NOTE ON POPULAR POSTS

The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

And at the 20km mark there were extremely high levels of ozone-destroying chlorine chemicals. Scientists say that levels of the nasty chemicals peaked in 2001. This latest peak, between September the 21st and 30th, must not have read their report. They also expect the ozone-layer to make a slow recovery and be back to normal in about 2065...

Keep the sunblock handy. In New Zealand the UV level is at 9, out a of a possible 10.
