I’m beginning a new style of column, called technical publications of the week. While I can’t promise these will be weekly, I will, from time to time, highlight technical publications I’ve recently read which I consider to be noteworthy. I … Continue reading
Zeke Hausfather at And Then There’s Physics regarding Baselines and Buoys.
I have made an important update to an earlier post here, Getting back to 350 ppm CO2: You can’t go home again. The message, essentially based upon recent work Tokarska and Zickfield on one hand, and by The Global Carbon … Continue reading
There is an excellent piece in Ars Technica about why scientific measurements need to be adjusted, and the implications of this for climate data. It is written by Scott K Johnson and is called “Thorough, not thoroughly fabricated: The truth … Continue reading
From WGBH, and hat tip to Environmental Justice TV, includes Dr Gavin Schmidt speaking, who I was especially interested in, and whose talk begins here: Interesting that Dr Schmidt has some gentle criticism of the PBS program NOVA. Whole talk … Continue reading
From Katharine Hayhoe, who I deeply respect, and from John Cook (*), scientists and the quantitative community have been scolded that the reason they don’t make headway with the public and the science denier community is because their explanations are too … Continue reading
When knowledge conquered fear … And, what better way to celebrate than watching the National Geographic Cosmos episode, When knowledge conquered fear, hosted by the great Dr Neil deGrasse Tyson, Director of the Hayden Planetarium in New York City.
The National Center for Atmospheric Research (“NCAR”) reports on a newly substantiated teleconnection between positive sea surface temperature anomalies (“SSTA”) in the Pacific and the temperatures over the continental United States (“CONUS”) 50 days later. A teleconnection is: A linkage … Continue reading

Trump’s supporters cannot change natural reality, even through Trump; we can and should continue to act, in hope
I like his emphasis upon Remember residual damage, and that’s There’s no rewind button. That’s Alex Steffen, who has the most optimistic post-Trump spiel I’ve read. And there’s always the optimism that comes with China’s warning Trump about not taking … Continue reading
Just a couple of things to write about The Obvious. I have written a couple of longer thoughts as Comments, here and here, at … And Then There’s Physics. I reiterate that I don’t believe any voter was hoodwinked, that … Continue reading
Hint: Climate change has somethin’ to do with it. Schematic diagram illustrating the component parts of the AMOC and the 26◦ N observing system. Black arrows represent the Ekman transport (predominantly northward). Red arrows illustrate the circulation of warm waters … Continue reading
Professor David Titley (see also, and here) writes in the online newsletter DefenseOne: Many observers think climate change deserves more attention. They might be surprised to learn that U.S. military leaders and defense planners agree. The armed forces have been … Continue reading
BlackRock, the world’s largest private investment fund, has announced that it will include climate change as an important factor in how it assigns risks to its investment portfolio … BlackRock is not your average investment fund. With $4.9 trillion in … Continue reading

An Executive Order, No. 569 ESTABLISHING AN INTEGRATED CLIMATE CHANGE STRATEGY FOR THE COMMONWEALTH WHEREAS, climate change presents a serious threat to the environment and the Commonwealth’s residents, communities, and economy; WHEREAS, extreme weather events associated with climate change present … Continue reading
Dr Schmidt is essentially betting that the trend, seen as a random variable, will regress towards the smooth mean. I have a post at Nate Silver’s 538 site on how we can predict annual surface temperature anomalies based on El … Continue reading
Alerted to the existence of the image by Tamino. The figure is due to the irrepressible Randall Munroe.
A post from one of my favorite statistics-oriented bloggers, Variable Variability, dealing with a subject too casually passed over. See Naïve empiricism and what theory suggests about errors in observed global warming.
Bill Nye hosts Dr Neil deGrasse Tyson‘s Star Talk Radio, featuring climate change and NASA’s Dr Gavin Schmidt. (See also RealClimate.)
Carbon Sinks in Crisis — It Looks Like the World’s Largest Rainforest is Starting to Bleed Greenhouse Gasses

I’m currently studying random walk and diffusion processes and their connections with random fields. I’m interested in this because at the core of dynamic linear models, Kalman filters, and state-space methods there is a random walk in a parameter space. … Continue reading
The Bayesian blocks algorithm of Scargle, Jackson, Norris, and Chiang has an enthusiastic user community in astrostatistics, in data mining, and among some in machine learning. It is a dynamic programming algorithm (see VanderPlas referenced below) and, so, exhibits optimality … Continue reading
This is a re-blog of an excellent post at And Then There’s Physics, titled Full-depth OHC or, expanded, “full-depth ocean heat content”. Since my holiday is now over, I thought I might briefly comment on a recent paper by Cheng … Continue reading
I made a comment on Google+ pertaining to a report of a recent NOAA finding. Enjoy. But remember that COP21 boundary is equivalent to 450 ppm CO2.
