(Edits to repair smudges, 2020-06-28, about 0945 EDT. Closing comment, 2020-06-30, 1450 EDT.) There are lots of ways of learning about mathematical constructs, even about actual machines. One way is to push them into a place of improbable application, asking … Continue reading
via Code for causal inference: Interested in astronomical applications From Professor Ewan Cameron at his Another Astrostatistics Blog.
(Slightly amended with code and data link, 12th January 2019.) Prediction of electrical load demand or, in other words, electrical energy consumption is important for the proper operation of electrical grids, at all scales. RTOs and ISOs forecast demand based … Continue reading
Done by the Virginia Institute of Marine Science, new sea-level report cards offer a look at current sea-level rise rates, and projections. What’s interesting to me is making the projections conditional upon the character of the model used to project. … Continue reading
(Revised and updated Monday, 24th October 2016.) Weapons of Math Destruction, Cathy O’Neil, published by Crown Random House, 2016. This is a thoughtful and very approachable introduction and review to the societal and personal consequences of data mining, data science, … Continue reading

Yo, everyone! The final version of my book now exists, and I have exactly one copy! Here’s my editor, Amanda Cook, holding it yesterday when we met for beers: Here’s my son holding it: He’s offered…
This is a video and link from The Rocky Mountain Institute about New York State’s Reforming the Energy Visions or “REV”. I have written about REV before.
Yeah, how about warming up the seas a bit more by building pipelines, buying into more explosive methane (*), and encouraging fracked gas people to export? What could it hurt? There are many alternatives, most sketched here on this blog. … Continue reading
Update: 20th June 2016 “Rising seas: Should I say or should I go?“, by Delavane Diaz WunderBlog.
Happy Vernal Equinox! This post has been updated today with some of the equations which correspond to the models. An assessment of whether or not there was a meaningful slowdown or “hiatus” in global warming, was recently discussed by Tamino … Continue reading
Like Sankey diagrams, causal diagrams are a useful tool to assess and communicate complicated systems and their intrarelationships: It’s possible to use these for analysis and prescription: Here is the (promised) presentation on reenforcing loops: So how can these techniques … Continue reading

sonnenCommunity connects households and makes conventional electricity suppliers obsolete through self-generated power
Sonnenbatterie presents the sonnenCommunity; members can generate their own power, store it and share surpluses online with friends or each other. The sonnenCommunity completely replaces traditional power companies and will soon be available to every household in Germany. – sonnenCommunity … Continue reading
What will the energy landscape look like after utility companies are either dead, dying, or revert to a tiny portion of their territory? Silicon Valley CCE Partnership gives us all a clue. It’s been described in the San Francisco Chronicle, … Continue reading
In a decision by the New York State Public Service Commission on 16th October 2015, ceilings on the interconnection of distributed generation by sources like residential solar PV, sometimes called “caps”, were indefinitely suspended for all utility companies in the … Continue reading
New research published today projects a doubling of surface melting of Antarctic ice shelves by 2050 and by 2100 may surpass intensities associated with ice shelf collapse, if greenhouse gas emissions from fossil fuel consumption continues at the present rate. … Continue reading
Like most mammalian tissue, tumors often produce shards of DNA as a byproduct of cell death and fracture. This circulating tumor DNA is being studied as a means of detecting tumors or their resurgence after treatment. (See also a Q&A … Continue reading
As I have mentioned before, it’s so nice that Nature and probability bend to the whims of property developers and their Town Fathers, with the willing participation of the Federal Emergency Management Agency (FEMA). If you had property at risk … Continue reading

Incredible Rainfall In South Carolina, and Yes Climate Played A Role – Dan’s Wild Wild Science Journal – AGU Blogosphere
Make no mistake, this was a flood event unlike any other in South Carolina and while Hurricane Joaquin never hit the coast, it holds a smoking gun. This flood was the result of several factors, an … Source: Incredible Rainfall … Continue reading

We fully expect utilities and regulators to make a good faith effort to preserve the status quo “regulatory compact,” whereby the monopoly utility provides a safe and reliable service and regulators allow it to earn a reasonable low-risk return. However, … Continue reading
Abstract Recent estimates of the global carbon budget, or allowable cumulative CO2 emissions consistent with a given level of climate warming, have the potential to inform climate mitigation policy discussions aimed at maintaining global temperatures below 2° C. This raises … Continue reading
