snow, permafrost and sea ice
Increase in albedo effect when there is more snow and ice, less when there isn't, snowball earth and runaway global warming

-
ice sheet is a body of ice greater than 50,000km2
ice cap is a body of ice less than 50,000km2 which is the origin of more than one glacier
Little Ice Age
-
-
glacier advance mainly affected property whereas ice avalanches and glacier related floods affected lives as well
causes of little ice age -
- not man made climate change,
- variability in solar output,
- changes in large scale atmospheric pattern
- volcanic eruptions
ice avalanches - frontal block filure, - ice slab failure, ice bedrock failure
