The Causes Of Global Warming

The greenhouse effect is widely known, but regularly misunderstood. The greenhouse effect is the absorption of sunlight, radiated back to the atmosphere as a longer wavelength reflecting back on Earth as heat energy. The concentration of heat energy makes the Earth warmer raising our daily problems. The effect takes place in six steps. Solar radiation first reaches the Earth’s atmosphere where some is reflected back into space. The sun’s energy is absorbed by land and oceans, heating the Earth overall. Heat radiates from earth towards space. Several of the heat is trapped by greenhouse gases in the atmosphere, keeping the Earth warm enough to sustain life. Human contribution to global warming increases the amount of

Global warming is the increase in temperature of earth’s atmosphere. Earth's climate has changed throughout history. Many different types of information have been collected about our planet and the climate, it’s also shown the signals of a changing climate. Global temperature rise, warming oceans, shrinking ice sheets, decreased snow cover, rising sea level, and much more has been shown as evidence for rapid climate change (NASA)

Global warming, the rise of average global temperatures year, after year. A serious issue yet many people fail to pay much attention to it, or even realize how much of a problem it is. Some people think it’s a hoax from lack of proof, but some scientist would argue otherwise. Human activity such as burning fossil fuels is the main contributor to global warming, as it releases large amounts of C02 into the atmosphere (May). With deforestation happening every day less, and less trees are available to absorb the C02 released into the air. The average temperatures within the US have been rising. This creates droughts, evaporation of lakes, major storms, and devastating floods (May). To combat global warming it is important to support the development of clean renewable energy, such as solar power. Not only is solar a free source of energy, it is clean in that it doesn’t emit C02, and it creates thousands of well-paying jobs. Global warming is caused by human activity, and has large devastating effects on our environment, to sustain a growing human population we must seek alternative energy such as solar power.

Global Warming is overall increase in temperature of planet earth due to emissions of green house gasses like carbon dioxide, and nitrogen. Human activities like fuel burning in industries and automobiles, burning down the forests and human waste release sufficient amount of greenhouse gasses in atmospheric layer of earth. Atmosphere consists of carbon

Global warming has been a hot button lately in the news. The main reason why global warming has been big issue is because people argue if global warming is real or not. There are good points to both sides of the argument. Even though temperatures have not been recorded since around 1850, some scientist believe there is not enough data to confirm global warming , global warming does exist because rise in average temperatures and the glaciers in antarctica and other mountain ranges are shrinking.

Why are the temperatures are steadily getting hotter? Summers getting longer and winters shorter? Glaciers melting and sea levels rising? The reason is Global Warming. What is Global Warming? Global warming is when the world, the globe’s temperature increases and it starts to get hotter. The reason it starts to increase is because of what is called the greenhouse gases. The green house gases are mainly caused by humans which also means that , the humans are causing global warming. Humans have been releasing gases into the air as they go on with their modern lives. The main gas that goes into the atmosphere is carbon dioxide and that comes from everyone, 28% comes from transportation ,10% from agriculture, 20% from industry, 10% commercial and residential, 32% electricity that's 82% of carbon dioxide that's in the atmosphere. The other 18% comes from Methane 9%, nitrous oxide 6%, Fluorinated gases 3%. The first time they discovered and saw the increase in greenhouse emissions was back in 1800’s when the first industrial revolution was happening the scientist discovered this by studying the ancient ice, they also discovered that the level of the carbon dioxide was 290 parts per million (ppm). By 1960 Charles Keeling measured the level of carbon dioxide and it measured 315 ppm. By 1970 April 22 the world marked the first Earth Day on their calendars to raise awareness and help their environment. It wasn't until 1976 that the scientist discovered that carbon

Global warming is an on going issue that exists and affects the entire globe. It is defined as the increase in the overall temperature of the Earth’s atmosphere. The science behind global warming explains its occurrence as incoming sun radiation in the form short waves is transmitted to the atmosphere. Then the Earth’s surface absorbs the radiation. Once the radiation is absorbed it is converted into long wave radiation, which takes about two to three hours; after its conversion the surface emits long wave radiation back to space. However, some of the long wave radiation gets reradiated back since it is not able to pass through the atmosphere due to the weakness of the long waves. Green house gases such as water vapor, carbon dioxide, ozone, and more then absorb the reradiated radiation causing the Earth to warm, which is known as the green house effect. The intense warmth of the Earth’s surface has lead to global warming. Despite, global warming being a global issue it is also a controversial issue. Since scientists are unable to come to an agreement upon the “real” cause of global warming. The scientific realm is a divided spectrum, where one side such as the International Panel on Climate Change argues, that cause of global warming is due to anthropogenic activities, which have caused the significant increase in the concentration of green house gases. On the other end of the spectrum the Non-governmental International

