“When they write that temperatures are 40* degrees above normal, do they ever actual state what the temperature actually is?”
No. This illiterate author doesn’t even say the scale. (It’s Celsius).
But more. It’s not even a measured temperature. It’s made up. From the article.
“A simulation from the European Centre for Medium-range Weather Forecasting suggested that temperatures over Greenland may have peaked at around 40 degrees above normal on Wednesday.”
...so 104 F above normal in Greenland? I think someone needs to re-calibrate their simulation.
