Climate Change – Fact or Fiction?

For many people, the fact that the climate is changing is indisputable. Just last week I was riding in a London black cab (not a very green mode of transportation but a luxury since I am currently 9 months pregnant!) and remarked to the cabbie how mild our London winter has been thus far – in the mid 40’s (7 degrees Celsius). He responded that when he was a school boy in the mid-1950’s it snowed in London on a regular basis. Last February, London experienced a “freak” snowstorm that shut the entire city down for the day and was considered anything but a “regular” occurrence!

Although most people agree that there is a change in our climate, when it comes to the reasons behind it, people disagree and debate the causes. Much to my dismay, I have several family members who feel that the climate change is just part of a natural cycle of climate variation. There are many people that are skeptical about global warming/climate change and will point out that Al Gore’s movie, “An Inconvenient Truth” is filled with misinformation or disputed facts. However, it is important to note that scientists agree that there is a 90% chance that the heat trapping pollution (CO2- your “carbon footprint”) has been the main factor behind the gradual warming of our planet since the 1950’s.

In the book, “A Good Life- the Guide to Ethical Living” – by Leo Hickman, it is explained that although the details are fiercely debated, there is now little doubt the among the world’s climatologists that the earth’s “carbon cycle” (the balanced cycle by which carbon is repeatedly emitted through, for example – forest fires, and then stored – by plant photosynthesis) has been affected by the CO2 humans emit. It is estimated that every year humans emit 4 billion excess tons of CO2. This excess concentration of CO2 in the atmosphere has been enough to tip the delicate balance, thus leading to the famous, “greenhouse effect” and an increase the average global

    The author, “Contoski, asserts that global warming is scientifically unproven and that the facts reveal that the earth periodically experiences changing climates” (Global Warming Is a Myth). Contoski “denies that carbon dioxide emissions have any noticeable impact on global temperatures claims that human-made emissions are insignificant when compared to carbon output of natural sources that have always been beyond human control.” (Global Warming is a Myth)…

    The global warming debate is a very hot topic. Some believe that it is real, while others do not. Even on the side of the people who think it is a real thing there is debate. Some people think that it is a naturally occurring event while others think that it is manmade. Those who believe it is manmade think that too much carbon output is the cause. This is the stand that former vice president/presidential candidate Al Gore takes in his academy award winning documentary, An Inconvenient Truth.…

    The carbon cycle is based on carbon dioxide which is a very important element because it is a part of all life. All living things are made of elements such as oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. There are such compounds that are necessary for life such as sugars, fats, proteins etc. that joins with carbon to form these essential elements. Carbon is not just in all living things; carbon is also present in the earth’s atmosphere, soils, crust, and oceans. When we look at earth as a system, these components act as storage for large amounts of carbon and when there is movement between these storages, they connect to create cycles. An example of such cycle is photosynthesis in which the carbon in the atmosphere is used to create new plant material. Over time, these plants die or decay, are harvested by humans, or burned for energy or in wildfires. All these processes, which are movements that can cycle carbon back into the atmosphere, are amongst various components within the ecosystems, and after a while releases the carbon back into the atmosphere. Humans breathe oxygen in which plants breathe carbon dioxide and releases oxygen and when human’s burn trees and other solid carbon deposits into the atmosphere, the plants that breathe the CO2 can’t keep up and the CO2 is building up. While the CO2 builds up fast since the past hundreds of years, it traps solar heat and increases the global temperature rapidly. This is not good for humans and if this chain reaction continues, who knows if humans will be able to deal with the ultimate temperature change.…

    The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that there is no connection between the two, and that the Earth is just going through its natural cycle.…

    Global climate change has been a subject of much discussion for some time now. The earth has naturally gone through heating and cooling phases in its lifetime. Most scientists agree that these changes aren’t solely the product of humans, but that the time required for natural climate change has been decreased due to humans. This has led to new problems for the earth and all of its inhabitants. According to research the earth is warming at an average of 1.2-1.4° F every 100 years (epa.gov).…

    In our society today global warming has become a topic of great debate. While many individuals are skeptical or disregard the theories regarding the Earth’s climate change, others look to the scientific literature that clearly supports the changes of our climate. According to the article “No Need to Panic About Global Warming”, global warming should be of no concern to individuals. “Many scientists and engineers who have looked carefully and independently at the science of climate” offer no evidence regarding the inflated climate changes and increased occurrence of aggressive greenhouse gasses. The article explains that carbon dioxide (CO2) is not a pollutant and is a key component to the life cycle of the biosphere. The author argues…

    The carbon cycle starts with the reservoir of the carbon dioxide in the air, the carbon atoms move from carbon dioxide through photosynthesis into atoms of organic molecules that form the plants body. These carbon atoms are then further metabolized and are eaten and turned into tissue that all organisms in the ecosystem use. Half of the atoms are respired by the plants and animals and half are deposited back into the soil in the form of dead animal and plant matter, which are eaten by decomposers and transformed back into carbon dioxide. Humans impact this cycle because we are removing so much of the photosynthetic efforts of the plants in order to support our enterprises, we are “diverting 40% of the photosynthetic productivity of land plants to support human enterprises,” (pg 67). Two examples of our harmful tendencies are burning fossil fuels which has increased atmospheric carbon dioxide “35% over preindustrial levels,” (pg. 67) and logging. These both are being used naturally by the ecosystem and the lack of these resources causes stress and strain to keep the balance. At the rate it is going carbon to complete its cycle from the atmosphere through one or more living organism and back to the atmosphere happens about every 6 years.…

Improvement in health and longevity across the lifespan also brings challenges for social work practice. At the same time, these changes are part of population aging trends consist between universal or inevitable. In addition, population aging discourse often reduces the complex dynamics of population aging to a problematic rise in older adults characterized as inactive and dependent.

