Human activities significantly contribute to climate change by causing changes in the earth’s atmosphere in the amount of cloudiness, aerosols, and greenhouse gases. The largest known human contribution comes from the burning of fossil fuels, which results in releasing carbon dioxide gas to the atmosphere (Colleen & Maier, 2019). Greenhouse gases and aerosols have adverse effects on the climate, where they alter the incoming solar radiation and outgoing infrared radiation, which are a part of the earth’s energy balance.
Changing the atmospheric abundance or properties of these gases and particles can result in a warming or cooling of the climate system. Since the beginning of the industrial era, (1750), numerous activities have affected the climate and have had a warming influence. During this era, the human impact on climate change was massive due to the known changes in the natural processes, including volcanic eruptions and solar changes (Colleen & Maier, 2019). Some of the four principal greenhouse gases that are a result of human activities include carbon dioxide (CO2), the halocarbons, nitrous oxide (N2O), and methane (CH4). The gases accumulate in the atmosphere, leading to high concentrations that consequently lead to climate change.
Other human-driven changes include land use, such as urbanization, deforestation, and also shifts in vegetation patterns. These activities result in changes to the reflectivity of the earth’s surface. Other activities by humans on land include emissions from the burning of forests, urban heat island effects, and the natural water cycle changes.
Reducing the Risk of Global Climate Change
Some of the changes may include improving energy efficiencies, such as increasing wind and solar power, and biofuels from organic waste. There is also a need for people to invest in green energy, such as wind and solar, great renewable energy options. Investing in energy-efficient appliances can also minimize the amount of carbon dioxide and other air emissions. Saving water reduces carbon pollution (Denchak, 2017). There will also be a need for humans to consider saving water as a way of saving the energy used to pump, heat, or even treating the water. This may include taking shorter showers, turning off the tap water, and using appliances to minimize water usage.
Protecting the forest will also be a vital step to undertake to help in tackling climate change since it will help in reducing the amount of carbon dioxide and other gasses that trap the heat on the planet. Raising awareness is another critical measure that can be taken to ensure that humans protect their environment from climate change. This includes voicing concerns through various platforms on behavioral change and the need to protect the world against global warming. There is also a need to pressure the policy makers to enact laws that will limit carbon emissions and require the polluters to pay for their emissions.
It is evident that the primary cause of the recent global climate change is that the solutions are also within the human domain. There is a need to fully understand the causes of climate change, paving the way for practical solutions to be developed or deployed. Addressing climate change will require several solutions, ranging from behavioral changes to policies which encourage less waste and smart use of the resources in place.
