Global Warming
• The Earth's climate has changed many times in the
past. Subtropical forests have spread from the south
into more temperate (or milder, cooler climates)
areas. Millions of years later, ice sheets spread from
the north covering much of the northern United
States, Europe and Asia with great glaciers. Today,
some scientists believe human beings are changing
the climate. How can that be?

• Over the past few centuries, people have been
burning more amounts of fuels such as wood, coal,
oil, natural gas and gasoline. The gases formed by the
burning, such as carbon dioxide, are building up in
the atmosphere. They act like greenhouse glass. The
result some experts believe is the Earth heating up
and undergoing global warming.

The Greenhouse Effect traps heat inside the Earth’s
atmosphere. This causes our climate increasing in
temperature. This is known as Global Warming.

Global warming could cause:
• flooding as polar ice caps melt, raising
sea levels
• extreme weather events due to shifting
ocean currents
• deserts to spread across Europe as land
dries up
