New paper finds Ireland climate controlled by natural ocean oscillations and Sun over past 5000 years
A new paper published in Palaeogeography, Palaeoclimatology, Palaeoecology reconstructs the climate of Ireland during the past 5000 years and finds "Some terrestrial palaeo-climatic changes in Ireland appear to coincide with changes in the North Atlantic [Oscillation or NAO] and solar activity." The authors show reconstructed solar activity has increased over the past 500 years to some of the highest levels of the past 5000 years, and correlation with some warming periods. Reconstructed CO2 levels, however, do not show any apparent correlation with temperature or precipitation during any portion of the past 5000 years.
