I’ve got a couple of articles going up at New Scientist. Here is the first:

Carbon dioxide may be the lead cause of global warming, but other gases are more potent greenhouse agents. So what is it about these molecules that makes them such effective heat trappers?

A team at NASA think they know, and the work could be used to create more environmentally friendly materials.

Timothy Lee and his colleagues at the Ames Research Center in Sunnyvale, California, analysed the physical and chemical properties of powerful greenhouse gases called fluorocarbons. They discovered that molecules containing fluorine atoms are particularly effective at trapping heat, especially when many fluorine atoms are bonded to a single carbon atom, which is the case with fluorocarbons.
