With 2019 on pace as one of the warmest years on record, a major new study from the University of California, Davis, reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming.
The study, published today in the journal Science Advances reports that the Arctic has warmed by 0.75 C in the last decade alone. By comparison, the Earth as a whole has warmed by nearly the same amount, 0.8 C, over the past 137 years.
“Many of the changes over the past decade are so dramatic they make you wonder what the next decade of warming will bring,” said lead author Eric Post, a UC Davis professor of climate change ecology. “If we haven’t already entered a new Arctic, we are certainly on the threshold.”
