world is always changing. Look out your window long enough, and you
might see the weather change. Look even longer, and you'll see the
seasons change. The Earth's climate is changing, too, but in ways that
you can't easily see.
Warming as well as freeze-overs have always been a natural process for
the earth, as early as when the earth began its formation. But today's
kind of global warming simply means the Earth is getting warmer from
heat-trapped gasses (of which some continue to be natural and produced
by the earth itself). But human activity has caused a significant rise
in more unnatural, man-made gasses. This has caused the natural process
of global warming to shift into high-gear. Since the Industrial
Revolution came about and as human populations around the world continue
to grow, so does global warming...exacerbated by pollution, heat from a
concentration of roads and buildings in urban areas, fumes and fossil
fuel burning from factories, vehicles, and other forms of gas producing
technologies; in general, most of what we consume [that is not naturally
grown] or produce contributes to unnatural gasses in our atmosphere).
Gasses are also a global warming phenomena. This is caused by heat
being trapped by objects (such as buildings and roads). Unfortunately,
warmer temperatures are causing other changes around the world, such as
melting glaciers and stronger storms - just look at the eastcoast storm
Sandy and the tornado that struck Oklahoma killing hundreds of people.
These changes are happening because the Earth's air, water, and land are
all linked to the climate. The Earth's climate has changed before, but
this time is different. People are causing these changes, which are
bigger and happening faster than any climate changes that modern society
has ever seen before.
