Please help to review my task 2 ielts writing: global warming

Pls review my writing, thanks so much!

Task 2: Global warming is the biggest threat people are facing in the 21st century and sea level rises at an alarming rate. What are the causes and what can be done to solve the problems?

More and more global issues related to higher temperature and ocean level rising are the largest threat that human beings face in the current time. The primary cause of this phenomenon is greenhouse gases emission and the most viable solution is renewable resources.

Greenhouse gases, especially carbon dioxide, contribute to warming up the Earth’s atmosphere. Most gases released from human activities as burning fossil fuels like coal, oil for plants, transportation have trap heat in the atmosphere or Greenhouse effect. The hotter atmosphere, the more water heats up, leading to expansion of ocean size and the glacier ice sheets melting in the mountains, Greenland and Antarctic. This result in rising ocean level and the coastal areas would be the first place obviously affected by this increasing elevation of sea surface, in terms of erosion, salted contamination, flooding. Consequently, large impacts on damaging the crops, infrastructure, human’s properties and dangerously threatening to human lives. According to a prediction that two-third coastal cities in the world would disappear in 2050 because of rising sea level.

A long term solution to this predicament is to change and consume renewable energy from clean and friendly resources such as solar, wind, hydropower, geothermal power. While using this energy, not only it doesn’t emit carbon dioxide and other greenhouse gases that take part in planet-warming effects, but also reduce using fossil fuel, which is a limited resource. For instance, Iceland is known for being the most clean electricity country, with 100% of its energy generated from renewable sources (geothermal and hydroelectric power plants). This has encouraged many other parts of the world to switch to green power.

By and large, admittedly, the planet is warmer and sea level surface is higher at severe dangers because human activities have spread out the greenhouse gases. Therefore, people have to take action to use green energy as soon as possible to save this planet.
