Global warming is defined as the rise in temperature of the earth caused by an increase in greenhouse gases such as carbon dioxide, CFCs, ozone, methane and nitrous oxide in the atmosphere. Some causes of global warming include industrialization, urbanization, atmospheric pollution and an influx of greenhouse gases. Impacts of global warming include increasing temperatures on land and sea, melting of polar ice and snow, sea level rise, loss of organisms and biodiversity, floods and droughts, increased ocean temperatures, and shifting life zones towards polar regions. Recommended actions to reduce global warming include using less plastic and fossil fuels, afforestation, and reducing air conditioner, refrigerator and CFC usage.
