Global Warming Review

							             Global Warming Review

1. Global warming is a gradual rise in the Earth’s
   average temperature. The temp has risen about 1
   degree F already.
2. The greenhouse effect is when excess gases like
   CO2 and methane trap the sun’s rays in the
   atmosphere and heat up the planet. The gases
   form a ‘layer’ that keep the sun’s heat instead of
   bouncing back into space.
3. Fossil fuels are created by living things that have
   broken down over millions of years, and they
   become oil, etc. Burning them creates harmful
   emissions like CO2 which damage our
   atmosphere.
4. The effects of global warming will be longer/
   warmer growing seasons in Canada, destruction
   of ocean habitats and animal habitats, fresh water
   supplies will be affected by rising ocean levels,
   and permafrost in the north will melt, causing
   huge amounts of CO2 to be released.
5. The Kyoto Protocol was an agreement between
   many of the world’s developed nations, in 1997.
The idea was to get each nation to pass laws that
help lower the amount of greenhouse gases that
factory owners produce.
