Viewpoint: Yes, There Is Strong Evidence That Most of the Global Warming Observed Over the Last 50 Years Is Due to Human Activities.

The Greenhouse Effect

The greenhouse effect is not all bad. With the blanketing of greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide, and tropospheric ozone) the planet is kept about 59°F (15°C) warmer than it would be without the cover. Water vapor is by far the most abundant greenhouse gas. The greenhouse effect gets its name because a layer in the atmosphere acts like the glass in a greenhouse, letting the Sun's light energy in, but preventing reflected lower energy heat radiation from escaping.

All the greenhouse gases that occur naturally are also produced by human activities, thus increasing their levels in the atmosphere at an accelerating pace. In addition to...
