A new study by Cardiff's Dr Paola Moffa-Sanchez and colleagues (including Dr Andres Born, at the University of Bern, in Germany; Prof Ian Hall and Dr Stephen Barker, in Cardiff's School of Earth & Ocean Sciences; and Dr David Thornalley at University College London, formerly of Cardiff) finds that changes in solar activity can have a considerable impact on ocean-atmospheric dynamics in the North Atlantic, with potential effects on regional climate.
The authors examined seafloor sediments to determine how the temperature of the North Atlantic and its localised atmospheric circulation changed over the past 1000 years. Warm surface waters flowing across the North Atlantic, an extension of the Gulf Stream, and warm westerly winds are responsible for the relatively mild climate of Europe, especially in winter. Slight changes in the transport of heat associated with these systems can led to regional climate variability. This study's findings match historic accounts the notoriously severe winters of the sixtheenth and eighteenth centuries, predating global industrialisation.
Predictions suggest a prolonged period of low sun activity over the next few decades, but any associated natural temperature changes will be much smaller than those created by human carbon dioxide emissions.
