The Causes And Effects Of Global Warming

Global warming has become a world wide issue and an issue that is causing great controversy. It is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (Dictionary). Global warming is a natural process, but because of increase in certain activities this process is taking a faster and more dangerous route creating global problems. Global warming was first theorized in 1894 by Jean Baptiste Joseph Fourier a French mathematician, who noticed the earth was gradually increasing in temperature. He came to the conclusion that the earth’s atmosphere was trapping solar radiation caused by the sun and reflecting this radiation back to

Global warming is caused by an effect called the greenhouse effect. Gases like Nitrous Oxide, Water Vapour, Carbon Dioxide, and Methane are released into the atmosphere by human industries and are forming a blanket around the earth. When sunlight enters the atmosphere it passes through the atmosphere as ultraviolet and visible light. (Ultraviolet meaning of electromagnetic radiation, having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays - a type of electromagnetic rays which are used for medical purposes). It emits shorter wavelengths because the sun has a lot of energy and heat to give off and hotter energy has shorter wavelengths. Some of this energy is then reflected back towards space as infrared energy. (Infrared energy meaning of electromagnetic radiation, having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.) The earth is cooler and has less energy to give off so the suns energy is cooled down and the wavelength increases because cooler energy has longer wavelengths. Now gases such as nitrogen and oxygen that make up our atmosphere are only two particles, and therefor are tightly bound and don’t absorb much heat. But, greenhouse gases, having three or more particles result in being loosely bound structures that are efficient absorbers of

CO2 Emissions have steadily increased since the industrial revolution. The world is now producing too much CO2 and the planet cannot clean up after us humans. This leads to heat from the sun getting trapped into our atmosphere, producing heat and pollution, known as Global Warming. Everyday activities from humans are damaging the environment. Having both Natural Sources and Human Sources of CO2 it becomes a very hard problem to solve and with unimaginable consequences. There are many ways to reduce CO2 emissions in the planet, some which include electric cars, solar, nuclear and hydropower energy. Although some people will claim that nuclear energy will not work or question its safety, it has become a major alternative power supplier in the world to help reduce the CO2 emissions that lead to global warming and potential extinction of life.

Global warming refers to an extended increase in the earth's average and average temperatures of the atmosphere and water bodies especially the oceans and seas. The problem of global warming has resulted in various negative ramifications affecting humankind. Human activities have significantly led to the increasing effects of global warming that is experienced in different places worldwide. Global warming was experienced in the 20th century when the earth's average temperature rose by 0.60 Celsius from an average temperature of oceans and the atmosphere (Ritter, 11-21). Global warming distracts the typical living conditions since the temperatures increase to extreme limits and deplete the Ozone layer which is meant to protect human being from the effects of direct rays of the sun. The Ozone layer is very significant and needs to be preserved to avoid the impact of direct sunshine which causes sunburns on human skin. It is clear that global warming has been increasing to a more significant extent since the 18th century due to the actions of human beings themselves. The core reason behind this tremendous increase is the new developments in technology and setting up of industries. Industries emit dangerous gases from burning fossils fuels, gasoline hence producing carbon dioxide which depletes the Ozone layer which is purposely meant to shield the earth from direct sunshine. This paper discusses the various causes of global warming that has been majorly attributed to humans

Global warming is affecting us as human beings more and more every year. It’s affecting our agriculture, even though plants are very resilient. It also can affect our cities near the oceans if the temperature rises too much. But global warming doesn't just affect us, it affects wildlife and nature too. Deforestation is one of the leading causes of global warming by releasing carbon dioxide into the air, it also has a effect on aquatic life by causing problems with their ecosystems.

Global warming or climate change is a very serious problem in the world today. “Global warming is the current increase in temperature of the Earth's surface (both land and water) as well as its atmosphere,” says Emily Crouse. Global temperatures have risen about 1.4°F over the last hundred years. As small and unimportant as this sounds, it is extremely dangerous for this Earth. If the temperature has risen this much in 100 years what will happen in 1,000? Rising temperatures mean rising sea levels, more wildfires, bigger and stronger storms, more allergies and disease outbreaks, and so much more. There are many causes of global warming, whether it be by human or naturally, for instance, deforestation or the burning of fossil fuels contributes to global warming in a negative way.

Global warming is the observation of the Earth increasing in temperature over the last few centuries and is a topic of interest for both politicians and media alike. The media regularly contain headlines referring to the effects of global warming and is often resurrected in debating the latest powerful storm or unexpected heatwave. This will continue to be of major concern for many years into the future, especially since there are two very distinct camps; one which does not consider global warming to exist and the other which believes that it most certainly does and therefore needs acting upon by both the politicians and scientists.

