Application of a novel nonlinear filtering technique to time series of daily temperatures in 48 meteorological stations from Europe yields the "lifetime" (akin to "correlation time") of temperature curves. This lifetime displays sharp primary and lesser secondary maxima at the times of extrema in sunspot number. A phase shift occurs around 1960, when primary maxima of temperature lifetimes shift from sunspot maxima to minima. This may correspond to a major change in state of the solar engine. Although the worldwide validity of these observations remains to be demonstrated, these strong correlations emphasise the role of the Sun as the forcing factor of a significant part of the global temperature signal.
