Video: Ice cores

The following video talks about the use of Proxy records, specifically ice cores. It talks about how this data can be used to find out what Carbon Dioxide levels were like up to hundreds of thousands of years ago. It shows how people actually work with ice cores, being able to tell seasons and specific years and the stories they tell, such as volcanic explosions and changes in levels of Carbon Dioxide. This is something that we watched as part of an assignment, but was very interesting to me as I have always been interested in ice cores, if you would like to watch click below.
