Posts and Pseudo-Posts

Please click here and here and read the comments to a WUWT poster by A. Halperin (mainly the first one)

  • A couple of comments by Gianluca, a reader of, referred to the 97% consensus on AGW among (climate) scholars (Italian version). (see also the comments at, where Gianluca expressed his idea for the first time).
  • A comment to the 2018 IPCC Report on Climate (IPCC-SR1.5) by Zavatti & Mariani, October 2018; pdf (In Italian).
  • Why I'm a Skeptic (in italian, 37 pages, pdf);   Available also at: Climate Monitor
  • A list of Frank's papers on errors in GCMs
  • An Aerial Photograph of the northern coast line of Civitanova Marche (Central Italy). Good example of diffraction where plane wavefronts became spherical after a slit or an obstacle.
  • An exchange of mail with Ilya Serykh about the lunar influence on ENSO (18.6 yr period and its sub- and super-harmonics), April 2020.

  • Here, data for my posts and pseudo posts (DM, posts never written or never published) are archived and made available to Climate Monitor (CM) readers (and any other people interested to). This page is the support site for my posts at Climate Monitor.      • Posts by Franco Zavatti on CM

  • LR04stack.txt (1st millions year BP or 1 Ma). LR04.png, LR04.pdf (1st Million years)
  • R_Italia_secolari_CM_last.xls (Updated through October 2022). Monthly Precipitation of 27 century-long Italian stations

    For any of the following links

    Note 1: In MEM Spectra of monthly series, periods are in months so, if you want periods in years you must divide the period by 12; e.g. in Bongo
    xcol 1                (xcolumn -the period in my spectral output- is the 1st one in the dataset)
    xoper / 12        (divide by 12 the xcolumn. Note the needed space between / and 12)
    Note 2: When original dataset is organized as year month datum (e.g. 1975 1 0.56), I translate "year month" as decimal year=year + month/12 (e.g. 1975+1/12=1975.0833). This implies that December 1975 is 1976.0000 and the same for any December. Why do I use this transformation? Because I compute it AFTER I have information of the whole month, i.e. at the end of month (not at its half-length), so I do not use 1975+(1/12-0.5)=1975.4167.
