In summer, the amount of CO2 gas that can remain dissolved decreases with increasing temperature. The increasing CO2 gas pressure can break the can.
In as freezer, the higher volume of frozen H2O will ripe the can open. Aluminum cannot expand enough without breaking.

Last year, I left a case of canned soday in my cooler out on the deck. Winter came, and freezing cold came. I found out not only aluminum can't handle the expansion, but that soda cans are made thinner than just a few years ago. What a mess. Don't leave your soda cans in the cooler outside.
