• Glacier retreat across the Tongass and Glacier Bay region is rapid and visible at human timescales; the calving glaciers of Glacier Bay have retreated 65+ miles since the late 18th century, with the pace accelerating since the 1970s.
• Yellow cedar dieback is the headline climate-attributed forest mortality story here: reduced snow insulation exposes shallow roots to spring freeze damage, killing the species across hundreds of thousands of acres.
• Garden-relevant: Sitka spruce, salmonberry, and Pacific crab apple are well-positioned for a warming PNW; their cold-hardy provenances are valuable seed sources for restoration further south.
