Nov. 2 (Tuesday): Ice Sheets and SLR I<\/strong><\/span><\/h2>\n

10:00\u00a0 Why \u201cCommitted\u201d SLR? A Science-Youth Dialogue<\/strong><\/p>\n

\u201cCommitted\u201d sea-level rise occurs when the world\u2019s great ice sheets of Greenland and especially, Antarctica pass certain temperature thresholds, after which ice loss cannot be stopped but may take several centuries to actually occur.\u00a0 .\u00a0 These thresholds may be passed as early as 2030 given current emissions; or in the case of the West Antarctic Ice Sheet, may already have occurred due to today\u2019s 1.2\u00b0C of warming, What ate the inter-generational justice implications of this science?<\/p>\n

Organized by the University of Bristol and NSIDC. \u00a0Speakers: Twila Moon, Jonathan Bamber, two Youth (Divya from India and Amy from the U.S.)<\/em><\/p>\n

11:30\u00a0 Greenland\u2019s Tipping Point<\/strong><\/p>\n

Greenland\u2019s ice is 3 km thick, and runs entirely to its bedrock base which is currently below sea level.\u00a0 What is the tipping point of Greenland, where the altitude of the ice sheet is so lowered by surface melt that near-complete loss is unavoidable?\u00a0 An explanation of this important and complex ice sheet.<\/p>\n

Organized by NSIDC and GEUS. \u00a0Speakers: Jason Box and Twila Moon<\/em><\/p>\n

13:00\u00a0 Antarctica and Paris Goals: Risks of Massive Sea-level Rise<\/strong><\/p>\n

Recent published research shows the danger of massive, potentially irreversible, global sea-level rise within the next couple of centuries should temperatures overshoot 2\u00b0C. Perhaps most sobering, this loss may become rapid and permanent, with no halt in ice loss even should CO2 concentrations return t pre-industrial levels; and rates approaching 5 cm\/year by 2150, and 10 meters of sea-level rise by 2300 should today\u2019s emissions levels continue.\u00a0 IPCC scientists provide a clear-eyed look at risks from Antarctica, and implications for the Paris Agreement temperature goals.<\/p>\n

Organized by the University of Massachusetts-Amherst. \u00a0Speaker: Rob DeConto<\/em><\/p>\n

14:30\u00a0 Important Role of Ice Shelves<\/strong><\/p>\n

Ice shelves play a key role in stabilizing ice sheets; especially on Antarctica.\u00a0 We have seen rapid ice loss occur on both Greenland and the Antarctic Peninsula when glaciers lose their supportive or \u201cbuttressing\u201d ice shelves; and once lost, it appears difficult for them to grow back.\u00a0 Why is this the case, and why is this so important for Paris temperature goals?<\/p>\n

Organized by\u00a0the University of Massachusetts-Amherst and NSIDC. \u00a0Speakers: Shaina Sadai and Twila Moon<\/em><\/p>\n

16:00\u00a0 Why is West Antarctica So Important to Near-term Sea-Level Rise?<\/strong><\/p>\n

The geography of the West Antarctic Ice Sheet holds the key as to why this part of the continent may be subject to rapid collapse, leading to sea-level rise of several meters per century at higher temperatures.<\/p>\n

Organized by the University of Bristol. \u00a0Speaker: Jonathan Bamber and Rob DeConto<\/em><\/p>\n

18:00\u00a0 Antarctica and the Limits of Adaptation<\/strong><\/p>\n

Antarctica holds nearly 70 meters of sea-level rise, and may be subject to thresholds where its ice sheet loses mass for many thousands of years.\u00a0 A discussion between cryosphere scientists and people from low-lying nations on the limits of adaptation and need for preventive mitigation.<\/p>\n

Organized by the University of Bristol, University of Massachusetts-Amherst and Climate Central. \u00a0Speakers: Jonathan Bamber, Rob DeConto and Benjamin Strauss (Possible opening by Chilean Minister of Science Andr\u00e9s Couve)<\/em><\/p>\n

19:30\u00a0 Cryosphere C\u00e8lidh: Global South and Cryosphere: Facing the Crisis<\/strong><\/p>\n

Cryosphere changes caused by global warming actually have their greatest impacts, in terms of scale and population in the Global South.\u00a0 \u201cFacing the Crisis\u201d comprises a multi-media exhibit of photography, artwork, videos and other media produced by people of the Global South themselves, showing impacts of cryoshere dynamics such as sea.level rise from ice sheet and glacier melt; as well as work on mitigation and adaptation.<\/p>\n
