Scroll down to the story "Climate Change: Global Warming,
The Green house effect and how it works."
Fill in the blanks regarding how global warming occurs.
1. How it works
Global warming is the_________________ over time of the Earth's
average surface __________________. Although the term "global
warming" may conjure up images of coal-fired plants and yuppies in
SUVs, the climate of the Earth has always been in flux, including
periods of sustained warming and cooling.
In general, it works like this: The _____ shines on the Earth. Most of
those rays pass through the Earth's ________________, although
some are ______________________ back into space. The surface of
the Earth absorbs the energy. Some of that heat energy is re-emitted.
The heat reflected from the ___________________ travels back up
into the atmosphere.
While on its way back up, this heat can be absorbed by the
__________ like carbon dioxide and methane, commonly known as
______________ gases. These are naturally occurring gases as well
as those from burning fossil fuels; they ________ the heat, warming
up the Earth's surface even more. Without naturally occurring
greenhouse gases, the Earth would be about 33 C colder than it is, a
temperature hostile to human life.
Over thousands of years, changes in atmospheric conditions, such as
gas concentrations, and singular events – volcanic eruptions, for
instance – have caused climate change. Most of those changes have
taken hundreds or thousands of years to play out.
But climatologists now agree that the world appears to be in a
sustained, relatively _________ period of _____________.
