Last month I was interviewed by the NewlyGreens and it aired on WPSC 88.7 out of Wayne, NJ broadcasting over New Jersey and New York.

You can listen to the interview here.

Image appears to be related to Wolfe et al. (1997). Also available in Schubert and Turcotte below the discussion. Image found at LDEO.

I took the time this weekend to re-create a Google Earth layer showing these data. This visualization allows you to see a broad geospatial overview, and then select any particular location and see both long-term trends and even the data point for each individual month.

The reader should be able to understand the dominant causes of past climate change and to critically evaluate the projections of climate change over the next centuries or millennia. The book is also intended to give the student the bases to understand how climate models are built and how they could be used to make quantitative estimates of climate variability and climate change, as well as to illustrate how models could be used to understand the most important concepts of climate science.

It should be interesting to see what type of suits get filed, both legitimate and silly, and the type of payouts involved. Maybe some of the money could even go to those affected, or to solving the problem, rather than the lawyers…

I’ve heeded the Gore call to action (pics) in the past. As I write this I’m debating if I’m willing to chain myself to something and get arrested for this cause. I am aware that any future astronaut applications would be disqualified by this action.

I just found some old (1973) global climate model (GCM) documentation lying around the office. The document describes the GISS GCM at some stage between the UCLA parent and Model I. Model I evolved into Model II which became the foundation for EdGCM. I have scanned the document and submitted it to the History of Atmospheric GCMs website.

It is a beautiful document describing all aspects of the GCM: Numerics and dynamics, punch cards, grid schemes, physical equations, tables and tables of variables and units, etc. These two images (click for large version) show the punchcard order for the old GCM, and the grid scheme at the poles. I like the pole graphic because it reminds me of last year when I was at the South Pole.

The oldest paper I know of that discusses human induced climate change is from 1896, by Svante Arrhenius, titled On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground (PDF, 4413KB).

@article{Arrhenius:1896b,
        Author = {Svante Arrhenius},
        Journal = {Philosophical Magazine and Journal of Science},
        Month = {April},
        Number = {41},
        Pages = {237 -- 276},
        Title = {{On the Influence of Carbonic Acid in the Air
                upon the Temperature of the Ground}},
        Volume = {5},
        Year = {1896}}

@manual{Tsang:1973,
        Author = {L. C. Tsang and R. Karn},
        Month = {October},
        Institution = {Goddard Institute for Space Studies},
        Organization = {Computer Science Corporation},

1) Open Google Earth. Make sure you have Terrain turned on (bottom left panel) and optionally, turn up the vertical exaggeration (Preferences)

2) Select the Add menu then Polygon

3) On the map window, draw a box around your region of interest. Four clicks works optimally

4) In the Info window, enter a description

5) Select the Altitude tab

6) Enter the desired sea level rise (1-7m)

7) Select Absolute

8) Select OK to close the Info window

Your layer is now complete.
