You hear a lot about averages and normals in weather forecasts — above-average temperatures, below-normal snowfall. Well, those averages are about to be updated. And there’s concern the new normals could mask the magnitude of climate change.

While the decennial process helps climate scientists look at long-term trends, “it’s going to be harder for [meteorologists] to come on air and say a given day was above average because we’ve shifted to this higher normal in this warmer world,” said Heidi Roop, assistant professor of climate science at the University of Minnesota.
