With the rise in modern technology, the average temperature of the Earth’s surface has increased about 1.4 °F; two-thirds of which has arisen since the early 1980’s. Industrialized countries are major contributors to climate change, due in part to their involvement in deforestation and the burning of fossil fuels. These activities lead to an increase in levels of greenhouse gases, which scientists propose is the number one cause of global warming. The greenhouse effect is an example of external forcing: any process that has influence over climate, outside of the climate system. When infrared radiation is emitted and absorbed into the atmosphere, the greenhouse effect occurs.
Global warming is a war that we should not get involved with because we will lose if changes aren’t made soon. Global warming is the rapid increase in earth’s average surface temperature over the past century due to the fact that greenhouse gases are being released into the atmosphere increasing the earth’s average temperature (EarthObservatory.NASA.org). There are many contributing factors that play a role into the cause of global warming. Greenhouse gasses are gasses such as Carbon Dioxide, Methane, Nitrous Oxide, and F-gasses that trap heat in the atmosphere. The heat that is trapped in the earth’s atmosphere is a slowly melting glaciers, cause sea levels to rise and is messing with the weather patterns.
The gases are emitted mainly by cars, power plants, and other industrial sources that burn gasoline, coal, and other fossil fuels. Obviously, the emissions of these greenhouse gases in excess are leading to the planet’s consistent increase in temperature. For example, in a study conducted by the National Center for Atmospheric Research, it was confirmed that earth’s early century warming was caused by mostly solar and volcanic forcing, and the late century warming, from 1940-2000, was mostly caused by the increase of greenhouse gases. The National Resource Defense Council states, if global warming persists, there will be more air pollution and problems with water supplies as precipitation patterns change, as well as huge threats to ecosystems from the Everglades to the glaciers. Not only will there be hotter, longer heat waves and more intense storm systems, but also forests, farms and cities will face troublesome new pests and more mosquito-borne diseases.
Climate Change and Business as Usual Scientists have shown that over the past 150 years, since the start of the Industrial Revolution, human activities have been a substantial contributing factor to climate change. Emissions from carbon dioxide (CO2) and other heat-trapping gases, also referred to as greenhouse gases, have increased the greenhouse effect that causes the atmosphere to retain heat. This in turn has caused the earth’s surface temperature to rise. This is known as climate change, and the primary human activity causing it is the burning of fossil fuels. Although CO2 is absorbed and emitted naturally through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange, atmospheric CO2 emissions have increased nearly 40% from pre-industrial times.
The effects of global warming have caused humans to open their eyes to the ecosystems’ vulnerability as well the inhabitants housed there. The cause of global warming can be attributed to greenhouse gases (Robinson et al 2009). Greenhouse gases present in the atmosphere allow the Earth to remain warm by providing a blanket like cover. However since the nineteenth century humans have caused an increase in the production of greenhouse gases in the atmosphere due to the growing oil and coal economy (Robinson et al 2009). The increase in greenhouse gases as a result of burning fossil fuels is like throwing a second blanket on top of the Earth.
Humans impacts on global climate change continues to accumulate. Data indicated that earth’s surface temperature is rising. This increase can be attributed, in part, to human-caused increasing in greenhouse gases such as carbon dioxide. It is becoming apparent that these climate changes are negatively affecting physical and biological systems worldwide. Carbon dioxide and other pollutants result from burning of coal to produce electricity.
The 20th century’s ten warmest years all occurred in the last fifteen years. Also the 20th century was the warmest globally in the last 600 years (Global Warming and Carbon Dioxide, 3). Effects of this increase are the melting of glaciers, rising sea levels, more frequent heat waves and droughts, and heavy rainfall. The burning of fossil fuels such as coal and oil are a main source to why the greenhouse effect is being enhanced and likely contributing to global warming (Global Warming and Carbon Dioxide, 4). To hinder this increase in the global warming process we must reduce CO2 emission, we have to use different sources of energy, and we must recycle.
The Threat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we are now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath.
And the reason behind this is the use of fossil fuels. C02 which is also an important constituent of environment is causing a warming effect on the earth’s surface. But where is so much of CO2 coming from? Fossil fuels like coal, oil, and natural gas are being burned to provide energy. Ken Caldeira (2012) in his article “The Great Climate Experiment” talks about how Co2 is being released in the atmosphere (p. 80).
How does Greenhouse effect impact climate change? Kenneth Hare reviews the scientific evidence on the greenhouse effect and explained that warming on global and increased greenhouse gases is the main issue that impact climate change. Human activity is the one who causes the greenhouse effect. The natural greenhouse effect is benefit to our world and become probable to making life on earth, but the temperature is very high nowadays that harm human, plant, and animal life. For example, the natural resource such as petrol for vehicles and electricity for our necessary needs will produce more than billions of carbon to the atmosphere every year that cause climate change every day in our earth.
