Debating "Global Warming"

The controversy over climate change has shifted focus over the years. The main debate now is one of interpretations of science. Frequently, the method of predicting future trends is based on computer modeling, and many scientists argue that there are too many variable factors to effectively see the big picture. While some scientists who believe human activity is to blame for global warming are ready to outline specific actions to prevent more damage, skeptics are looking for more evidence to warrant change.

Many sources mark the Industrial Revolution as the beginning of current global warming. But while many scientists agree that air pollution at that time started the current trend and that human activity is to blame, others believe that climate change is part of the natural global progression, and that human activity will neither worsen nor improve our situation. Some experts have argued that the use of fossil fuels, although it may be a significant cause of global warming, is unavoidable in modern society.

People can't directly sense global warming, the way they can see a clear-cut forest or feel the sting of urban smog in their throats.
