Wintertime extreme events recorded by lake sediments in Arctic Norway ...
New time series of long-term hydroclimate variability in the Arctic are urgently needed in order to better understand the response patterns to external forcing and changes in boundary conditions for global climate models. Here, we present a high-resolution record of mass-wasting events based on anal...

New time series of long-term hydroclimate variability in the Arctic are urgently needed in order to better understand the response patterns to external forcing and changes in boundary conditions for global climate models.
