Ok, looks like life is moving in a more blog-friendly way. So I'll hang out the shingle again for your questions, suggestions, comments.
In the mean time, I'll note a few additions and losses. Among the losses is that the blogger widget for showing the 10 most recent comments is broken. You can still subscribe to the comments. My notes about sites which seem to be inactive, but which have material you can still read and is worth reading, are now a 'page' -- one of the tabs near the top of the page, so a loss and an addition.
Also added to the tabs near the top are "The Simplest Climate Model", and "What is Climate?", which collect in one place, finally, the several posts I've made on each topic. There'll be more.
