Climate Change as a consequence of the cumulative emission of carbon dioxide (a by-productof fossil fuel use) and other chemicals over the past two centuries, the concentration of these gases in the global atmosphere is growing dramatically. These chemicals capture more solar energy within the atmosphere, and hence average global temperatures are rising – by about a full degree Celsius (on land) over the past half-century. The rise in global temperatures is causing many serious consequences, including changes in rainfall, rising sea levels, extreme weather and storms, and changes in plant and animal habitats.
According to Department of Defense Dictionary of Military, Climate change refers to the variations in average weather conditions that persist over multiple decades or longer that encompass increases and decreases in temperature, shifts in precipitation, and changing risk of certain types of severe weather events.
