Long data sets for temperature records over time allow for temperature and climate conditions over time to be determined and analysed.
The validity of these long data sets can be tested by comparing these datasets to other long data sets to determine whether the two data sets demonstrate a correlation (not necessarily a causation), for example comparing long datasets for fossil fuel consumption and temperature records to see if they have a correlating relationship that may support a theory for their causation.
Limitations:
Considering that equipment used to measure temperature overtime has developed, earlier temperature records taken in long datasets are likely to have used less developed and accurate equipment to take these measurements. This therefore limits the validity of these earlier measurements and consequently questions the realibity of any conclusions made from analysis of these long data sets for temperature records over time.
