In the past decades, generations have been developing more and more devices that “help” us live an easier life. In today’s world people went from using sticks to light a fire to turning a switch and heating up a burner, from running around to take messages to a single drive to the post office or a single click on the computer for email, and from walking 6 hours to get somewhere to driving for only an hour. Building so many technologies no one looked into what these devices were ruining. Mind blowing facts were found that scare the scientific community. There is something that roams the air called Carbon Emissions, and scientist have found that it is almost at its peak. Carbon emissions are polluting carbon substances released into the atmosphere; carbon dioxide and carbon monoxide are two examples of carbon emissions. Carbon emissions are produces by motor vehicles. Everyday people around the world are doing an activity to increase carbon emissions. In 2008 carbon levels were over 380 parts per million and on average it is estimated that carbon levels will continue to rise by more that 2ppm every year. As more carbon emission are spread into the atmosphere it is said when the world reaches 650ppm, there will be a 4°C rise in temperature. With Carbon Emissions rising more and more each year there will be a rise in sea levels, rise in temperature, and a shortage in food supply.
Carbon emissions is polluting the air right now as we speak, carbon emissions is surrounding the Earth causing global warming. In Global Warming many things can happen and one of the causes is temperature rising. As said before when carbon levels reach 650 ppm there will be an increase in the temperature of 4°C. Rising temperatures affect the rising of sea levels. In 2007 the Intergovernmental Panel on Climate Change (IPCC) reported an issue discussing future sea level rising. “The publishing from the IPCC are unprejudiced and full contracts condensing the influence of global warming on the planet (Young, Pilkey)”. The IPCC did calculations showing the future sea level but they only included thermal expansion of the oceans and melting of mountain glaciers outside the poles. Using only those boundaries the IPCC calculated a maximum of a two-foot rise this century. The IPCC did a great job with their calculations, but because of their laziness they didn’t include the melting of the Greenland and West Antarctic ice sheets, which are two of the most important factors to the predictions of sea level rise. “Most climate scientists believe melting of the Greenland Ice Sheet will be one of the main drivers of sea level rise during this century (Young, Pilkey)”. “…Majority climate scientists confide that the major push of sea level rise in the 21st century is the defrosting of the West Antarctic Ice Sheet and the Greenland Ice Sheet (Young, Pilkey)”. With these two ice sheets melting there will be a 20 feet sea level rise and that is only including these two massive sheets.
With ice caps melting and affecting the sea level rise it will affect land being submerged under water. Sea level rising will affect homes and the people who live in coastal areas. It is recommended to, “Immediately prohibit the construction of high-rise buildings and major infrastructure in areas vulnerable to future sea level rise. Building placed in future hazardous zones should be small and movable – or disposable (Young, Pilkey)”.
The ice caps melting will cover up land concluding in a higher increase in food shortage. While the oceans rise coastal areas will be covered which is said to be the biggest piece of land where there are crops. “Building on discredit to trauma, in many portions of Asia the rice crop will be wrecked by rising sea level – a three-foot level rise will terminate half of the rice assembly in Vietnam – resulting a food crisis unexpected with the large migration of people (Young, Pilkey)”.
Rising temperatures also has an effect on the shortage of food. “A finding, in the US Journal Science came across a 90% probability that by the ending of the century, the refreshing temperatures in the tropics with the crop swelling season, would go beyond the most sizzling temperatures documented between 1900 and 2006” (Sample).” Blazing high temperatures will affect farmers’ crops, which could put half of the world’s population in a severe food shortage. According to a new study, “heated temperatures in the zone are also assumed to rise the uncertainty of drought, cutting produce losses more (Sample)”. Knowing that the temperatures will raise drastically a director, Naylor suggested developing new crops that would be able to handle the higher temperatures in the future. The biggest change in crops grown is predicted to be in the tropics because there the crops are more sensitive to the changes in the climate.
Loss of food will affect the people in a big way. “The overpower of the food shortages are believed to touch the poor, densely populate areas of the equatorial belt, where command for food is already escalating because of a swift expansion in population (Sample)”. Higher temperatures will cut crops such as rice and maize between 20 to 40%. People will have to find knew ways food can be able to grow in raging hot weather.
All of these studies have shown that we as the people who live on this planet needs to change our ways and help give back to the land, how the land has provided to us. Scientist has been studying for years and all they keep saying is bad things, so we need to cut back. James Lovelock, a scientist in Cornwall, has said, “it’s just too late for it, perhaps if we’d gone along routes like that in 1967, it might have helped. But we don’t have time. All these standard green things, like sustainable development, I think these are just words that mean nothing. I get an awful lot of people coming to me saying you can’t say that, because it gives us nothing to do. I say on the contrary, it gives us an immense amount to do. Just not the kinds of things you want to do (Aitkenhead)”. To make the future a better place to live we need to start thinking of not only how to go green, but how we can adapt to the rising temperatures, rising sea levels, and food shortage, because it is bound to happen.

