Climate Records need Detailed Data

Algorithms and Extremes

Given that Christy and NOAA are looking at the same data, how can there be such a large discrepancy?

The difference stems from two main factors, Christy said. First, NOAA’s chart shows average annual temperatures, while Christy focused on the highest and lowest recorded temperatures during the warmest and coldest seasons. The extremes, he said, are more relevant to climate science because they are setting the “environmental boundaries” in which plants and animals live.

The second reason for the different results, Christy said, is that NOAA employs algorithms that eliminate data points it believes could be errors or anomalies.
