William Connolley, aka the wiki warrior of climate, runs a blog called “Stoat” under the National Geographic brand. In his latest episode rant, he is complaining about his personal perception of Dr. Judith Curry’s professionalism regarding her ocean acidification discussion.
Is is just me, or does professionalism and f-bombs not go together? Sheesh.
Here is the screencap:
Both he and “Eli” (Chemist Dr. Joshua Halpern of Howard University) seem to have trouble with their own self images when it comes to professionalism.
All this over a change in pH from 8.25 to 8.14 (values given is Stoats rant). This is a small amount of variance which may very well be within the bounds of natural variability.
Maybe the Stoat never read this article from Jo Nova about a paper from Scripps on ocean pH:
It turns out that far from being a stable pH, spots all over the world are constantly changing. One spot in the ocean varied by an astonishing 1.4 pH units regularly.
The authors draw two conclusions: (1) most non-open ocean sites vary a lot, and (2) and some spots vary so much they reach the “extreme” pH’s forecast for the doomsday future scenarios on a daily (a daily!) basis.
Even the more stable and vast open ocean is not a fixed pH all year round. Hofmann writes that “Open-water areas (in the Southern Ocean) experience a strong seasonal shift in seawater pH (~0.3–0.5 units) between austral summer and winter.”
This paper is such a game changer, they talk about rewriting the null hypothesis:
“This natural variability has prompted the suggestion that “an appropriate null hypothesis may be, until evidence is obtained to the contrary, that major biogeochemical processes in the oceans other than calcification will not be fundamentally different under future higher CO2/lower pH conditions””
