the El Niño has something to do with what’s happening in the Arctic

Serreze agrees that the El Niño has something to do with what’s happening in the Arctic. “I think this is more than coincidence. That we have this very strong El Niño at the same time when we have this absurd Arctic warmth. But exactly what the details are on that, I don’t think we can say right now,” he says.

In Alaska, matters have been quite warm but not record-breaking this winter, says Rick Thoman, climate science and services manager for the National Weather Service in the state.
“It’s been another warm winter in Alaska,” Thoman says. “No other way to put it. This is the third in a row that’s been significantly warmer than normal.” Alaska’s winter so far (taking into account the months of November, December and January) has been the third warmest on record since 1925, he says.

Scientists are floored by what’s happening in the Arctic right now

So, if the present El Nino has something to do with what's happening in the Arctic then possibly all expectations we are used to worldwide regarding the weather are now no longer true. 

I would say we are in a "New Normal" but likely this "New Normal" will change to a progressively new New Normal every 5 or 10 years now.

So, it's possible that what winter, Summer, spring and fall have meant for thousands of years wherever we live will not necessarily mean that anymore.

 

For example, Castle Lake is an Alpine lake I have visited since I was 5 years old in 1953. The last 2 years were the first in my memory where it never froze once. But, this year the snow stayed on the lake and was 3 to 5 feet deep. But, there were no ice fishing holes visible so that means there wasn't thick enough ice under the snow to actually trust it.

So, my thought is we are now in a progression where likely I will never trust the lake ice enough to walk or ski on it ever again even in an El Nino year.
