Jennie was watching on the news that they ran out of limos over at the Copenhagen conference and that even though public transport was provided for the conference attendees, they didn't use it.  Also, the airport is so overpacked with all the private jets that were flown to the conference that they are having to fly to other regional airports or Sweden to park. 

She's had the solution for global warming awhile, but has kept it quiet.  It's very simple: everyone worried about global warming needs to stop breathing. 
Obviously, if they're not breathing, they won't be exhaling carbon dioxide every few seconds.  As an added bonus, since they'll die, they won't need to fly all those private jets or use all those limos!  I bet that would solve the problem once and for all! 

The only problem with the solution is that they're isn't a way to make money off of it.  But that's all right.  I also suspect that she had an affair with Tiger Woods, crashed the White House party, and is somehow involved in that hacked data that resulted in Climategate.  As soon as I get some proof, she'll be all over the news.....I'll be able to buy a ton of cat treats with the tell-all book she'll be able to write. 

Off to dig through her e-mail again...the proof is there somewhere...I know it.
