200 YEARS OF CLIMATE CHANGEGreenhouse gases and the END OF THE WORLD!!!!!!!Well, Floods and Droughts at least.

None Like It Hot!

▪ What happened in this video?

▪ What is the cause of the problem?

▪ What impossible solution is presented?

Greenhouse Gases

These are gases that absorb infrared radiation

Chlorofluorocarbons and CO2 and Nitrous Oxide and Methane, etc.

Turns solar radiation into heat in the atmosphere

Heat absorbed by planet’s surface and bounces back, reradiates in all directions

Traps much heat within the planet’s atmosphere

Here’s How It Works

History of Greenhouse Gases

▪ What was happening in history around the time of the rise in carbon emissions?

▪ What caused this rise?

▪ Suggest what this chart will read in the year 2100.

Human Impact

▪ Remember why it gets colder the higher the elevation?

▪ Sort of the same thing with Greenhouse Gases.

▪ We are adding a tremendous amount of substance to the atmosphere of Earth, everyday, everywhere, all of the time.▪ CFC’s (chlorofluorocarbons) from Acs and refrigerators▪ CO2 from breathing, huge population and deforestation▪ Methane from bacteria breaking down organics, end of digestion▪ Nitrous Oxide from fuel consumption and fertilizers▪ Water Vapor/Humidity from increased heat

Analyze the charts: Where are IC’s and DC’s now? Where are they predicted to be in the future? Why?Suggest why Japan has a lower per capita emission rate than the United States.

Enjoy this scenic photo of downtown Beijing, China.

China is a Developing Country experiencing dangerous levels of air pollution.

Heat Projections: Melting Ice

Contrast these two images. What is different?

Compare these two images. What is similar?

Where is most of the heat change occurring?

What is found in that region?

How will that heat change effect Earth?

Melting ice diminishes the range polar bears can hunt in.

Their habitat shrinks, they get trapped on shrinking ice sheets, they end up like this poor guy. It is unknown how many bears are drowning in the Pacific Ocean each year.

Florida: USA prediction

Suggest ways a government could prepare for the flooding effect predicted here?

Will Indonesia be effected similarly or differently?Explain. Suggestions?

Leaving a lighter CARBON FOOTPRINT.Explain 10 specific ways we can.
