A Baptist leader’s dream is being extinguished

Even Nobel Laureates can make a mistake needing correction

Edward J. Calabrese. Muller’s Nobel Prize data: Getting the dose wrong and its significanceEnvironmental Research 176 (2019) 108528

This paper evaluates the significant historical paper of Muller and Mott-Smith (1930), which successfully disputed the proposal of Olson and Lewis (1928) that background ionizing radiation is the driving mechanism of evolution. While the present analysis supports the general conclusion that background radiation is not a quantifiable factor affecting evolution, the paper reveals methodological errors and questionable conclusions in the Muller and Mott-Smith (1930) paper, which may have impacted the acceptance of the linear non-threshold (LNT) model. Most importantly, this paper reveals that in Muller’s (1927) Nobel Prize research he used a treatment exposure (total dose) that was 95 million-fold greater than the average background exposure, a value far greater than the 200,000 fold reported by Muller and Mott-Smith (1930). Such a large exposure rate dis- crepancy may be historically important as it may have led to the over-reliance on Muller’s research in support of the derivation and use of the LNT single-hit model.

Early season hurricanes in decline (slightly)

“Results show that despite 150+ years of global warming the frequency of early season hurricanes has actually declined by a small (but probably insignificant) amount, as evidenced by the dashed blue least-squares trend line. Certainly there is no clear evidence to support the author’s claim that they’re becoming more common.” click here

“if you hate our country, if you are not happy here…”

“As far as I’m concerned, if you hate our country, if you’re not happy here, you can leave,” Trump said this week at the White House. “… If you’re complaining all the time, very simply you can leave, you can leave right now. Come back if you want, don’t come back, that’s okay too. But if you’re not happy, you can leave.” click here

Antarctic sea ice declining — cause unknown

Claire L. Parkinson. A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the rates seen in the Arctic, Proc Natl Acad Sci, https://doi.org/10.1073/pnas.1906556116

A newly completed 40-y record of satellite observations is used to quantify changes in Antarctic sea ice coverage since the late 1970s. Sea ice spreads over vast areas and has major impacts on the rest of the climate system, reflecting solar radiation and restricting ocean/atmosphere exchanges. The satellite record reveals that a gradual, decades-long overall increase in Antarctic sea ice extents reversed in 2014, with subsequent rates of decrease in 2014–2017 far exceeding the more widely publicized decay rates experienced in the Arctic. The rapid decreases reduced the Antarctic sea ice extents to their lowest values in the 40-y record, both on a yearly average basis (record low in 2017) and on a monthly basis (record low in February 2017).
