Global warming has become one of the biggest controversial topics around. There are two sides to this. The people who believe its happening and the people who believe its nothing but a hoax. Many scientists say that manmade carbon dioxide (CO2), which comes from the use of fossil fuels, nitrous oxide emissions, power plants, methane, and exhaust fumes from cars all produce extra CO2 (Global Warming). Climate skeptics insist that water vapor is responsible for the current warming. Although the greenhouse effect, it is not on the UNs list of gases responsible.
It is actually called anthropogenic global warming, which is the average increase of the Earths temperature, which in turn causes changes in the climate (global warming). When the earth is warm, this may cause changes in rainfall patterns, rising of the sea levels, and also a wide range of impact on humans, wildlife and plant life. In order for the earth to become warmer, greenhouse gases trap energy inside the atmosphere, which is any gas that can absorb infrared radiation. This includes water vapor, carbon dioxide, nitrous oxide, methane, ozone, hydro fluorocarbons, perflourated carbons, and halogenated fluorocarbons.
Water vapor is extremely important to the weather and climate, water vapor is the Earths most important greenhouse gas accounting for about 90% of the Earths natural greenhouse effect, which helps keep the Earth warm enough to support life (Water Vapor). 95% of greenhouse gases are water vapor. It you get a fall evening or spring evening, the sky is clear and the heat will escape and then the temperature will drop and then you get frost. Water vapor is the dominant greenhouse gas. The water vapor feedback loop makes temperature changes caused by CO2 even bigger.
