On the Cusp Indicators?

Alaska have been setting some cold temperature records and the sea ice is recovering at a rapid rate, after plunging to a record low, and now the Hudson Bay ice is growing more rapidly than in the past five years.  See the charts below.

Rick’s musings about happenings with Alaska’s weather and climate writes:

Here’s an update of daily temperature anomalies for Fairbanks through Sunday. At the top is a plot of the actual daily mean temperatures. The gray shading represents one standard deviation from the 1981-2010 normal, so temperatures outside of the shading are “unusually” warm/cold for the date.

It as colder than normal in January and at the start of December. Is this a sign of what is to come. According to geologist it only took a generation go from warm to very cold. Are we on the cusp of that change?

    It’s good news but I fear that Svalbard is one of the key indicators of summer ice loss. I suspect that the longer it takes for the ice to form around it in winter, the weaker the summer ice will be. Alternatively it may be that ice starts to recover at the Alaska end of the Arctic and the Svalbard end will be the last to recover. Who knows?
