Despite 1 in 2597 of Earths atmosphere (0.039%), Carbon dioxide is substantial to sustaining life on Earth. Since carbon dioxide and not just Carbon is my research topic, I shall explain only how Carbon effects people. Discovered by Joseph Priestley and Antoine Lavoisier Carbon in the Carbon cycle is exchanged within the biosphere, pedosphere, geosphere, hydrosphere and atmosphere of Earth. Naturally in an indefinite cycle, plants perform photosynthesis using Carbon dioxide, water and energy from the sun; in turn Animals reverse the process in cellular respiration allowing the cycle of carbon to be recycled to sustain life on Earth. Carbon cycle is exchanged within the biosphere, pedosphere, geosphere, hydrosphere and atmosphere of Earth.Carbon dioxide leaves during photosynthesis, entering the terrestrial and oceanic biospheres. Carbon in the atmosphere dioxide also dissolves into large bodies of water such as Oceans, and lakes; as well as in precipitation such as raindrops in the atmosphere.Carbon dioxide leaves the atmosphere through photosynthesis, thus entering the terrestrial and oceanic biospheres. Carbon dioxide also dissolves directly from the atmosphere into bodies of water (oceans, lakes, etc.), as well as dissolving in precipitation as raindrops fall through the atmosphere. When dissolved in water, carbon dioxide reacts with water molecules and forms carbonic acid, which contributes to ocean acidity. It can then be absorbed by rocks through weathering. It also can acidify other surfaces it touches or be washed into the ocean.[6]Human activity over the past two centuries has significantly increased the amount of carbon in the atmosphere, mainly in the form of carbon dioxide, both by modifying ecosystems' ability to extract carbon dioxide from the atmosphere and by emitting it directly, e.g. by burning fossil fuels and manufacturing concrete.[2]

This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans in billions of tons of carbon per year. Yellow numbers are natural fluxes, red are human contributions in billions of tons of carbon per year. White numbers indicate stored carbon.

Carbon dioxide absorbs infrared radiation, thus rising levels of Carbon dioxide in the atmosphere raises concerns of climate change. Greenhouse effectAs thermal radiation reaches the planetary surface, some photons will reflect back into space less the stopped by the greenhouse effect which usually results in an elevation of temperature on the planetary surface. Without greenhouse gases Earth would be -180C iced and inhabitable. Carbons role in the greenhouse effect occurs when carbon-oxygen bonds stretches or flexes at a frequency that allows them to absorb an infrared photon. As Carbon dioxide can vibrate in asymmetrically as well as by flexing, allowing it to absorb at different frequencies of infrared red. Infrared absorption of carbon shows two main peaks. As the IR photons are re emitted in a random direction, approximately half of them are readmitted to the Earths surface.Source of carbon dioxide Combustion of fossil fuels (coal, natural gas, and oil) for energy, or transportation Industrial processesMajor consequences of Carbon DioxideAcceding to the U.S. Global Change Research Program, average temperatures in the US increased increase by 2F to 11.5F by 2100, precipitation by 5%; little wonder that over the last century sea levels increased 7 inches despite having noticeable change within the last 2000 years. For every 1.8F increase in tropical sea surface temperatures the rainfall rates of hurricanes could increase by 6-18%, wind speeds of the strongest hurricanes could increase by about 1-8%. Winter storms are projected to become stronger and more frequent.

The intensity of Atlantic hurricanes is likely to increase as the ocean warms. Climate models project that for each 1.8F increase in tropical sea surface temperatures the rainfall rates of hurricanes could increase by 6-18% and the wind speeds of the strongest hurricanes could increase by about 1-8%. [1] There is less confidence in projections of the frequency of hurricanes, but the global frequency of tropical hurricanes is likely to decrease or remain essentially unchanged. [5]Cold-season storm tracks are expected to continue to shift northward. The strongest cold-season storms are projected to become stronger and more frequent. [1]

Northern countries will suffer plague and disease such as malaria native to warmer climates. Warmer temperatures result in stronger, more frequent storms such as in 2004 and 2005 Areas of Earth such as Africa will suffer severe droughts 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow will cause sea levels to rise 230 feet and rewrite natural occurring water currents and temperatures around the world with them. Greater floods may result in U.S. eastern seaboard and one sixth of Bangladesh permanently lost by a 1.5 m sea rise.
