Alex Steffen on Climate Defeatism

On 31st July 2018, Alex Steffen wrote (on Twitter) that: Reminder that climate defeatism—arguing that we are already so screwed that there’s no real point in acting to limit climate emissions or ecological damage—is absolutely a form of denialism, and … Continue reading

Sampling: Rejection, Reservoir, and Slice

An article by Suilou Huang for catatrophe modeler AIR-WorldWide of Boston about rejection sampling in CAT modeling got me thinking about pulling together some notes about sampling algorithms of various kinds. There are, of course, books written about this subject, … Continue reading

forecast for 27th March 2018

Today is the 21st of March, 2018. We are supposed to get our fourth nor’easter tomorrow this late Winter, and the third nor’easter in nearly as many weeks. ECMWF hosted, in this incarnation, at the Meteocentre UQAM in Montreal created … Continue reading

Less evidence for a global warming hiatus, and urging more use of Bayesian model averaging in climate science

(This post has been significantly updated midday 15th February 2018.) I’ve written about the supposed global warming hiatus of 2001-2014 before: “‘Overestimated global warming over the past 20 years’ (Fyfe, Gillett, Zwiers, 2013)”, 28 August 2013 “Warming Slowdown?”, Azimuth, Part … Continue reading

NCAR reports on a teleconnection between the Pacific and continental USA

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

David Puttnam, in a moving appeal on climate

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

TOO LATE: “There will be no golden age of [natural] gas”

Last month, Tom Randall at Bloomberg New Energy Finance (“BNEF”) profiled a new forecast which shows costs for zero Carbon energy and energy are plummetting so fast that coal, oil, and natural gas will begin their terminal decline within a … Continue reading

A model of an electrical grid: A vision

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

Phytoplankton-delineated oceanic eddies near Antarctica

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
