Although they are related, meteorology and climatology have important differences, particularly in how scientists develop and use weather and climate models. What makes climatologists think they can project climate scenarios decades into the future when meteorologists cannot accurately predict weather more than two weeks in advance? This presentation by Wayne Higgins of NOAA's Climate Prediction Center clarifies the relationships and differences between weather and climate, as well as the differences between natural climate variability and human-induced climate change.

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

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.

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.

An expert on climate conditions in East Africa describes the climate factors behind the 2011 drought, which has contributed to food insecurity and famine.

For decades, the City of Boulder, Colorado, has been successfully managing its water supply despite the challenges of being located in a semi-arid climate. But a local water manager wonders if climate change will change the rules of the game...

Christopher Landsea, of NOAA’s National Hurricane Center, works with tropical storm data and other hurricane experts to figure out how our warming world will affect hurricanes. Find out what current research tells us about hurricanes in the future.
