Description

Life on the earth is possible pa11ly because some gases, such as carbon dioxide (CO2) and water vapor, which naturally occur in the Earth's atmosphere. they tend to trap heat- like a greenhouse does. It has been felt that the humans are greatly adding to the presence of such gases, commonly referred to as greenhouse gases (GHGs), by burning fossil fuels and through other industrial activities as well as various kind of land use, such as deforestation.

Anthropogenic GHGs emissions (those that are produced, induced or influenced by human activity) work against us when they trap too much sunlight and block outward radiation. Many of the scientist worry that the accumulation of these gases in the atmosphere has changed the climate and will continue to change it. Potential negative climate risks include more severe weather patterns; hobbled ecosystems, with less biodiversity; changes in patterns of draught and flood, with less safe drinking water; inundation of coastal areas from rising sea level; and greater spread of infectious disease such as malaria; yellow fever, and cholera. On the positive side, climate change might benefit agriculture and forestry in various locations by increasing productivity as a result of longer growing seasons and increased fertilization.
