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.
We live at a period in time were natural disasters have become a current event in our world. The Earth’s climate is changing, the culprit, global warming. This is what popular media has guided us to believe. What causes global warming, “we do, with the emissions of carbon dioxide we produced”, claimed by the noble prize winning movie, The 11th Hour. Although in reality the Earth’s climate has gone through spikes in climate changes for centuries.
This essay will discuss the problem of global warming, the causes and suggest the best ways to solve this controversial issue. The factors responsible for global warming are both natural, and man-made. Many of the causes of global warming are human activities, which contribute to green house gas emissions in the atmosphere. The increase in greenhouse emissions in the atmosphere reinforces the green house effect, which later leads to global warming. The largest contributor to global warming is carbon dioxide, as it holds the largest part of green house gases in the atmosphere.
There are many ways that natural global warming can take place. Greenhouse gases are ones that trap the heat of the earth and reflect it back (“Global Warming Definitions”). Carbon dioxide (CO2) is an example of these. Greenhouse gases are given this name because they act like a giant greenhouse around the earth (“Climate”). These gases can be put into the air as a by-product of what humans use to run their lives.
There are people in the world that believe that there is another reason why this is happening; earth is experiencing a natural cycle of evolution. Global warming is a very serious part of the world and a solution needs to be found immediately. The greenhouse effect is the cause of global warming in the world. The greenhouse effect is a topic of discussion throughout the world; it needs to be contained immediately. “Our effect on the environment, and in particular on climate change, is large and growing” (Tony Blair) The greenhouse effect is when sunlight and solar radiation enters the atmosphere and hits the earth and bounces back, but with the greenhouse effect it then goes back up into the atmosphere and is deflected back down and trapped in the atmosphere (Energy and the Environment).
Global warming comes with a plethora of negative outcomes and we need to stop it. Global warming is a serious issue effecting the entire world. Global warming not only affects our weather when it comes to temperature, but also precipitation including rain and snow. Global warming causes negative effects on animals, some species no longer populate certain areas due to climate change and are migrating in order to survive. Scientists say that the sea levels have increased due to the melting of the glaciers.
Once an uncommon term used only by scientists and climatologists, the notion of Global warming today is commonly heard but very misunderstood. One might ask, what exactly is global warming and should we care? According to "What is Global Warming?" in LiveScience, global warming is a gradual increase in the temperature of Earth's surface and atmosphere, that has become a world-wide environmental issue.1(Lallanilla,2013) Similarly, this topic is one of great controversy because of widely differing opinions on current global warming rates and the impact by humans.This suggested anthropogenic activity creates carbon dioxide, methane, and other gases that are released by the burning of tropical forests and fossil fuels, powering plants, heating homes, and traveling.2(Kessel,2000) On top of rising temperatures, global warming is feared for its effects on climate change, such as rising sea levels and the melting of glaciers, that will ultimately result in a non-sustainable environment and negative health consequences for mankind. Life on earth depends on climate, and changes in it directly effect the health and well-being of the population, biodiversity, and the delivery of services by ecosystems around the world.
