Our Relation to the Carbon Cycle and Earth’s Energy Budget Almost everything human’s use require a form of energy. Unfortunately‚ fossil fuel is the source of energy we use to sustain ourselves. Fossil fuels emit large quantities of greenhouse gas‚ which increases the amount of carbon in the atmosphere. Our relationship to the carbon cycle and Earth’s energy budget has multiple layers. Almost everything we use requires a form of energy. To power technology‚ we burn fossil fuels. The burning of

Normally‚ people think CO2 is the chief source that affects global warming; however‚ methane is more dangerous than CO2. Among the total emissions in 2013‚ which was 6‚673 million metric tons‚ carbon dioxide took around 82%‚ while methane was 10%. It seems methane doesn’t occupy much of gas emissions. However‚ the potential power of methane weighs than CO2’s. The level of methane in the air has gradually increased by man-made activities. Methane’s live in the atmosphere is 12 years (EPA‚ 2010).

In the atmosphere was where I started. Seventy five years I was there. A carbon atom in a carbon dioxide molecule was what I was. A Pinyon pine tree going through photosynthesis took me from the atmosphere. After I left my home‚ I converted into a tissue in a Pinyon pine needle. This was only the first part of the cycle‚ and I was going to the biosphere-plant. A new territory‚ the biosphere-plant. Accordingly‚ I existed as a tissue in a Pinyon pine needle. For two months I stayed like that.

The Concentration of CO2 in the Atmosphere Introduction Carbon dioxide (CO2) is a colorless‚ odorless‚ non-flammable gas that can be produced by cellular respiration and burning of fossil fuels. Many types of industries such as breweries‚ mining ore and the manufacturing of carbonated drinks‚ drugs‚ disinfectants‚ pottery‚ and baking powder; utilize the CO2 gas (Appendix C). Recently Scientist proposed a theory in which CO2 concentration levels above 450ppm will lead to dramatic and potentially

2013 Carbon Footprint Until very recently‚ most people had never heard of a “carbon footprint.” Now‚ all of a sudden‚ the phrase is hard to avoid. In an age of slick slogans‚ fast fashions and fickle fads it’s easy to assume that this is just another quirky passing gimmick. But it could well be the most important concept of our time. A carbon footprint is the amount of carbon dioxide (CO2) emitted as a direct or indirect result of an activity (Yarrow‚ Joanna. How to Reduce Your Carbon Footprint:

the carbon footprint of plastic grocery bags during its life cycle‚ I should first explain what does the carbon footprint term stand for‚ I would take the definition given in the textbook of this course‚ "The carbon footprint is the total emissions of CO2‚ more specifically greenhouse gases as CO2‚ equivalent (CO2e)‚ that is generated by individual‚ organization‚ event‚ product or process over its life-cycle". Knowing what the carbon footprint means now‚ I know that for discussing the carbon footprint
