108 years of river ice break-up dates for the Tanana River at Nenana. This is one of the very best climate records in Alaska, with the date and time of break-up taken at the same place that's had little change in population, date recorded in the same funky way, Tanana River is undammed and in one channel at the place of measurement. The trend is obvious: a typical break-up nowadays is a bit over 8 days earlier than it was prior to the 1970s. #Climate#ClimateDiary#Alaska @Climatologist49
@AlaskaWx@Climatologist49 Interesting that there’s no major trend in green up dates (per your post the other day). That must be predominantly influenced by daylight hours?
