SUMMARY:The long-term legacy of delayed climate mitigation on global glaci
 er change - Fabien Maussion\, University of Innsbruck

DESCRIPTION:Mountain glaciers have a delayed response to climate change an
 d are expected to continue to melt long after greenhouse gas emissions hav
 e stopped\, with consequences both for sea-level rise and water resources.
  In this contribution\, we use the Open Global Glacier Model (OGGM) to com
 pute global glacier volume and runoff changes until the year 2300 under a 
 suite of stylized greenhouse gas emission scenarios. We show that even und
 er scenarios that achieve the Paris Agreement goal of holding global-mean 
 temperature below 2 °C\, glacier contribution to sea-level rise will cont
 inue well beyond 2100. We also discuss the impact of early climate mitigat
 ion on regional glacier change and the consequences for glacier runoff\, b
 oth short-term (where some basins are expected to experience an increase o
 f glacier runoff) and long-term (where all regions are expecting a net-zer
 o or even negative glacier contribution to total runoff)\, underlining the
  importance of mountain glaciers for regional water availability at all ti
 mescales.
