Industrialization and other human activities have led to economic development and civilization. People have come up with innovative ways to use natural resources to fulfill their needs. However, the use of fossil fuel, deforestation, inappropriate waste disposal, mining activities, and over-exploitation of natural resources has taken a toll on the environment. That has led to adverse effects. This paper aims at explaining what global warming is, its effects, and how to control it.

Global warming is a phenomenon of climate change. It is characterized by a steady increase in the average global temperature over a long time (NRDC, 2016). It is a result of environmental pollution due to different human activities. According to NASA, the increase in temperature occurs when large amounts of various air pollutants, Carbon II Oxide, and greenhouse gases accumulate in the atmosphere. They absorb the solar radiation and sunlight that bounces off the surface of the earth and traps the heat within the continent. That interferes with the ecosystem and weather balance and worsens the “greenhouse effect” (NASA, 2019). The gases that cause pollution are semi-permanent (NRDC, 2016). That makes it a life-long problem.
The effects of climate change are significant enough to affect both human and animal health directly and indirectly (Kim, K et al., 2014). However, we are yet to experience more of these effects. The change will affect various continents in different ways, and developing countries will be truck severely (UNEP, 2019). Continents and oceans show that natural systems are being affected by an increase in temperature (IPCC, 2007). Scientists claim that recent extreme weather changes are some effects of the change in the climate. That includes frequent drought, destructive hurricanes, intense heat waves, and rising sea levels leading to coastal flooding (The Union of Concerned Scientists, 2019). Besides the environmental damage, global warming also affects human health. A deterioration in the quality of air will lead to cardiovascular and respiratory health problems (The United States Environmental Protection Agency, 2017). It might affect food production in other regions, leading to food insecurity and malnutrition. Stagnant water during floods will also lead to an increase in insect and waterborne diseases (US Global Change Research Program, 2016).
It is not easy to reverse the effects of climate change. It might take decades to restore the environment to its original state. Scientists claim that controlling greenhouse gases will help curb the impact of climate change (Union of Concerned Scientists, 2011). Countries need to work together to implement appropriate policies to avoid further change (NRDC, 2011). That is by planting trees, using clean energy, reducing water wastage and pollution, and embracing energy efficient lifestyles (NRDC, 2017). World leaders are taking action to mitigate environmental damage. For example, the former US president, Barack Obama, started the National Climate Action Plan to reduce the emission of harmful gases (UCS, 2019).
Research shows that the average global temperature is going to keep increasing until people take action against environmental pollution. Educating people about the effects of climate change is the best way to encourage them to embrace environmental conservation programs. People in different climatic zones will feel the impact of global warming in different ways. The survival of future generations depends on the actions taken today. Therefore, different nations need to work together to prevent further damage (UNEP, 2019).
