1974: NCAR  1981: Hansen_etal_1.pdf    2001: Fig.A.ps     Current: Fig.A.gif

However, when I start, the overlay is not very readable and I do a lot of image processing (chroma keying and color correction) – to make the image more intelligible.

I do this using proprietary software I wrote about 10 years ago for a startup I founded in London. I’m thinking about making a simpler version for public release.

Speaking of which, I had just left London on the Underground on July 21, 2005 – when the Religion of Peace did this:

This was two weeks after the July 7 “Rivers of Blood” bombings.

This week London elected an Islamic mayor, and now they have “glory be to Allah” written on London buses.
