Another paper refutes the Mann made hockey stick – MWP was ≈1°C warmer than current temperatures

This new paper uses a rather unique proxy; high-resolution samples micromilled from archaeological shells of the European limpet, Patella vulgata. Mr. Limpet would be proud. A paper published this week in the journal Palaeogeography, Palaeoclimatology, Palaeoecology finds that the Medieval Warming Period “was warmer than the late 20th century by ~1°C.” The paper adds to…

Hump Day Hilarity: Bringing in the sieves

Science by Lucia, cartoon by Josh. Josh writes: Yesterday Lucia sent me an email about the recent Gergis et al ‘on hold’ paper with the subject title “Do you understand the math enough to do a cartoon?”. My response was, of course, to nervously read the email to gauge just how embarrassing my assured ‘fail’…

American Meteorological Society disappears withdraws Gergis et al paper on proxy temperature reconstruction after post peer review finds fatal flaws

UPDATE: It appears the paper has been withdrawn and credit acknowledgement given to Steve McIntyre, see below: There was yet another recent “hockey stick” being foisted on the public. Gergis et al. It says: The average reconstructed temperature anomaly in Australasia during A.D. 1238–1267, the warmest 30-year pre-instrumental period, is 0.09°C (±0.19°C) below 1961–1990 levels.…

The 1000 year Australian hockey itch

From the University of Melbourne, I’m sure Julia and Flannery are thrilled at this paleo-reconstruction, and of course, the blame goes on Mann, er man. I find it interesting though that the lead author, Dr Joelle Gergis, thinks of her science work as a “guerrilla war”. From “Science Matters”: Seems like just another angry Michael…

Josh on McIntyre's rebuttal of Mann's book

As I reported in McIntyre’s rebuttal of Michael Mann’s pants-on-fire book,  Steve McIntyre came out of hiatus yesterday to pen his rebuttal to Mike Mann’s book, seen below. The points Steve made were well, inspiring, to Josh. For example: Instead of “forgetting”, as any prudent person would have done, Mann brazenly repeated his earlier lie to…
