Carbon dioxide

current earth’s atmosphere is made up of Nitrogen (N2), Oxygen (O2) and a small amount of other gases. However the early earth which was formed 4.5 billion years ago was made up of Ammonia (NH4) and Carbon Dioxide (Co2). 4 billion years ago the world was covered with volcanos. The volcanoes released Carbon Dioxide (CO2) methane (CH4) and water vapour. The oxygen levels were 0.000%, also meaning no oxygen. 3.2 billion Years ago life of bacteria was forming and increasing. This made food by…

The two major processes that drive the normal functioning of the carbon cycle are photosynthesis and cellular respiration. Photosynthesis is the metabolic pathway that takes raw materials and converts it to sugar. Photosynthesis takes place in the leaves, specifically in the chloroplasts of the cells of plants. Photosynthesis also occurs in plants, green protista, and prokaryotes. There are two phases in photosynthesis, the light dependent and the light independent reactions. Cellular…

because of greenhouse gasses, including carbon dioxide 2. However, carbon dioxide is essential for the photosynthesis of plants, allowing plants to be successful autotrophs by using carbon dioxide, water, and energy from the sun to produce glucose and oxygen. One of the main sources of photosynthesis in a plant is in the leaves. When leaves decompose they release the carbon dioxide used in photosynthesis. It is important to figure out how much carbon dioxide is emitted from leaf decomposition in…

called the Medulla Oblongata and the Pons regions. The medulla sends signals to the muscles that is involved in breathing, and the pons controls the rate of breathing. These two regions in the brain can affect or have negative effect on oxygen and carbon dioxide levels in the bloodstream. The body responds to low oxygen when there is there is dilation of blood vessels, which decreases blood pressure. This is also known as vasodilation. Thus, the blood vessels relax and widens enabling greater…

nuclear age and a period of unprecedented climate change, scientists have a special responsibility, once again to inform the public and to advise leaders about the perils that humanity faces.” As is well known, one of the most important thing can be carbon dioxide which we release into the atmosphere when we burn fossil fuels’ oil, coal, and natural gas to generate electricity, power our vehicles and heat our homes. Human activities produce greenhouse gases and these gases are the key causes of…

higher than have ever been recorded. Carbon Dioxide emissions, fossil fuels burning, and deforestation have caused 2015 to be the hottest year ever recorded. The rise in heat has caused water in third world countries to become scarce and wars to occur. Global warming is a colossal issue that affects the environment, the world, and mankind, and if it is not stopped soon, the results on the Earth could be disastrous. Global Warming has put an enormous “carbon footprint” on Earth, although some…

of the greenhouse gases released as individuals burn fossil fuels. Global warming is because of the enhancing greenhouse gases emission and build-up in the Earth's environment. The gasses that have an impact on the atmosphere are water vapor, carbon dioxide, dinitrogen-oxide, and methane. Very nearly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. In the other 70 percent, most are consumed by the land and ocean, and the rest is absorbed by the…

The carbon cycle does not necessarily begin at a certain point, but instead plants pull carbon (in the form of carbon dioxide) from the atmosphere to make food through a process called photosynthesis. Through food chains, animals get carbon from the plants and other organisms they feed on. When these plants and animals die and decompose, the carbon goes back into the soil. Some of the carbon is submerged deep into the ground and eventually forms…

weather patterns throughout the planet. What causes the actual warming of the planet starting from the atmosphere is the greenhouse effect. The greenhouse effect is the concept of the planet retaining heat from greenhouse gas compounds such as, carbon dioxide, methane, nitrous oxide. These gases contribute to form a protective shield around planet Earth, however the more imbalanced this shield becomes with the greenhouse gases, the more detrimental the greenhouses gases become to Earth’s vast…

encompasses a multitude of physical systems ranging from the atmosphere to the carbon cycle to the cryosphere and the ocean. This brief provides an introductory overview of the current state of climate science, using data on historical and future trends from recent scientific literature. It explores the methodologies of scientific research on climate change; the role of the atmosphere and greenhouse gases (specifically carbon dioxide) in climate change; the effects of climate change on the ocean…
