## The story

"Everyone is waiting for snow."

The model had already frozen the sea.

In 2019 the model froze the sea early. The coast froze late.

The paper publishes the direction and no magnitude. This drawing does the same. The two marks sit inside a declared break, so the space between them carries no value.

"It has rained so much that the roads are falling apart and we may have broken a temperature record. Everyone is waiting for snow. The bowhead whales are not close to Barrow yet either."

Over 12,000 observations, more than 1,500 km of coast.

Observers document sea ice, ocean conditions, weather, fish and marine wildlife, and unusual or extreme events. The program and the one before it have run since 2006.

which made hunting especially difficult.

Observers reported late freeze-up, warm conditions and stormy weather

The fall hunt took one whale.

Historical fall harvests have reached up to about 30. Spring is a separate season and is not in this count.

Most of the time the two records agree.

The paper reports the model generally captured the timing of seasonal changes, especially the end of the open water season. That is what makes one wrong season worth finding.

Ten authors. The observers are among them.

The paper says Indigenous observers are co-authors and shape its research questions, the interpretation of results and the priorities for model development. It argues Indigenous Knowledge can identify model deficiencies that conventional metrics miss.

A model can be broadly right and still wrong about the season you live in.
