Proxy data are natural climate records that provide evidence of past climates. Data are needed because it is only possible to measure past climates by looking at records of recent climates. This is why these records are important. The proxy data is information about past climates that goes beyond the instrumental record and thus expands our understanding of climate.

I hope this helps you
