Hint.
Think about how they are measured. The main source for temperature is tree ring data. Is it as easy to tell the temperature from tree rings as it is to measure \(\text{CO}_2\) trapped in layers of a glacier?

Hint.
When were thermometers invented? Since when have we been recording temperatures all around the globe?
