Grammar check my global warming essay Please!?
My essay is due tomorrow. The teacher says my argument and material is great, but because my grammar and sentence structure is so poor, I will not recieve a grade untill it is fixed. Please help. Thank you.
While waiting in line at the local grocery store, I notice the clerk never asks “paper or plastic” anymore. Of course not, its all about plastic these days. Save the trees right? In the front of the check stand I notice cloth bags for sale that read “Eco-Friendly, Support Your World”. Above the candy bars are last minute items like high priced light bulbs. The labels read “Save your energy for a brighter future”. Reducing your Carbon Foot Print, it’s the new trend. Why? Because most of us agree we have a pollution problem. More importantly, a global warming problem. At least once a day I am reminded of this controversial environmental issue. Global warming is a controversial issue because there is debate on what the true cause is. Is the earth solely going through its natural process of heating and cooling? Or are we contributing to the natural climate change process with our daily pollutants and inducing the rising temperatures?
Before examining the facts and deciding what the sole cause of global warming is, it is important to know how the whole process works. The earth goes through stages of heating and cooling every 100,000 years or so. The heating stage is caused by “The Green House Effect”. The idea is that the sun’s light sends down solar radiation which heats the earth’s surface. Some of this energy returns to the atmosphere as infrared radiation “aka heat“, and some of this heat is trapped near the surface by Carbon Dioxide (CO2) and other gases (Lewis et al. 918). For the most part this is a good thing. Greenhouse gases create a warm blanket around the earth and keep us warm and alive. Without this blanket of CO2 and other gasses, earth’s temperatures would be much lower. “Oceans would be frozen to the bottom, and life as we know it would be impossible” (Ehrlich 127). This “Green House Effect” is how earth naturally heats itself.
Ronald Bailey, Author of Global Warming And Other Eco-Myths, goes into detail to describe why global warming is not human induced and most likely due to earth‘s natural heating process. He gives a “list” of Eco-Myths that he believes have been “debunked”. According to his book, there is no looming climate disaster. He agrees that we have caused an increase in Carbon Dioxide and other greenhouse gases, but states that this will likely cause a very slow rise in global temperatures with which we can easily cope (2). Like Bailey there are a few others that still deny the human induced theory. They say that global warming is not a major environmental problem nor an environmental crisis and even think that the earth’s atmosphere has actually been in a state of “cooling” (Ehrlich 140). Anti-global warming spokesman Fred Singer argues in an interview by Stephen Goode that global warming just is not happening in any significant way and if it were, it would be good for us (Easton 150).
However, the majority of scientists have a different take on the issue. In the last 150 years, due to burning of fossil fuels, Industrial processes, farming and deforestation, we have added to greenhouse gasses by releasing 280 billion tones of carbon into the atmosphere, with nearly half of it occurring in the last 25 years of the 20th century (Nielsen 86). This is more than double the earths natural output. According to Nasa’s website, In the last 650,000 years CO2 levels in the atmosphere have never risen past 300 parts per million. In 1950 we broke that record and the levels have not dropped since. Today CO2 levels are higher than they have ever been. Increasing at an alarming rate, today we are at 387 parts per million (U.S. Nasa). When we add more CO2 than is removed, we are causing a build up and therefore the temperatures rise.
Scientists started tracking global temperatures in 1898. Coincidentally, average global temperatures have increased since the 1900’s, and even more drastically since 1980 (Lewis et al. 919). In the past century scientists claim the earth’s surface, which is different then our daily temperatures, has warmed by only one degree. By 2050 average global temperatures are projected to rise another 2.5 degrees Fahrenheit. This does not sound like a significant difference, until you consider that the earth’s surface during the last ice age was only seven degrees lower than today’s (Ballantine and Roberts 487). Small variations can make a huge difference, and we do not know what all of those consequences might be if the earth’s surface increases by another two or three degrees. We do know that changes in temperature can alter populations, killing some organisms outright, stressing others and cause migrations (Life 917). According to the U.S. Department of Commerce, the National Climate Data Center states that in the last 15 years we have had 10 of the
so your first paragraph is a very creative way to open but there are a few sentences that are a bit akward. especially this part:
"At least once a day I am reminded of this controversial environmental issue. Global warming is a controversial issue because there is debate on what the true cause is."
and this part:
"We do know that changes in temperature can alter populations, killing some organisms outright, stressing others and cause migrations "
is that straight out of a book? because if it is you should quote it and if its not then you should change it to sound a bit more balanced. =]
