So what could happen?

This poor polar bear has been stranded on this block of ice  because of the ice caps melting.

•     Snow and ice would melt at the ice caps and this would make the sea rise.
•           Lots of cities could flood   and that could flood or destroy people’s homes.
•           More hurricanes and storms could come because of the changes in the atmosphere!
•           Some animals and plants could become extinct because the earth will be too hot for them and with plants being extinct we wouldn’t have as much oxygen.
•           Some rivers and lakes could dry up and that means we wouldn’t have as much water which would cause more droughts
•          There will be less water for drinking, washing and swimming. So a lot of us could be smelly from not washing or die from thirst because a lot of drinks need water in them.
