Global Hot Air?

I am preparing a talk for a high school science class tomorrow morning. The topic that has everybody in awe is alternative energy. As a chemist, i have some different opinions on climate science and global warming - especially concerning the IPCC proclamations of science by political committee. Here is a different reactionary viewpoint. Somewhere between is a likely scenario. As a disclaimer - i work with folks from the Umpqua Bio-Alternative Cooperative looking into biomass to oil issues, so i am not a totally disinterested information source. Mebbe not so reactionary, eh?

Chemical bonds store energy, whereas human bonding requires energy for storage for later use, when the going gets hard. I am interested in the feedback that i will get by allowing the students to explain their ideas before we start dissecting the reading material. This is like - Forensics 101 - who heated the earth. Not really - this talk will be more about the methods we use to know the information, and how we might attempt to collect data. Just gotta make sure the audience is interested and on the same general page.
