Posted on 11/10/2020 by richard telford

It is about a year since my paper discussing the reproducibility of high resolution reconstructions was finally published, so I thought I should give a full account of what has happened since. Nothing. None of the authors of the papers … Continue reading →

Erroneous information … was given

Posted on 23/11/2019 by richard telford

By coincidence, days after I wrote about the apparently very low midge counts in Hiidenvesi, the authors published a correction. Erroneous information considering Chironomidae and Chaoboridae accumulation was given in Figure 4 published in Luoto et al. (2017). Therefore, it … Continue reading →

I wandered lonely as a cloud That floats on high o’er vales and hills, When all at once I saw a crowd, A host, of golden chironomids; Beside the lake, beneath the trees, Fluttering and dancing in the breeze. Continuous … Continue reading →

Count-less chironomids?

Posted on 01/09/2019 by richard telford

Most papers that present microfossil assemblages report (not always accurately) the minimum number of microfossils that were counted in each sample, an important indicator of the precision of the data. Some do not. For these papers, the reader should be … Continue reading →

Sunspots and raindrops

Posted on 19/02/2019 by richard telford

It is time, as the walrus said, to talk about another paper reporting an effect of solar variability on the Earth’s climate. Laurenz et al. (2019) correlate European country-scale precipitation data from CRU with the number of sunspots, a proxy … Continue reading →

Autocorrelation in the testate amoeba calibration set

Posted on 10/12/2018 by richard telford

Amesbury et al examine the autocorrelation in their huge calibration set. I thought I would do the same, increasing the resolution of the analysis to get a better handle on what is going on. This is an RNE plot. It … Continue reading →

Testing testate amoeba: some comments on Amesbury et al (2018)

Posted on 01/12/2018 by richard telford

Today, I have been reading and thinking about a new paper presenting a huge testate-amoeba calibration set for reconstructing water table depth in bogs (Amesbury et al 2018). This calibration set, with almost 2000 samples, is the synthesis of many … Continue reading →

No new data no comment at Nature Communications

Of all the modes of post-publication peer review, comments published in the same journal as the original article are the most visible, and because they have survived editorial and reviewer scrutiny, carry at least modicum of credibility. Unfortunately, comments are … Continue reading →

Chironomids are cunning wee beasties

Posted on 09/09/2018 by richard telford

Since I had examined almost every aspect of the data from the remarkable Lake Żabińskie chironomid-inferred August air temperature reconstruction, some time last summer I thought that I would, for completeness, have a quick look at the instrumental temperature data. … Continue reading →
