Arctic sea ice / Re: The 2019/2020 freezing season
« Last post by El Cid on Today at 07:49:54 AM »
The Chuckchi sea (and the Bering) can really start the next melt season with the record low volume (again). But it won't be a catastrophe because the CAB still have the pretty thick ice that will mostly survive the melt season.
This is wrong. The Chukchi and Bering are, IMO, directly tied to the freezing season in North America and its duration. If the Chukchi and Bering's volume remains at record lows through the freezing season and into the spring, there is a very good chance winter will not abate until May, or even June, across the most productive food-growing regions on the planet.

Well, let's test this theory. 2016,17,18 autumn ice cover was very low in the Chukchi/Bering region. So I decided to see how that changed next spring's (so: 2017,18,19) temperatures vs the baseline of 1950-80. This should see serious cold in the NA region if the theory was true. This is what I found (see below)
 April is really a bit colder than the "good ol' days" but May is not at all. Neither June.

There is some merit to this theory, as there seems to be some displacement of the Arctic cold pole into the Hudson region but I think it is exagarrated very much. Anyway, we shall see what this spring brings. I am open to new ideas and like this theory but do not find strong support for it in the data (yet?)

Define "lower care" perhaps ?

A huge expense as billed comes from end of life care in the USA. Other countries have more realistic views on where the money should be spent. If that is "lower care" i say lower away. I have seen far too many cases of US doctors overruled by family on keeping the poor sod alive with multiple tubes for multiple weeks in vegetative state with no benefit except to the US medical industry. And leaving the family with crushing debt.

Fuck that noise. I have experienced and witnessed medical care in several countries, as have many here, and when we tell you that the US medical system sucks,  we are speaking from experience.

But really, what we on the forum think is irrelevant. For this thread, what matters is if a public health care system like sanders is enuf to sink him as candidate. I doubt it.

Question: How can the CDW start to upwell if there is no surface wind increase?
...

It seems to me that your averaging is masking the signal that I am talking about, as the linked reference makes it very clear that the westerlies wind stress driving the Antarctic Circumpolar Current (ACC) has increased"… by almost 40% …" over the past 40 years. 
...

Thanks again, ASLR. From this paper it's clear that it's not the mean wind velocities that have increased much, but the shear surface stress from winds. This is mainly due to an increase in wind variability over those years. There are pretty big differences between the different reanalysis products though.

I attach another figure from that paper, showing wind stress trends, as well as eddy kinetic energy (EKE) trends over time that demonstrate these issues.

Ramen!


I was at a presentation last year where a number of journalists & former journalists laid out the facts about the numbers of their colleges who had been let go. Sad times for those who prefer a well written piece from knowledgeable sources.
