Global
Warming is the rise of Earth’s average surface temperature due to result of
greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or
from deforestation, which trap heat that would otherwise get off from Earth.
This is a type of green house effect. Since the early 20th century, Earth’s
mean surface temperature has risen by about 0.8 °C (1.4 °F), with just about
two-thirds of the increase happening since 1980.
It's
supposed that by the time a baby born today is 80 years old, the world will be
6 and a half degrees moderately hot than it is at the present.
