PRESENTATION OUTLINE
Global warming is about average temperature around the planet.
Global warming does not mean that there won't be any more cold days.
Weather is whats is happening outside at a certain place and at a certain time.
Global warming is a change in the world's climate, which is the pattern of weather over long periods of time.
Global warming is affected by CO2, methane, nitrous oxide and ozone.
results in Global warming.
When sunlight hits earth land and water soaks up some of the energy and the rest of the energy is reflected, like a greenhouse the greenhouse gases trap the heat which results in Global warming.
That effect is called the greenhouse effect without it earth would be a cold lifeless piece of rock.
Our modern world depends on burning fossil fuel which creates greenhouse gases that traps heat, which accelerates global warming.
Agriculture also plays an important role in climate change, as we keep cows and other animals for milk and meat they release methane which traps 21 times more heat than carbon dioxide.
The problem isn't just about greenhouse gases, it is also that we destroy earth’s natural ability to remove those gases by cutting trees down and that releases all the gases that the trees stored up.
The water absorbs most of the sunlight which destroys coral reefs that are home to many sea species.
Another problem with global warming is that polar ice caps are melting which causes sea levels to rise and might cause more floods and tsunami.
There is also a solution to climate change, we can walk or bike instead of getting a ride to places, we can also use more natural energy sources that don't pollute such as solar energy, wind energy and water energy.
