling, and industrial load processes. Apart from the above causes, Abbas et al., all of whom are researchers in media, economics, and environmental sciences, various universities in China, Saudi Arabia, and Bangladesh state that “other anthropogenic activities include excessive agricultural operations, which further involve the high use of fuel-based mechanization, burning of agricultural residues and deforestation” (2). Excessive agricultural operations such as mechanization, burning agrarian residues, and deforestation increase greenhouse gas emissions, worsening climate change. Therefore, the causes of climate change are mainly excessive human activities that emit greenhouse gases into the atmosphere, causing heat-trapping and global warming, whose ripple effects affect agents of weather such as temperature, precipitation, humidity, and pressure.

The anthropogenic causes of climate change outlined above continue to escalate wide-ranging consequences on human life. Some of the effects of human activities on climate include extreme weather events that considerably impact agricultural production. Awazi, a researcher and lecturer at the Department of Forestry and Wildlife Technology from the University of Dschang in Cameroon, explains that hurricanes, cyclones, floods, droughts, bushfires, and pests are the frequent consequences of climate change (1). Awazi notes that these extreme weather events significantly affect agriculture, which depends on climate. Due to unpredictable climactic changes, farmers find it increasingly difficult to continue their agricultural routines. As a result, farmers are resorting to agroecological practices such as agroforestry. Climate change can have devastating implications in countries that rely on agriculture as the backbone of the economy.

In addition to the effects on agricultural production, climate change also leads to health implications. The extreme weather events caused by global warming and the causes of climate change, including greenhouse gases, multiply the risk of illnesses. Mickel, a Postdoctoral Researcher at Vanderbilt University in Nashville, Tennessee, explains that extreme weather events, including heat waves, bad air quality, storms, floods, droughts, and wildfires increase the risk for illnesses (). The researcher notes that respiratory infections, malnutrition, food and water-borne diseases, and heat strokes are some of the conditions caused by extreme weather events resulting from climate change. Mickel also reports that wildfire smoke contains particulate matter and poisonous chemicals that cause respiratory diseases. In addition, floods have led to increased mosquitoes, which spread vector-borne illnesses. Vectors are sensitive to changes in climate, and their biting rates tend to multiply when temperatures rise and during certain levels of humidity. Pathogenic transmission also occurs at a faster rate during higher temperatures. As such, these aspects underscore the need to mitigate climate change to promote environmental and human health and well-being.


Tackling climate change to mitigate its impacts on public health requires community-level leadership because climate change is fundamentally experienced at the local level. Local authorities can, therefore, use their closeness to the people and improve their quality of life through climate change mitigation. Dam et al., who are leading credible experts studying for their graduate degrees in Health Science at Monash University in Melbourne, Australia, emphasize the need for coordinated local actions in tackling global climate change (2). The scholars stress the central role of local governments in developing policy, mobilizing resources and research to tackle climate change and its health impacts. Dam et al. however, state that: “local governments face numerous challenges in developing local climate policy, including a lack of leadership or political will from higher levels of government, limited resources, institutional constraints, and availability and access to research.

In addition to a local-level approach to climate change mitigation to promote public health, it is essential to mitigate the climate change implications on agricultural production. Agroforestry is one way of mitigating climate change to shield the human population from its adverse effects on agriculture. Awazi, in his article exploring ways of achieving agricultural sustainability in the context of climate change, emphasizes the value of agroforestry in minimizing the effects of climate change in smallerholder farms (1). The scholar explains that agroforestry reduces erosion by providing a cover that reduces the impact of raindrops on the soil as well as contributing to soil fertility through decomposition of organic matter. In addition, agroforestry modifies the microclimate enabling crops that are vulnerable to drought to thrive as well as providing shade. Moreover, agroforestry helps in retention of soil water, which enables crops to thrive during extreme droughts. Agroforestry therefore improves agricultural sustainability through mitigation of the impacts of climate change on agriculture.

However, reducing the greenhouse emissions can be a more sustainable mitigation measure for climate change. Reducing the amount of greenhouse gas emissions can minimize global warming and minimize extreme weather events caused by global warming. Reducing greenhouse gas emissions should, however prioritize areas or activities that contribute significant percentages of greenhouse gas emissions. Kessler, in her article exploring the contribution of buildings to greenhouse gas emissions, states that climate change mitigation should focus on reducing the 40% of carbon dioxide that buildings contribute as a result of energy uses for operations such as manufacturing, mining, transportation and hydroelectric power use (2). The scholar suggests that keeping existing buildings as opposed to tearing them down will help to reduce the amount of carbon released to the atmosphere. The rationale behind this suggestion is that buildings have a significant amount of embodied carbon, and tearing them down necessitates building others, which further adds carbon to the atmosphere.

However, climate change mitigation at the global level tends to be characterized by blame game. Densely populated countries are blamed for climate change, yet, realistically, some developed nations with lower populations contribute much more greenhouse gas emissions than densely populated countries. Rosling, in his book, Factfulness, discuss this blame game and states that blame game is meant to locate the causes of the climate change (213). In addition, Rosling views the blame game in climate change discourse as a demonstration of personal taste. This aspect means that some countries show hesitancy in switching to renewable energy as a way of minimizing greenhouse gas emissions for fear of the economic consequences that would follow such action. Instead of blame game, there is a need to show shared responsibility to reduce greenhouse gas emissions and mitigate climate change to ameliorate the adverse effects it has on the life of species on the planet.


Overall, climate change is a significant global risk with adverse effects on the environment and human life. Human or anthropogenic activities are the leading cause of climate change because these activities contribute to the emission of greenhouse gases, which are the chief causes of climate change. Some of the human activities that contribute to greenhouse gas emissions include industrial activities such as urbanization, agricultural activities, building and construction, and transportation. These activities release harmful gases into the atmosphere, leading to increased temperatures and changes in weather patterns. Climate change leads to extreme weather events which disrupt agricultural routines in smallholder farms, forcing farmers to opt for agroforestry practices. In addition, climate change presents a public health challenge as it increases the risks for illnesses. However, these effects can be mitigated by adopting a local approach to help local communities address climate change effects. Local governments have a fundamental role to play in developing policy and mobilizing resources through evidence-based and coordinated approaches to create local positive impacts and improve the well-being of communities and environments. Agroforestry can be used to improve agricultural sustainability through improved water retention, moderation of microclimates and reduction of soil erosion. However, minimizing greenhouse gas emissions by focusing on key contributors such as building and construction is a more sustainable mitigation measure. It is also essential for countries to embrace shared responsibility in climate change mitigation as opposed to blame game.
