TT32A:
Science of a Rapidly Changing Arctic System


Submit an Abstract to this Session


Session ID#: 48915

Session Description:
The Arctic system is changing rapidly. Melting land and sea ice, thawing permafrost, atmospheric extremes, warming oceans, and terrestrial landscape changes have already created a new Arctic “normal”. Dramatic future changes are expected, with significant consequences, ranging from sea level rise to ecosystem disruption, exacerbated greenhouse gas emissions to changing weather patterns. Based on an NSF Arctic System Science Workshop (April 2018) - gathering international scientists with expertise including land ice, sea ice, atmosphere, ocean, and terrestrial processes - this tutorial will overview the connected physical systems of the Arctic, discuss its recent evolution as the most rapidly warming region on the planet, and highlight the next frontier in Arctic system science. The future of Arctic system science includes developing new partnerships across observational and modeling efforts, focusing on interdisciplinary boundary regions between Arctic system components, exploring the feedbacks of increasingly common extreme events, and preparing research to understand the impacts of moving from an ice-dominated system to a water-dominated system. We need all hands on-deck to understand the consequences of warming across this difficult-to-study region. This tutorial will bring scientists, stakeholders, and the interested public up to date on Arctic system science and the challenges and opportunities ahead.
