3 Experts in climatology and other scientists are extremely concerned about the changes to our climate. Admittedly, climate changes have occurred on our planet before. For example: there had been several ice ages or glacial periods. These changes were different from the modern ones because they occurred gradually and naturally. The current changes aren t the result of natural causes, but of human activity. Furthermore, the changes are occurring alarmingly rapid. The major problem is perhaps, that the planet is warming up. According to some experts, this warming, known as global warming, has been occurring in the last 10,000 years. The implications for the planet are very serious. Rising global temperatures could give rise to such ecological disasters such as floods and droughts. This could have a harmful effect on agriculture. This unusual warming of the earth has been caused partly by so- called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases, not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of sun is trapped. This leads to the warming up of the planet. Politicians are also concerned about climate change and there are now regular meetings on the subject, attended by representatives from many of the world s industrialized countries. In Kyoto, Japan in 1997, it was agreed that the most industrialized countries would try to reduce the volume of greenhouse gas emissions and were given targets for their reductions. It was also suggested that more forests should be planted to create so- called sinks to absorb greenhouse gases. At least part of the problem of rapid climate change has been caused by too drastic deforestation. Sadly the targets are not being met. Even more sadly, global warnings about climate changes are often still being regarded as scaremongering. Answer these questions 1. What climate changes have taken place before the present time? 2. What are the main differences between modern climate changes and the ones that occurred in the past? 3. What were the agreements reached in the summit in Tokyo? 4. Which suggestions were made and why? Express your opinion: Is global warming true or false? Give reasons....

5 Name: Class Date Light from the Sun 1. What type of radiation does the sun emit? What gases in the atmosphere i. ii. iii. iv. stop the heat from escaping? The Greenhouse effect This is because these gases (absorb/reflect/transmit) the heat energy? Which gas has increased due to humans? 2. The radiation passes through the Earth s and hits the Earth s surface. 3. When radiation passes through something this means that it is Greenhouse gases What human activities have led to an increase in this gas? i. ii. iii. Climate change What is the difference between the terms climate and weather? 4. When the radiation hits the Earth s surface some of it bounces back into space. This means it has been How has the Earth s climate changed over the last 150 years? 5. Some of the radiation that hits the Earth s surface does not bounce back. This means it has been What is being done to prevent climate change? What negative effects might this have? 6. This radiation warms the Earth s surface and the heat energy is radiated back into space. This is called radiation.
