Essay on The Threat of Global Warming

Since the mining of Natural gases and energy, Emissions of greenhouse gasses have been slowly releasing into the atmosphere. This happens by burning the natural gases to create energy for our vehicles or even lawnmowers. On Earth we utilize a lot of energy to maintain a lifestyle we know and love today. But most forms of energy, cars and Farming produce large amounts of green-house gases that can heat and change the earth's atmosphere permanently and cause the ice caps to slowly melt because of constant heating.

A big question is climate change a hazard to future generations? Climate change is and always will be a hazard to future generations and not just for human beings, but for all kinds of species. The comprehension to accept it, is a hazard that species that cannot adapt to the change in climate are more likely become extinct. Luckily, human beings are masters of adaptability. Because our own evolution is a reason for climate change and our capability to adapt. After all, the hazards are always there should we ever fail to adapt fast enough. Our climate is always changing, both naturally and due to human effect on the environment. There were already beyond doubt, proof that animals, birds, and plants are being affected by climate change.

Each year, over 7.2 billion tonnes of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 110 million airplanes all being in the air at once! These disturbing numbers are the foremost cause of global warming, and have been steadily growing over the past few decades. Global warming is caused by this recent surge of greenhouse gasses which consists primarily of carbon dioxide.

Carbon dioxide caused by the burning of fossil fuels is responsible for global warming. The carbon dioxide gas cause global warming by preventing heat from being reflected back to the atmosphere and this leads to excessive heat retention hence global warming. The carbon dioxide is emitted through a process called greenhouse gas mitigation:

The 19th as well as the 20th century have been the most prolific time periods in modern history as concerns science, technology and socio-economic development. Within these two centuries we witnessed the discovery of electricity, the invention of the engine which played a very important role in the maturity of the well-known industrial revolution. Through this revolution people began to live in a more decent and comfortable manner; new commodities were produced and entire new kinds of industry were developed. Although all these inventions, discoveries and scientific breakthroughs improved in an outstanding way our well-being, they also provided us with some troubles that scientists had never foreseen or even imagined.

Greenhouse emissions are made up of all types of gasses such as methane, nitrous oxide, and the leading emission: Carbon dioxide (N/A). “The standard ways of living has increased, as energy supply is the leading cause of greenhouse gas emissions. Transportation also deals with a large amount of greenhouse emissions being released into our solar system. Starting in 1950, greenhouse gasses started to increase dramatically. This

Certain gases released into the atmosphere block heat from escaping. Gases that remain semi-permanently in the atmosphere and do not undergo physical or chemical changes in response to temperature are described as “forcing” climate change while those gases that respond physically or chemically to changes in temperature are termed “feedbacks” (National Aeronautics and Space Administration (NASA), 2016). Known gases that contribute to the greenhouse effect (global warming) include water vapor, nitrous oxide, methane, carbon dioxide and chlorofluorocarbons (CFCs). As water vapor (the most abundant greenhouse gas) increases, the Earth’s atmosphere warms and the possibility of clouds and precipitation increases too. Nitrous oxide is produced by soil cultivation practices especially through the use of commercial and organic fertilizers, fossil fuel burning, nitric acid production and biomass burning. It is a powerful greenhouse gas. Methane is produced through natural sources and human activities. Some of which include the decomposition of wastes in landfills, agriculture and ruminant digestion and manure management. Carbon dioxide is released through natural processes such as respiration, and volcanic activities and through human activities such as deforestation, fossil fuel burning, and land use changes. Studies have shown that humans have

Gases such as water vapor, carbon dioxide, and methane all “have the ability to absorb thermal energy (heat) emitted by the earth and thus are able to warm the atmosphere” (“Greenhouse Gases”). This warming is known as the “greenhouse effect.” The majority of greenhouse gases are a result of humans burning fossil fuels to create energy. With more greenhouse gases in the atmosphere, the Earth’s climate is becoming warmer, leading to threatening consequences for the planet’s population.

When fossil fuels such as coal and oil are burned to produce power for cities, factories, cars and to heat homes, large amounts of polluting gases are produced.

Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,

Many of the greenhouse gases in the troposphere are naturally produced, which is why the Earth is able to stay at a constant average global temperature. Carbon dioxide is the main greenhouse gas in which is affecting global warming, not because of naturally produced carbon dioxide, but mainly because of man made carbon dioxide emissions. Man made carbon dioxide is produced by decomposed fossils, which eventually turn into oil and coal from underground, and are dug up by heavy machinery. Once dug up, the coal and oil are used to power things like fireplaces in homes or machinery like cars, and the expenditure of the coal and oil (fossil fuels) burns and releases carbon dioxide into the atmosphere. This man made carbon dioxide emissions began in the late 18th century and is known as the industrial revolution. Due to this fossil fuel burning, the atmosphere thickens because there is an increase in greenhouse gases that accumulate mainly in the troposphere and a little over half of man made carbon dioxide stays in atmosphere, which can last for a century and means there are more greenhouse gases to trap heat. This causes the cycle of input and output of heat to become unbalanced, and therefore causes a lot more heat to be trapped by greenhouse gases in the atmosphere than is being radiated

Carbon dioxide, or CO2, is the most well known of the greenhouse gases and is produced in the greatest quantities by humans. In the United States alone, coal power plants produce 2.5 billion tons of CO2 per year, and U.S. automobiles produce an additional 1.5 billion tons (NRDC). The links between global warming and human emissions are present in the piles of data we have, and these links are becoming more evident each day, even happening right before our eyes.

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.

Imagine you are placed into the future. The year is 2100. You begin to live in this

“When taking the heating of the entire climate system into account, our planet has warmed at a rate equivalent to 4 Hiroshima atomic bomb detonations per second over the past 15 years” (Cook). Our planet is becoming warmer. When scientists add up all the heat warming the land, oceans, atmosphere, ice melting, earth is accumulating heat equivalent to four Hiroshima bombs worth of heat per second. Global warming is a serious issue faced by our world as there has been a significant increase in temperature over the years. But the article published by Dr. Mark Sircus on “Global Warming -largest science scandal in the history” refutes the theory of global warming. Dr. Sircus states that there is no linkage between carbon dioxide and temperature leading to global warming, the sea level is not rising, arctic sea ice extent is now higher and climate change is due to solar activity. Dr. Sircus also points out that that the recent weather changes are not in line with global warming and “we are in the beginning of a deep freeze” (Global Warming - Largest Science Scandal in US History). NASA and the scientific community states that global warming is not a hoax and there is a rapid increase in Earth’s average surface temperature due to greenhouse gases released as people burn fossils. NASA states that the “key indicators of global warming are based on surface, satellite, and ocean temperature measurements, satellite measurements of energy imbalance and of receding glaciers, sea ice, and