Global warming over the past 50 years has been experiencing rising global temperatures from the human trend “greenhouse effect”. The role on human activity have produces greenhouse gasses such as carbon dioxide, methane and nitrous oxide causing much of earths temperatures rising over the past 50 years. The impacts of Global warming are fueling frequent droughts, heaver rainfall, hotter heat waves, and powerful hurricanes. Global warming occurs when greenhouse gasses, carbon dioxide, and other hazardous collect in earth’s atmosphere absorbing sunlight and solar radiation trapping heat and causing temperatures to rise. In the United states, the burning of fossil fuels to make electricity is the largest source of pollution, producing carbon dioxide. Fossil fuel burning such as coal and oil power plants are the country’s biggest polluters. The country’s second largest source of carbon pollution is transportation sector. Transportation sectors such as automobiles, planes and trains generates about 1.7 billion tons of carbon dioxide emissions a year. Due to the advancements of scientist, energy efficient technology, modernized power plants now burn less fossil fuels decreasing the emission of carbon dioxide. As a result, the effects of global warming are melting glaciers, effecting agriculture, disruption of habitats, and the spread of conditions favorable to pathogens.

It has been known that Earth’s atmospheric temperature has risen over the decades, the exact term for this is called “Global Warming”. So, what exactly does this mean? To simply state it, heat is emitted into the atmosphere and then eventually released. Some gases such as carbon dioxide, water vapor and methane capture heat more efficiently than others and are called “greenhouse gasses”, and if the atmosphere contains more of these gases, it retains more heat and becomes warmer, thus causing the rise in atmospheric temperature. “Global levels of greenhouse gases have been steadily increasing. In 1990 they were more than 14 percent higher than in 1960. According to the National Oceanic and Atmospheric Administration (NOAA), which measures long-lived greenhouse gases and publishes an Annual Greenhouse Gas Index (AGGI), greenhouse gases increased 37 percent from 1990 to 2015, and of that, carbon dioxide accounted for 80 percent of the increase (Keating).” This results in significant changes in climate and weather patterns. The rise in average temperatures is crucial and is already causing changes in the climate, “Documented changes include the net loss of ice due to melting glaciers and slowly rising sea levels as the ocean gets warmer and its waters expand (Keating).” So where exactly do these gases in the atmosphere come from, Scientists have discovered that “One significant factor, the rise in greenhouse gases, has been attributed to the activities of humankind.

Now is summer. Every year during July to September, these are the hottest days for people who live in the Northern Hemisphere. In NYC, The mercury reached 104 degrees in Central Park at 2:10 p.m. on Friday, 2011. The hottest New York City has been since July 21, 1977, and only two degrees shy of the hottest temperature ever officially recorded in the city. Over the past 50 years in the world, the average global temperature has increased at the fastest rate in recorded history. Global Warming not only refer to as climate change in the world, it also has caused a lot of other problems. The current warming trend is particular significance, because scientists have concluded that mostly human activity since the mid-20th century is the major factor in causing Global Warming. Some people don’t believe that Global Warming really happens, but it is happening around the world believe it or not.

For the past few decades, there has been controversy whether global warming actually exists. Is it real or is it a hoax? According to NASA, “Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves” ("Global Climate"). The cause of these effects is the greenhouse effect. According to National Geographic, “The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat” (“What Is”). An example of changing the natural greenhouse is burning fossil fuels, which can result in global warming. So what are the consequences, and are they really that bad? Global warming can lead to more droughts and heat waves, stronger hurricanes, and rising sea levels.

Global warming is one the largest and most current dilemmas the earth is facing. “Scientist are reporting the second mass bleaching in the Great Barrier Reef in the last year. In a Yale environment 360 interview, researcher Terry Hughes says these events have damaged two-thirds of the world’s largest coral reef and are directly caused by global warming”-Richard Schiffman. Have you stopped to question yourself, why has our climate become so unpredictable over the years? There is no dispute that global warming is causing the destruction of our environment and is the main cause natural disasters are occurring.

Scientists around the world have been researching climate change since the 1970’s. One thing most agree on is that the temperature of Earth is rising at a rapid pace and that global warming has been caused mostly by human activity. Our atmosphere contains gases that act as a blanket, because it traps heat from the sun and prevents it from escaping back into space. The trapping of the sun’s heat by these gases is known as the greenhouse effect, and the gases are called greenhouse gases. The main greenhouse gases that occur in nature are carbon dioxide, methane, and nitrous oxide. Without the greenhouse effect, earth would be too cold to support life.

The world today is facing a large number of problems from war to high unemployment rates but the biggest danger the earth is facing is global warming and it has the power to destroy many regions around the globe. “Global warming is the gradual heating of Earth 's surface, oceans and atmosphere. Scientists have documented the rise in average temperatures worldwide since the late 1800s. Earth 's average temperature has risen by 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past century, according to the Environmental Protection Agency (EPA). Temperatures are projected to rise another 2 to 11.5 degrees F (1.133 to 6.42 degrees C) over the next 100 years.” (Bradford, By. "What Is Global Warming?" LiveScience. TechMedia Network, 15 Dec.

Intro- Imagine a life where polar bears in the Artic are extinct. Cities along the coast no longer exist from the ocean rising and covering it. Heat waves and floods are much more common. All of these things are predicted to happen in the future due to global warming. Whether humans cause global warming or if it is natural has been at debate for a long time.
