What is global warming?
The Planet Is Heating Up—and Fast
The earth heats up (the temperature rises)=>It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature Source: http://www.epa.gov/globalwarming/emissions/index.html Cut your utility bills by purchasing energy-efficient appliances, fixtures, and other The average house is responsible for more air pollution and carbon dioxide emissions than .
What is the greenhouse effect?
- The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. The heat and light can get through the atmosphere, but it can’t get out.
Sometimes the temperature can change in a way that helps us If so, are the actions of mankind to blame for earth's temperature increases? What can/should be done about these issues? History of Earth's Climate..
=>During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat. What is global warming doing to the environment?
Makes the sea rise : the water covers many low land islands, the plants and causes some of them to die so, the animals lose a source of food, along with their habitat,but people lose two sources of food, plant food and animal food
10. Global warming, is harming and killing algae in the ocean.
=>Fewer algae is a problem because there is less food for us and many animals in the sea.

Many pollutants are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.
- The pollution that causes global warming is linked to acid rain. =>Acid rain
Another thing that makes global warming worse is when people cut down trees. Trees and other plants collect carbon dioxide (CO2), which is a greenhouse gas.
Global warming=>it is also destroying many huge forests,many more fires that wipe out whole forests.
Climate change (cc) or global warming - assemble
Carbon dioxide is the air that our body lets out when we
breathe What has this got to do with global warming then?? Power stations release huge amounts of carbon dioxide as they burn coal (a fossil fuel) in order to produce electricity. Just think for a moment about how much electricity we all use….
With fewer trees, it is harder for people to
breathe because there is more CO2 in the air. Plants
collect the CO2 that we breathe out, and they give back
oxygen that we breathe in.
With less trees and other
plants, such as algae, there is less air for us, and more
greenhouse gases are sent into the air.
What are people doing to stop global warming?
Carpooling=>is driving with someone to a place that you are both going to The essential science behind Climate Change – for students and teachers Put simply – climate tells you what clothes to buy but weather tells you what clothes to wear. The evidence for this comes from many sources – see slide 17..

Another thing that people are doing is being more careful about leaving things turned on like the television, computer, and the lights. The Clean Air Act is making many companies change their products to decrease these problems. Part of the law says that you may not put a certain amount of pollutants in the air.
The Clean Air Act has also made car companies change some of the things inside of the cars. While cars make more than half of the world’s smog.
- Reducing cars, buses, and trucks which are also responsible for over 50% of dangerous chemicals let into the air 16 Global Warming Presentation 2009 - Free download as Powerpoint Presentation (.ppt), Higher Colleges of Technology Abu Dhabi Men's College. Course .
Ozone - Ozone is produced when other pollution chemicals combine. It causes many different kinds of health issues dealing with the lungs.
