What is global warming?
- humans cause it, we release heat-trapping gases in our everyday lives
- these gases are called greenhouse gases
- the gas is higher than ever
- greenhouse gases trap heat and don't let it out of atmosphere
- gases let light in but trap heat
- more gases there are, more heat gets trapped
Why is it a problem? The climate is changing faster, so living things can not adapt fast enough.
What conrtibutes to global warming?
- burning of coal
- fossil fuels
A Polar Bear in Antarctica struggles to stay on ice.
A penguin struggles to stay up.
17 years later, the mountain has lost a tremendous amount of ice.
- less fossil fuels used
- less heat trapped
- public transport will upgrade or be better
- fossil fuels can be used for other things
- money saving
- can be costly
- transportation systems can still let out bad greenhouse gases but not as much as before
- not all people will want to use public transportation
- any sickness could spread easily
But, which one is better?
The problem is global warming, and the solution is to reduce emissions. Not only does this reduce the heat trapping gases, it can reduce things like tropical deforestation and can reduce U.S. oil use.
