the “canary in the climate change coal mine”

• wine (see also Napa Valley)
• the boreal forests of Quebec
• Perth
• Australian ski resorts
• the Sahel
• polar bears
• trout
• Alaska (see also the Arctic, which has been subject to expert peer review)
• the Northeast (this would be US)
• mountains
• November
• Tuvalu
• Flamingo (the former Florida town, not the bird)
• the marine pelagic ecosystem
• the black guillemot

(Full disclosure: I’ve done it too: “Mountain ecosystems are a canary in the climate-change coal mine.”)
