How old is today? light comes from everywhere and from nowhere. The ocean, glittering then vanishing in gauzy vapors, handles us more gently than anyone could have hoped. Snow flurries in and hurries out. Mists veil coasts so raw, so … Continue reading
Results of short literature search on impacts of climate change upon ecosystems and bird or animal migration patterns, from the journals of the Ecological Society of America
I decided to do a quick literature search on the impacts of climate change upon ecosystems and migration patterns. I could have kept the list private, but why not make it public? Not all these articles are purely about the … Continue reading
I have been following, with keen interest, the post and comment thread pertaining to “Democratising science” at the blog I monitor daily, … and Then There’s Physics. I think the core subject being discussed is a little different from my … Continue reading
From the scientific journal Nature, a preview: “Finding Dory”, movie Director: Andrew Stanton Opens 17 June 2016 Digital-animation giant Pixar releases the much-anticipated follow-up to its 2003 “Finding Nemo”, a film so successful that clownfish are now often referred to … Continue reading
“A very short history of climate change research“, by Alice Bell. The story of scientists discovering climate change is longer than many of us tend to imagine. We’ve had a sense that what humans do might effect the climate since … Continue reading
It was the year 2000, Elizabeth Houghton had just died, and the plan was to restore the ecosystems about Fowl Meadow
Please remember Elizabeth Houghton as you pass by Routes 128 and 95 in Canton, looking north over her beloved Fowl Meadow and the Neponset River. She can no longer show you her photographs of the watershed under flood conditions and … Continue reading
The recent paper by Hansen, Soto, and others has caused a stir, as I suspect it was intended to do so. I posted about this paper earlier. Now Professor Hansen has responded to the critics of his team’s work and … Continue reading

Kevin Jones asked me if I could put the links in a Comment on a post I made at Google+ in a collection or something for reference. I am therefore repeating the Comment with these details below. No one simple … Continue reading
(Hat tip to Dan Satterfield.) A TED talk. Bacteria develop resistence so quickly that pharmaceutical companies have decided developing new ones is not in their best interest. From the speaker, Maryn McKenna.
Bill McKibben writes about the hope of domestic and home solar, and air-based heat pumps (*), in The New Yorker. I share that hope. Another good book on the same: Mark Schapiro’s Carbon Shock: A tale or risk and calculus … Continue reading

Destroying the Most Persistent Scientific Myth In America – Dan's Wild Wild Science Journal – AGU Blogosphere.
Carl Safina elaborates on the limits of exploitation. It’s consistent with what David Suzuki conveys in his succinct presentation, linked below: As Suzuki says, this isn’t politics or opinion, or even biology, it’s just math.
“Human activity has nothing big enough to affect Earth.” That’s disingenuous and, usually, the speaker knows better but is trying to dissuade an audience from thinking human activity does. Or they parrot someone who is trying to do that. But … Continue reading

I’m digging into the internals of ABC, for professional and scientific reasons. I’ve linked a great tutorial elsewhere, and argued that this framework, advanced by Wood, and Wilkinson (Robert), and Wilkinson (Darren), and Hartig and colleagues, and Robert and colleagues, … Continue reading
Professor Darren Wilkinson offers a pithy insight on how to go about constructing statistical models, notably hierarchical ones: “… we want to model the process as we would simulate it ….” This appears in his blog post One-way ANOVA with … Continue reading
Climate modelers and models see as their frontier the problem of dealing with spontaneous dynamics in systems such as atmosphere or ocean which are not directly forced by boundary conditions such as radiative forcing due to increased greenhouse gas (“GHG”) … Continue reading
illustrating particle filters and Bayesian fusion using successive location estimates on the unit circle
Introduction Modern treatments of Bayesian integration to obtain posterior densities often use some form of Markov Chain Monte Carlo (“MCMC”), typically Gibbs sampling. Gibbs works well with many Bayesian hierarchical models. The standard problem-solving situation with these is that a … Continue reading

There’s a report in the Financial Times today that UN negotiators are considering a proposal to phase out oil, coal, and gas by 2050. There’s a second permitting fossil fuels to be used, but only in countries which ensured “net … Continue reading
And, of course, I don’t eat land animals either. I will sometimes have scallops and clams.
From the University of Maine’s Climate Reanalyzer. Hat tip to Carl Safina.
“Home rule” means a lot of things. But, as the Catholic hierarchy in Rome once did, the educational authorities of Gilbert, Arizona, USA, are apparently taking it one step too far. Dan Satterfield reports that certain pages in a biology … Continue reading
Setting aside outright fabrications (1) such as those promulgated by the Representative Lamar Smith (R-Texas), laughingly selected as the Chair of the House Committee on Science, a common claim in the Comment sections at The Hill and elsewhere is that … Continue reading
