Thwaites Glacier Research Explained: Watch the 70-Second Video
Watch our narrated Thwaites Glacier research explainer with NASA archive imagery, conceptual diagrams, captions and a transcript. Read the research context.
Video transcript
Thwaites Glacier is changing. But the latest research is not a countdown to instant collapse. The important discovery is where seawater can reach the ice.
Where grounded ice begins to float, tides can move seawater beneath a wider transition zone. Representing that process helps models reproduce the glacier’s observed retreat. This animation is a simplified explanation, not a measured cross section.
The study reports an upper contribution of about three centimetres, plus or minus six millimetres, by twenty one hundred, under its assumptions. That is from Thwaites alone. It is not total global sea level rise.
An early date in some simulations concerns detachment from a stabilizing ridge. It does not mean the whole glacier disappears that year. Your local flood exposure also depends on land movement, tides and regional ocean conditions.
Use official local flood information and alerts. Check access routes and shared building utilities. Read the full explanation and use the planning checklist in this article.
