Through the research I’ve done on global warming it appears to me that there is no problem with it at all, and that there is nothing to worry about. We need to accept that fact that global warming is actually helping the human race in many different ways. For examples the environment is warming up, the ocean levels are rising, and the increase of carbon dioxide are all benefits to the environment and economy. It’s almost as if global warming is turning the earth into a tropical paradise.…
Did you know that by our everyday habits and choices, the average American puts out 22 tons of carbon dioxide (CO2) per year? Experts studying the recent climate history of the earth agree now that global warming is occurring at a precipitous rate, and human activities are the dominant force driving the trend. Our smokestacks, tailpipes, and burning forests emit CO2 and other gasses that add to the planet’s natural greenhouse effect, allowing sunlight in, but preventing some of the resulting heat from radiating back to space. Many climate experts say that without big curbs in greenhouse gas emissions, the 21st century could see temperatures rise 3 to 8 degrees, weather patterns sharply shift, ice sheets shrink, and seas rise several feet. The problem of global warming seems overwhelming, but there is a lot you can do to help. Reducing your personal share of global warming emissions is easier than you think.…
The most vulnerable impact of climate change in Canada is the production of forestry. Every year, almost 6 billion trees are cut down leaving not only pollutants of factories that produce greenhouse effects, but leaving ecosystems destroyed and animals vulnerable. In addition, as a result of human activities in Canada-that produce immense amounts of CO2-causes ice sheets and alpine glaciers to melt- taking a substantial toll on Arctic ecosystems. Moreover, the rising levels of CO2 affects Canada's weather and climate patterns as some regions may experience more extreme heat while others may cool slightly. Flooding, drought, and violent storms and other extreme weather events are some of the consequences and issues that affect our society.…
The U.S. is a major contributor to global warming because it produces 25% of the world’s carbon dioxide. Proposed laws to reduce carbon emissions in the U.S. are urgently needed and should be enacted immediately to save the planet." I agree that we need to reduce carbon emission standard. I have discovered that the cause of polar bear drowning is due to global warming. I am glad that congress has passed the clean air act in 1970's.What worries me is how much amount of hydrocarbon is poluting the air today? I have discovered that VW(Voltz Wagon) has engaged in a diesal scandal, which violate the clean air that is still in…
According to the writer, as the “world's two biggest polluters” the agreement between the U.S and China represent a major step toward addressing climate change.The writer reports that climate change is a global issue that need the coordinated effort of countries around the world. The writer also includes a speech by His Holiness Pope Francis, who said that "Climate change is a global problem with grave implications." This article is important to my research paper as it provides up to date information on the status of measures taken by countries in the effort to fight global…
The carbon tax could positively influence our society environmentally to further strengthen our future. It encourages alternatives such as public transit, carpooling and even biking due to the elevated gas prices. The tax will also intend for households to not take their electricity for granted and utilize it as a scarce resource. “It increases social efficiency by making people aware of the full social cost” (Pettinger Paragraph 9). This relates back to the Paris Agreement which was signed by the federal government of Canada to reduce greenhouse gas emissions and a carbon tax will be of use in order to achieve the goal. Canadian policies will create incentives to develop low carbon and technology for countries investing in renewable energy. According to Hodgson, “The Conference Board of Canada is conducting research to understand better the low-carbon business and trade opportunities for Canadian firms. Unfortunately, many European countries—and now China—are more advanced in their…
Climate Change is a worldwide phenomenon which affects the regular conditions of the environment. Historically, there have been several conventions, like the Kyoto protocol, in order to address this problem. However, only since the Paris Agreement, countries have really committed to take actions to mitigate climate change. In fact, Canada has presented a strong position, establishing a main target with different approaches to counteract the problem. However, the new regulations may not be adequate for all the provinces, showing the need of better policies that combine coherently the economic necessities of each province with efficient actions against climate change.…
The largest environmental issue that is effecting the global climate change specially in Canadian society would be global warming. Although global warming and its effects are taking place all around the world, a huge part of the ramifications that we are seeing are taking part in Canada. Global warming has lead to many environmental problems including the melting of the north pole and northern areas as well as forest fires and animal extinction. All of these sub-topics, although speaking specifically to Canada in this research essay, these environmental problems will not only happen throughout the rest of the world but some will possible even create a domino effect.…
Global Warming is an important issue for us to address because it’s hurting our environment. Deforestation leads to the extinction of animals like Orangutans. Pollution leads to a whole in the o-zone layer which then leads to more sun rays coming into earth and warming up the planet. This causes melting ice-caps and rising sea levels which might flood land at some point. There are too many people living on this planet for too many people not to be helping each other take care of our planet. Simple things such as purchasing…
The Kyoto Protocol, which took effect on February 16, 2005, aims to reduce the amount of greenhouse gas emissions around the world. The debate whether the issue of climate change is valid or whether it is an exaggerated theory is still ongoing. Given that the Kyoto Protocol raises economic concerns and that it lacks overall effectiveness, Canada and businesses in general should not be in favour of it. This is in part because of the treaty’s conditions and partially because of the actions of other nations regarding the treaty. In order to demonstrate the lack of effectiveness, the economic impacts must first be discussed.…
For the past decade now there has been a long ongoing controversy, this controversy being this issue of global climate change. It has been a subject many people have been aware of yet few have actually talked about with the general public, as a result is has become one of the most undermined, yet widely discussed issues being held today amongst primarily scientists. Although scientist heavily debate on the subject, making suggestions on what needs to be done and pointing out the causes for climate change; we as a group need to take action in finding out what is happening to the Earth. It is only educating the general public is the only way we can come closer to reversing the damaged caused by global warming and climate…
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.…
