Troy's Scratchpad

About

For Climate Science Analysis and WIPs

Yes, I am yet another software engineer with a climate science blog.  My hope here is to keep the focus technical and away from the drama we find on other climate sites in the blogosphere.  While that drama can be entertaining in its own right, there are plenty of other places to find it.

Besides — and I know I’m not the first person to say this — it’s a lot easier to publish a general comment attacking politics, motivations, or even a broad scientific topic, than it is to make a specific and coherent technical argument.

  2. Glad to see another techie taking a whack at sorting out the CS mess. Which the cAGW crowd have sadly poliiticized, imo. Looking forward to spending some time here —

  3. I may use your Humidity1.jpg from Aug 2010 in one of my forthcoming papers on ‘thermal wastes’ and their global antrhopogenic warming. I would like your permission [copyrights] to do so. I have found a method to calculate the specific humidity increases – using simple heat balance physics – comparing observed global mean atmospheric [surface] temperatures with anthropogenic waste heat generated. I appreciate your explanations in the recent posts [July 2014] on radiative forcings and calculations on temperature increases..using the sensitivity approaches. We have a simple heat transfer model for global anthropogenic warming and is approved for publication in an energy journal in September – which discusses the role of water vapor.

    • You are welcome to use that image. However, as there is no reference in that image to the humidity data (it is referenced in the text above), and it is a fairly simple plot from that data,you would likely be better off simply generating your own image from that data.

  4. Thanks. I saw the data – I will try and construct the graphs as necessary. I also found specific humidity info at 3 different altitudes.You may like sensitivity analysis of global energy budgets by Knutti’s group – by N.Schaller, et al,

    Neelameggham and Davis, Heat Transfer Modeling of Global Anthropogenic Warming is accepted for publication by the Journal of Nanomaterials and Energy. This heat balance model considers only the warming effects caused by human energy conversion waste heat – since 1965.. which assigns excess heating than observed surface temperature increase of 0.7 o C to water and ocean surface evaporation into increasing specific humidity .. this is about 1000 +/- 250 ppm depending on energy conversion inefficiencies [which is all a thermal waste known to heat atmospheric air]. We use principles of heat transfer by path of least resistance – which incidentally fits the climate scientists approach of intially assuming ‘heat capacity of earth is zero’ [Manabe and Wetherald 1967], or ‘slab ocean’ with zero heat transport to ocean [initially] [noted in T. Schneider, 2009].
