IELTS Global Warming Essay – Model Answer
Probably the most worrying threat to our planet at the present time is global warming. This essay will examine the reasons why global warming is occurring and discuss some possible solutions.
The predominant factors resulting in the warming of the earth are the emissions of CO2 and deforestation. CO2, which damages the ozone layer, comes from several sources, but the most problematic are those coming from the burning of fossil fuels from power plants. This releases thousands of tonnes of CO2 into the atmosphere every year. Another cause of these emissions is the burning of gasoline for transportation, which continues to grow because of our demand for cars and also our increasing worldwide consumption, resulting in an escalating need to transport goods. Also, forests store large amounts of carbon, so deforestation is causing larger amounts of CO2 to remain in the atmosphere.
Nevertheless, there are potential ways to solve these problems or at least reduce the effects. Firstly, governments need to reduce our dependence on fossil fuels and promote alternatives. Plant-derived plastics, biodiesel, wind power, and solar power are all things that are a step in the right direction, but governments need to enforce limits on CO2 emissions for the polluting industries in their countries for these to be effective. Also, individuals can play a part by making lifestyle changes. People should try to buy cars with the best fuel economy and only use their cars when really necessary. They can also switch to energy companies that use renewable energy rather than fossil fuels. Finally, small things like buying energy-efficient light bulbs, turning off electricity in the house, and planting trees in the garden can help.
To conclude, although global warming is a serious issue, there are steps that governments and individuals can take to reduce its effects. If we are to save our planet, it is important that this is treated as a priority for all concerned.

Evaluation:
Task Achievement: Band 8
The essay effectively addresses the question by discussing the reasons for global warming (CO2 emissions and deforestation) and proposing several solutions. The causes are clearly explained with appropriate examples, such as fossil fuel usage and deforestation’s impact on carbon storage. The solutions, including government intervention and individual actions, are practical and relevant. However, the essay could improve by briefly mentioning the potential challenges of implementing these solutions, such as economic or political obstacles, for a more nuanced analysis.
Coherence and Cohesion: Band 8.5
The essay is well-organized with a clear introduction, body paragraphs that address causes and solutions, and a concise conclusion. Cohesive devices like “nevertheless,” “firstly,” “also,” and “finally” are used effectively to link ideas and maintain logical flow. Paragraphs are coherent, with a clear focus in each, and transitions between ideas are seamless.
Lexical Resource: Band 8.5
The vocabulary is varied and appropriate for the topic. Terms like “deforestation,” “escalating need,” “renewable energy,” “energy-efficient light bulbs,” and “lifestyle changes” demonstrate a good range. Synonyms and paraphrasing are used effectively, and there is no noticeable repetition of phrases. To achieve a higher score, more advanced and specific terms related to environmental science could be incorporated.
Grammatical Range and Accuracy: Band 8
The essay demonstrates a strong command of grammar, using a range of complex and compound sentences. Grammar is largely accurate, though there is a slight overgeneralization in “CO2, which damages the ozone layer” (CO2 primarily contributes to the greenhouse effect, not direct ozone layer damage). Sentence structures are varied and clear, contributing to the overall readability and precision.
Word Count: 338 words
The essay exceeds the required word limit, providing detailed analysis without being overly verbose or irrelevant.
Overall Band: 8.5
This is a high-quality essay with clear reasoning, relevant examples, and practical solutions. To reach Band 9, the essay could incorporate more nuanced analysis of the challenges and consequences of the proposed solutions and demonstrate a slightly broader range of advanced vocabulary specific to environmental issues.
