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.)

CARBON-DIOXIDE HIGHEST IN 800,000 YEARS

ScienceDaily reports that the study of Antarctic ice-cores has established that the present concentration of carbon-dioxide is higher than it has been at any time during the past 800,000 years. It is now a bit more than 380 parts per million, compared to a range of about 200-300 parts per million during that time. The current concentration of methane is 1,800 parts per billion, compared to a range of about 400-700 parts per billion during that time.
