Recommended: impact of deforestation
Imagine? One day you wake up and all you can see and smell is smoke. Do you think this will be good for you? Good for our planet?. However, even though some people believe greenhouse gases have nothing to do with climate change, people should take more responsibility for the planet because the deforestation of land and the burning of fossil fuels is the principle cause of climate change. The warming that is evident is the instrumental temperature record is consistent with a wide range of observations, as documented by many independent scientific groups. The climate system can warm or cool in response to changes in external forces. Therefore, some scientist say that human generated greenhouse gas emission is too small to substantially change …show more content…
Most people do not think about global temperatures, but local ones. Therefore, climate change affects ecosystems, not just through increases in the mean, but also through changes in the extremes. Earth is already showing many signs of worldwide climate change. Even more, scientists are now able to say that climate change increases the risk of a particular weather pattern by a measurable amount and, in any case, that a particular episode is almost impossible to imagine without global warming.
Nine of the eleventh hottest years in the 20th century have occurred since 1985 which is not consistent with a natural trend. Glacier Shrinkage is occurring at a much faster rate than can be explained by natural trends. Even when the heat effects of volcanoes and other misleading weather phenomena that would make the temperature of the earth seem higher than it actually is being taken out of consideration studies show that the surface temperature of the earth has been increasing at a rate of 0.17 degrees Celsius per decade. These figures are not consistent with a natural trend, and, when one considers the tens of thousand of years in which humans have inhabited the earth, and that humans have really only started burning fossil fuels heavily since the industrial revolution, and the fact that the world’s population is only going to increase, this number is dauntingly

What is also becoming increasingly clear is the effect that forests have on the climate and the climate has on forests, and how changes in one system will affect the other. Losing forest makes it worse. Clearing forests also releases large amounts of carbon dioxide. Worldwide deforestation means we don’t have as many trees to absorb the extra CO2. This means more of it stays in the atmosphere, trapping more heat. Forest are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. The biggest driver of deforestation is agriculture. Farmers cut forest to provide more room for planting crops or grazing livestock. Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in process known as “ slash and burn” agriculture. Therefore, not all deforestations is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees. Deforestations has many negative effects on the environment. The most dramatic impact is a loss of habitat for million of species. So seventy percent of Earth’s land animals and plants live in forest, and many cannot survive the deforestation that destroy their homes. A more workable solution is to carefully manage
Mankind’s industrialization of the world has caused a drastic increase in temperature. This rise in temperature is caused by solar radiation remaining in our atmosphere because of gases produced by humans through the burning of fossil fuels, land clearing, agriculture, and other human activities. These gases block the radiation from escaping into space therefore warming our planet. The result is raising of ocean levels, extinction of species and threatening of children’s health because of disease and less freshwater to drink. While many view climate change to be a more natural occurrence than others do, scientists have proven the average temperature rise of the Earth between 0.4 and 0.8 °C over the last 100 years.
Climate change is considered a controversial topic. Although scientists have been studying the issue, there are many citizens that are still not fully educated about it. Therefore, there are people who support scientists in their results, and there are people who deny the scientists’ findings as propaganda or exaggerations. This is the same issue even in politics, where the two main parties, Democrats and Republicans, have opposing perspectives on climate change. One can really tell just by looking at their approach to the issue, especially their tone and diction. The republican candidates doubts climate change, and when the topic is brought up during an interview, the republicans flatly deny it with no further discussion. They do give some
Over the last few years almost everyone has heard that the earth is warming. Also, almost everyone has heard the pleas to go green and reduce carbon emissions, led by former Vice-President Al Gore. Even though there is not a truly accurate definition of global warming it can be roughly defined as a rise in average global temperature according to Laurence Pringle’s book Global Warming Assessing the Greenhouse Threat (19). Global Warming Assessing the Greenhouse Threat also bring up that the average temperature data that scientist are using only goes back to 1860 giving scientists today only 150 years of temperature data. Also, with this current warming, even with humans contributing to the rising average global temperature, scientist today do not fully understand all the complexities of the atmosphere (Pringle 19-21). According to another book by Mr. Pringle, Global Warming the Threat of Earth’s Changing Climate, scientists predict global temperatures could rise from two to six degrees Celsius by 2050 (33). Despite these predictions historical and new information show that scientist are incorrect that global temperatures will forever continue to increase. Global warming and the rise in global temperatures is due to humans burning fossil fuels and overconsumption of products, as well as natural cycles changing slightly and other natural phenomenon; however, this warming will eventually lead to global cooling.
Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?
Global climate change and its apparent effects have been the subject of much discussion for a number of years. It is often claimed that this change is too advanced and the damage caused by it is irreversible, meaning that any efforts by us to undo this are in vain. Although I agree that our planet has become unalterably changed, I don’t entirely concur that this change is now completely beyond repair.
