As I’ve done for<\/a> a<\/a> few<\/a> years<\/a>, here is the updated graph for the Nenana Ice Classic<\/a> competition, which tracks the break up of ice on the Tanana River near Nenana in Alaska. It is now a 101-year time series tracking the winter\/spring conditions in that part of Alaska, and shows clearly the long term trend towards earlier break up, and overall warming. <\/p>\n

<\/a><\/center><\/p>\n

2017 was almost exactly on trend – roughly one week earlier than the average break up date a century ago. There was a short NPR piece<\/a> on the significance again this week, but most of the commentary from last year and earlier is of course still valid. <\/p>\n

My shadow bet on whether any climate contrarian site will mention this dataset remains in play (none have since 2013 which was an record late year). <\/p>\n\n<\/div> ","protected":false},"excerpt":{"rendered":"
