are greenhouse gases harmful
The Environmental Protection Agency declared today that carbon dioxide and other greenhouse gases are harmful to people and the environment. The administration will not ignore science or the law any longer, nor will we avoid the responsibility we owe to our children and our grandchildren, EPA Administrator Lisa Jackson said.

The heat caused by infrared radiation is absorbed by greenhouse gases such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere. Scientists generally divide these helpful actions (known as. “climate change mitigation”) into three categories: reducing CO. 2. and other. harmful greenhouse gas emissions (the release of these gases into the atmos -. phere), reducing the amount of sunlight that reaches the earth’s surface, or. removing CO. Ozone is technically a greenhouse gas because it has an effect on global temperature. However, at higher elevations in the atmosphere (stratosphere), where it occurs naturally, ozone is needed to block harmful ultraviolet light. The greenhouse effect often gets a bad rap because of its association with global warming, but the truth is we couldn't live without it. Life on earth depends on energy from the sun. About 30 percent of the sunlight that beams toward Earth is deflected by the outer atmosphere and scattered back into space. Water vapor is the most abundant greenhouse gas. Most scientists believe that water vapor produced directly by human activity contributes very little to the amount of water vapor in the atmosphere. Therefore, the U.S. Energy Information Administration (EIA) does not estimate emissions of water vapor. At lower elevations of the atmosphere (troposphere), ozone is harmful to human health and is a pollutant regulated independently of its warming effects. Greenhouse gases are transparent to incoming (short-wave) radiation from the sun but block infrared (long-wave) radiation from leaving the earth's atmosphere. Although greenhouse gases make up only about 1 percent of the Earth's atmosphere, they regulate our climate by trapping heat and holding it in a kind of warm-air blanket that surrounds the planet. This phenomenon is what scientists call the greenhouse effect.
Yes,greenhouse gases are harmful to people and the environment.
