Abstract: hristiansen and Ljungqvist have presented an extratropical NH temperature reconstruction using a method (LOC) that they claim ?preserves? low-frequency variability, at the expense of exaggerated high-frequency variability. ...

Abstract: The authors estimate the change in extreme winter weather events over Europe that is due to a long-term change in the North Atlantic Oscillation (NAO) such as that observed between the 1960s and 1990s. Using ensembles of ...

Abstract: AbstractSystematic comparisons of proxy-based reconstructions and climate model simulations of past millennium temperature variability offer insights into climate sensitivity and feedback mechanisms, besides allowing model ...

Abstract: Instrumental meteorological measurements from periods prior to the start of national weather services are designated “early instrumental data.” They have played an important role in climate research as they allow daily to ...
