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.)

CLIMATE THREAT FROM HFCs

<a href="http://www.bbc.co.uk/news/science-environment-15818659">The BBC reports</a> on growing concerns that ozone-friendly HFCs are not friendly to climate-change, because the average global warming potential of the present mix of HFCs is about 1600--so a kilogram of HFC has about 1600 times the effect on global warming as a kilogram of carbon dioxide.

The HFCs: A Critical Link in Protecting Climate and the Ozone Layer, a report produced by the UN Environment Programme (UNEP), projected that the global warming potential of HFCs in 2050 could be comparable with present emissions from the global transport sector.
