Yes, I will be marching for Science in Boston

Posted on 8 March 2017 by ecoquant

Like many, including Eli Rabett, I will be marching for Science in April, on Earth Day. My march will be part of the Boston march. Why? Because Science has been and is my life, and it always has been, and … Continue reading →

Polls, Political Forecasting, and the Plight of Five Thirty Eight

Posted on 18 October 2016 by ecoquant

On 17th October 2016 AT 7:30 p.m., Nate Silver of FiveThirtyEight.com wrote about how, as former Secretary of State Hillary Clinton’s polling numbers got better, it was more difficult for FiveThirtyEight‘s models to justify increasing her probability of winning, although … Continue reading →

`Hermine Unique among Storms’

Posted on 4 September 2016 by ecoquant

Originally posted on Climate Denial Crock of the Week:
Hermine still developing. Predictions are for it to hold in place off the East Coast for several days, due to a blocking pattern known as a “Rex Block”.  This and many…

A model of an electrical grid: A vision

Posted on 3 August 2016 by ecoquant

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 →

“Full-depth Ocean Heat Content” reblog

Posted on 28 July 2016 by ecoquant

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 →

“Number density, not mixing ratio”, from Eli

Posted on 11 April 2016 by ecoquant

From this post: There is a cute little number called Loschmidt, the number of molecules in a cubic meter of air at 1 atm and 0° C, 2.6867774(47) x 1025 molecules/m3 … Eli Rabett provides a neat way to see … Continue reading →

Southern Oscillation (SOI) correlated with Outgoing Longwave Radiation (OLR)

Posted on 12 November 2015 by ecoquant

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 →

What it takes to power a (light) bulb, and Sankey Diagrams

Posted on 20 October 2015 by ecoquant

Kevin Anderson has a chart he uses to argue for demand-side reduction of energy use as a powerful way to achieve emission reductions of greenhouse gases. That chart is: It is derived from the IPCC AR4 Working Group 3 Report, … Continue reading →

No turning back: On the effectiveness of artificially removing emitted CO2 from atmosphere for remediating climate disruption

Posted on 16 September 2015 by ecoquant

Your future: Antarctica, in detail

Posted on 18 August 2015 by ecoquant

Climate and geophysical accuracy demands fine modeling grids, and very large supercomputers. The best and biggest supercomputers have not been available for climate work, until recently. Watch how results differ if fine meshes and big supercomputers are used. Why haven’t … Continue reading →
