The case related to the environment is climate changes such as the greenhouse effect. The greenhouse effect has happened around us locally. A greenhouse gas is a gas that absorbs and emits radiant energy within the infrared range. Besides, the primary greenhouse gases in Earth's atmosphere are water vapor (H2O), Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (NO2), and Ozone (O3). Without greenhouse gases, the average temperature of Earth's surface would be about 8° (0° F). In the later 1800s, atmospheric scientists have first used the word the greenhouse effect. At that time, the greenhouse effect is used to designate the naturally happening functions of trace gases in the atmosphere and did not have any negative implications. Unfortunately, it did not improve until the mid-1950s that the case greenhouse effect was tender toward concern over climate alteration. However, in contemporary decades, the greenhouse effect will be negative terms. Furthermore, in 1827, the greenhouse effect was first discovered by Joseph Fourier. This experiment was verified by John Tyndall in 1861 and quantified by Svante Arrhenius in 1896.
