Horrors! We simply MUST charge the people a tax to stop the ice from melting in summer!!!!!
Now, stop and think for just a moment before you buy that bottle of snake oil... and there will be a quiz next period.
During the winter, ice sheets grow.
If, during the following summer, those ice sheets do NOT break off and melt in summer, then grow again next winter, do not melt in summer, then grow again next winter, then do not melt in summer, then we are headed into an ice age, aren't we? (Maybe we are; they are having ice storms in Kenya right now).
