The document discusses global warming and its causes. It notes that while greenhouse gases like carbon dioxide and methane help keep the planet warm, excess amounts from activities like burning fossil fuels, agriculture, deforestation, and CFCs can overheat the Earth. This leads to problems like more extreme weather, threatened food supply from drought, and climate change impacts. Some solutions proposed include transitioning to clean energy like solar and wind, reducing and offsetting emissions through reforestation, and individual behavior changes around reuse, recycling, and transportation.

1. Global Warming

5.  78% Nitrogen
 21% Oxygen
 1% Miscellaneous gases (incl Carbon Dioxide, Methane and
other Greenhouse Gases)
 The greenhouse gases help keep Earth warm – without it the
entire Earth would be frozen over
 But if we have too much Greenhouse gases we can
overheat….

7.  Burning of fossil fuels releases Carbon Dioxide and Nitrous
Oxide into the Atmosphere
 Methane from agricultural activity
 CFC’s from past use of aerosols
 Deforestation means trees (who would normally absorb the
extra greenhouse gases) cannot do so

8.  Climate Change – More droughts and extreme storms

9.  Agricultural impacts – food supply threatened as land dries
out

11.  Clean Energy – no greenhouse gases (e.g Solar and
Wind Power)
 Reduce deforestation
 Plant new forests
 Reduce, Reuse and Recycle materials
 Use energy efficient appliances
 Behaviour change – walk/cycle instead of driving
