Frequently Asked Questions About Global Warming
There has never been much doubt that the release of carbon dioxide, a natural constituent of the atmosphere and a byproduct of fossil fuel combustion, has some warming effect on the planet. But the impact of man-made emissions of this greenhouse gas may be minor. The real issues are whether or not the release of carbon dioxide is a significant factor relative to natural temperature variability, what the likely consequences of warming would be, and what should be done about it. To better explain these issues, this paper provides answers to frequently asked questions about global warming.
