Essay On Global Warming In 600 Words Answers

IELTS Global Warming Essay

This model answer is for an IELTS global warming essay.

You are asked in the question to discuss the causes of global warming and possible solutions for individuals and the government.

Here is the question:

Global warming is one of the most serious issues that the world is facing today.

What are the causes of global warming and what measures can governments and individuals take to tackle the issue?

So you must answer these three things in order to fully answer it:

  1. What are the causes of global warming?
  2. What can governments do about it?
  3. What can individuals do about it?

This essay has been divided into two paragraphs.

However, you could write a separate paragraph about each of the above points if you wanted.

Take a look at the model answer and examine how it has been organized.

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 the 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 car 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.

Increasing ocean acidification

Although it has gained less mainstream media attention, the effects of increasing greenhouse emissions — in particular carbon dioxide — on the oceans may well be significant.

Scientists have found that oceans are able to absorb some of the excess CO2 released by human activity. This has helped keep the planet cooler than it otherwise could have been had these gases remained in the atmosphere.

However, the additional excess CO2 being absorbed is also resulting in the acidification of the oceans: When CO2 reacts with water it produces a weak acid called carbonic acid, changing the sea water chemistry. As the Global Biodiversity Outlook report explains, the water is some 30% more acidic than pre-industrial times, depleting carbonate ions — the building blocks for many marine organisms.

In addition, (See p. 58 of the report.)

Although millions of years ago CO2 levels were higher, today’s change is occurring rapidly, giving many marine organisms too little time to adapt. Some marine creatures are growing thinner shells or skeletons, for example. Some of these creatures play a crucial role in the food chain, and in ecosystem biodiversity.

Some species may benefit from the extra carbon dioxide, and a few years ago scientists and organizations, such as the European Project on OCean Acidification, formed to try to understand and assess the impacts further.

One example of recent findings is a tiny sand grain-sized plankton responsible for the sequestration of 25–50% of the carbon the oceans absorb is affected by increasing ocean acidification. This tiny plankton plays a major role in keeping atmospheric carbon dioxide (CO2) concentrations at much lower levels than they would be otherwise so large effects on them could be quite serious.

Other related problems reported by the Inter Press Service include more oceanic dead zones (areas where there is too little oxygen in the sea to support life) and the decline of important coastal plants and forests, such as mangrove forests that play an important role in carbon absorption. This is on top of the already declining ocean biodiversity that has been happening for a few decades, now.
