Some kinds of forest fires can be beneficial to the natural environment and to people. Fire is a normal event in the natural environment. Forest fires also have some disadvantages. The scientists in this study wanted to test the smoke that comes from forest fires to discover the amount of greenhouse gases going into the troposphere.

Scientists often work with other scientists on their research projects. This is similar to what you do when you work with other students on a class project. In this study, scientists from the University of Montana, the USDA Forest Service, and the University of Wollongong in Australia worked together to study the gaseous emissions of forest fires. What are the advantages of working with others when you are trying to learn something new? What are the disadvantages?

You have probably heard a lot about global warming. Global warming is the gradual warming of the Earth. Some scientists believe that it will take decades or more to prove that global warming is or is not occurring. Other scientists believe that there is enough evidence now to claim that global warming exists. Global warming occurs when too much heat is trapped in the troposphere by certain kinds of gases. These gases are commonly called greenhouse gases. Some warming of the troposphere is necessary because the Earth would freeze without it. When greenhouse gases escape from Earth and are trapped in the troposphere, the heat is reflected back to Earth. One of the things that might cause greenhouse gases to escape into the troposphere is forest fires. The scientists in this study wanted to know the amount of greenhouse gases escaping to the troposphere during forest fires.
