Global warming is an international disaster. Its effects and control have dominated virtually all facets of modern human life. It is not uncommon to find even groceries listing themselves as being “eco-friendly” in a bid to attract the environmentally conscious customer. The effects of global warming are not just about blowing hot air in the pursuit of delivering chilling information. This phenomenon has devastating consequences for all, regardless of geographical location. One of the most commonly known effects is the heating up of the atmosphere. Scientists have shown that there is a direct correlation between the increase in carbon dioxide levels and an increase in the temperature of the earth. As a result, warmest years since 1992 have been experienced in recent years according to the IPCC report (2007). Global warming has various devastating effects on life sources such as plants, animals, food sources and climate change. Greenhouse gases are considered air pollutants by the law. The Supreme Court decided that greenhouse gases meet the definition of air pollutants in the Court’s decision in Massachusetts v. EPA (2007). Greenhouse gases were considered air pollutants because they endanger public health and welfare. After the ruling, EPA adopted greenhouse gas emission standards for new cars and light-duty vehicles in April 2010, and the agency has a legal obligation to regulate greenhouse gases under the Clean Air Act (EPA 12).

In the last 100 years, the amount of greenhouse gases in the atmosphere has increased, causing the Earth to warm by an average of 0.6 degrees celsius, largely a result of burning fossil fuels for energy, transportation, and land use changes increased for food production. The basic science is straightforward and climate researchers have shown that gases such as carbon dioxide, methane and others can trap heat in the Earth’s atmosphere, causing a phenomenon known as the greenhouse effect. Human activities such as industry, transport, energy generation and deforestation all produce these greenhouse gases. In the last 20 years, concern has grown that global warming is inevitable and now considered most probably caused by man-made increases in
Global warming is one of the most tumultuous topics in today’s society. Some believe it is happening as we speak, while others question its very existence, So, is it real, or is merely a hoax? There is no one answer, but evidence does overwhelmingly support the former. Surely we have all heard this word at one time or another, but few individuals actually know its true definition. Justifiably, however, global warming is not that simply explained. In layman’s terms, it is the dramatic increase in the Earth’s average air and ocean temperature since the 20th century. This increase is primarily attributed to two main culprits: the greenhouse effect and human activity, such as fossil fuel burning. In both cases, carbon dioxide (CO2) is the
The society of the modern day and age is characterized by a wide array of elements, such as unprecedented levels of technologic development, ongoing fights for human rights and societal development, but also high levels of environmental threat. The global warming phenomenon has, for decades, been assessed with importance and reticence alike. While some would argue the severity of the raising global temperatures, others would attest that global warming was a make belief phenomenon. Today however, as science has proven the existence of the phenomenon, more measures have to be taken to ensure environmental stability.
Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.
Global warming is the steady heating of Earth’s land, oceans, and atmosphere caused primarily by human activity. Climate change is one of the world’s biggest challenges right now, from people actively arguing that it doesn’t exist- to other’s who don’t care enough to do anything about it. There’s evidence showing that climate change is happening and affecting our world now and from what it seems, if action isn’t taken, major consequences will soon arise. Most of the world’s land mass has experienced a 0.2-1.0 degree Celsius average temperature increase since the 1970s, the temperatures of the Artic has increased at almost twice the mean global rate. Climate change is caused by human factors such as greenhouse gases and ozone depletion and because humans are so dependent on fossil fuels in their day to day lives, the issue at hand is only going to get worse.
All over the world mankind commonly references mother Earth as important and fragile and even locally there are second graders at Cornerstone elementary singing Native American songs describing how “the Earth is our mother, we must take care of her.” The rising issue of global warming, scientifically known as climate change, is slowly becoming a worldwide epidemic that only 53% of Americans are even worried about, according to a 2014 survey by the IPCC. The definition of climate change is a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. The first studies of climate change and human carbon dioxide emissions started in 1896 by a man named Arrhenius. The interest was renewed during the cold war era when several satellites were launched and more data taking resources were available. 1970 was host to the first Earth day and since then global warming has gained more and more awareness and understanding. The cause of the average global temperature is due to the greenhouse effect, in which the suns heat and energy heats the Earth’s surface then gets absorbed by greenhouse gasses and re-emitted in all directions warming the surface and the atmosphere. With more than 1300 scientists on the IPCC team
Global warming is and has been known as one of the largest and most challenging problems that pertains to the environment today. Around the world many are experiencing negative impacts on the daily, those from farmers to those living in more forest like environments. As the ecosystem becomes more and more devastated, awareness and prevention of climate change has never been more important. Many people doubt the existence of global warming, however its is clearly evident through the intensification of heat waves and the melting of ice caps.
Nowadays, global warming has increased dangerously in a way that affects every creature’s existence and health. On the one hand, there are the natural causes. Over the years there have been massive explosions from volcanoes which have affect the atmosphere and the temperature. Another problem is that the sea levels are rising worldwide because the ice is melting. To be exact, many cities are in danger of sinking because of that.
