Slide 1: 

Why Global warming ?

What is global warming? : 

What is global warming? The changes in the surface air temperature, referred to as the global temperature, brought about by the enhanced greenhouse effect, which is induced by emissions of greenhouse gases into the air.

How Global Warming Works : 

How Global Warming Works

Slide 4: 

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

Slide 5: 

What’s the difference between “global warming” and “climate change”?

Difference : 

Difference 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.

Effects of Global Warming : 

Effects of Global Warming Increased Temperature Rising Sea Level

2007 Reductions in CO2 Per Year Gigaton Carbon Billions of Metric Tons Carbon Our Goal

What’s being done now to reduce our emissions? : 

What’s being done now to reduce our emissions? Solar Power Wind Power Fuel-Efficiency

We can stop global warming! : 

We can stop global warming!

Slide 22: 

What can you do to help solve the problem?

Simple Things To Do : 

Simple Things To Do Turn off your computer or the TV when you’re not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.

Be Bulb Smart—Use CFLs : 

Be Bulb Smart—Use CFLs Incandescent Compact Fluorescent 500 lbs. of coal What’s the difference? 1,430 lbs. CO2 pollution avoided $30 saved

Simple Things To Do : 

Simple Things To Do Dress lightly when it’s hot instead of turning up the air conditioning. Or use a fan. Dress warmly when it’s cold instead of turning up the heat. keep the air filters on your AC and furnace clean. Walk short distances instead of asking for a ride in the car. Plant a tree. Recycle.

Top 10 Things You Can Do to Reduce Global Warming : 

Top 10 Things You Can Do to Reduce Global Warming . Reduce, Reuse, Recycle . Use Less Heat and Air Conditioning . Change a Light Bulb . Drive less and drive smart . Buy Energy-Efficient Products . Use Less Hot Water . Use the "Off" Switch . Plant a Tree . Implement Audit reports from Utility company . Encourage others to conserve.
