GLOBAL WARMINGBASICS

What is global warming? : 

What is global warming?

Slide 4: 

Global warming is when the earth heats up. It happens when greenhouse gases such as ,water vapor carbon dioxide and methane trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. ,nitrous oxide

Slide 5: 

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. Greenhouse Effect

Effects of Global Warming : 

Effects of Global Warming

5. Spread of disease : 

5. Spread of disease As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them.

As the temperature of oceans rise, so will the probability of more frequent and stronger hurricanes. : 

As the temperature of oceans rise, so will the probability of more frequent and stronger hurricanes. 4. Warmer waters and more hurricanes

3. Increased probability and intensity of droughts and heat waves : 

3. Increased probability and intensity of droughts and heat waves

Slide 10: 

Hurricanes and diseases cost money which affect a country’s economy 2. Economic Consequences

Slide 11: 

1. Polar ice caps melting Raise sea levels. Raise temperatures Affect Wildlife

Wildlife Effects : 

Wildlife Effects Polar Bears Require pack ice to live Might eventually go extinct in the wild Sea turtles Breed on the same islands astheir birth Could go extinct on some islandsas beaches are flooded Other species may go extinct as rainfall patterns change throughout the world

What’s the proof that global warming is taking place? : 

What’s the proof that global warming is taking place?

Drought in Africa : 

Drought in Africa Lake Faguibine Lake Chad

Colorado River, Arizona : 

Portage Glacier, Alaska Colorado River, Arizona

Why is global warming happening? : 

Why is global warming happening?

Slide 17: 

Rapid CO2 Increases

Burning of Fossil Fuels in plants, factories, cars and houses : 

Burning of Fossil Fuels in plants, factories, cars and houses

Methane from rice paddies both ends of animals, garbage in landfills and mining operations : 

Methane from rice paddies both ends of animals, garbage in landfills and mining operations

Nitrous oxide from fertilizers and other chemicals : 

Nitrous oxide from fertilizers and other chemicals

Possible Solutions to Global Warming : 

Possible Solutions to Global Warming

Mitigation of Global Warming : 

Mitigation of Global Warming Conservation Reduce energy needs Recycling Alternate energy sources Nuclear Wind Geothermal Hydroelectric Solar Fusion

Slide 23: 

Together we can make a big change!

TOGETHERWE CAN STOP global warming! : 

TOGETHERWE CAN STOP global warming!

Slide 25: 

Keep rooms cool by closing the blinds, shades, or curtains. Conserve electricity! DO NOT leave appliances on standby Turn off the lights when you leave.

Use CFLs : 

Use CFLs Incandescent Compact Fluorescent What’s the difference? 1,430 lbs. CO2 Pollution avoided 500 lbs. of coal 1400 Php saved

Slide 27: 

Avoid turning up the air conditioner. Instead dress lightly or use a fan. Keep the air filters on your AC clean. Walk short distances instead of asking for ride in the car.

Slide 28: 

Plant a tree Reduce, Reuse, Recycle
