Atmospheric carbon dioxide is an integral part of the carbon cycle; however, it is also a potent greenhouse gas, absorbing and radiating heat and as a result warms the planet we live on. If the percentage of carbon in the atmosphere is at its natural level these impacts are not a problem, however in our present-day modern world the percentage of carbon is at a much higher percentage and does not show any signs of decreasing; therefore, the negative impacts...

I believe that climate change is a real issue today. There are numerous pieces of evidence and facts to support this statement. Since 1880, the annual temperature has been steadily rising. There are at least five different science agencies that concur with this statement including the Japanese Meteorological Agency and the NASA Goddard Institute for Space Studies. The ten warmest recorded years, according to NASA, have all happened since 2005. According to another study done by NASA, 2016 was the...

The modern world faced the problem of global warming which is considered to be the growth of Earth’s average temperature within oceans and air. It is necessary to underline the fact that this climate change has started to develop since the 20th century and is still in a progressive state of continuation. The true causes of the greenhouse effect are still open to discussion; it should be stressed that there are some debates among the scientists arguing whether human activities...

We see every day the use of person vehicles and how much we depend on them as a society. People in this society travel to work or school by car as it is seen as the most efficient way. We can complain about the issue of traffic, but the individual would still sit in traffic, waste fuel, and increase greenhouse emissions every day as needed. This issue is seen every day and as a society we accept it regardless of...

“The greenhouse effect is the most significant economic, political, environment and human facing the 21st century” (By Timothy Wirth, former US Senator and Undersecretary of State for Global Affairs). It is true that nowadays, due to climate change, our planet is warming at an unprecedented level. Following this, the ecosystem and human life is also affected. That is reason why we had to find the solution to address this problem. According to the studies of scientists throughout the world, the...

Since the industrial revolution took place, it has been observed that there has been a steady and gradual increase in temperature at the earth’s lower atmosphere and this global warming is the result of a natural process called the greenhouse effect. Visible, shortwave light from the sun travels through the medium of greenhouse gases composed mostly of water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Infrared radiation from the planet’s surface is reflected away from the earth’s surface towards...

A geochemical cycle describes the pathway in which chemical elements transfer within the lithosphere (The Editors of Encyclopaedia Britannica, 2014). Examples discussed in this essay are the carbon and phosphorus cycles which are both essential for the development of life. The groundwater aspect of the water cycle is also included, as it involves the movement of water within the lithosphere. Carbon has many biological functions such as being used in the production of carbohydrates, fats and proteins (Marianne, 2016, pp....

Robert Orben once said, “There’s so much pollution in the air now that if it weren’t for our lungs there’d be no place to put it all.” Air pollution comes from many places. The smokestack in a factory, car exhaust, gas from paint, and producing plastic are only a few of the many ways air pollution can be caused. There is no doubt that we need air to breathe. Our lives depend on it. Having said that, society takes advantage...

What is the greenhouse effect and what are the main greenhouse gases? A greenhouse effect is the heating phenomenon of the Earth and its environment due to sunlight incident radiation energy captured by greenhouse gases especially water vapors and carbon dioxide. This process occurs naturally, it happens whenever an incident striking shortwaves attains the gaseous layer surrounding the Earth, one portion is reflected back into space normally, and the other part is captured and emitted on the planet by greenhouse...

Methane is a chemical compound (CH4) including one atom of carbon and four atoms of hydrogen.And it was discovered and isolated by Alessandro volta during his studies between 1776 and 1778 when he was studying marsh gas from lake maggiore. It’s a tetrahedral molecule with four C-H bonds and at room temperature (20 °C) and standard pressure (105 Pa) is a colorless and deodorized gass. It is simplest alkane and it’s the main component of natural gas. Abundance of methane...

During a 2014 Climate Summit, the Secretary General of the UN, Ban Ki-Moon stated, “Climate change has happened because of human behavior, therefore it’s only natural it should be us, human beings, to address the issue.” It may not be too late if we take the decisive actions today. Ban Ki-Moon gave this speech 5 years ago and his words are just as true in 2019. It is our responsibility to limit our gas emissions and air pollution while we...

Our earth contains a specific climate system, continuous increase of the common temperature of the Earth’s climate system resulting in warming. This increasing the temperature is especially by human activities, primarily the burning of fossil fuels that pump greenhouse gas (CO2), alkane series and different greenhouse gases into the atmosphere. A greenhouse emission could be a gas that absorbs energy within the kind of radiation and emits at intervals specific thermal infrared vary. Greenhouse gases can cause the atmospheric phenomenon...

The current challenge of climate change is attributable to different factors, including global warming, pollution, and deforestation. The sustainability of the planet might become unfeasible if different stakeholders fail to collaborate and apply evidence-based measures. The adoption of various economic models is a superior strategy that appears promising and capable of guiding policymakers and nations to tackle the predicament of climate change. This paper begins by giving a detailed analysis of global warming as a major challenge the entire world...
