Writing an Essay on Global Warming
Global warming is no more a theory, it’s happening right now! In plainer terms, a person ignorant of it or denial is also in the easiest terms guilty. One need only look at the weather and climate changes over the last 60 years to see what we can expect in the next half century. Temperatures have risen, glaciers are melting and insects that were restricted to certain areas of the world are spreading into other regions. The good news is that many people are waking up to the alarming trends and are rejecting the view that global warming is a hoax or a myth.
If you are going to write an essay on global warming, you will need to write three pages on the subject, explaining in layman’s terms what the theory is and how it applies to current climate change. Since you won’t be able to include the physical science of greenhouse gases into your discourse, you will need to explain it in simple language. This is not as daunting a task as it may seem.
Start by collecting some data. It doesn’t take much, just a few spreadsheets or open sources such as the internet, the UN and the World Meteorological Organization. You will need to look at temperature, precipitation, cloud cover and land elevation. You will then want to compare these figures to global averages for the period since 1950. This should give you a fairly good idea of what to expect in the next few decades.
After you have your data, the next step is to research the environmental issues involved with global warming. Again, there are plenty of books to choose from that will explain the basics of global warming and the environmental issues involved. One of the better books to read is “In Defense of Earth, A Book About Global Warming and Environmental Issues” by James Turner. It’s a very quick read, so it won’t bog down your reading speed.
Now here comes the fun part. Your essay should answer five key questions. First, are global warming and climate changes real? Second, is there a connection between global warming and climate change? Third, can we predict future climate changes in temperatures and humidity?
Answer the first question first, yes they are real and there is definitely a direct correlation between global warming and climate change. There are several theories on the subject. Some scientists theorize that the poles are getting warmer because of greenhouse gases, others believe a slowdown in global warming is already happening, and there are still others who feel that the earth’s average temperature is constantly changing. The results of all these theories are still inconclusive. Therefore, the debate rages on.
Next, do the climate change and global warming theories explain why some regions are colder than others? It would make sense to include information on why the polar regions are affected, if not why other areas aren’t affected. This can be answered in three ways: clouds, rainfall, and snowfall. If the theory says that clouds affect temperatures, then you should include information about which types of clouds are present and how much cloud cover is present, especially if your topic deals with cloud cycle or climate history.
Last, but certainly not least, do the facts support the claims of your global warming essay? How do experts arrive at the results of climate change and global warming studies? How do researchers test theories and determine if global warming really occurs? These are important topics that require solid research to arrive at correct results, so make sure you include this information with your global warming paper.
