A Modtran Mystery

Guest Post by Willis Eschenbach I’ve been messing about with the “Modtran” online calculator for atmospheric absorption. It’s called “Modtran” because it is a MODerate resolution program to calculate atmospheric infrared absorption written in ForTRAN, which calculates the result for each 1 … Continue reading

Video: Comments on Human-Induced Global Warming – Episode 1 – The Hiroshima Bomb Metric

With much fanfare from the faithful (a grand total of 15 comments as of this writing), SkepticalScience recently released their 4-Hiroshima-Bombs-per-second widget. Their claimed intent is to “raise the awareness of global warming”. Nonsense. Their intent is to scare people—children … Continue reading

Climate science and nuclear weapons research: Another conflation of weather and climate

From The Bulletin of the Atomic Scientists via SAGE Publications  comes this press release claiming that because nuclear fallout was tracked by meteorological instrumentation and synoptic scale models, it somehow relates to climate science. I think it’s a stretch. About … Continue reading