Notes on the paper above: The first half of the introduction could be cut, with the paper beginning at the fifth sentence. With a short paper like this, itʻs best to begin directly and simply. There are just a few language / style problems. Some of the short sentences might be joined effectively to make longer, more graceful ones. The phrase “Carbon Emissions” should not be capitalized and takes a plural verb. However, the paperʻs introduction, in its second half, lays out a clear cause and effect road map for the rest of the paper and includes a few of the most important facts. Paragraphs in the body are connected by transitional phrases and contain lots of specific information, which is correctly cited. The paper includes all of the most relevant information in each of the articles. The conclusion effectively summarizes what has been covered and adds an additional reference that expands on the points and issues raised in the paper. The list of works cited is in the correct MLA format, for the most part. Overall , this is an excellent paper.
Effects of CO2 lead to Global Warming
Scientists warn that feedback loops caused by factors such as tropical deforestation continue to raise CO2 levels to unexpected levels. This in turn, is leading to the world’s 6th mass extinction and to the depopulation of large parts of the earth.
Global warming is happening much quicker than what people predicted and it is mainly because of the increase of gas emissions and the higher temperatures. The burning of coal was proven to be the result of higher emissions, which releases carbon dioxide into the atmosphere and causes temperatures to rise (Lydersen). “These higher temperatures are beginning to melt the arctic permafrost, which could release hundreds of billions of tons of carbon dioxide and methane” (Lydersen). The rise of carbon dioxide will also affect the growth of plants. “Warmer weather, earlier snowmelt, drought, and beetle infestations facilitated by warmer climates are all contributing to the rising number of fires linked to climate change” (Lydersen). Wildfires are also able to release more carbon dioxide than coal burning. So in the tropical forests, we need to prevent deforestation because it is more likely to be susceptible for fires than the other forests (Lydersen).
On the other hand, this is the 6th mass extinction of plants and animals. “At least 50% of all species could disappear” (Environmental News Service). The cause of this extinction is due to the pollution in the atmosphere from humans. The most important species are the genetically unique ones. For example, losing the buttercup would have a much bigger impact than losing a daisy or a sunflower because studies show that “fewer species produce less biomass than those with more species. Less plant biomass means that less carbon dioxide is absorbed from the atmosphere and less oxygen is produced” (Environmental News Service). This will eventually lead to food chains being affected, because there will be fewer plants for animals to eat, and it will interrupt the production of crops and agriculture (Environmental News Service).
The two degrees centigrade in global warming temperatures will most likely cause changes in the world leading to droughts, hunger, and flooding. The IPCC says that Africa, Asian river deltas, low-lying islands, and the Arctic will be the places that will be affected the most (Milmo). In Africa, about 350-600 million people will suffer from water shortages, agriculture could fall, and the number of species will be at risk. In Asia, 1 billion people will suffer water shortages, maze and wheat fields will fall, rice crops will drop, and flooding will occur. In Australia/New Zealand, 3,00-5,00 people will die from the heat, water supplies will drop, and annual bleaching from the Great Barrier Reef will begin. In Europe, warm temperatures will increase wheat crops, but water supplies will drop; heat waves, forest fires, and floods will increase, and new diseases will appear. In Latin America, 77 million people will face water shortages and there will be flooding. In North America, crops will increase and there will be extreme weather conditions. In Polar Regions, permafrost will increase and some communities will face loss of traditional lifestyle. There will also be land loss in the low-lying islands because of rising sea levels (Milmo). A study also predicted that in the next 10 years or less, this global warming would occur. “If warming is not kept below 10 degrees centigrade, then global impacts will occur, such as species extinctions, and millions of people at risk from drought, hunger, and flooding” (Milmo). It is therefore time to believe that there is no possible solution to this problem, and it will in fact happen.
The world will face a “perfect storm” by 2030, problems with shortages of food, water, and energy will begin to arise. “If we don’t address this, we can expect major destabilization, an increase in rioting and potentially significant problems with international migration, as people move out to avoid food and water shortages” (Sample). Northern Europe and other high latitude regions will become the major places for food production. There is a need for a renewable energy supplies, boosting crop yields, and using existing water supplies (Sample). In China, they began to build reservoirs so it will catch the melt water from glaciers, which will later be distributed into the water supply (Sample). The decrease of water, food, and energy, and the increase in flooding is a sign of global warming. There is no way to avoid globally warming because it is drastically changing the world around us slowly.

