This is mainly due to the enormous amounts of coal, oil and natural gas that people burn. These fuels release a gas called carbon dioxide into the air. Carbon dioxide is called a greenhouse gas because it helps to trap heat in the Earth’s atmosphere.
Because greenhouse gas levels in the atmosphere are rising fast, Earth is warming very quickly. When the Earth warms, it has many effects:
The ice at the North Pole is melting and Vixen, the smallest reindeer, is afraid.
Santa’s toy workshop will soon fall into the sea, he has nowhere to go, and the elves who make the Christmas toys for him are threatening to leave.They’re terrified of an old enemy, but won’t say who it is, only that the dark is rising again.
Will this be the last Christmas?
