The average temperatureon Earth is usually 61 degrees Fahrenheit or 16 degrees Celsius. Global warminghas been described as a complex, scientific “term” to portray a gradualincrease in the average temperature of the Earth’s atmosphere which alsoincludes its oceans. The gradual increase of temperature appears to be causedby the increased levels of gases such as carbon dioxide, chlorofluorocarbons,and many other pollutants mostly contributed by human emissions causing severedamages into atmosphere.
Many people including scientist believe that GlobalWarming is leading to the permanent change of the Earth’s climate and possibly projectedto continue on forever. However, when scientists use the term, Global warming,they often are concerned about human activities or human emissions that arecausing the issue of climate change. Many people of course do not understandthe real science including the cause and effect of this phenomenon. As a resultof the creation of gases which trap energy mostly through human activity, thisis causing a gradual rise in the atmospheric temperatures (global warming).
(Miller, RoxanneGreitz. “Inside Global Warming.”)Accordingto our textbook, (Chemistry in Context- ApplyingChemistry to Society- Chap 3), Global warming seems to be a result of thegreenhouse affect due to its gradual temperature increase, worldwide. Thegreenhouse effect is described as, “the process by which the Earth keeps aconstant temperature by having an atmosphere containing water and carbondioxide.” (Chapter 3 & 4) Heat radiation is able to go through theatmosphere by gases (carbon dioxide and methane for example) however it alsoprevents radiation “reflected off the surface of the earth from exiting theatmosphere.
” In sum, this is how the heat is kept enclosed. Human activity suchas burning fossil fuels (amongst other human emissions) causes a great increasein the carbon dioxide concentration in our atmosphere which is boosting thegreenhouse effect because global temperatures are becoming extremely high. There has been strong evidential proof that humanemissions is causing our Earth to increase in temperature a bit faster thanusual which will result in an unpleasant effect on weather, plant life, oceanlevel, wildlife/aquatic-marine animal life, and life on Earth overall due toGlobal warming. According to, (SCHNEIDER, STEPHENH.
et al. Global Warming.; Issues in Science and Technology), burningfossil fuels are one of the biggest causes in global warming and when fossil fuelsare burned, they tend to give off gases one of which, CO2 because fossil fuelsare made up or organic matter; for example coal or oil.
In addition, whenfossil fuels are dug up from the ground, methane is being released also butmethane is naturally in the ground, hence, mining coal as well as oil allowsthe methane to escape into atmosphere which is a pollutant. Now, as humanbeings, we need food to eat for energy. Our Earth is populated with billions ofpeople, hence, the more babies that are being born, for example, more food isneeded to feed human beings.
With more food, comes more breeding/raising ofanimals and agriculture which mean there would be more fossil fuels burning(methane is released into the atmosphere). We use cows, for example for milkand beef (meat). When animals like cows release manure which is considered tobe “an organic matter” or feces it also consist of methane. Green manurehowever is used as organic fertilizer in our agriculture. (SCHNEIDER, STEPHEN H., et al.
“GlobalWarming.” Issues in Science and Technology) With that being said,we studied in chapters 1 through 4 in our textbook that transportation isanother big issue that contributes to global warming and pollution. The animalsthat are being raised and the agriculture that is being grown to feed us has tobe delivered or transported so that we can buy the produce which means morepollutants in our atmosphere such as nitrogen oxides, carbon monoxide and otherpollutant gases due to motor vehicles.
According to the union of concernedscientists, “in 2013, transportation contributed more than half of the carbonmonoxide and nitrogen oxides, as well as almost a quarter of hydrocarbonsemitted into our air”. Global warming is obviouslythat is occurring in nature whether it is influenced by human emissions or not.Our world is always changing. For some people, Global warming could beconsidered as a pro rather than a con. For example, some people hate the coldweathers and the cause of global warming could possibly introduce longer,warmer weathers which can also result in possibly vanishing winter weatheroverall. With warmer weather, more rainy weather and more CO2 in our air, theremight be a chance for an increasing in agricultural productivity.
This meansthat there could possibly be longer growing seasons for plant life. Forests arebeing killed, for example, so that people can use wood for their chimneys/fireplaces to heat up their homes or used for stove furnaces. If the temperature becausewarmer, there would be less deforestation because there wouldn’t be as much ofa need to use wood to heat up their homes.