Notes on the paper above: The introduction is 3-4 sentences too short, but does not contain meaningless fluff. The paperʻs conclusion is fine: it brings in significant additional ideas that build upon what has been presented. The conclusion adds an additional article and adds citations for the facts it contributes. The paperʻs body paragraphs make good use of specific facts, which are attributed in the citations. The paragraphs need better transitions from one to the next, although specific facts are cited effectively and then attributed within text citations. The first two articles in the works cited section at the end need to be put into the correct format, with the original printed sources cited.
The Day After Tomorrow
Global warming has been among the most talked about subjects in the world for years. According to many scientists, the warming temperatures of the earth are rapidly increasing mainly due to our actions. This overwhelming issue has sadly been pushed to the point of no return. The world’s leading climate scientists are now stating that global warming is now “very unlikely to be avoided” (Milmo).
Scientists warn that the worldwide impact from global warming is unavoidable in places such as Africa, Asia rivers and deltas, and the low lying regions of the Arctic. “The rise of two degrees centigrade or less in global temperatures above pre-industrial levels as the benchmark after which the effects of climate become devastating, with crop failures, water shortages, sea-level rises, species extinctions and increased disease” (Milmo). It is predicted that in 10 years this “tipping point” will be reached. An assessment by the IPCC predicts that “up to two billion people worldwide will face water shortages and up to 30 per cent of plant and animal species would be put at risk of extinction if the average rise in temperature stabilizes at 1.5C to 2.5C” (Milmo). Even if lifestyle changes were made, the chances of reducing the risk of severe damages caused by global warming, is nearly impossible.
According to an article written by Kari Lydersen, the rate of global warming is much faster than predicted. Christopher Field, founding director of the Carnegie Institution’s Department of Global Ecology at Stanford University stated, “We are basically looking now at a future climate that’s beyond anything we’ve considered seriously in climate model simulations” (Lydersen). A large contributor to the raised concern of global warming is the increased numbers of burning coal in other developing countries. Large amounts of carbon dioxide are being released into the air due to the melting of the arctic permafrost, which holds nearly 1 trillion tons of carbon dioxide. Lydersen also states, “Along with carbon dioxide, melting permafrost releases methane, which is 25 times more potent a greenhouse gas than carbon dioxide” (Lydersen). This cycle is otherwise known as feedback loops, where the warming causes the release of carbon dioxide, leading to more warming, thus more release from the melting permafrost. “The carbon is making the oceans more acidic, which also reduces their ability to absorb carbon” (Lydersen). In the Northern Hemisphere, the snowmelt, melting of the arctic, and increase of vegetation is causing an absorption rather than reflection, which also promotes the warming temperatures. Scientists warn that feedback loops caused by factors such as tropical deforestation continue to raise co2 levels to unexpected levels. This in turn, is leading to the worlds 6th mass extinction and to the depopulation of large parts of the earth.
Environment News Service states in an article that “50 percent of all species could disappear within the lifetimes of people now living on Earth” (Environment News Service). The current negativity of the Earth’s ecosystem is largely credited to what pollution that we have all contributed to. Scientists have determined that some species are more vital in preserving the ecosystems, than others. Scientist Bradley Cardinale, assistant professor of ecology, evolution and marine biology at the University of California-Santa Barbara, states, “The Earth might well lose half of its species in our lifetime. We want to know which ones deserve the highest priority for conservation” (Environment News Service). For example, Marc Cadotte, a postdoctoral fellow at the university’s National Center for Ecological Analysis and Synthesis, discovered that, “the buttercup is a very unique species, evolutionarily. Losing the buttercup, where it occurs in grasslands, would have a much bigger impact on the system than losing a daisy or a sunflower” (Environment News Service). Losing species that are not closely related to other species in ecosystems, take heavier tolls on the Earth, rather than losing closely related species. “The more genetically distinct a species is, the more impact it has on the amount of biomass in an ecosystem” (Environment News Service). It is crucial that people are educated about which species play the most important rolls, so that we can be diligent in helping the ecosystem.
The reality is settling in for many. Global Warming is simply unavoidable. According to an article written by Decca Aitkenhead, in 1965, executives at Shell were curious as to what the world would look like in the year 2000. Most marveled at the idea of hover crafts, and mind blowing technology, but they were all wrong. When scientist James Lovelock was asked this question, he said, “It will be worsening then to such an extent that it will seriously affect their business.” Decades later, Lovelock stands correct. The abuse towards Earth that each human being has played a part in, is resulting in the desiccation of numerous species, all being affected by global warming. At this point, our actions will determine either a damaged world or a fatally damaged world.

Notes on the paper above: The introduction and conclusion are OK, but weak, lacking specific details. The introduction is too short and does not lay out a clear roadmap for the rest of the paper. The conclusion omits the most significant detail in the interview with Lovelock, the 80% decline in the Earthʻs human population in the next 100 years. The body of the paper is its strongest point, although more transitions are needed from paragraph to paragraph. Note the use of specific facts and figures.
