Topic: Climate change

Level: B1/B2

Time: 90 mins

Aims:

  1. to help students develop their understanding of what climate change is

  2. to introduce and practise some vocabulary of climate change

  3. to ask and answer questions to find out about climate change

  4. to develop note-taking skills

Introduction In this lesson students will gain an overview of what climate change is. They will read some short texts, exchange information and make notes. They will also learn some useful vocabulary on the topic.

Materials: Cut-up information cards, 3 x worksheets

Procedure:

1. Warmer: put on the board: ‘What are the most important issues facing your country or town at present?’ Give students a couple of minutes to discuss in pairs, and then feedback as a class.

2. Give out Worksheet 1 ‘Taking notes’. Students choose which notes are better and why. (Possible answer: the second set because they don’t just repeat sentences from the text, they use bullet points, shorthand and their own words).

3. Give out Worksheet 3 - ‘Mingle Worksheet’ - and tell learners they are going to make notes under the appropriate heading. They can make notes in answer to the first question using the text from ‘Taking Notes’ worksheet.

4. Now give out the seven cut-up short texts on climate change (Worksheet 2), one to each student (if you have a bigger group you can either put students in pairs with one text, or allow more than one student to have the same text).

5. Learners go and speak to someone else and find out what the other person learned. They can refer to the short texts the first time. When they go on to speak to the next person they should give the texts to the teacher, and tell the next person the information from memory. They finish when they have got notes next to all the questions.

6. Language focus: climate change lexis. Learners match the vocabulary from the text to the definitions.

Worksheet 1: Taking notes

What is climate change?

To understand climate change, it’s important to recognise the difference between weather and climate. Weather is the temperature, precipitation (rain, hail, sleet and snow) and wind, which change hour by hour and day by day. Climate is the average weather and the nature of its variations that we experience over time.

The greenhouse effect is the natural process of the atmosphere letting in some of the energy we receive from the Sun (ultraviolet and visible light) and stopping it being transmitted back out into space (infrared radiation or heat). This makes the Earth warm enough for life.

For several thousands of years the atmosphere has been delicately balanced, with levels of greenhouse gases relatively stable. Human influence has now upset that balance and, as a result, we are seeing climate change.

Look at the notes two people took about the article. Which do you think are better and why? Example 1 or example 2? Discuss with your partner. Example 1

For several thousands of years the atmosphere has been delicately balanced, with levels of greenhouse gases relatively stable.

Example 2

  1. weather/climate different – short term vs. long term

  2. Greenhouse effect – natural process, keeps earth warm enough!

  3. people upsetting balance – climate change

Worksheet 2: Cut out the following boxes and distribute one for each student.

How are we causing climate change?

Human activities, like travelling by car, eating hamburgers or heating water in the home have led to an increase in greenhouse gases in the atmosphere, causing an enhanced greenhouse effect and extra warming.

As a result, over the past century there has been an underlying increase in average temperatures which is continuing. Globally, the ten hottest years on record have all been since 1997.

But isn’t the climate always changing?

Yes. There is natural variability in Earth’s climate but the current climate change is very unusual as it is not exclusively part of a natural cycle.

Natural factors include volcanic eruptions, aerosols and phenomena such as El Niño and La Niña (which cause warming and cooling of the Pacific Ocean surface). Natural climate variations can lead to periods with little or no warming, both globally and regionally, and other periods with very rapid warming. However, there is an underlying trend of warming that is almost certainly caused by man’s activities.

Do climate scientists really agree about climate change?

Yes. The overwhelming majority of climate scientists agree on the fundamentals of climate change — that climate change is happening and has recently been caused by increased greenhouse gases from human activities.

The core climate science from the Intergovernmental Panel on Climate Change (IPCC) was written by 152 scientists from more than 30 countries and reviewed by more than 600 experts. It concluded that most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in man-made greenhouse gas concentrations.

Are you sure there’s a link between temperature rise and CO2?

Yes. Temperature and CO2 are linked. Studies of polar-ice layers show that in the past, rises in temperature have been followed by an increase in CO2. Now, it is a rise in CO2 that is causing the temperature to rise.

Concentrations of CO2 have increased by more than 35% since industrialisation began, and they are now at their highest for at least 800,000 years.

When natural factors alone are considered, computer models do not reproduce the climate warming we have observed. Only when man-made greenhouse gases are included do they accurately recreate what has happened in the real world.

Has global warming stopped?

No. The rise in global surface temperature has averaged more than 0.15 °C per decade since the mid-1970s. The 10 warmest years on record have occurred since 1997. Global warming does not mean that each year will necessarily be warmer than the last because of natural variability, but the long-term trend is for rising temperatures. The warmth of the last half century is unprecedented in, at least, the previous 1,300 years.

How can I help?

Over 40% of current CO2 emissions are caused by the choices we make as individuals. Simple actions can save money and energy; and there are many things you can do to reduce your CO2 emissions, from switching off electrical appliances when they are not being used to insulating your home properly and walking instead of driving one short trip a week, taking the train instead of flying or putting in energy-saving light bulbs in your home.
