Students with the Campus Climate Challenge at the University of Maryland-College Park this week participated in the national week of action to raise awareness about global warming. Volunteers set up a table at the annual Stampfest in the Student Union and collected more than 300 photo petitions, asking Congress to "Step it up: cut carbon dioxide 80% by 2050." In addition, students set up the table with a laptop showing an Inconvenient Truth on a loop to all who stopped by the table.
