3  attempt to prove that carbon dioxide is a greenhouse gas  learn a bit (more) about world energy use  learn a bit (more) about climate change  measure our individual carbon footprints, and learn how to reduce them

20  The scientists: hundreds of scientists all over the world contribute to the work of the IPCC as authors contributors and reviewers.

21  “Most of the observed increase in globally-averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG concentrations.”

28 “moose mortality is increasing because of winter ticks…. these insects can remove more protein than a moose can take in," Jakubas said. “It was not unusual last fall to count more than 100,000 ticks on a young moose.” -Wally Jakubas (Maine IF&W) http://bangornews.com/news/t/news.aspx?articleid=150974 &zoneid=500 http://www.chrisharris.com/gallery/g-bull-moose.jpg
