Reconstructed centennial variability of Late Holocene storminess from Cors Fochno, Wales, UK
ABSTRACT Future anthropogenic climate forcing is forecast to increase storm intensity and frequency over Northern Europe, due to a northward shift of the storm tracks, and a positive North Atlantic Oscillation. However understanding the significance of such a change is difficult because the natural...
