Goddard’s world

The blog Watts up with That is famous for its attempt to reinvent climate physics on Earth, and now they want to reinvent astrophysics as well. Steve Goddard, a frequent poster at WUWT, now has a couple of posts (here and here) as well as write ups by Lubos Motl, about how the extreme temperatures on Venus are not caused by the greenhouse effect, but rather the 90 bar atmospheric pressure on Venus. It essentially argues that the “extra warming” by that we see on Venus is mostly due to the adiabatic lapse rate. As with many posts at WUWT, this radical idea which contradicts any textbook on planetary climate has been accepted without question by most commenters. Unfortunately for the massive attempt at a paradigm shift that is underway, they are all wrong.

This is the first formal, peer-reviewed response paper to Gerhard Gerlich and Ralf Tscheuschner and their alleged greenhouse falsification. It is here toward the bottom. It does not appear too many people have easy access, so I can only suggesting contacting one of the authors (such as Prof. Halpern) for a PDF. If you leave your email address in a comment on this blog I can do it as well and it will not be published online. I also encourage discussion on this at this forum


Global Warming Maps/Graphs

Two years ago I made a post that featured a dozen or so maps and graphs that lended insight into global warming. It turned out to be one of the most read pages on my site. I now want to update that page with even better and a larger number images which are relevant to climate change. They will feature only very brief explanations. Most of what is being shown is self-evident, but if you have questions, feel free to ask them. Hopefully this can serve as a good reference for those who want some images relevant to global warming. I also recommend the site http://www.globalwarmingart.com. These images can all be clicked on for enhanced view. I am also happy to take further suggestions and them.

Greenhouse effect revisited…

Every once in a while it is worth reviewing the basic physics behind the greenhouse effect and global warming. Sometimes all the debate about global warming in the media loses focus of the fact that the world really is governed by the laws of physics. Unfortunately, many internet explanations get dumbed down to the point of having an atmosphere that serves as a single “slab” between the ground and space, and has a bunch of colorful arrows coming out of it and bouncing off it, etc. This is a useless explanation, and gives no justice to understanding what is happening. Two encounters in the outside world recently prompted me to do another post just to have a reference handy, and I’m using this to replace an older post which I entitled “just a few more molecules.” There’s also been an interesting episode with Dr. Andy Lacis from NASA GISS over at Dot Earth which I’d like to elaborate on.

Proof that the sun has been destroyed

Isotopes and Maple Syrup

I thought that this article was interesting, discussing this recent paper in the Journal of Agricultural and Food chemistry. The analysis revealed that the relative amount of carbon-13 in maple syrup have gone down since the 1970s, which they attribute to changing isotopic signatures from fossil fuel burning in the atmosphere. Discussion and implications for the food industry in the article.

Richard Alley at AGU 2009: The Biggest Control Knob

The webcast for Dr. Alley’s presentation is now up, so I recommend watching the video. It is concerning the role of CO2 on climate over geologic time.

As my own side note, Alley is one of my favorite scientists…he’s pretty much “the guy” when it comes to ice core work and has done a lot with paleoclimate (over the ice core record especially), abrupt climate change, glaciology, and sea level rise. He’s a very interesting character who always puts things in a nice perspective, and often humorous ways of teaching (e.g., his Johnny Cash geology lesson).
