What is Climate Change?• The Global Climate is changing.• Surface temperatures, precipitation,

sea level, ice • Greenhouse gases are increasing.• Sometimes also called Global

Warming.QuickTime™ and a

Summer Winter

Why is this Happening?

Greenhouse Gas Concentrations are rising

Page 8: What is Climate Change?. The Global Climate is changing. Surface temperatures, precipitation, sea level, ice Greenhouse gases are increasing. Sometimes

Why are Greenhouse Gases Important?

• “Blanket” that insulates the earth• Without greenhouse gases surface temperatures would be 60º F

colder than they are now.• This is because they are responsible for a phenomenon called “The

Greenhouse Effect”

• Examples of greenhouse gases are: water vapor (H2O), carbon dioxide (CO2) and methane (CH4).

What is the Greenhouse Effect?

Page 10: What is Climate Change?. The Global Climate is changing. Surface temperatures, precipitation, sea level, ice Greenhouse gases are increasing. Sometimes

Similar to your car on a hot day!

• This phenomenon is similar to the warming that occurs in an automobile parked outside on a sunny day.

• During the day, the sun’s energy passes through the car’s windshield

• Energy re-radiated from the warm car cannot pass through the windshield, and the car warms up - a lot!

Page 11: What is Climate Change?. The Global Climate is changing. Surface temperatures, precipitation, sea level, ice Greenhouse gases are increasing. Sometimes

So how are humans enhancing the Greenhouse

effect?• Burning fossil fuels puts

more greenhouse gases (like CO2) into the atmosphere.

• Increasing the concentration of these gases blocks the escape of infrared radiation.

• Too much = Climate Change.
