Meltdown: The Scoop on Glaciers (Part 1)
Bibliographic record
Abstract
Glaciers and ice sheets play an important role in the global environment. They are storage systems of most of the world's fresh water, dramatically alter the landscape and sea level, affect ecosystems and provide us with unique records of climate and atmospheric conditions that go back hundreds of thousands of years. Global climate change has caused widespread accelerated glacier retreat, which has negative effects on fresh water availability, causes global sea level rise and affects climate and ecosystems at the local and global scales. In order to understand how glaciers affect life on earth, it is important to understand how glaciers work and what causes them to change. By being informed about natural systems such as glaciers we can understand why some changes in nature happen fast while others take longer, and why snapshots do not always reflect the big picture. This presentation will address recent measurements and predictions of glacier shrinkage and sea level rise, as well as local and global effects thereof, and will explain more complex issues such as 'Why have a handful of glaciers advanced in recent years and why does this not contradict records of global warming?'Speaker: Hester Jiskoot PhDDr Hester Jiskoot is Associate Professor of Physical Geography at the University of Lethbridge and holds a BSc and MSc in Physical Geography (University of Amsterdam, NL) and a PhD in Glaciology (University of Leeds, UK). She is an award winning NSERC-funded glaciologist, is one of the world experts on glacier surging and has published widely. Her main research interests are in ice flow dynamics, glacier-environment and glacier-climate interactions. Since 1991, Dr Jiskoot has been a member and leader of glaciological expedition teams, and has been on glaciers in Greenland, Svalbard (Spitsbergen), Iceland, the Yukon Territory, Alaska, the European Alps, the Canadian Rockies, and the Himalayas.In 2005 Dr Jiskoot was invited by the Canadian Standing Senate Committee on Energy, the Environment and Natural Resources, to advise about the role of glaciers in the water supply prognosis for western Canada. In 2009 she was elected Fellow of the Royal Canadian Geographical Society and in 2010 she became Associate Editor of the scientific journal Arctic, Antarctic & Alpine Research.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
