The current level of carbon dioxide is approximately 398.03 parts per million (ppm). According to the data recorded at the Mauna Loa Observatory, in China, the atmospheric carbon dioxide level has been on the rise for the past ten years, with an average annual increase rate of 2.07 ppm. However, regardless of the current increase in the level of carbon dioxide, previous studies indicate that the current rate of global warming is lower in comparison to the historical data recorded for 450,000 years. This could be attributed to lower temperatures recorded during the prehistoric period. For instance, during the Jurassic period, close to 200,000 years ago, the average level of carbon dioxide was 1800 parts per million. This is approximately 4.7 percent times elevated, compared to the current atmospheric carbon dioxide levels. Furthermore, the level of carbon dioxide was higher during the Paleozoic era due to the existence of human habitats. Human activities such as deforestation, industrialization and burning of fossil fuels are the major sources through which carbon dioxide is added...
Since measurements began in 1958 -- and it can be assumed to have been the case since the industrial revolution -- emission of carbon dioxide into the atmosphere has risen steadily as a result of the burning of fossil fuels (Quay, pp 2344). Although there is much argument over the implications of increasing carbon dioxide levels in the atmosphere, there are several points that almost all scientists would agree on: firstly, carbon dioxide acts to absorb radiated heat; if present in our atmosphere will do just that to some extent. Second, the concentration of carbon dioxide in our atmosphere is rising. Third, the temperature of the planet is rising - although the amount of this increase and the causes of this rise are subject to disagreement (Philander, pp 193).
Global Warming, global concern? I think not. I personally believe that the theory of global warming caused by the infamous carbon dioxide is false. Please, let me explain. First of all, there are more potent, harmful, gases being emitted into the atmosphere. Secondly, the temperature change in the 20th and 21st centuries is extremely slight. Lastly, the earth is currently recovering from a period known as the Little Ice Age.
The levels of carbon dioxide in the atmosphere were 15 times higher than they are today and this was due to the volcanic activity, which released enormous amount of carbon dioxide gas into the atmosphere. The flooding of continents and the lack of plants on land also contributed to the heightened levels. These conditions created a greenhouse effect so tempera...
It's no surprise to most people that the idea of global warming is a highly controversial and debated topic. But is there any real evidence that global warming is a growing problem or is global warming just a big scare tactic being used to get people to comply with strict government regulations? Global warming is widely believed to be the main cause of rising average global temperatures. In reality, global warming isn't really all what it has been exaggerated to be. Many of the predicted effects of global warming over time have actually been proven to be false all together.
When people burn fossil fuels to accumulate and produce energy a substance called carbon is produced. Carbon is released into the air in a form known as carbon dioxide. Carbon moves throughout the biosphere on the planet as it is recycled and reused. Carbon exists in the earth’s atmosphere in two common forms which are methane and carbon monoxide. These gases absorb and retain heat in a process known as the greenhouse effect. The Planets natural greenhouse effect makes life possible by regulating our temperature. It turns out that adding too much to the greenhouse effect can have horrible consequences on the environment. Each year, five and a half billion tons of carbon is released by burning fossil fuels and of that three billion tons enters the atmosphere. The remaining carbon usually gets absorbed by the oceans.
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).
Well it hasn't for the last 800,000 years. Ice core data shows that the fastest rate of CO2 increase over the last 800,000 years was 30 ppm in 1000 years.
Ever since the dawn of the Industrial Revolution at the end of the 18th century, fossil fuels have been used constantly, slowly changing the planet’s atmosphere. According to Mann, “the preindustrial level of CO2 was 280 parts per million (ppm)” (N. pag). He predicts that at current rates, we will reach 560 ppm by the end of the 21st century. To make matters worse, Mann states that 450 ppm is dangerous as it will cause an increase in Earth’s average temperature by 2 Celsius. He recommends taking measures to keep CO2 at less than 405 ppm (N. pag). Mann takes note that in 2013, the value managed to reach 400 ppm (N. pag). It is needless to say that the point of no return is right around the corner. Unfortunately, the affects of pollution are already felt around the world. Pollution can cause many health issues and damage several organs in the body. When people think ...
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Imagine a world under 2 feet of water and in total chaos. Then throw in almost biblical floods, Fissures in the earth that can be seen from space, and Tornadoes that could uplift even the biggest buildings. This is what Al Gore wants you to think. These statements are completely and utterly false. These accusations upon the people of the U.S. are not true and must be silenced.
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
There are many different views on whether global warming is actually real or not and possible catastrophic damage it causes. It is a big issue in politics now, everyone is arguing whether or not it is actually real or that it is just a weather pattern. People need to wake up and realize that it is real, just look at the shorter winters and the warmer weather. The Glaciers are melting, crazy weather patterns are happening, so what else could it be? We have more things to worry about as a government though.
According to a chart made by NASA, it shows that the number of atmospheric carbon dioxide in these 650,000 years. For the past 650,000 years, the number of atmospheric carbon dioxide were lower than the carbon dioxide