(Bryson,Reid A. “GLOBAL WARMING?” Energy & Environment)On the other hand, since CO2 is considered to be one of the biggest sources inthe process of photosynthesis as well as the majority of life on Earth sinceplants are known to be the primary producers in our ecosystem. Therefore, ifthere isn’t enough CO2 or carbon dioxide, this can possibly lead to majordepletion of life on Earth.
As we studied in our textbook (Chemistryin context: applying chemistry to society), we know that Sunlight is very muchvalued because the sun light (energy) shines on our Earth, some of that heat isabsorbed which is then used to heat our ocean water and the heat that is”trapped” by CO2 is used to warm our atmosphere overall. This is how carbondioxide gas might be viewed as a pro instead of a con when it pertains to itsusage. Althoughthere are many pros and cons (more cons than pros in my opinion) to GlobalWarming, there are several steps that we can take in efforts to reduce itsimpact. As I mentioned in this essay, many human being use motor vehicles astransportation which consumes a lot of gas/fuel and also gives off a lot ofcarbon dioxide into our atmosphere.
It would be feasible for our environment itwe used a bicycle during warmer weathers, take public transportation such astrains, or if cars are a must then carpooling should be considered as an optionas well. This would help reduce the amount of pollutants in our atmosphere. Ilearned from Con Edison, that although our televisions, for example, may beturned off; it still uses energy if it is plugged into the socket. So when weare not using electronic devices , we should ensure that it is not plugged intothe wall socket or possibly considered strip outlets when electronic can be on”standby” but we can switch the power switch to “off” so that energy is notbeing used uselessly. The brand of light bulbs that we use in our household isconsidered a big deal believe it or not. For example, if we are usingincandescent bulbs we should definitely replace them with energy efficientcompact fluorescent light bulbs (although they cost just a bit more but it is awell worth investment) which are very easy to find at our local home depotstore or hardware store. For coffee lovers like me, we can visit organic coffeecafes or purchase our coffees at whole foods and places that carry/sell”shade-grown” coffee as opposed to “sun-grown” coffee. Sun-grown coffee isknown to “be produced in areas of devastated rainforest while shade-growncoffee help preserve the rain forest.
” This would help reduce the need forpesticides which would benefit of our planet. I also love to travel, so fortravelers like me, we can spend a little more time researching resorts orhotels that are considered “green” where they save on energy as well as waterin efforts to reduce the use of solid waste. Again, I love meat; I am a meateater but as I mentioned we use cows for beef and cows release manure (feces)which methane is a huge source of. We can therefore reduce our intake of meatas well as dairy and eat more vegetables. When we go grocery shopping even, wecan bring in reusable bags instead of plastic bags which are bad for theenvironment. We can recycle and reuse things in our household such as clothes,electronics, glass/plastic bottles, and etc to eliminate pollutants into ourenvironment.Antarcticais considered to be an “ice continent” located in the northern peninsula of ourEarth, however, recent studies has shown evidence of climate change in one ofthe most coldest parts of our planet (Antarctica). Researches in Antarcticahave discovered, “rapidly growing banks of mosses” on Antarctica’s icypeninsula.
Although people may believe how icy Antarctica is, most parts of itare now showing greenery and appear to be getting even greener as timeprogresses. In fact, “the surface mosses build up a thin layer in the summer, andthen freeze over in the winter. As the layers builds on top of layer, oldermosses subside below the frozen ground where they are well preserved due to thetemperatures.” (Mooney, Chris. “Energy and Environment.”) This is of course abit strange since Antarctica is known for its continent to be covered in icesurrounded by ocean and therefore uninhabited.
There also seems to be more icein the ocean around Antarctica because ice glaciers are breaking off as well asthe ice shelves on the continent. Researchers say that the Arctic’s temperaturehas risen at “almost twice the rate as temperatures in the rest of the world overthe past few decades”. As a result of the sea ice depleting or melting, the Arcticcould possibly take up carbon dioxide due to the increase of tree life which willthen mean more absorption of sunlight which will then cause the land to appear lessreflective and darker. According to NASA’s Goddard institute of Space Studies, “muchof Antarctica has cooled during the past 30 years which resulted from ozone depletionand other factors.” As a result the surface waters surrounding Antarctica have nowwarmed became less saline and also has increased in precipitation. The loss of iceshelves, due to global warming, has impacted the sea level and global climate. Theincreased precipitation will cause the Antarctic ice sheet to thicken as a result. Works Cited Page1.
