How can we tell temperatures from thousands of years ago?
Sher-Rine Kong has been studying a lake in Svalbard, and her research suggest that temperatures during the Early Holocene - around 11,700 years ago - were up to 3.5 °C warmer than today.

How will a sudden change in the function of the ocean circulations impact Iceland, Europe, and the world?
We had a great panel at the Arctic Circle Assembly 🌊🧪
It was a scientific discussion on the likelihood, uncertainties, and possible consequences if the large ocean circulation were to shift.
