Summative assessment for the unit "Natural Disaster" Task 1. Read the text about global warming Experts in climatology are extremely concerned about the climate changes. Climate changes have happened on our planet before. For example: there had been several ice ages. 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 rapidly. The major problem is warming up the planet. 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 carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases, create a greenhouse effect, by which the heat of the 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. 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? 5)Express your opinion: Is global warming true or false? Give reasons
