Climate specialist with ACCAP/IARC at UAF, highlighting Alaska climate, environment & Indigenous cultures. Opinions are my own. I've been fascinated by #Arctic & #boreal #weather, #climate and #cultures for more than 50 years. I've worked as a weather & climate professional in private, public & academic spheres. I've been fortunate to live most of my life in Lower Tanana #Dene country near Fairbanks, #Alaska. Also, I have a big interest in Alaska Indigenous languages.

Arctic 12-month running temperatures as the difference from the 1951-80 average, updated through April 2024. The 10-year smoothed average shows the long term trend, the 2-year average captures some of the short term variability. OISSTv2.1 courtesy of NOAA/PSL/ESRL

A sure sign that contemporary 30-year climate normals are not keeping up with the rate of Arctic change: only one year (2021) since the early 1990s has less than half of land area in the Arctic (north of 60ºN) had annual average temperature above “normal", and eight years more than 90 percent of Arctic Lands were warmer than “normal". In an unchanging climate, this would bounce around 50% each year.

If you’re in Fairbanks, come by UAF for the Research Open House Thursday evening 4-7pm AKDT. I’ll be staffing a table in the Akasofu Building lobby, so stop by and let’s talk climate!

Sea ice extent in the Bering Sea remains close to 1991-2020 median in NSIDC data. Large areas of open water north of the ice edge are normal this time of year. The lack of any significant areas of lower concentration ice in the southern Chukchi Sea is unusual for this point in the Spring.

Sea surface temperatures departures from the 1991-2020 average around Alaska for the week ending May 10, 2024. Northern Bering Sea mostly below normal and partially sea ice influenced. Eastern Gulf of Alaska warmer than average. Data from OISSTv2.1 courtesy of NOAA/PSL/ESRL.

About a two mile strip of shorefast sea ice hanging on at Nome Saturday late afternoon. Beyond that open water, just visible as a thin dark blue line on the Nome CVB webcam looking across Front Street to Norton Sound beyond. 5pm weather 35F (+1.7C), slight sea breeze.

Western Alaska had another high precipitation early spring this year, making six out of the past seven March-Aprils with high end precipitation. I've got a Alaska and Arctic Climate Newsletter posted that investigates "is this just random variation or is something different."

Ice on the Kuskokwim River at Bethel, Alaska moved enough to carry the tripod downriver and trip the clock at 840am Wednesday May 8. This is ten days earlier than last year and very close to the modern average date of break-up, but is almost a week earlier than the pre-1990 average.

South Fox Sunday 1100am: party sunny, slight breeze, 49F (9.4). Close but not quite green-up.

And there it is: green-up on West Chena Ridge in Fairbanks, four days earlier than the 50 year median, and first "earlier than median" green-up since 2019.

Sea surface temperature departures from 1991-2020 normal in the high resolution OISSTv2 data from NOAA/PSL/ESRL. Eastern Gulf of Alaska remains warmer than normal, while sea ice influenced areas in the Bering Sea are cooler than normal.

The sea ice melt season in the Arctic is underway and I've got a review of April conditions in a new Alaska and Arctic Climate Newsletter.

Break-up on the Yukon River at Dawson, YT occurred on on the afternoon of April 28. This was the fourth earliest break-up since 1896: only 1940, 2016 and 2019 were earlier. Typical break-up nowdays is more than a week earlier than it was in the early to mid 20th century. @Climatologist49 @evaholland

It's almost time for the ACCAP/OneTree Alaska annual green-up webinar. 11am AKDT today (Tuesday). Free registration at the link, and it's also recorded and posted online afterwards.

So how do we get this kind of info out to people in those rural communities, and have them believe it over Fox/NewsMax/etc? https://mastodon.online/@parismarx/112351985490546456

@Scatterseed @mivox Call me crazy, but I occasionally think about all the organizations I donate large sums of money to if Ed McMahon ever calls to tell me I’ve won the Publishers Clearinghouse Sweepstakes.

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.

Winter snowpack meltout for Fairbanks was April 22: this was the last day with an inch or more snow on the ground based on the NWS observations. Meltout was ten days earlier than last Spring and almost exactly the long term normal. There is no long term trend. @Climatologist49 @CarrieinFbx @leepetersen @anisian

Green-up in Fairbanks is approaching. Using observed temperatures since March 1st and the forecasts for the ten days, our little model now showing a 60 percent of green-up late next week. The long term average green-up is May 8 and this year is sure to be earlier than that. @CarrieinFbx @anisian @mivox @themattphelps @debmcqueen @leepetersen @dboo @Climatologist49
