The National Climate Assessment assesses the science of climate change and its impacts across the United States, now and throughout this century. It documents climate change related impacts and responses for various sectors and regions, with the goal of better informing public and private decision-making at all levels.

This collection of activities is based on a weekly series of space science problems distributed to thousands of teachers during the 2009-2010 school year. They were intended for students looking for additional challenges in the math and physical science curriculum in grades 9 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be ‘one-pagers’ with a Teacher’s Guide and Answer Key as a second page. This compact form was deemed very popular by participating teachers.

This 3-activity sequence addresses the question: "To what extent should coastal communities build or rebuild?" The activity uses social science and geoscience data to prepare an evidence-based response to the question, in targeted US coastal communities.

What are the two biggest threats facing future generations? The growing Federal debt, and climate change. The national debt will trash the economy, and global warming will trash the planet. But economics offers a solution to BOTH problems: a carbon tax. So why do economists cry themselves to sleep?
