Extra
carbon dioxide in the atmosphere enhances a natural process known as the
greenhouse effect. Greenhouse gases, such as carbon dioxide, absorb heat and
release it slowly. Without this process, Earth would be too cold for life to
survive. Over the past 200 years mankind has increased the proportion of
sphere, primarily by burning fossil fuels. The higher levels of greenhouse
gases causing our planet to warm-global warming. Also gradual increase in the overall
