Read the passage and choose the best answer to each of the following questions.
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 rapidly.
The major problem is, perhaps, that the planet is warming up. According to some experts, this warming, known as global warming, has been occurring for the last 10,000 years. The effects on the planet are very serious. Rising global temperatures could give rise to 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 the sun is trapped. This leads to the warming up of the planet. Besides, part of the problem of rapid climate change has also been caused by too drastic deforestation. Humans have been destroying vast areas of rainforests which are considered the planet's lungs to serve their need for wood and land.
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. Sadly, the targets are not being met.
