Example predictions of climate impacts associated with the mid-1990s warming of the
high latitude North Atlantic. Observations (

period after the warming (1999-2009) minus the period before the warming (1970-1994), for (

temperature , (

were fi rst detrended to remove the slowly varying climate change signal.

land associated with the rapid warming of the high latitude North Atlantic during
the mid-1990s (Robson et al.
2012
,
2013
). For example, whilst not perfect, the pre-
dictions do indicate reduced rainfall during boreal summer over the United States
and Southern Europe and increased rainfall over the Sahel, Amazon and Northern
Europe (see Fig.
