CLIMATE CHANGE: HOW THE HOMO SAPIENS HAVE CONTRIBUTED By Ernest Ebo Jackson TERM PAPER Climate change refers to change in average weather patterns and can be caused by both natural processes and human activities. In the past‚ the earth’s climate has been affected by natural factors such as changes in solar output and the discharge of volcanic ash. In fact‚ the planet has been through many periods of cooling and warming. The last period of major cooling ended about 10‚000 years ago.

Climate is a measure of the average pattern of variation in temperature‚ humidity‚ atmospheric pressure‚ wind‚ precipitation‚ atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate is different from weather‚ in that weather only describes the short-term conditions of these variables in a given region. A region’s climate is generated by the climate system‚ which has five components: atmosphere‚ hydrosphere‚ cryosphere‚ land surface‚ and biosphere

In reviewing the poem “Mexican is not a noun” written by Francisco X. Alarcon‚ it was an interesting take on how Alarcon thinks the word is viewed as a verb rather than a noun or an adjective.
