GLOBAL WARMING BASICS

What is global warming?

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

Global warming is when the earth heats up.

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

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

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 . 4. Warmer waters and more hurricanes

3. Increased probability and intensity of droughts and heat waves

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

Affect Wildlife

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

Why is global warming happening?

Rapid CO 2 Increases

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

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

Nitrous oxide from fertilizers and other chemicals
