Global Warming- Fact or Myth?

1875- Austria
2004 - Austria

Did you know?
  • If all the worlds ice melted, sea levels would
    rise by more than 30m. Vast areas of land, eg
    parts of USA and India, would be flooded.
    Thousands of people could die.
  • Polar bears may only be around for another 100
    years because global warming is destroying their
    habitat.
  • A global temperature rise of 1 degree (Celsius)
    will affect wheat and rice production. These are
    our two main food crops. Millions of people could
    starve.

What does a house covered in Christmas lights
have to do with polar bears living at the North
Pole?

A house like the one above, with so many light
bulbs glowing, will use up lots of energy and
contribute to global warming. More and more
people are celebrating Christmas by decorating
their homes, inside and out. So these millions of
light bulbs glowing on one side of the world can
have a big effect on animals far away.
