Global warming in northern Europe and the eastern US could be partially offset in future winters because of the sun entering a weaker cycle similar to the one which enabled frost fairs to take place on the river Thames in the 17th and 18th century, according to new research.
However, the study said any potential weakening in solar activity would have only a small effect on temperature rises at a worldwide level, delaying the warming caused by emissions from cars, factories and power plants by around two years.