Have you ever wondered the causes of global warming? One of the major causes of global warming is the greenhouse effect. The greenhouse effect is caused by the atmospheric accumulation of gases. One of the gases is carbon dioxide. It is mainly, carbon dioxide, methane, and nitrous oxide. They absorb the infrared radiation produced by the earth’s surface. The greenhouse effect produces solar radiation. Solar radiation is energy radiated from the sun in the form of electromagnetic waves, including visible and ultraviolet light and infrared radiation. For every 100 units, roughly 30 units are sent back to space by the clouds, the atmosphere, or reflective regions of earth’s surface. The other 70 units, possibly could be absorbed by the atmosphere, clouds, or the earth’s surface, but in order to maintain thermodynamic equilibrium, Earth’s surface and atmosphere must radiate the same 70 units back to space, but also produce more than those original 70 units back to space. From the greenhouse gases absorbing some of the infrared radiation, the same 70 units does not escape

Climate change is definitely not an uncommon idea in today’s society, in fact, it seems to be at the center of many discussions: who believes in global warming, who does not, and why is climate change happening? Some people strongly believe that humans are the cause of climate change with all of the methane, carbon dioxide, and other greenhouse gasses that are released because of the way humans carry out their day to day lives, but others believe it is occurring naturally from different cycles on the Earth. However, it is anthropogenic action that is the catalyst for these positive feedback loops occurring from the Earth’s cycles that are continually causing more carbon dioxide to be released into the atmosphere.

Temperatures are rising and we need to help. Global Warming is a problem that is affecting our globe dramatically and is often thought of as a joke to skeptical people. Global warming was first discovered about 60 years ago and has become a very heated topic in modern society for environmentalist. Global warming has many causing factors, but a main one is the production of gases such as carbon dioxide from cars and factories. Global warming is melting ice caps, causing temperatures to rise, and causing droughts and floods.

Global warming is a gradual process of heating of earth’s surface and whole environment including oceans, ice caps, etc. The global rise in atmospheric temperature has been clearly noticed in the recent years. According to the Environmental Protection Agency, in the past century there is increase in the earth’s surface average temperature by around 1.4-degree Fahrenheit. It has also been estimated that global temperature may increase by another 2 to 11.5 degrees F in the next century.

There are two sides on what has caused global warming; chemistry, and the physical aspects. In specifics, the greenhouses are collected in the atmosphere, absorbing sunlight and solar radiation that have bounced off of the earth’s surface, and can’t escape, so the air pollutants keep absorbing, and gaining heat, instead of escaping into outer space^4. Carbon dioxide, which is a byproduct of combustion of fossil fuels, which is where humans burn coal and oil to heat homes, and use in vehicles. In the reaction of burning fossil fuels, O2 reacts with glucose and the end product is water, carbon dioxide and energy, shown in the chemical reaction below^2:

Global warming is a gradual increase of the overall temperature of the earth’s atmosphere, caused by the greenhouse effect. In natural circumstances the heat that is radiated by the sun should be re-radiated by the earth’s surface, whereby most of the heat escapes into space. However, increased carbon dioxide emissions and other air pollutants by humans cause more heat to be trapped in the

‘’The weight of scientific evidence suggests that the observed changes in the earth’s climate are, at least in, due to human activities’’ (Kerr). Is primarily caused by human activities that started during the Industrial Revolution, when human burning of fossil fuels began to increase drastically, releasing large amount of carbon dioxide, methane, nitrous oxide, and artificial chemicals called halocarbons have long been increasing as a result of emission from fossil fuel burning and other activities. Increased atmospheric concentrations of these gases are causing earth to warm.

Global warming is the rise in the earth’s average atmospheric temperature. When sunlight heats the ground surface, it releases most of the solar energy it has absorbed as infrared radiation. Then what is known as the “greenhouse effect” occurs, this is where the gases in the atmosphere absorb the re-radiated infrared radiation and the escape of these gases being released into space is prevented. As long as the composition of greenhouse gases in the atmosphere does not change, the heat in the atmosphere will remain constant by releasing the contained heat into space. It has been noted that greenhouse gases, such as carbon dioxide, water vapor, and methane, have been increasing steadily since the early 90’s, and around this time the average
