A Dangerous Atmospheric Devation Is The Best Test Confronting Our Planet

When trees are burned, CO2 is relinquished. The burning of astronomically immense areas of trees is known as deforestation. Human activities integrate more CO2 into the atmosphere through activities like the burning of fossil fuels. The guiding question of this investigation is, “Which carbon cycle process affects atmospheric carbon the most?” The researchers initially wanted to learn 2 things. First, the researchers wanted to learn how much carbon engenderment there would be if they incremented the amount of fossil fuels burnt by a certain amount. The researchers also wanted to learn how much carbon engenderment there would be if they incremented the amount of deforestation.

An example of a catastrophic climate change is a period known as the “Younger Dryas,” an epoch in time when the mean global surface temperature dropped drastically in a couple of decades and lasted for one millennium. Although the circumstance of the Younger Dryas is quite different compared to the present, it shows how cataclysmic a drastic climate change could enforce. Two important or major definitions presented in the work are mean global surface temperature and (global) climate. Mean global surface temperature is defined as “average of the air temperature measured at the land surface and of the surface water temperature measured over large bodies of water” (Jordan, 2006, p. 159). As for global climate, according to Jordan (2006), “the average of the global weather…over a time interval appropriate to the rate at which the climate is changing” is the best definition. These two terms appear frequently throughout, which shows the significance of comprehending the meaning as it relates to the argument and explanation.

Climate Change- Climate is a long term change in the Earth's weather, especially due to an increase in the average atmospheric temperature. According to research, it was discovered that the Earth's temperature rose by 0.6 degrees Celsius (C) and predicted that the sea surface temperature may rise by up to 1 degrees C over the next 50 years. Unfortunately, carbon dioxide and methane gas levels are the highest they have ever been for the last 420000 years. These two gases with water vapour, nitrous oxide and halocarbons create the five predominate greenhouse gases, effecting the environment greatly. Furthermore, it is evident that an average person release 4 metric tonnes of carbon dioxide per year. Due to this fact, carbon dioxide

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).

Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,

Earth is an immeasurably complex planet, and the processes that make it so are equally as intricate. It is this same intricacy, however, that makes the Earth so vulnerable to even the slightest variation in overall temperature or change within the gases that which compose the atmosphere. What We Know About Climate Change by Kerry Emanuel aims to address this issue of Earth’s vulnerability head-on as it suggests the plausible causes for the undeniable planetary warming observed in the last century all the while proposing pragmatic solutions to discontinue the unnatural processes credited with the abnormal warming.

As carbon dioxide is a greenhouse gas, increased concentrations of it have led to an amplified greenhouse effect. More solar infrared radiation is re-emitted and absorbed by the Earth, causing surface temperatures to rise. Therefore, the density of the surface waters will decrease, which means there is a greater

For over a hundred years, scientists have been carefully gathering and verifying data on the earth's temperature. The latest data reveals some striking trends:All 10 of the warmest years on record have occurred in the last 15 years The 1990's have already been warmer than the 1980's- the warmest decade on record The global average surface temperature has risen 0.5 degrees (site source)For the first time ever, the Intergovernmental Panel on Climate Change, the authoritative international body charged with studying this issue, concluded that the observed increase in global average temperature over the last century "is

In addition, human activities like deforestation may increase the amount of carbon dioxide in the atmosphere. This is because forests help in carbon sequestration, which reduces the amount of carbon dioxide in the air. It follows then that clearing such tress will increase the amount of carbon dioxide since carbon sequestration will not occur (3). The man-made theory of climate change also explains that when these harmful gasses reach the atmosphere, they form a blanket, which traps heat in the atmosphere. This trapping of in the atmosphere is the phenomenon that causes the planet to get warmer, hence the term global warming (Sharma, 4).

The report concludes, again with “high confidence”, that anthropogenic (human caused) warming has had a discernible influence on many of our planets physical and biological systems. While there are limitations and gaps in the knowledge available, particularly from undeveloped countries, the knowledge available allowed the group to attribute most of the observed increase in the globally averaged temperature since the mid-20th century to the observed increase in anthropogenic greenhouse gas concentrations. The analysis was necessarily limited in the number of systems and locations considered. In addition, natural temperature variability is larger at the regional than at the global scale, thus affecting identification of changes due to external forcing and at the regional scale other factors such as land-use change and pollution, are an environmental

So, is the temperature really rising? This simple answer to this question is “Yes.” According to Watson, we now have strong evidences that the climate is changing and that human activities were the primary cause of the changes during the 20th century (24). He asserts that the temperature increase in the 20th century was greater than that for any other century during the last 1000 years and the temperatures now are warmer than at any time during this period (26). Johns acclaim that the rise in CO2 levels from 280 parts per million around 1700s to 380 p.m. Today is the major factor

The Wilderness Society’s Governing Council states that “No other ecosystem in the world can store as much carbon as do these forests, and it’s a capacity they have not yet begun to reach” (Bert5). Trees are very important to all of the living species. The cutting down of the trees is now nearly 4 billion trees or 35% of the total trees cut around the

The atmosphere on the Earth is evolving. Ice age is interleaved with the a worldwide temperature alteration. In the present age, the temperature of the Earth's atmosphere framework proceed quickly increment and it prompts an unnatural weather change. An unnatural weather change is the procedure of progressive development of normal yearly temperature of the air of the Earth and World sea. The normal temperature on the Earth was expanded by 0.6C. There are different reasons of a dangerous atmospheric devation, for example, human exercises, regular occasions, expanding of gasses, for example, carbon dioxide in air and sun oriented action. Almost 200 nations have marked Kyoto Protocol and they should lessen four nursery gasses, keeping in mind the end goal to battle with a dangerous atmospheric devation. There are a few points of view about impacts of an unnatural weather change on condition. In this exposition will be viewed as the effects and outcomes of a dangerous atmospheric devation . All the while, it will be cleared up that there are sure and negative effects of an unnatural weather change.

According to the Urban Forestry Network, trees improve our air quality, and reduce energy costs. The heat from the earth is within the surface and atmosphere due to high levels of carbon dioxide with other heating gases. It prohibits the heat from entering the space. "Therefore, trees help by removing (sequestering) CO2 from the atmosphere during photosynthesis to form carbohydrates that are used in plant structure/function and return oxygen back into the atmosphere as by product. Roughly half of the greenhouse effect is caused by CO2. Therefore, trees act as carbon sinks, alleviating the greenhouse effect". This clearly state trees benefits a lot into the environment and the atmosphere. Trees reduce the energy cost every year, “Trees reach their most productive stage of carbon storage at about 10 years at which point they are estimated to absorb 48 pounds of CO2 per year. At that rate, they release enough oxygen back into the atmosphere to support two human beings. Planting 100 million trees could reduce an estimated 18 million tons of carbon per year and consequently save American consumers $4 billion each year on utility bills". In the quotation, the planting of trees, the more oxygen produces in the atmosphere.
