An inter-glacial period is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age.
2What is the pattern of climate change from the beginning of the Quaternary period to the present day?Since the beginning of the Quaternary period, the temperature has fluctuated up and down
3Range of evidence proving climate change:Ice cores:
Different layers of ice can tell show the average temperature and what the world was like
ocean sediment:
Different layers of ocean sediment can show us what the world was like by the texture
diaries and paintings:
Paintings can show us
sea ice positions
