Its relevance to global environmental concerns and its impact on human populations make it a recurring theme. Based on past trends, we can expect similar questions to appear in future IELTS exams.
Let’s examine a typical IELTS Writing Task 2 question on this topic:
Rising sea levels are threatening coastal communities around the world. What are the causes of this problem, and what measures can be taken to address it?
Deconstructing the Question
This question has two main parts:
- Identify the causes of rising sea levels
- Propose measures to address the problem
To score well, you need to address both parts comprehensively while maintaining a clear structure and using appropriate language.

Band 8-9 Essay
The encroachment of oceans on coastal areas is a pressing global concern with far-reaching consequences. This essay will explore the primary factors contributing to rising sea levels and suggest potential solutions to mitigate this environmental crisis.
The main culprit behind rising sea levels is undoubtedly climate change. As global temperatures increase, two major processes occur: thermal expansion of the oceans and the melting of land-based ice. Thermal expansion happens when water molecules absorb heat and occupy more space, causing sea levels to rise. Simultaneously, the melting of glaciers and ice sheets in polar regions adds significant volumes of water to the oceans. Human activities, particularly the burning of fossil fuels and deforestation, exacerbate these processes by releasing greenhouse gases into the atmosphere, trapping heat and accelerating global warming.
To address this complex issue, a multi-faceted approach is necessary. First and foremost, reducing greenhouse gas emissions is crucial. This can be achieved through a transition to renewable energy sources, improving energy efficiency in buildings and transportation, and implementing carbon pricing mechanisms. Additionally, protecting and restoring natural carbon sinks such as forests and wetlands can help absorb excess carbon dioxide from the atmosphere.
Adaptation measures are equally important for coastal communities already facing the impacts of rising seas. These may include constructing sea walls and flood barriers, elevating buildings and infrastructure, and implementing early warning systems for storm surges and flooding events. Furthermore, managed retreat – the planned relocation of communities from high-risk areas – should be considered as a long-term strategy for the most vulnerable locations.
International cooperation is essential in tackling this global challenge. Developed nations should provide financial and technological support to developing countries, which are often disproportionately affected by rising sea levels but lack the resources to implement effective solutions.
In conclusion, addressing the threat of rising sea levels requires a combination of mitigation strategies to reduce greenhouse gas emissions and adaptation measures to protect coastal communities. Only through concerted global efforts can we hope to safeguard our coastlines and the millions of people who call them home.

Band 6-7 Essay
Rising sea levels are a big problem for many coastal areas around the world. This essay will discuss the reasons for this issue and some ways to deal with it.
The main cause of rising sea levels is global warming. As the Earth gets hotter, two things happen: the water in the oceans expands, and ice in cold places like Antarctica melts. Both of these make the sea level go up. Human activities like burning fossil fuels and cutting down forests are making global warming worse because they release gases that trap heat in the atmosphere.
To solve this problem, we need to do several things. First, we should try to reduce the amount of greenhouse gases we produce. This can be done by using more renewable energy like solar and wind power, and by making cars and buildings more energy-efficient. We should also plant more trees to help absorb carbon dioxide from the air.
For places that are already affected by rising seas, we need to take action to protect them. This could include building sea walls to keep the water out, or raising houses and roads so they don’t flood. In some cases, people might need to move away from areas that are at high risk of flooding.
It’s also important for countries to work together on this problem. Rich countries should help poorer ones that are affected by rising seas but don’t have enough money to protect themselves.
In conclusion, rising sea levels are caused mainly by global warming, and we can address this problem by reducing greenhouse gas emissions and helping coastal communities adapt to the changes. It will take a lot of effort from everyone to solve this issue.
