Long Term Global Warming Effects Environmental Sciences Essay

Global warming is recognized to be the effect of increasing atmospheric greenhouse gases. In Australia, however, experts discover that land use/land cover change (LUCC) has potential impacts on the exacerbation of climate change consequences. To address this issue, the Australian government calls for the execution of several methods to prevent further deterioration of Australian ecosystem. Such steps are needed to reduce the harmful effects of long-term global warming in the Australian continent as represented by 15% clearing of the continent’s agriculture, hotter and drier El Niño, more frequent occurrence of drought, large-scale deforestation, and reduction in the gross population of plants and animals, and danger on human health. The consequences of ignoring this effect could have a terrible impact in the nation’s environment, economic and communities not only in Australia but also around the world. The global climate has elevated the greenhouse gases such as dioxide and ozone, which has caused global temperatures to, accelerated over the last 50 years. For example, in some cases there has been a consequential vegetation change to increased woodiness. Because of the fragility of the Australian landscape and their variable climate this effect are important to the future state of Australia’s vegetation, soil and water resources.

They decided to integrated more policies and regional natural resources strategies that will renovate their environmental issues. In addition, this will be beneficial to the vegetation and their regional climate as well as their atmosphere to fight the impact of global warming. However, they do not know to what extent such actions will have an effect.

Global climate change agenda needs to admit that climate change is a multidimensional issue that affects every population, and that LUCC must be included in global and regional strategies to inform about climate change .The authors coordinated a research that will including the role of LUCC and its dynamic interaction with increased concentrations of anthropogenic greenhouse gases. This method will require the evaluation of the capacity of reforestation, the impact of climate change at a regional scale and vegetation. Reducing deforestation in the tropics and subtropics will be the first priority. They also argue that this process requires a strong and coordinated global effort through a combination of regulatory frameworks and constructed markets to stop deforestation and facilitate reforestation. This would have extra benefits for ecosystem services. They authors conclude that the positive feedbacks to climate from land clearing appear to emphasize the impacts of global climate change by strengthen climatic extremes, such as recent droughts in eastern Australia.

Critical Review

This article provided detailed information regarding the long-term effects of global warming in the Australian continent. In particular, the article was able to identify specific causes of global warming aside from escalating atmospheric green houses gases escalation. Such events are discovered to be the result of compounded traditional land use efforts and modern land conversion practices. Furthermore, the enumeration of possible measures to address climate change in Australia marks the importance of this article in the ecological field. This article also recognizes that reducing the deforestation and improving our methods of vegetation requires strong effort to protect the planet in which we live. I agree with the authors because Global warming is happening due to the green house gases and deforestation. For example, they talk about policy implications and how we need to understand what is happening around us. I believe that by understanding and how and why the system is changing we have better possibilities by reducing the greenhouse gases and restore the vegetation. Global warning is the most urgent environmental problem the world will face in the next decade due to climate changes and other activities caused by humans. I also believe that some natural resources and agricultural sector are vulnerable to climate changes and if we do not take, action this could represents a major risk to the planet. We need to preserve our environment by putting limits to the way in which we waste products and technology that we do not need. If we implement the large-scale restoration of ecosystems, we may have a potential factor in our favor to see regional climate change and provide other ecological services such as clean air and water. However, there is not currently affirmation that such actions will change temperatures and or increase the vegetation, which makes anyone wonder if we can prevent global warning from destroying the planet.

Summary

Two of the most apparent consequences of global warming in northern Alaska are higher summer temperatures and deeper snow levels during the winter season. Alternatively, the quality of leaf mineral nutrition, as represented by Carbon and Nitrogen content, account for efficient photosynthesis, unhampered food chain, carbon budgets, soil organic matter decomposition, leaf litter, and better herbivore forage quality. In connection to this, the purpose of the article was to study and to investigate the effects of prolonged global warming effects on the leaf mineral nutrition content of tundra plants by subjecting several species of tundra plants to a long-term experiment characterized by altering summer and winter conditions. The results showed that extended global warming effects significantly affect the leaf Carbon, leaf Nitrogen and leaf Carbon: Nitrogen content of the plants. The plants were expose three different scenarios to see how each one responded to the climate conditions. The plant call dry tundra survive the clime conditions because of the moisture but the other plan call tussock tundra did not survive when it was expose to the snow.

The experiment illustrated that some species of plants leaf mineral nutrition when they are expose to different scenarios. However, the tundra field experiments have focused mostly on measuring the extent to which changes in summer or winter conditions the plants will reproduce, shortening the growing or change the composition of the vegetation. In addition, scientists recognize that caring for the ecosystem is critical to the protection of the planet against global warming. In conclusion, the experiment show that dry and tussock tundra potentially enhance gas and produce carbon when they are exposed to typical weather. This study was designed to address two questions of microbial respiration and different areas without experimental snow and how the changes in vegetation affect us.

