James Roger Fleming presents a historical perspective on how our understanding of Earth's climate system developed through innovations and discoveries by pioneering scientists in the 1800s and 1900s who asked and answered fundamental questions about the causes and effects of global climate change.

Deke Arndt, chief of NOAA's Climate Monitoring Branch, presents the preponderance of scientific evidence that climate change is occurring and that humans are the primary cause.

"Climate Science 101" short course sponsored jointly by the Osher Lifelong Learning Institute (OLLI), at George Mason University, and NOAA.

Claudia Mengelt and Robert Fri talk about strategies for adapting to and reducing global climate change.

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.

Climate scientist Anthony Janetos makes it clear that climate change isn't some future abstraction: real and substantial impacts on people's lives, the economy, the environment, and our valuable natural resources are already happening here in the United States.

Humans currently release about 70 million tons of carbon dioxide every day into the atmosphere and about 20 million tons is being absorbed regularly by the oceans, causing the pH to drop.  Chris Sabine describes current and projected future impacts of this acidification on marine ecology.

Jim Wilczak describes the information NOAA provides to guide optimal wind energy development.

Felix Kogan talks about using satellites to observe and forecast the climate conditions that lead to mosquito–and malaria–outbreaks.
