How do ice cores act as evidence of climate change?

• The gases trapped in the ice from years last can show CO2 concentrations from that year, giving us temperature readings

• Observing maximum and minimum ice coverage can show us the temperature of the oceans

• Past accounts of climate can show us what the climate was like in the past where we have no data from

• Started in the 1850s we have been able to measure global temperature through thermometres
