> Those are some of the results of a new study published today in the journal Science Advances that reports the Arctic has warmed by 0.75 degrees Celsius (1.35 degrees Fahrenheit) in the last decade alone. By comparison, Earth as a whole has warmed by nearly the same amount, 0.8 degrees C, over the past 137 years.
I can think of two issues with statements like this, especially the second part:
1. Measurement techniques have changed a lot over the last 137 years. Just reading the article, it's far from clear how these differences are accounted for.
2. The chart [1] in the linked original source ([2]) shows no error bars. The chart is trying to lead the reader to the conclusion that something new is happening. However, without error bars, there's no rational way to arrive at that conclusion.