Antarctic’s ice melt and accelerating sea level rise, the growing number of large wildfires, intense heat wave shocks, severe drought and blizzards, disrupted and decreased food supply, and extreme storm events are increasing to happen in many areas world wide and these are just some of the consequences of global warming. The fossil fuel we burn for energy coal, natural gas, and oil plus the loss of forests due to disforestation, in the southern hemisphere are all contributors for climate change. In the past three decades, every single year was warmer then the previous year and the warmest 12 years were recorded since 1998. We are overloading our atmosphere with carbon dioxide and trapping the heat and
Consequently, the greenhouse gasses that most affect the atmosphere include: carbon dioxide, water vapor, methane, tropospheric ozone, and nitrous oxide (“Greenhouse Gases: Introduction”). The overall effect of the presence of certain gases depends on its abundance, concentration and the amount of time spent in the atmosphere. Water vapor is the most predominant gas in the atmosphere but it spends only about nine days there whereas carbon ioxide, another powerful gas, spends about five years (Schlesinger). The United States Environmental Protection Agency found that “In 2011, CO2 accounted for about 84% of all U.S. greenhouse gas emissions from human activities” (“Carbon Dioxide Emissions”). Carbon dioxide is an organic gas which is naturally found in the earth’s Atmosphere but the level has drastically increased since the start of the industrial revolution. This is because carbon dioxide is released during the combustion fossil fuels (ie. oil, natural gas, and coal) which occurs when generating electricity, transporting people and goods, and producing products. Electricity accounts for thirty eight percent of emissions, transportation thirty one percent, Industry fourteen percent, and the last sixteen percent a combination of residential and commercial and other sources (Carbon Dioxide Emissions). Talks in 1997 brought about the Kyoto Protocol on February 16, 2005. The Kyoto Protocol included thirty six countries making individual goals for
Unfortunately, with the amount of carbon dioxide increasing so dramatically, the greenhouse effect has been strengthened and global temperatures have started to increase above norms. Based on weather data collected around the world, climatologists have detected increases in global average temperatures over the last few decades (Bloom). This increase has also triggered many other environmental changes such as the shrinking of glaciers and ice sheets, shifting of plant and animal ranges, accelerated rise of sea levels, changes in precipitation, longer and more intense heat waves, and more detrimental and intense severe weather events (NASA effects). What is most worrisome for all inhabitants of Earth is not the change itself, but the rate at which it is occurring.
This paper will define global warming and discuss how greenhouse gases affect the Earth. While greenhouse gases are necessary for life to exist on Earth, an overabundance or shortage of greenhouse gases can be detrimental. Human activities have caused an overabundance of these gases, and it is necessary for humans to become aware of how their activities affect the Earth. It is necessary for humans to begin modifying their behaviors that cause global warming and its negative effects, such as severe weather pattern changes, rises in temperatures, effects on agriculture, as well as animal and plant extinctions.
For the past 2.5 million years, the earth's climate has oscillated from ice age to warmer periods. In the last almost century the planet's temperature has ascended shockingly fast. Scientist believe it is humans causing this rise in temperature through a term called global warming. Global warming is a term connected to the notion that there is a progressing increase in total temperature of the earth's atmosphere because of the rising levels of carbon dioxide and many other pollutants. This problem has become increasingly noticeable in recent years. Global warming is at an all time high and as time goes on, this problem can only get worse. The issue not only affects our temperatures, but it is impacting our ecosystems and also resulting in sea levels to rise.This report aims to show the explanation of global warming and address the major causes and effects of this natural occurrence.
Throughout the course of history, some people have searched for answers to, “Why is the earth’s temperature increasing?” Daily activities such as the supply of food and the creation of institutions have caused major issues to arise that have put people and animals at risk. Global warming, being the most critical issue due to the changes in our environment, wildlife, and human life, has to be altered to help save the human and animal race on our planet.
Global warming, also known as climate change, is the ascent in the average temperature of the earth’s climate. It is caused by the “greenhouse effect”, which is the accumulation of carbon-dioxide(C02) and other pollutants and greenhouse gases in the atmosphere which absorb solar radiation which is normally reflected back into space. Although it is caused by various factors, the largest sources of this heat-trapping pollution worldwide are the burning of fossil fuels for electricity and transportation. The global temperature is rising rapidly. “Over the past 50 years, the average global temperature has risen at the fastest rate in recorded history” (MacMillan). The majority of the scientists and scholars agree that this rapid increase in global temperature leads to many environmental, social, economic, and political problems. Global warming has been an affair of controversy in the past few decades. Every national and international scientific body agree with the existence of this phenomenon. However, a limited number of scientists still argue against its existence. Global warming is real because with the passage of time, its effects are becoming more apparent and there is abundant scientific evidence that corroborate its existence.
