well, they predicted a ridiculously cold winter this year and got it right. the mainstream forecasts were in the same neighbourhood, but not as extreme. for example, they predicted it would be cold in the upper midwest but warm in the southern midwest (it has been cold in both places) and cold in ontario but warm on the coast (it has been cold in both places).

meaning that it probably comes down to a variable or two and that, for whatever reason, the almanac was able to predict that the arctic air masses would overpower the probably maritime factors that the mainstream forecasts thought would overpower the arctic air masses.

it would be really nice to actually see how they came to that conclusion, but they won't publish.

i mean, it's easy to write it off as pseudo-science, but the truth is that we can't analyze the method because it's not public. sure, that obviously justifies some healthy skepticism. but it seems foolish to write something off without even knowing what it is.

the last question is sort of silly, though. it's widely acknowledged that sunspots and planetary position have an effect. the problem is that the argument often comes up in the context of people arguing against anthropogenic climate change - and the overwhelming evidence that sunspot activity isn't even correlated with the increases in temperatures we've seen. but denying a link between climate change and sunspots doesn't negate the sun's effect on the earth's weather (weather, here, being contrasted with climate). we can connect all kinds of weather phenomena to sunspots. and with positioning, this is a real thing that's widely accepted: http://en.wikipedia.org/wiki/Milankovitch_cycles

but if they won't publish, there's no way to scrutinize what they're doing. from where you or i are standing, it's as good as magic. but if we knew what they were doing, we might be able to pull something of value out of it.

it's been widely published in wonky sources (and less wonky sources) that sunspot activity recently slowed down to almost nothing, leading up to a magnetic pole reversal that finally happened (after a longer than expected wait) a few days ago. even though the source of the cold is arctic air moving south, you don't have to take an obscure, gw-denying position to acknowledge that that might have had an effect on the cold winter we've had.

it would just be nice to see their calculations opened up so that that could be examined.

the recent magnetic reversal dismisses the fears in the article, but it gets to the point i'm making:

right. but it could give us a nasty winter or two.

then again, the current "nasty winter" would have been normal 30 years ago.

btw, an interesting question that i've explored a little on this page going way back is whether there may be a way to connect volcanic activity to "space weather". i'm mostly thinking in terms of gravity. there's a really intuitive example with tides being caused by the moon. could all the gravity floating around us, from the sun and jupiter and whatever else, have an effect on the way continents interact, thereby affecting volcanic activity? if so, there's not a contradiction in the two ideas.
