Abstract abstracts
So I am searching through the Web of Science for papers reporting 11 yr (Schwabe) cycles in palaeoproxy data (especially tree-rings) when I find this title, which looks promising: LUNI-SOLAR 18.6-YEAR AND SOLAR-CYCLE 10-11-YEAR SIGNALS IN CHINESE DRYNESS WETNESS INDEXES … Continue reading
Are Tibetan chironomids mesmerised by solar variability?
It’s been a while since I examined a paper that purports to present palaeoecological evidence for a climate response to solar variability. But last night, flicking through the recently published papers in Quaternary Science Reviews, I came across Zhang et … Continue reading

You cannot smooth your way to significance
Imagine you have three 73-year long instrumental climate records that you want to correlate with solar activity in the last century. The instrumental records are noisy so you smooth them with a five-year moving average, and then you note that … Continue reading
Incidence of papers reporting spurious correlations with solar variability correlates with solar variability
From the price of wheat (Hersche 1801) to childhood mortality (Skjærvø et al 2015), there seems to be no end to papers reporting spurious correlations with solar variability. As both these examples are published at solar maxima (±5.5 years), I … Continue reading
Is there robust evidence of solar variability in palaeoclimate proxy data?
This is my EGU 2015 poster which I am presenting this evening. Poster B25 if any readers are at EGU and want to see it nailed to the board. With my coauthors Kira Rehfeld and Scott St George, I have done a … Continue reading

Questions for Yan et al (2015), Willie Soon’s new paper
Willie Soon and Bob Carter are coauthors on a new paper in Nature Geosciences by Yan et al. It looks like an interesting paper exploring the movements of the intertropical convergence zone between China and Australia over the last millennium … Continue reading

Did the floating bog quiver in the sunshine?
The current edition of The Holocene has a paper by Xu et al that reports a relationship between solar activity and millennial-scale failures of the Indian Summer Monsoon as recorded in peat deposits of Lake Xihu, southwestern China. Is this robust evidence … Continue reading

Sunspots and survival in Norway
Back in January, I expressed my doubt about Skjærvø et al (2015) who reported that children born during solar minima had a higher probability of surviving to adulthood, had higher fertility and higher lifetime reproductive success. Skjærvø et al (2015) argued that this was a … Continue reading
Willie Soon at Heartland: “The sun is big”
Dr Willie Soon is in the news again. His recent paper with Monckton et al ended with the conflict of interest statement The authors declare that they have no conflict of interest. A statement seeming at odds with his long … Continue reading

Solar science Heartland style
[I wrote this some time back, but got distracted by Lord Monckton’s inability to use a scroll bar, and then lost momentum. Given Willie Soon’s return to media attention, I thought I should give his presentation a little loving, but … Continue reading
