It should NOT be confused It should NOT be confused with climate changewith climate change
What is global warming?
GLOBAL WARMING is the increase of the
Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
CLIMATE CHANGE is a broader term that
refers to long-term changes in climate, including average temperature and precipitation.

Increase Increase in the average measured in the average measured temperature of the Earth's surface air and temperature of the Earth's surface air and oceans oceans
How Global Warming Works
Fossil fuels (coal, oil, natural gas)
Carbon Dioxide (CO2)
Greenhouse gases
CAUSES OF GLOBAL
WARMING
Pollution from coal, natural gas, and oil
CO2 from
airplanes & vehicles
POPULATION POPULATION INCREASEINCREASE
DEFORESTATIODEFORESTATIONN
Increased CO 2
results in
The Sun’s energy passes through the car’s windshield.
This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.
Example of the Greenhouse Effect
Global warming
causes
Melting of glaciers
Polar Bear Extinction
Warmer waters and more hurricanes
Increased probability and intensity of droughts and heat waves
Increased Temperature
MeltingPolar ice caps
