Global Warming Human Causes Essay
Congratulate yourself for wanting to learn more about the main cause of global warming. Not only does our species create huge problems that are beyond the ability of other animals to create, but we have the fortunate ability to analyze them and work to bring an end to their consequences. You are now actively engaged in that process!
Humans cause global warming with our unique ability to capture and use energy from stored energy sources. No other animal can start fires or build gasoline engines.
Consider your home and the environment in which it is situated. The very fact that you live in one place, something that was quite uncommon before the discovery of stored energy sources like fossil fuels, speaks to how your life is facilitated by these unique energy sources.
Even your basic needs are dependent on fossil fuels. Your water, food, and fuel for heating and cooking likely travel hundreds if not thousands of miles to your home.
This pattern couldn’t be sustained if humans didn’t have the ability to exploit dense energy sources such as coal, oil, and natural gas. However, their discovery transformed the face of the earth and the nature of humans.
The effects on earth are dangerous. In the last 150 years, the human population has grown by more than five times and the average person uses more energy than ever. This energy comes largely from fossil fuels, the use of which is a direct and important cause of global warming.
Global Warming is a Growing Problem
The growth of the human population and the growth of consumption adds up to an ever-escalating carbon output. You’ve probably heard a lot of talk about global warming, but if we want to decrease global warming, then the amount of carbon released each year by humans must be drastically reduced.
Human Consumption or Human Population?
Two factors are acting as catalysts of increased carbon levels in our atmosphere:
- Increasing consumption among the wealthy (that means you!)
- Increasing population among the poor
You may wonder which is the primary culprit. The answer is clear – both! Consider the following:
- Americans consume 300 – 600 times as much as people in very poor nations, in some cases.
- 70 million people are added to the world’s population each year, many of whom aspire to live “better” lives, to consume like wealthy people.
From this it becomes clear why humans are the main cause of global warming. However, it is even more important for you to understand that you have the power to help prevent global warming from getting worse — live The Green Life.

Show MoreNowadays, global warming is a term that is widely used by everyone; however most people do not know what it means. Global warming is a phenomenon for which the average temperature of the earth’s atmosphere and the oceans is increasing because of the high concentration of carbon dioxide (CO2). The rise in CO2 in the earth atmosphere has been observed since the industrial revolution began and it is projected to continue rising. According to America's Climate Choices "The average temperature of the Earth’s surface increased by about 1.4 °F (0.8 °C) over the past 100 years, with about 1.0 °F (0.6 °C) of this warming occurring over just the past three decades" (2011). With that data we can figure out that the temperatures are increasing very…show more content…
For example, the United States Environmental Protection Agency (EPA) reported, in 2011, the quantity of greenhouse gas emission in the United States was 6,702 million metric tons of CO2 equivalent. This gas emission is associated with human activities. For instance: 33% comes from electricity production, 28% from transportation, 20% from industries, 11% from commercial and residential activities, and 8% from agriculture. However, only 14% of those emissions are offset by natural processes (EPA, 2013). It is clear that land use and forestry only assimilate a smaller amount of gas emissions compared with the quantity of them generated for anthropogenic activities. In contrast to this data, some skeptics have used the results of the scientific studies to show that greenhouse gas emissions is a regular process through the Earth’s history. One of those studies is the measurement of CO2 from ice cores. The Survey British Antarctic collected and reported the results from the ice cores collected in Antarctica and Greenland. The ice cores register the ages of the water from 800000 years ago until 2008, which is year that is considered as “zero”. The ice has air bubbles that contain the gasses of the atmosphere when the water was frozen; as a result, scientists get the information from them and calculate the temperature patrons about the past. The following
