Students’ Questions about Environment Page 3

1. Global warming is one of the most pressing environmental issues of our time.

2. It is important because it has the potential to cause great harm to our planet and its inhabitants.

No one knows for sure when global warming will end the world. However, it is clear that the world is slowly but surely being destroyed by it.

1. Use less energy.
2. Use renewable energy.

Global warming is the long-term rise in the average temperature of the Earth’s climate system. It is a major aspect of current climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.

Global warming is the gradual increase of the Earth’s average surface temperature. The main component of global warming is the increased emission of greenhouse gases.

The greenhouse effect and human activity are the two main causes of global warming.

1. To stop global warming, we need to stop emitting greenhouse gases into the atmosphere.
2. We can do this by using less fossil fuels, planting trees, and protecting our forests.

There are two major types of physical evidence for climate change: direct and indirect. Direct evidence includes things like temperature records and the presence of greenhouse gases in the atmosphere. Indirect evidence includes things like the impact of climate change on plant and animal populations.

There are many ways to help climate change. Some things individuals can do are: drive less, waste less food, compost, recycle, and use less water.

Climate change is already having an impact on our planet and its inhabitants. The effects of climate change include more extreme weather events, rising sea levels, and changes in ecosystems.
