Individual What difference can we make? When faced with this question, as individuals should recognize that collectively we can make a difference.
Taking action on global warming (or climate change) is similar. In some cases, it only takes a little change in lifestyle and behavior to make some big changes in greenhouse gas reductions. For other types of actions, the changes are more significant. When that action is multiplied by the 1.3 billion people in the China. Or the 6 billion people worldwide, the savings are significant.
Look at these sentences from the text and explain why the underlined verbs are not the same tense as the reporting verbs.
1 Recent report from the IPCC warned that global warming will cause dramatic climate changes.
The Greenhouse Effect
The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60º F colder. Because of how they warm our world, these gases are referred to as greenhouse gases.

What Are Greenhouse Gases?
Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occuring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases .

The Greenhouse Effect
Without this greenhouse heating, the Earth's average temperature would be only about -73 C (-100 F); even the oceans would be frozen under such conditions,such as the Moon and the Mars.

Global Warming Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.
