Topics for English Language Learners – Climate Change
Climate change refers to long-term changes in temperatures and weather patterns across the world. In recent decades, scientists have found strong evidence of global warming, mainly caused by human activities such as burning fossil fuels, deforestation, and industrial pollution. These activities increase greenhouse gas emissions, which trap heat in the atmosphere and lead to serious environmental problems.
For ESL and EFL students, climate change is an important global topic that combines language learning, science, and real-world issues. It offers rich opportunities to practice reading, listening, vocabulary, and discussion skills while developing environmental awareness.
Why Learn About Climate Change in ESL Classes?

Climate change is a meaningful topic that encourages critical thinking, global citizenship, and meaningful communication. It helps students learn English while engaging with one of the most important challenges of our time.
Climate Change for ESL Learners
1. Climate Change for ESL Learners in Simple Terms
In simple terms, climate change refers to the gradual increase in the Earth’s temperature over time. This warming causes extreme weather events such as floods, droughts, heatwaves, melting ice, and rising sea levels. These changes affect people, animals, food supplies, and ecosystems all around the world.

2. Main Climate Change Vocabulary
Understanding key climate vocabulary enables learners to discuss environmental issues clearly and confidently.
- Climate change – long-term changes in the Earth’s climate
Climate change affects weather patterns worldwide. - Global warming – the gradual increase in the Earth’s temperature
Global warming is caused mainly by human activity. - Greenhouse gases – gases that trap heat in the atmosphere (e.g. CO₂)
Cars and factories produce greenhouse gases. - Carbon dioxide (CO₂) – a major gas contributing to global warming
Too much carbon dioxide harms the environment. - Fossil fuels – coal, oil, and gas used for energy
Burning fossil fuels increases pollution. - Renewable energy – energy from natural sources like wind and sun
Renewable energy is cleaner and more sustainable. - Pollution – harmful substances released into the environment
Air pollution causes serious health problems. - Deforestation – cutting down large areas of forest
Deforestation reduces the number of trees that absorb CO₂. - Natural disaster – extreme natural events (floods, droughts, storms)
Climate change increases natural disasters. - Sustainability – using resources responsibly for the future
Sustainability helps protect the planet.
💡 Teaching Tip (ESL)
Ask students to match words with causes or solutions, or use them in sentences with should / must / can (e.g. We should reduce pollution).
