Controversy Concerning Carbon Dioxide Emissions and Its Effects

So not only were the levels of CO2 in our atmosphere the highest recorded in more than 800,000 years, they were also in excess of the 350 parts per million (ppm) “cautionary threshold” put forth by Dr. James Hansen and other climate scientists in 2008. In fact, CO2 measurements on Mauna Loa in the spring of 2014 exceeded the “extreme danger” Cclimate Cchange threshold of 400 ppm from which some scientists have said that recovery is not possible.

Dr James Hansen’s argumentative essay, “A Solution to the Climate Problem,” discusses his premise that it is imperative for humankind to deal with carbon dioxide emissions, which he believes needs to be phased out by the mid-21st century. He begins with the current paradigm in government efforts to reduce carbon dioxide emissions and claims that so far it has been a lot of talk and action in the other direction. Dr Hansen argues that while governments pay lip service to agreements such as the Kyoto Accord, they are going full steam ahead with projects that will result in increased carbon dioxide emissions, such as going forth with coal-fired power plants, coal-to-liquids, hydraulic fracturing, and tar sands oil extraction. Dr Hansen believes

In recent years , there is a colossal upsurge in the number of environmental concerns with climate change being a pivotal one. Although convergent efforts, be it an individual , company or a government, are made to ease this concern. I think government play a vital role in this regard.

According to “Target Atmospheric CO2: Where Should Humanity Aim?”, a scientific article written by scientists involved with National Aeronautics and Space Administration (NASA), Columbia University Earth Institute, Boston University, Yale University, and many more prestigious programs and universities, the highest limit for CO2 that is still considered “safe” for the public and the planet is 350 parts per million(ppm) (Hansen, Sato, Kharecha, Beerling, Berner, Delmotte, Pagani, Raymo, Royer, and Zachos 1). However, the atmospheric levels of CO2 have remained higher than 350 parts per million since January of 1988, with the most current level being reported at 401.30 parts per million in June 2014 (Keeling, Piper, Bacastow, Wahlen, Whorf, Heimann, and Meijer 83-113). The Intergovernmental Panel on Climate Change (IPCC), well-known as the leading organization for the assessment of global warming and climate change, conducted an assessment report in 2007 that stated, with a 90% level of certainty, that the rising temperature of the Earth is a direct result of human activity and is also heavily linked to industrial processes (Solomon, Qin, Manning, Chen, Marquis, Averyt, Tignor and Miller 1-996). Even more disappointing, according to the

This decrease has been not only increasing the sea level at an unnatural rate, but also endangering many arctic species. As these species are forced to change their hunting habits, the native villages are starving themselves, knowing only how to hunt the animals in the pattern they moved before. While the polar ice caps melt more and more, the purity of the water is negatively affected which, in turn, directly affects the air purity, too. According to experts from the Environmental Protection Agency, greenhouse gases are emitted mostly from electricity, industry, and transportation (epa.gov/climatechange). Even though the amount of greenhouse gases have been rising very unsteadily the past 100 years, these gases have been and always will be crucial to our survival on this planet, as long as there is a steady balance between greenhouse gases and carbon dioxide. When we emit carbon dioxide into the air, the atmosphere becomes more acidic; this causes the greenhouse gases to become further amplified and more likely to break down the ozone layer, which in turn pollutes the air even further, creating an endless

Have you ever wondered how many people there are in the world? This beautiful place called earth is home to billions of humans, and human-kind is not alone. Although at times we may forget that we have several different species living with us, not only do different species live with us but they are part of the circle of life that is the root of our existence. For many years’ people have been releasing excessive amounts of CO2 into the earth, with little to no consideration of the effects it may have on surrounding environments. Exploiting natural resources to leave nothing behind except for oil spills and other environmentally dangerous components. Corporations need to be held to higher expectations with more regulations, there needs to be a government that will enforce these regulations. Who decides our government? People do, local communities vote for who runs their city, state, and country. Communities can help spread awareness and demand cleaner energy, stricter laws, and reduce their carbon footprint.

Climate change, specifically in reference to C02 Emissions released by human use of fossil fuels and their consequential effects on the environment, is perhaps one of the most pressing issues we, not just as Americans, but as human beings face in our lifetimes. Though it may sound like a sensationalist statement the facts are hard to deny. In May of 2013, the National Oceanic and Atmospheric Administration

Values higher than today have occurred only millions of years ago due to massive forcing acting at a global scale, such as the immense and ‘sudden’ (from a geological perspective) release of methane-clathrates of 55 million years ago which drove CO2 concentrations up to 2000 ppm (marking the onset of an era, the Eocene period). According to most observations and climate models available today, current concentrations cannot be justified by natural causes alone without considering human influence. The annual average concentration growth rate of CO2 was larger during the last decade (1, 9 ppm) than it has been since 1960, when continuous direct atmospheric measurements begun (1, 4 ppm per year, although with year-to-year variability). Specifically,

Global warming has been a controversial topic for years and some have even denied its existence; however, as more studies are being published every day in regards to our changing climate, it is hard to ignore this growing issue and how humans contribute to it. The term greenhouse gases refers to the group of gases that are primarily responsible for global warming and chief among these gases is carbon dioxide. Rising carbon dioxide levels can be attributed to a combination of burning fossil fuels such as coal, natural gas, and petroleum as well as deforestation in general ( Source A). To slow the effects of global warming, it is important for leaders in our society to consider their greenhouse gas emissions, especially carbon dioxide, and make

Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,

Climate change has been a topic of debate for decades. Scientists support climate change is happening with hard scientific evidence whereas the people who oppose climate change have evidence which is mainly opinion-based. This report will cover what climate change is, why climate change is happening, the science that supports climate change, the different views and opinions on climate change, the effects of climate change around the world and particularly the effects in New Zealand, my opinion on climate change and my conclusion on the issue.

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes

   The United States releases twenty tons of carbon monoxide per person per year. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment. Everyday fuel is burnt by cars, airplanes, large factories and manufacturing plants. This is causing a very large and deadly problem for our environment. When gases used on earth are released into the atmosphere they act as a blanket and trap radiation that is then redirected to earth. This concept is called the Greenhouse Effect (Bad Greenhouse, 1).

The rapidly increasing amount of carbon dioxide may be one of the factors that cause climate change. As Hillman states, “Concentrations of carbon dioxide in the atmosphere are increasing, and have done so since the Industrial Revolution.” An atmospheric CO2 concentration, research shows that there is a dramatic increase from 280 parts per million (ppm) in 1750 to 373 ppm in 2002, a rise of the third. Furthermore, the linear chart demonstrated the trend of annual global CO2

The world continuously faces a variety of threats every day, from natural disasters to terrorist, but one threat that society predominately contributes to all on their own, is climate change. There are many feasible explanations for the global threat of climate change. These explanations include but are not limited to, the act of deforestation to the rainforest and other trees, green house gas emissions, and sulfate aerosol, which cause poor air quality.
