Global Warming

What is global warming?

Global warming refers to the fact that the Earth's atmosphere is warming near its surface simply put, it's getting hotter. The term does not imply a cause or speak to cause.

what scientists say about it?

The scientific community believes climate changes have occurred throughout Earth's history and will continue to occur in the future. Some evidence links global warming to solar activity; however, there are other theories as well.

greenhouse effect

One popular theory relates to the "greenhouse effect." Gases that make up the atmosphere are analogous to a greenhouse in that they allow sunlight to pass through, then trap much of the heat from escaping. This naturally occurring phenomenon keeps Earth's surface warmer than it would be otherwise. Human produced compounds regularly released into the atmosphere in recent years have "thickened the greenhouse wall" beyond naturally occurring levels, however. When this happens, even less heat escapes, causing temperature to rise. This is called greenhouse warming.

hanges in temperature.

While the scientific community accepts global warming as a given, greenhouse warming is more controversial. Everyone agrees that human-produced compounds like carbon dioxide, methane, chlorofluorocarbons (CFCs), and others are being released into the atmosphere, yet some argue it's not clear how this factors into the changes in temperature.