Although they conducted a small study with limited statistical power, the findings indicate that exposing plants to snow has the potential to allow very old plant to be decomposed, accelerating the rate of CO2 increase in the atmosphere. Their results also complement recently reports by Schuur etal in 2009. In her study of tussock tundra near the Denali National Park, she finds that the plant increase due to increases in soil nutrient pools and the stimulation of plant growth. However, she says that the period in which the plant increases at the same time it losses respiration.

Critical Review

By analysis, it can be said that this article provided an experimental overview of the long-term effects of global warming on the leaf mineral nutrition content of Arctic plants. Although the settings used were manipulated, one cannot deny the significance of these findings on the future Arctic ecosystem with respect to climate change. Hotter summers and colder winters are already being experienced at present in most parts of the globe and the duration of these events are hard to quantify. Hence, the findings of this study emphasize the need to address the causes of global warming in order to minimize its effects in the future. I agree with the authors because those plants are essential to the global environment since they purify, and carry fresh water. In addition, most of the plants store carbon; absorb pollutants; and support many species of unique animals and other plants too. I think if humans put more effort, will be a decrease on the release of additional greenhouse gases and this will help communities, species and animals to survive or adapt to the global warming conditions. However, I also disagree with the authors, because they are conducting a global experiment by changing the course of Mother Nature. They propose to create a formula that could make the plants grow faster and survive any type of climate condition. I believe that could destroy the ozone layer, which will not allow life to exist on the Earth’s surface or altered the composition of the biosphere and the Earth’s heat balance. The studies show that those plants were expose to artificial conditions that were created in order for experiment to take place, but the measurements taken in Alaska that growth in trees has been stunt in recent years which mean that plants could go through the same process and consequence of a rapidly warming climate could appear faster. If the solution to global warming is to experiment more with nature then the solution will be the end.

Summary

This book contained 24 units distributed into three chapters that discuss the nature of global warming, patterns of effects, and the future of the entirety of the biosphere in response to the long-term consequences of global warming. Concerning the future effects of global warming, the author elaborated the outcomes of climate change on the biosphere, world economy, and the possibility of exploiting the Northern part of the globe as replacement of the withering habitats in the future. In particular, land and sea formations are likely to be highly affected by the fluctuating Earth temperature. Therefore, natural resources will be altered; some may be depleted, and majority will be converted. The author argues that global warning could be good for anyone who lives in the northern of the globe, which he claims, will become the new civilization. He also talks about the consequences of global warming and how the geographical locations could play an important role.He draw conclusions of warmer global climates in Iceland and the northern of the globe.

Furthermore, the author approaches the problem of how global warming is melting the sea ice in the north, which will create routes that will include the passage north of Siberia and later through the Canadian Archipelago. He shows the positive and the negatives aspect of global warming but also how this may benefit someone of the population in areas where the temperature is below normal. For example, he talks about countries bordering being closer to each other and new routes that will allow ships to travel for less time. However, he emphasizes the importance of the agreements across countries in order to reduce greenhouse gas .He also encourage the view that even in negative consequences, we need to preserve a positive attitude towards the changes that are coming. On the other hand, he argues that the warming climate and melting ice will make oil and mineral resources in northern areas easily accessible for exploitation and will make the far north comfortable for human habitation, replacing the living spaces around the central areas of the globe that will become too hot for habitation. He talks about conducting an experiment for 3 years in which he will try to expand summer at the expense of winter. In other words, he means that plants usually start to come into flower just as the snow begins to melt and with that bloom sooner then the pollinators of those plants can get to them the faster it will make the plants product their photosynthesis. That would be damaging to both of the species that he will use during the experiment. He also says that the project will confirm that people should not waste any time when it comes to saving the planet from a environmental disaster.

Critical Review

Through the page of the book, the author was able to synthesize the long-term effects of global warming. In addition, the author was able to provide a concise discussion of the consequences of climate change on the preservation of natural resources. General alteration in the ecological profile and land outline will characterize mankind’s future due to global warming. In general, this book is an effective reference on the elucidation of the profound effects of climate change not only in humans but also with respect to biosphere as a whole. I totally disagree with the author’s point of view. I believe that his perspective on global warming is more negative than positive. He describes this problem as a normal issue that we as humans have to understand that it can be a positive outcome. I have a different point of view I strongly believe that Global warming is destroying our earth and as humans, we are responsible for what is happening in the world. Global warming is gasses that are trapped in the atmosphere that are water vapors, carbon dioxide and methane gas which are the reason why many natural disaster are happening around the world lately. The author seems to believe that global warming is good for use because it could make countries closer and unify many continents that are far. He also believes that this could be a good thing for the people who live in the northern of the globe because when the ice melt the new civilization will be created. I find that statement ironic because if the ice melts there is a probability that many of the people who live in those areas will die or be hurt in some way due to the consequences of global warming. I believe that global warning is something negative for anyone, because at some point of another we all going to suffer the consequences of not taking care of the planet in which we live. I take the position that I do believe in global warming and I think it is not just scientists who should notice what is happening around the world.
