DESCRIPTION:In this talk I will provide highlights of two different - but 
 overlapping - research topics. Both relate to the processes that drive sur
 face temperature variability\, and both have broad implications for unders
 tanding climate variability and change at high latitudes.\n\nIn the first 
 part I will focus on the role of ocean dynamics in driving sea-surface tem
 perature variability. The key conclusion is that ocean dynamics act - in t
 he net - to damp rather than drive low-frequency sea-surface temperature v
 ariability. The upshot is that observed decadal variability - including th
 at in the high latitude oceans - is due primarily to atmospheric processes
  and would be larger in the absence of ocean dynamics.\n\nIn the second pa
 rt I will focus on changes in temperature persistence under climate change
 \, again highlighting results over the mid-high latitudes. Here the key fi
 nding is that temperature persistence is certain to change across the glob
 e\, and that the signs of the changes depend critically on various physica
 l processes. Some of the largest changes are found over regions of sea-ice
 . I will argue that one key but overlooked process is the changes in surfa
 ce temperature damping timescales under climate change.