    “The Scientific Consensus on Climate Change” written by Naomi Oreskes is intended to let the readers understand that there is a consensus that anthropogenic global climate change is occurring. In her essay, Oreskes states that although some groups claim there is not substantial evidence that Earth’s climate is being affected by human activities, overall, the scientific community is in agreement that evidence is quite clear. “IPCC states unequivocally that the consensus of scientific opinion is that Earth’s climate is being affected by human activities,” (Oreskes 76) which further shows how scientists do, in fact, agree on climate change. The companies, on the other hand, do not agree that climate change is caused by humans because that would adversely affect their revenue and cost them more money to replace carbon dioxide emissions with something more environmentally friendly.…

    For the last 2.5 million years, global temperature has shifted between cold glacial periods that last for around 100 000 years, and warmer interglacial periods that last for around 10 000 years. Right now we are in an interglacial period. 20 000 years ago the Earth was cold. Around 15000 years ago it started to warm up, this was the end of the last glacial period. Over the last 10 000 years the climate has been warm with minor fluctuations, however over the last 1000 years the climate has been fairly constant with small fluctuations in annual temperature. Over the last century global temperature has increased rapidly. This is called global warming; there has been a sharp rise in average temperature, 0.7oc between 1900 and 2000. The temperature increase over the last century has been very fast. There is a consensus among scientists that the changes in climate over the last century are a result in human activities (anthropogenic causes), including Al Gore, as shown in the statement which I agree with. I think the majority of global warming is due to humans therefore it is our right to try and find solutions to diminish global warming as much as we can.…

    Earth’s climate is changing. According to Climate Change Debate, “temperatures on earth have increased approximately 1.4°F since the early 20th century. Over this time period, atmospheric levels of greenhouse gases such as carbon dioxide (CO2) have notably increased.” Carbon dioxide is a gas that is formed in animal respiration and in the decay of animal and vegetable matter, it is also absorbed from the air by plants in photosynthesis. Although CO2 is often seen as something that is harmful, it is important for our habitat and the environment. CO2 is necessary because neither plants, animals, nor humans could survive, we must have plants for energy and food. Climate Change Debate says that, “the pro side argues rising levels of atmospheric…

    More than 97% of climate scientists agree that we, humans, are causing climate change by burning fossil fuels and cutting down trees. Too bad trees don’t provide us with Wi-Fi or money, we’d be planting them like crazy, unfortunately, however, they only provide us with the oxygen that we breathe. There shouldn’t be any debate about whether global warming is real or not, we know its real, there’s numerous evidence to support that, instead it should be what we’re going to do about it.…

    Global Climate Change FRQ

    Today, the world is experiencing anthropogenic global climate change. This means that there is a global climate change that is being caused by humans, which is all of us. Many people are in denial that global climate change, or commonly known as global warming, is really occurring. But, global warming really is happening and there is scientific proof. In the TED talk, James Balog explains how the arctic icebergs are the “canary in the global coalmine.” The ice is deflating and receding at a very rapid rate which is higher than it ever has. Sea level is set to continue to rise at a faster rate than over the past 40 years because of the melting ice, which is proof that global warming is really happening. Also, carbon dioxide is at an unprecedented level not seen for at least the last 800,000 years. It is released through natural processes but also through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by a third since the Industrial Revolution began. The carbon dioxide levels are directly related to the population of the world.…

    According to the article Global Warming on NASA’s website, published by Holly Riebeek on June 3, 2010, between 1906 and 2005 the Earth’s average surface temperature rose between 1.1 to 1.6 degrees Fahrenheit. This is not the first time the Earth’s climate has changed. The climate has experienced changes since the beginning of time. Small differences that occur in the Earth’s orbit cause a somewhat different temperature. The sun is the main ingredient when it comes to temperature. In the past, the Earth’s orbit has changed, causing a slight change in temperature (Riebeek 1). This is not what the controversy sweeping the world. The problem is the more drastic change recently because of humans. The Earth has a natural heating mechanism called the Greenhouse Effect. The Greenhouse Effect is a necessary part of human existence. However, the problem is humans are increasing these greenhouse gasses by burning fossil fuels, such as oil, and burning down forests, increasing the carbon dioxide level (2). Without all this, humans would face an inevitable downfall.…

    The debt over burning fossil fuels and the impact it has caused on climate change as been discussed over years without answer as to say if the gradual warming of the earth is a natural process or if human activity has added to the acceleration of climate change or is the key behind it. Evidence of this is the hockey stick debt as temperature rise rapidly once humans became developed. One thing we do know is that there are many natural events that possibly could accelerate global warming but also many human factors to. Thus making climate change hard to blame on human activities like burning fossil fuels and or nature.…