Forests play a critical role in the carbon cycle on our planet. When forests are cut down, not only does carbon absorption cease, but also the carbon stored in the trees is released into the atmosphere as carbon dioxide. If the wood is burned or even if it is left to rot after the deforestation process, this would cause the carbon dioxide to be released too. Cutting down forests will cause a decline in photosynthetic activity. Photosynthesis is the process where plants and trees take in carbon dioxide and converts it to food. Once converted to food, the tree, or plant, will releases oxygen. Having a decline in photosynthetic activity will result in the atmosphere retaining higher levels of carbon dioxide. As carbon dioxide builds up, it produces a layer in the atmosphere that traps radiation from the sun. The radiation converts to heat which causes global warming, which is better known as the greenhouse effect. Small crops, such as corn or plants, draw in small amounts of carbon dioxide and release oxygen, however forests store up to one hundred times more carbon than farmer’s fields that are the same area. When
“It’s a well-kept secret, but 95 percent of the climate models we are told prove the link between human CO2 emissions and catastrophic global warming have been found, after nearly two decades of temperature stasis, to be in error,” writes Maurice Newman, chief business advisor to Australian Prime Minister Tony Abbott (Dunn). With this bold and senseless declaration, Australia joined the community of global warming denial and thrust itself onto the international stage to become yet another participant in the dramatic environmental debate about climate change. Climate change, like no other global argument, has been an emotionally charged subject since it was first introduced at the end of the 19th century. It continues to polarize countries
There’s a lot of discussion about the issue of climate change which can make people feel like their actions to stop it are useless, but there is hope for the future. Young people today, such as college students, are very busy and have other things on their minds. However, there are simple ways to make a difference that could even save you money. Stopping climate change doesn’t need drastic changes to one’s daily routine or even help from the government because if everyone does something small then the impact will be significant.
Climate change can affect everyone in many different ways, take for example the summertime heat. Think of the hottest day you’ve ever experienced throughout your life, the hot sun beating down on you and the only thing you’re thinking of is “how long do I have to deal with this?” Well, with the current effects taking place due to excessive amounts of greenhouse gases and use of non renewable resources going on, after a certain period of time that weather will be a whole 12 degrees hotter than it is today. So imagine that same day, the heat you had dealt with, except a whole 12 degrees even hotter, that is the kind of heat we are going to be dealing with if we do not change the way we are handling things. If for some reason we don 't stop, then we should at
Climate change. The two letter word so feared by scientists, so ignored by the average human being. What is it that makes scientists fear this phrase so much? For the concept of “climate change” has been seen throughout the history of the earths existence. For centuries, our climate has fluctuated through increasing and decreasing amounts of atmospheric carbon dioxide and climatic cycles. So what is the big deal? The problem, and the reason why this concept instills fear directly into the core of scientists is the rate at which over the past 1,300 years atmospheric carbon dioxide levels have risen. This unnatural increase in atmospheric carbon dioxide, due to the immense amount of anthropogenic burning of oil and coal, affects the transfer
Climate change, or global warming, is the gradual increase of the temperature of the earth Climate change has been a topic that has been talked about for awhile now If it is happening, if it is not, if humans cause it, and if it is happening naturally Humans could be causing it by the many things we do, but the earth could be going through natural cycles which is causing climate change. There is evidence to support all of these arguments. Even scientists are having arguments about whether it is occuring or not. In 2010 Climate Depot released a report featuring more than 1,000 scientists, who disagree that humans are primarily responsible for global climate change. I am going to tell you everything that you need to know about climate change.
The Environmentalists claim the science is settled, and that any actions taken to prove otherwise will be unfruitful. They do this to turn public attention away from the fact that much of their data is purposely taken out of context, manipulated, or made up in order to prove that Manmade Global Warming exists. In fact, there is more evidence showing that the rise in temperatures may be due to solar activity or part of the Earth’s natural climate fluctuations, than to support that it is caused by greenhouse gases generated by humans.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
Even if the reason of climate change may be the natural cycles, we humans are the major determinant to it. The huge amount of greenhouse gases in the atmosphere is causing the climate change and this amount is rising day by day, as a result of our actions. Greenhouse gases, like carbon dioxide, generally absorb and emit the heat in the atmosphere to keep the Earth’s climate habitable. However, as we continue to burn fossil fuels, this habitable Earth’s temperature will blow up, and as a result, some species will die out due to various problems which are caused by climate change. According to EPA (Environmental Protection Agency), the most obvious consequence of climate change is the rising sea levels, which will cause some seashore habitats to become unavailable to live to its species.
