    Aw, shucks. When I saw "Mosquito Driver" I was hoping you had a De Havilland Mosquito (first picture). The only Mosquito I've ever flown was a Glasflügel Mosquito (second picture). Welcome anyway, and how about posting a photo of yours?

  • If you think 12-15 microns is a microwave region, that would explain why you keep getting the wrong answer on this issue, but I think you probably really do know how to interpret the numerical scales on those charts, could comprehend how a sensitive balance can be upset by changing even one component...

  • And if we didn't have an atmosphere at all, we'd be cooked by 1.4 kW/m^2 (all wavelengths). But it's the balance that matters, not the amount reflected away. And that balance is affected by IR transparency in the 12,000 to 15,000 nm range, where CO2 is very, very important.. Look how close the CO2...

  • "Most people" who really want to understand will recognize that (1) the variation with wavelength is significant, with CO2 more opaque at least in the IR range I mentioned above, and (2) that the earth radiates lots of IR energy there. It is the balance between solar radiation received and...

  • Transparency is a function of wave length, and CO2 is much more opaque than water vapor in important wave length ranges, e.g. 12,000 to 15,000 nm....

  • On a scale of hundreds of millions of years, "climate" as argued here, is meaningless (the typical time scale used in the literature under discussion is a 30 year width interval, not millions of years). The Sahara is thought to go from lush to desert on a cycle more like 40,000 years, which...

  • The existence of prior climate changes doesn't mean that man is incapable of influencing climate now. I'm pretty sure that Neanderthals weren't burning fossil fuel at our rates. We've gone through about 1.5 trillion barrels of oil, 300 billion tons of coal, and 130 trillion cubic meters of natural...

  • Meanwhile, the Himalayas are getting taller, the Alps are holding steady, and the Appalachian mountains are eroding away. Looking at one spot doesn't say much about planet-wide sea level behavior....

  • The obvious difference is that "truth" in religion is a highly personal matter judged by laymen on the basis faith and belief. Science is not a matter of faith or belief, nor does it depend upon the opinions of laypeople. It works by observational evidence and expert evaluation of objective...

  • So now we have citations to two climate dissenters. They remain a tiny minority.

  • You cut off the first part of my sentence when you quoted it. I started it with this:

    There are always dissenters in science (just look at the research about the health effects of smoking) but...

    The climate dissenter you cite (who, by the way, also questions any link between...

  • It's strange how recollection is so very personal, and so varied. My recollection is that the ozone depletion danger was recognized and timely international action was taken in the 1980s-90s (banning CFCs in aerosols, air conditioners, etc,. through the Montreal Protocol), without a partisan political...

  • The just-discontinued Volt is not an electric car. It is a plug-in hybrid with a 1.5 liter piston engine driving a generator; it's electric-only range is roughly 30 miles. Chevy's recent all-electrics are the Bolt (238 mile range) and through 2016 the Spark EV (replaced by the Bolt). Hybrid sales...

  • You really should drive one of the modern all-electrics before passing judgment.
    In just my own circle of friends at the local indoor rock climbing gym, there are owners of an Audi A3-etron, a BMW I3, a Chevy Spark, a Nissan Leaf, a Fiat 500e, and a couple of Tesla 3s. The owners love them because...

  • The IPCC didn't exist until 1988, with no assessments until 1990, and of course there were no computer models in 1940 for predictions.
    Are you asking if they calibrate their current models using historical data?...

    Now I have to wonder where you're getting that data.


    The first half dozen fatality reports I checked (the most recent) all show Mac engines. The older ones don't specify because the report formats are more cursory. I don't doubt that as Doug suggests, offset redrives made things...

  • This same issue has cropped up in the investigation of the recent Lion Air Flight 610 Boeing 737 MAX crash. Here's some text from an Aviation Week electronic newsletter about the investigation:

    Like all turbofan-powered airliners in which the thrust lines of the engines pass below the center...

    I put category "gyoplane", severity "fatal", and model "B8M" into the NTSB database search tool, and 47 deadly accidents popped up right away. I suspect that other combinations of search terms (e.g., Bensen, fatal) would produce more, and that some never made it into the...
