DESCRIPTION:Despite being remote to many of the major population centres o
 f the planet\, the polar regions are critical components of the Earth Syst
 em. They are central to the planetary-scale ocean circulation\, they stron
 gly govern and modulate our climate\, they are home to the last remaining 
 ice sheets\, and coupled processes here exert huge influence on global oce
 an productivity. The polar oceans are disproportionately threatened by cli
 mate change: they are warming rapidly\, sea ice is retreating\, and acidif
 ication is advancing strongly. These changes have potential to disrupt the
  marine ecosystem\, with consequences for food security and sustainable li
 velihoods\, both for local and Indigenous populations and beyond. Further 
 rapid transformations are predicted throughout this century\, though the s
 everity of their impacts will depend strongly on action taken now to mitig
 ate climate change. This talk will provide an overview of the changing pol
 ar regions and their importance to Planet Earth and its inhabitants\, draw
 ing on findings from recent and ongoing research programmes and assessment
 s\, including the recent IPCC Special Report on the Ocean and Cryosphere.
