WHO IS THE REAL ENEMY OF OUR MOTHER EARTH?
CLIMATE CHANGE
Earth's climate is influenced by different forces as
discussed in the previous lesson. When the sun rises, the
planet warms as it receives radiant energy. When
volcanoes erupt, pyroclastic materials are suspended into
the atmosphere which reflects sunlight and the planet
cools down. Obviously, the past climate change was
caused by natural forces.
CLIMATE CHANGE
At present, climate change as a problem, is believed to have
been caused by the human expansion of the greenhouse
effect. Greenhouse gas (GHG) is a gas in the atmosphere
that absorbs and emits radiation within the thermal infrared
range. This process is the fundamental cause of the
greenhouse effect - a warming that results when the
atmosphere traps heat radiating from Earth toward space.
