In October 2003, a little-known think tank in the Department of Defense quietly released a report warning that climate change could happen so suddenly it could pose a major threat to our country's national security. Why was the Pentagon worried about abrupt climate change? Because new evidence from Greenland showed it had happened before.
Social scientist and communication expert Mathew Nisbet makes the case that endless debates about whether or not global warming is really happening have grown stale and miss the point entirely. Shouldn't we be talking about how society can leverage climate science in ways that save lives and natural resources and create new markets for jobs and services?
Climate scientist Michael MacCracken explores some of the scientific, legal, and ethical implications of "geo-engineering" options that have been proposed by some people to address global climate change.
The types of tree species that grow in a particular region determine the range of bright colors that paint our landscapes during the fall season. In the future, scientists project that the forest habitats all around us may undergo major changes to due to warming temperatures.
C-Learn is a simplified version of the C-ROADS simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.
