Hello, today I will present my presentation on the good and bad of carbon dioxide. This presentation will focus on the characteristics of carbon, global or local issues related to carbon dioxide, what science is doing to address these issues and the benefits and limitations of these scientific methods.
The name of my element is carbon. Its symbol is the letter “C” and its atomic number is 6. Its atomic mass is 12.0107. Carbon’s abundance on the earth’s crust is 200 parts per million by weight and 344 parts per million by moles. You can buy 100g of carbon for $2.40.
Global warming is the main global issue with carbon. It’s the process of carbon dioxide getting trapped in the atmosphere. The carbon dioxide is thickening the atmosphere

Carbon Capture and Sequestration is the process of reducing emissions of carbon dioxide by injecting the compound back in the ground. The process takes 3 steps:
Store the CO2 from power plants.
Transfer the CO2 in pipelines to the injection points.
Underground injection and geologic sequestration (storage of the CO2) under porous rock formations. Layers that are above are impermeable non-porous layers of rock which ensure the trapping of the CO2.
CCS is s method that can be used to lower carbon dioxide emissions while enabling low-carbon electricity generation from power plants. CCS technologies are said to be able to reduce 80-90% of emissions form factories or plants that burn fossil fuels.
One example of Geoengineering is releasing sulfate particles in the air to mimic the cooling effects of a massive volcanic eruption. By mimicking a volcano, sulfur-dioxide gas is released into the atmosphere which blocks radiation from the sun. The theory is said to work because sulfur dioxide reacts with water in the atmosphere creating sulfuric acid which scatters the sun’s radiation back into space.
Another example is fertilizing the oceans with iron or other nutrients to enable plankton to absorb more carbon. By feeding iron into the sea, you are able to grow more plankton that absorbs the carbon. You could also increase the reflectivity of clouds that already form by spraying seawater into the sky. This in turn
We've all heard about global warming as well as climate change. Climate Change is the buildup of massive amounts of man made greenhouse gases in the Earth's atmosphere. Causing the Earth's temperature to slowly rise over a long period of time.The amount of carbon dioxide in the air has increased rapidly over the years. Climate Change is a global problem and recently an issue more and more people are paying attention to.
The rising issue of CO2 emissions in the United States is a problem that we cannot ignore any longer. The main sources of carbon dioxide emissions come from the combustion of fossil fuels such as coal, oil, and natural gas. These emissions also come from everyday use of electricity, transportation and industry. Automobiles, large highways, and leaving your lights in your house on are all everyday examples that emit carbon dioxide. (EPA, "Overview of Greenhouse Gases") Carbon dioxide emissions, which have increased by 7% in the U.S. since 1990, are a dangerous and potent greenhouse gas yielded at a higher rate through coal burning than most other natural gas burning. Increased levels of carbon dioxide can lead to climate change and an increased
The Burning of fossil fuels generate 85 percent of electricity worldwide. The generation of electricity is the single largest source of CO2 emissions. Some examples of what this energy is used for are in power plants, cars, planes, and industrial facilities. Almost all industrialized nations get the majority of their electricity from the combustion of fossil fuels (around 60-90%) as well as the
Secondly, together with deforestation of the planet, the burning of fossil fuels is contributing to a measurable increase in the concentration of carbon dioxide in
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,
Global warming is the name given to the increase in the earth’s surface temperature. It is caused by the collection of greenhouse gases, carbon
“CO2 gas emissions” is a mystical term which everyone should pay attention to. C02 gas is a colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. Plants and trees are using it in the process of photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks. In other words this is the gas we need to fight with! By using fossil fuels in almost everything we do, we make a huge cloud of gas and this is warming up the world. By doing this, we cause serious damage to the nature and we may have an irreversible effect on it and the future.
Carbon Dioxide emissions contribute to the overall change in the Earth’s climate resulting in killer droughts, rising sea levels, and the disintegration of ice sheets – all which have devastating effects on the habitability of the planet. One such option to counter the effects of climate change is described in Eli Kintisch’s book Hack the Planet: Science’s Best Hope – or Worst Nightmare – for Averting Climate Catastrophe, which analyzes the controversial technique of geoengineering, or the act of deliberately manipulating an environmental process to reduce the causes or effects of greenhouse gases. Specifically, Kintisch interviews scientists and entrepreneurs from various fields to better understand the proposed geoengineering techniques
Carbon dioxide is the greenhouse gas naturally found in the atmosphere. Since the advent of the Industrial Revolution in the 1700s, humans have devised many inventions that burn fossil fuels such as coal, oil, and natural gases, which, along with other human activities such as clearing land for agriculture or urban settlements, help some of these greenhouse gases accumulate in the atmosphere that in turn trap more heat radiation in the atmosphere causing the Earth’s climate to become warmer than it would naturally (Mastrandrea). This unnatural phenomenon is termed global warming by scientists and they blame it for an increase in the Earth’s surface temperature of about 0.6°C (about 1°F) over the last 100 years (Mastrandrea).
CCS (carbon capture and sequestration) technology refers to a wide range of technology developed in an attempt to reduce levels of greenhouse gases within the atmosphere and also develop cleaner air technologies. In this way, carbon dioxide is removed from the air so that it is not immediately
Energy from the sun drives the earth’’s weather and climate, and heats the earth’’s surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the
Deforestation of tropical rainforests like the Amazon causes the amount of carbon dioxide in the air to increase, due to less photosynthesis taking place. Also when these trees are cut down they are then burnt which also adds to the amount of carbon dioxide in the air. So reducing the amount of trees cut down each year in rainforests like the Amazon will have a massive affect on the CO² levels in our atmosphere. However this may cause problems such as Brazil wanting money from logging and mining etc. therefore trees will need to be cut down.
The increase in CO2 emission is primarily caused by the burning of fossil fuels. Fossil fuels are carbon-based fuels from fossil carbon deposits, including coal, oil, and natural gas. The burning of fossil fuels is a big part of life because it powers automobiles, heats and cools homes, and generates electricity. This combustion of fossil fuels is about 90% of the total emission in the world (Greenhouse gases, Climate change, and energy). When this fuel is burned, it pollutes the atmosphere and increases the global warming process. What makes CO2 dangerous is the fact that it is nonrenewable and it warms the earth faster. CO2 emissions should be lowered because when the earth is warmed up this and other greenhouse gases increase the rate at which the polar ice caps melt, resulting in increasing sea levels and flooding. To help reduce these CO2 emissions replacing a regular incandescent light bulb with a compact fluorescent light bulb can save 300 pounds of carbon dioxide a year (Al Gore, reduce your impact at home, 1), moving a thermostat down 2° in winter and up 2° in summer could save about 2,000 pounds of carbon dioxide a year (Al Gore, reduce your impact at home, 3). Another great way to reduce CO2 emission is by switching to energy efficient appliances which can save 175 million pounds of carbon dioxide. These are one of many fantastic ways to help save the environment and drastically reduce the amount of CO2 being put into the atmosphere(Al Gore, reduce your
The Effects of Burning Carbon Dioxide The main waste product of fuel we burn is carbon dioxide, which is thought to have been the main factor in the gradual rise of global temperatures of the last hundred years. The rise is called ‘Global Warming’. The mechanism used to explain the rise in temperature is the greenhouse effect. Infrared radiation is trapped by atmospheric gases.
We build industries, we drive vehicles, and we get rid of things up like non-renewable energy sources of our world, in which they all release more and more co2 into the planet's environment. Another big way we are putting more and more co2 into the planet's environment is the "conversion of wooded area to farming use which redistributes co2 from vegetation and ground to the atmosphere"(Dharma
