What is the international community doing?
Sea levels have risen by 10 – 20 cm. This is due to the expansion of warming oceans. Temperature records show that the average temperature has increased by about 0.6ºC in the 20th century.
The Kyoto Protocol (1997) commits industrialised countries to reduce their greenhouse gas emissions. It suffered a huge set back in 2001 when the USA, responsible for a quarter of global emissions, pulled out.
The planet’s climate is constantly changing but now scientists believe that the extreme changes taking place today are a result of human activity. The changes we see today may affect the stability of the climate on which much life on the planet depends.
The term refers to the role played by the layer of gases, including carbon dioxide, methane and nitrous oxide, which trap the heat from the sun in the earth’s atmosphere. We need the layer to keep in some of the heat but now the concentration of gases, especially CO2 is increasing and retaining more heat.
It is difficult to predict, but we can expect more extreme weather conditions like floods, storms and heat waves. Scientists believe there will be more rain but also a higher risk of drought in inland areas

Global warming message board
The idea for this activity was from a real message board on a website about the weather. Most of the views are adaptations of what real people think. This activity offers the students a look at the other side of the coin; some of the potential advantages of global warming! It should be used to provoke students’ own ideas and thoughts on the subject and may trigger some strong reactions.
Give each student a copy of Worksheet D.
Worksheet D – Global warming message board
A message board on a weather website asked its readers to write in with their views on global warming and climate change. Here is a selection of their messages.
Gonzalo – I’m all in favour of global warming. I grow tropical plants so for me the warmer the weather is the better!
Tanya – In 20 years time the traditional British weather will be a thing of the past. We’ll have a climate like the south of France. People will be healthier as they’ll spend more time outdoors. Just think, dining al fresco in the summer months. It’ll be great!
Luis – no one can tell me that global warming isn’t happening. We’ve just had the hottest year on record! My sister lives in the north of Spain and she said that it is beach weather there and it’s November. I mean it’s not normal is it?
Kevin – When I was a boy we used to have heavy snow most years. Since the early 90s all we’ve had is a light dusting of snow. It must be due to global warming.
Ruth – You only have to switch on the news to see the crazy things the weather is doing. There are so many floods, hurricanes and droughts. It’s the extreme weather conditions caused by global warming.
Oliver – There’s no such thing as global warming. It’s all media hype to brainwash people. If they told us the moon was made of cheese often enough people would believe it!
Mark – The world will never be the same again, but that’s how it has always been. It changes constantly and nature and man can adapt to these changes. If we couldn’t, human life on the planet would have finished years ago.
Who do you agree with most?
