It is hardly surprising that European rural station temperatures are correlated with N Atlantic SSTs. I read somewhere that the top 400 meters of the oceans contain more variable enthalpy than all the atmosphere, by more than three orders of magnitude.[Below 400 meters, the water is at 4 degC, its maximum density] i.e Atmospheric temperature averages are slaved to SSTS. This is bad news for Europe, with the N Atlantic cooling rather dramatically in the last six months. I still maintain that any drop in Atlantic temp is not directly the cause of dramatic reductions on land. When N Europe gets REALLY cold, it's due to northern or easterly winds. If the mild westerlies drop by 5°c, that were probably at 10°c anyway, they're just too warm to get down to freezing conditions. I think rather cooling Atlantic may upset the weather patterns which may perhaps be seen in NAO. The westerly patterns reduces, which opens the back door via blocking. Of course, if the Atlantic drops 10°c were screwed, but perhaps such a drop is unlikely?? Haven't you heard? You're already screwed as decreed by GoreAl & crew.

Droughts in the Czech Lands, 1090–2012 AD
R. Brazdil ´et al. www.clim-past.net/9/1985/2013/cp-9-1985-2013.pdfFound this Twitter Adapt 2030 This is for you Dresi. Perhaps you've already seen it ... but I don't remember it posted here. Same first author I think as another you posted not so long ago. Abstract. This paper addresses droughts in the Czech Lands in the 1090–2012 AD period, basing its findings on documentary evidence and instrumental records. Various documentary sources were employed for the selection of drought events, which were then interpreted at a monthly level. While the data on droughts before 1500 AD are scarce, the analysis concentrated mainly on droughts after this time. A dry year in 1501–1804 period (i.e. pre-instrumental times) was defined as a calendar year in the course of which dry patterns occurred on at least two consecutive months. Using this definition, 129 dry years were identified (an average of one drought per 2.4 yr). From the 16th to the 18th centuries these figures become 41, 36 and 49 yr respectively, with the prevailing occurrence of dry months from April to September (73.7 %). Drought indices – SPEI-1, Z-index and PDSI – calculated for the Czech Lands for April–September describe drought patterns between 1805 and 2012 (the instrumental period).

You win the 2018 Climate Data Award Fred. Bunkum and balderdash have finally been "gored". A well deserved, self inflicted wound.

Fred, I've posted that reference in other places with this lead: It has long been my contention from looking at BoM data that - away from the centres of population - there has been little or no mean temperature rise. A cursory glance thru this Iowa website article seems to support that view. Looking globally, this may be a game changer. WDYT?
It may pique the interest of one Dr. Bill Johnston who has been dissecting Australian temperature records.

[Snip ] Y'all still have temperature stations in the "out back"? Too right, cobber. The outback is awash with them, although none is used in BoM data.

Even though it only accounts for a minuscule fraction of total solar radiation, the impact of solar UV, EUV and X-ray radiation on the Earth's upper atmosphere is profound. Solar UV flux is a major driver of stratospheric chemistry, and increases in ionizing radiation significantly affect ionosphere-influenced temperature and electrical conductivity.
