A. The Causes (Nguyên nhân)

The primary driver of modern climate change is human activity, specifically processes that release harmful substances into the atmosphere.

Emission: The production and discharge of gases, notably Carbon Dioxide (CO2). We often talk about reducing carbon emissions.
Fossil fuels: Natural fuels like coal, oil, and natural gas. The continuous burning of these fuels is the main source of the problem.
Deforestation: The large-scale removal of trees. Trees naturally absorb CO2; without them, the greenhouse effect worsens.
The greenhouse effect: The process where gases trap the sun's heat within the Earth's atmosphere, causing global temperatures to rise.
Urbanization: The rapid growth of cities, leading to increased energy consumption and pollution.

B. The Consequences (Hậu quả)

If global warming continues at its current rate, the environmental impacts will be devastating and irreversible.

🧊 Glaciers: Huge masses of ice in the polar regions. They are melting rapidly, which leads to sea-level rise.
🏜️ Drought: A long period with no rain. This severely impacts agriculture and leads to water shortages.
🌊 Extreme weather events: An increase in the frequency of hurricanes, floods, and heatwaves.
🐾 Habitat loss: Animals lose their natural homes, pushing many species to the brink of extinction.

C. Sustainable Solutions (Giải pháp Bền vững)

To combat climate change, a global shift towards sustainability is urgently required.

Renewable energy: We must transition from fossil fuels to sources that won't run out, such as solar power, wind turbines, and hydropower.
Reduce your carbon footprint: Individuals can help by lowering their personal energy use (e.g., taking public transport instead of driving).
Conservation: The careful management and protection of natural environments and wildlife.
International treaties: Governments must sign and strictly enforce agreements (like the Paris Agreement) to limit industrial pollution globally.

Exercise 4.5: IELTS Writing Task 2 Integration

Reading Context

Read the essay introduction and fill in the blanks using words from the theory.

The ongoing crisis of global warming is primarily driven by human activities, such as the rampant burning of (1) fuels and widespread (2) (cutting down trees). These actions release massive quantities of carbon dioxide, exacerbating the (3) effect. Consequently, the planet is experiencing severe ecological changes, including the melting of polar (4) and prolonged periods of (5) (no rain) in agricultural regions. To prevent the inevitable (6) (dying out) of vulnerable species, nations must transition towards sustainable energy sources immediately.
