There’s a discussion way off at Energy Institute at Haas about how unfair solar owners are, under current government policies, to electrical customers who do not have PV accessible. It’s irrelevant. Fossil fuels are done, stranded, the walking dead. Boss … Continue reading
On Sunday, 11th February 2018, I presented an Abstract of a 3 hour talk on the subject, “Carbon emissions and climate: Where do we stand, and what can be done if it all goes wrong?” at the Needham Lyceum, hosted … Continue reading
Drs Carol Anne Clayson and Alec Bogdanoff examined evaporation from the ocean surface and energy exchange at the boundary layer of the ocean surface, respectively. See also the interactive illustration here. (The above is from Dr Carol Anne Clayson’s personal … 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
David Puttnum (yes, the producer-director) has a very moving appeal on climate: Hat tip to Tamino. President Lyndon Johnson was the first to receive a briefing regarding the looming crisis presented by abrupt climate change. That was in 1965. And … Continue reading

I went to some Departmental talks recently and discovered that some of my colleagues are researchering possible carbon sequestration technologies. This could be very important, but appealing to negative emission technologies is…
Many people seem to view the electrical grid of the future being much like the present one. I think a lot about networks, because of my job. And I especially think a lot about network topologies, although primarily concerning the … 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.
With regard to my comment at hypergeometric | July 13, 2016 at 3:50 pm on Tamino’s blog, someone challenged me on my assertion “Believe me, the +3C-+4C worlds are not places we want to go!” there. I have replied at … Continue reading
“The Myth of the 1970s Global Cooling Scientific Consensus“, T. C. Peterson, W. M. Connolley, J. Fleck, http://dx.doi.org/10.1175/2008BAMS2370.1. Abstract Climate science as we know it today did not exist in the 1960s and 1970s. The integrated enterprise embodied in the … Continue reading
Excerpt, from NASA: Phytoplankton are the grass of the sea. They are floating, drifting, plant-like organisms that harness the energy of the Sun, mix it with carbon dioxide that they take from the atmosphere, and turn it into carbohydrates and … Continue reading
The UNFCCC’s COP21 concluded goals which aimed for limiting global warming to C, and certainly keeping it below C, both measured with respect to pre-industrial temperatures. Bad news. According to the United States National Center for Atmospheric Research (“NCAR”), in … 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
November Hottest Ever, and Christmas Likely To bring Record Warmth in The East (Dan’s Wild Wild Science Journal; AGU Blogosphere)
The long-range guidance is showing strong indications that the incredible December warmth in the Eastern U.S. will continue to the end of the month. A blast of cold air will arrive later this week,… (Click on image for larger map, … Continue reading
Click the image above to see a video from the GFDL CM2.6 climate model. This is NOT this year’s El Nino. When you start a climate model in which the ocean and the land and atmosphere can inte… Source: El … Continue reading
Good to review the basics once again. Professors Dave Archer and Ray Pierrehumbert do, in my opinion, some of the best introductions: Infrared radiation and planetary temperature.

To the climate community this is nothing at all new, but I spotted these time series today and thought they would make a nice exhibit on how something people have direct control over, greenhouse gas emissions, affect a “teleconnection mechanism” … Continue reading
Part 1 of this series introduced the idea of ctDNA and its use for detecting cancers or their resurgence, and proposed a scheme whereby relative concentrations of ctDNA at two or more sites after controlled disturbance might be used to … Continue reading
Eli condenses the problem with the Carbon Cycle and excessive emissions of fossil fuel CO2 to a few paragraphs, a great figure, and a trio of linear differential equations.

Lead article in the San Francisco Chronicle today addresses how non-solar customers of Pacific Gas & Electric are already carrying a larger burden of the network costs for that utility, costs which are reflected in their rates. This is the … Continue reading
New Paper Shows Global Climate Model Errors are Significantly Less Than Thought (Dan’s Wild Wild Science Journal)
New Paper Shows Global Climate Model Errors are Significantly Less Than Thought – Dan's Wild Wild Science Journal – AGU Blogosphere. The paper is here, unfortunately behind a paywall. I wonder if they looked at the temperature distributions’ second moments? … Continue reading
