Global warming is when the earthheats up (the temperature rises). Ithappens when greenhouse gases(carbon dioxide, watervapour, nitrous oxide, and methane)trap heat and light from the sun inthe earth’s atmosphere, whichincreases the temperature. Thisaffects all life on earth.(Humans, animals, plant life etc)
The greenhouse effect iswhen the temperaturerises because the sun’sheat and light is trappedin the earth’satmosphere. This is likewhen heat is trapped ina car. On a very hotday, the car gets hotterwhen it is out in theparking lot. This isbecause the heat andlight from the sun canget into the car, by goingthrough thewindows, but it can’t getback out. This is what thegreenhouse effect doesto the earth. The heatand light can getthrough theatmosphere, but it can’tget out. As a result, thetemperature rises.
Global warming is the endresult of man for using upresources. There are manyreasons why globalwarming occurs today. Oneof the major reasons is theconsumption of too muchenergy. When you do notunplug appliances(exampleTV) before going tobed, this eats up moreelectricity, or cars runningon gas or petrol. All ofthese activities requireenergy. To produceenergy, we use up fossilfuels that are dug rightfrom the ground. Fossil fuels are producedfrom decaying plants andanimals. When oil fromfossil fuels is burned, itcreates a dreadful odourthat pollutes the air webreathe. Moreover the endresults of used up fuels canalso pollute our water. Asenergy is used up thechemicals emitted causethe Earth to behavesimilarly to agreenhouse, thus the termgreenhouse gases.
In globalwarming, excessive heat istrapped here onEarth, damaging crops andtrees, and habitats ofanimals as well. A rise inthe temperature in theocean waters affect eventhe glaciers, and oncethese melt completely notonly will the animalsresiding there lose theirhome, the melted ice capscan cover nearly more thanhalf of the Earth’s terrainand population. Polar caps are now said tobe thawing more than fivetimes faster than before.
The consistent burningup of fossil fuels willbring environmentaldisasters and calamityto us all. Today mostpeople do not caremuch about theenvironment, andcontinue to use upenergy without anyregard for theirsurroundings. Weexperience heat waveseven during the coolmonths. Droughts have beenreported, and arewidespread. Climatechange causeshurricanes, leavingtens of thousands ofpeoplehomeless, missing ordead. Global warmingwill cause morenatural disasters.Example: Tsunami
