Read this paragraph and answer the question below.

We should all do more to preserve our planet.

Some scientists believe the earth's temperature has always fluctuated.

The earth is getting hotter very quickly.

There may not be enough conclusive evidence about what causes global warming.

Global Warming

Al Gore focuses on the trend towards global warming and says that the earth is getting hotter very quickly. Gore presents evidence that links fluctuations in the earth's temperature and climate changes to causes such as air pollution and increased carbon dioxide in the earth's atmosphere. However, some scientists say that the earth's temperatures have always fluctuated, and that serious changes could take many more years. Clearly however, the main issue here is that we should all be focusing on what we can do to prevent global warming.
