Re this and the blocking thread I am told that at the recent EGU AGU
Mojib Latif ascribed the recent warmth in western Europe to an
increase in the Meridional Overturning Circulation MOC (ie ocean heat
transport in the Atlantic), presumably in this talk-

apparently GCM forecasts have not handled it well. Presumably this
enhances the warm ocean/cold land regime and may enhance the length
and intensity of the spring blocking, as well as increasing the
sensible heat flux (for winter storms).
Another group has proposed that the waning of 'global dimming' (by
aerosols) is taking effect,
