What could happen?


If the Earth gets hotter, these are some of the things that could happen:

  • Water expands when it's heated so sea levels could rise.

  • Sea levels could also rise due to the melting of the glaciers and sea ice.

  • Animals like polar bears - which live on the ice - might die out.

  • There could be more floods, especially near the coast and rivers.

  • Places that usually get lots of rain and snowfall might get hotter and drier.

  • Lakes and rivers could dry up.

  • There would be more droughts, making it harder to grow crops.

  • Less water would be available.

  • Some plants and animals might become extinct because they cannot cope with higher temperatures.

  • Hurricanes, tornadoes and other storms which are caused by changes in heat and water evaporation may get more common.
