The world's leaders and environmentalists are meeting in Cancun, Mexico this week for the U.N. Climate Summit.
It's the first global gathering on the topic since last year's Climate Change Conference in Copenhagen, Denmark.
Expectations are scaled back this year after the Copenhagen conference was unable to produce any major binding international policy changes.
Just as with the Copenhagen conference, a group of University of Minnesota students are at the international climate change gathering this year in Cancun.
Andy Pearson is senior at the university who is in a class on climate change policy. He joined All Things Considered host Tom Craan by phone from the summit.
