The document is a presentation by the group "Atom 2π" on climate change. It introduces the group members and states the topic of the presentation is climate change across the world. It goes on to define climate change and the greenhouse effect, and discusses the causes of climate change including carbon dioxide and methane emissions. It ends by suggesting ways to reduce climate change such as using cleaner renewable energy sources like solar, wind, hydro and geothermal power.

4. What Is Climate Change ??

5. -Climate change, also called
global warming, refers to the
rise in average surface
temperatures on Earth…..

6. CLIMATE CHANGE VIDEO

7. Climate Weather
.Temperature
.Temperature .Specific moment
.Long Period of Time .Example: It is a hot day outside
.Example:warm summer,cold winter
What Is Difference Between Weather and Climate

8. What Is The Greenhouse Effect And Why
To Much Of It A Bad Things?
.When the atmosphere traps sun rays
.Sun rays are only energy
.Energy heats the earth
.Earth heating means less food caused by drought

10. What Is Causing Climate Change and
How Do You Know?
 .Grass isn’t getting cut
 .Grass release CO2,a camical that’s heats the earth
 .Trash is getting dumped into major water sources
 .The water heats quicker
 .The quicker the water heats ,the more water vapor gets into the air

12. How To Reduce Climate
Change ??

13. Reducing climate change: Cleaner alternative
energy sources. One important way to
fight climate change is to use alternative
sources of renewable energy which will not
release harmful emissions. Some of these
cleaner sources of renewable energy include
wind energy, solar energy, water or
hydropower, biomass, and geothermal energy.
