Global warming refers to an increase in the Earth’s average surface air temperature. Global warming and cooling in themselves are not necessarily bad, since the Earth has gone through cycles of temperature change many times in its 4.5 billion years. However, as used today, global warming usually means a fast, unnatural increase that is enough to cause the expected climate conditions to change rapidly and often cataclysmically.

Observations of Ozone Depleting Gases

Ozone Depleting GasesThe ODGI is estimated directly from observations at Earth’s surface of the most abundant long-lived, chlorine and bromine containing gases regulated by the Montreal Protocol (15 individual chemicals). These ongoing surface-based observations provide a measure of the total number of chlorine and bromine atoms in the atmosphere that are likely to reach the stratosphere and contribute to ozone depletion in the near future.... selengkapnya »
