Global warming, which has been caused by the increase in the concentration of greenhouse gases in the atmosphere, is affecting our world to a very large extent and in numerous ways. Knowledge of drivers of climate change impact is crucial in the development of efficient adaptation and mitigation processes. The article provides an overview of the most common causes of climate change, taking into account both the natural and anthropogenic causes of the global process.
Let’s understand the factors causing climate change impact
- Greenhouse Gas Emissions:
The root cause of the effect of climate change is the release of greenhouse gases (GHGs) into the environment. The GHGs are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases, which trap heat and heat the Earth. Burning fossil fuels (coal, oil, and natural gas) to produce electricity, fuel motor vehicles, and fuel industrial processes is the largest source of CO2 emission. Agriculture, deforestation, and industry also release the largest quantities.
- Burning of Fossil Fuels:
Fossil fuel burning is the largest GHG polluter and worst air contaminant of the climate change impact. Burning, processing, and refining coal, oil, and natural gas release vast amounts of CO2 into the environment, mainly causing the heating of the earth worldwide. Fossil fuels are used extensively to move commodities and human beings in the transportation industry, powering, and for industrial purposes, hence the leading culprits of climate change.
- Land Use Change and Deforestation:
Cutting down trees, or deforestation, for the purpose of utilizing them for some purpose such as farming, urbanization, and for wood is the second largest reason for the effect of global warming. Photosynthesis is formed in a way to uptake CO2 present in the atmosphere, and when forests are cut, carbon bound up in forests is released into the atmosphere. Deforestation also impairs the planet’s capacity to sequester CO2 and thereby causes climate change. Land use change, urbanization, and agriculture are some of the other reasons for GHG emissions.
- Industrial Processes
Certain industrial processes release enormous amounts of greenhouse gases that are the cause of climate change impacts. Manufacturing of cement, for example, releases enormous amounts of CO2. Certain industrial processes such as manufacturing chemicals and refrigerants release very potent greenhouse gases such as methane and fluorinated gases with much higher global warming potential than CO2.
- Agricultural Practices
It is agricultural activities that account for the climate change impact via a number of pathways.
Livestock, particularly grazing by cattle, is also one of the main sources of methane. The second powerful greenhouse gas with a good amount of climatic effect discharged through use of fertilizer during cultivation is nitrous oxide. Carbon emission and also sequestration by land soil has the ability to do the same from agriculture land use as well. 6. Natural Factors:
Even though human activities impose the largest burden of current climate change, there are naturally occurring processes that affect the Earth’s climate. Volcanic eruptions emit huge amounts of gases and air-borne aerosols and, within a very short time scale, cool the Earth. Solar variability in terms of changes in solar radiation contributes less than infinitesimal amounts to the climate. However, the trend of warming that has been observed is largely anthropogenic GHG emission because the dramatic global rise in temperature cannot be explained by natural forcing.
- Feedback Loops
Global warming might introduce a few feedback loops, whose tendency might be to facilitate or damp the original warming. Thawing of Arctic sea ice and permafrost would tend to enhance warming by creating positive feedback loops. Melting of ice would lead to a greater number of dark-colored surface areas of highly absorbing capacity ocean surfaces for sun radiations with a tendency to enhance warming. Methane release, a very powerful greenhouse gas, from thawing of permafrost further enhances global warming.
- Global Warming Potential
Varying greenhouse gases have varying global warming potential (GWP). GWP describes the relative amount of heat trapped in a greenhouse gas in relation to CO2 over certain numbers of years. Methane, for instance, possesses greatly higher GWP in relation to CO2 in 20 years and consequently traps far more heat. To possess GWPs is beneficial in designing effective mitigation policy and channeling action to eliminating best-effect greenhouse gases.
- Interconnectedness of the Factors:
Causative-interaction among causes of climate change are interwoven through their presence and co-exist in a recursive process. Deforestation yields CO2 as a by-product, while decreasing carbon is impaired because sequestrative capabilities decrease. Production agriculture involves methane and nitrous oxide emissions. The interwritings should be conceived in a vision to pursue a comprehensive set of affirmative actions under climate regime management.
- Variability of Regional Effect
They are unevenly distributed globally. It does contain pockets of outstanding vulnerabilities to outstanding impacts, such as sea-level rise, drought, or meteorological disasters. Regional vulnerabilities are the base upon which adaptation planning needs to take place and upon which the most vulnerable receive help.
- The Imperative of Action
Scientific perspective is one: global warming exists, it is occurring today, and it is man-made. The earlier we shift not to wait for the GHG emissions, the lesser and reversible will be the effect of global warming. Radical steps and a leap, but let us shift low-carbon. today so that our future generation can live comfortably on our planet.
- Mitigation and Adaptation Plans
There has to be an adaptation and mitigation plan with two tracks to climate change in adaptation and mitigation. Mitigation is GHG emissions reduction by alternative energy, energy efficiency, and sustainable land use. Adaptation is acclimatization to unavoidable effects of climate change, i.e., sea-level rise and weather extremes, through building resilience and safeguarding vulnerable groups.
- Individual and Business Action
Humans and economic actors are the primary agents to be tackled by the issue of climate change. Human beings can lower their carbon footprints by utilizing green lifestyle options, i.e., clean transportation, energy-saving options, and plant-based foods. Businesses can green themselves, invest in renewable energy, and promote climate-friendly policies.
- International Cooperation and Policy
International cooperation and sound policymaking are required to address the issue of climate change. International policy like the Paris Agreement offers an example that countries can use for climate change adaptation and mitigation. National and subnational policy responses are as applicable for adaptation as they are for effective mitigation. Causes of the impacts of climate change are usually interacting and multidirectional and anthropogenically induced primarily, made up of fossil fuel use. Knowledge of these reasons, including the role of greenhouse gases, deforestation, industry, and natural factors, is essential in devising an appropriate solution. Preventing climate change by reducing emissions and adjusting to its irreversible consequences is necessary with immediate action. It needs to be tackled by all of the individuals, companies, governments, and global communities by the collaborative efforts to end the world issue and have a better future for everyone.
