BIO 220 global warming essay: a planning guide

Three numbered points and a 500 to 750 word limit gives you roughly 200 words each, with an introduction and conclusion to fit around them. That is tight enough that the essay has to be planned rather than drafted. Point one asks what global warming is, point two asks how human activities affect it, and point three asks what you can do as an individual to minimise your contribution. Note that the three are sequential rather than independent: the mechanism you set out in point one determines which human activities matter in point two, and those activities determine which individual actions are worth taking in point three. An essay written that way holds together. One written as three separate answers reads as three paragraphs that happen to share a topic, and at this length there is no room to repair that in the conclusion.

The definition is where accuracy matters most and where a first-year essay can most easily go wrong. Global warming is the long-term rise in Earth's average surface temperature. The mechanism is that certain gases in the atmosphere, principally carbon dioxide, methane and nitrous oxide, are transparent to incoming shortwave solar radiation but absorb outgoing longwave infrared radiation and re-emit it in all directions, including back toward the surface. That is the greenhouse effect, and it is worth stating clearly that the effect itself is natural and necessary, since without it the planet would be far colder. What is not natural is the increase in the concentration of those gases, and it is the increase, not the effect, that this essay is about. Making that distinction in two sentences will separate your essay immediately from the ones that treat the greenhouse effect itself as the problem, which is both a common error and one an instructor will notice at a glance.

Point two should be structured by the size of the contribution rather than by what comes to mind first. The dominant human activity is burning fossil fuels for energy, transport and industry, which transfers carbon that was locked in geological storage into the atmosphere. Land use change is second, principally deforestation, which both releases stored carbon and removes future uptake. Agriculture contributes methane from livestock and rice cultivation and nitrous oxide from fertiliser, and both of those gases are more potent per molecule than carbon dioxide though present in smaller quantities. Cement production contributes chemically as well as through its energy use. Ordering them by magnitude and saying so is a small thing that reads as competence, and it also gives point three something to work with, since an individual action is worth proposing in proportion to how large the activity it addresses turned out to be.

Point three has a trap in it and it is worth avoiding deliberately. Asked what they can do as individuals, most essays produce a list dominated by low-impact actions: recycling, turning off lights, reusable bags. None of those is wrong, and all of them are small relative to a footprint dominated by heating, driving, flying and diet. Rank your actions by effect rather than by familiarity, and be honest that the largest individual levers are also the ones most constrained by circumstance. It is also legitimate, and more interesting, to note that individual action operates alongside collective and political action rather than instead of it, provided you still answer the question that was asked about your own contribution rather than substituting a paragraph about policy for it. The question is about you, and the honest answer is more interesting than the complete one.

Sourcing matters here because the topic attracts a great deal of unreliable material in both directions. A minimum of two references is required, and the obvious choices are the strongest: national scientific agencies and the intergovernmental assessment reports summarise the evidence and are written to be cited. Avoid news coverage as your primary source, since it reports findings at one remove and often loses the qualifications. Cite the specific claim rather than the site, so a figure for the temperature rise, a figure for the concentration change, or a stated attribution finding, each attached to where it came from. Two well-used sources will outperform five listed, and the minimum of two is genuinely a minimum here rather than a target, because two agency or assessment sources can support every factual claim a 750-word essay on this topic needs to make.

On mechanics, every requirement in this brief is stated explicitly and can be checked in under a minute, which means losing marks on any of them is entirely avoidable. Five hundred to seven hundred and fifty words, a minimum of two references, GCU Style Guide formatting rather than APA, submission to Turnitin, and Word documents only. The brief also says to review the grading rubric before beginning, which is worth doing because with three equally weighted points the marks are probably distributed evenly, and an essay that spends four hundred words on consequences and eighty on the definition has misallocated its effort regardless of how well it is written. Draft each point to two hundred words separately, then write the introduction and conclusion with whatever is left, which is the only reliable way to keep three equal points equal.
