Carbon Dioxide, Main Culprit Of Global Warming After Methane – OpEd


Is CO2 is main culprit of global warming or not? Recently this is very debatable topic, one group says CO2 is a normal gas like hydrogen, nitrogen and oxygen and not a reason of recent global warming but there is group of believers that admit CO2 as culpable and I am believer of second group.

To satisfy them I have a small logical reason as in our surrounding we have a large number of nutrients but not all of equal importance, few are micro and other are macro similarly their ratio in our diet matters a lot. If one exceed its normal limit cause in ill factor of body functioning. Similarly CO2 is main culprit for causing global warming due to presence of carbon which is main building block of nature and nature believes on balance of every thing.

Carbon dioxide (CO2) is a slightly toxic, odorless, colorless gas with a slightly pungent, acid taste. it is currently occurring at an average concentration of about 390 parts per million by volume or 591 parts per million by mass. CO2 gas is 1.5 times as heavy as air, thus if released to the air it will concentrate at low elevations. Warmer air temperatures would result in increased surface-water temperatures, decreased duration of ice cover and, in some cases, lower water levels. These changes may contribute to decreased concentrations of dissolved oxygen.

About three-quarters of the anthropogenic emissions of carbon dioxide to the atmosphere during the past 20 years have been due to fossil-fuel burning. Activities consuming fossil fuels include power generation, transport, industrial/manufacturing processes. The rest of carbon dioxide emissions are predominantly due to land-use change, especially deforestation. The primary reason identified by climate scientists is because of the excess CO2 2 emitted by the human consumption of fossil fuel. humans have increased the content of this carbon dioxide gas in our atmosphere some 30% since the beginning of the industrial revolution. Large quantities of CO2 are produced by lime kilns, which burn limestone (primarily calcium carbonate) to produce calcium oxide ( lime, used to make cement); and in the production of magnesium from dolomite (calcium magnesium carbonate). Other industrial activities which produce large amounts of carbon dioxide are ammonia production and hydrogen production from natural gas or other hydrocarbon raw materials.

Global warming is also by the result of an excess of greenhouse gases, by destroying tropical rainforest’s, which threatens to change climate in an unprecedented manner.. Heat from the sun, reflected back from the earth, is trapped in this thickening layer of gases and global temperatures rise as a result. Carbon dioxide is constantly being exchanged among the atmosphere, ocean, and land surface as it is both produced and absorbed by many microorganisms, plants, and animals. However, emissions and removal of CO2 by these natural processes tend to balance. Since the Industrial Revolution began around 1750, human activities have contributed substantially to climate change by adding CO2 and other heat-trapping gases to the atmosphere.

Trees have a big role to play in life on earth and are basically the only reason we’re alive right now. Its very common that trees absorb carbon dioxide from the atmosphere, convert it into carbon and oxygen which is stored as carbohydrates and sugar, and release oxygen back into the atmosphere, so they acts as lungs of earth and purify the atmosphere from toxic corresponding gas, that is main culprit for global warming.

Air combination also disturbed by theses climatic chain pummels chain reaction In addition, the ratio of oxygen to nitrogen in the atmosphere has declined as CO2 has increased; this is as expected because oxygen is depleted when fossil fuels are burned. The Southern Ocean is the largest of these ocean carbon sinks, soaking up about 40 percent of mankind’s CO2 absorbed by the seas.

According to an estimation future CO2 ranges will presumably continue to rise at a rate of about 2 ppm per year in the near term.

Global temperature is increasing rapidly day by day is a normal scenario in current situations, unfortunately alone we can do nothing , but by a team we can do much more and save our mother (earth) by curing its lungs and that is possible by increasing number of trees .

    I don’t believe it is the CO2, but the heat of combustion from the fossil fuels (as well as the heat from nuclear power).Calculations show that the heat emitted presently is enough to raise the atmospheric temperature by 0.17*F, but actual rise is about one fourth that due to cooling by glacial melting and photosynthesis. I can’t get anyone to buy this, but there are no correlations of temperature and CO2 for which CO2 can be shown to be the CAUSE of the rise in temperature.
