NCAR scientists are working on a bigger, bolder version of WACCM (the Whole Atmosphere Community Climate Model), called WACCM-eXtension, or WACCM-X for short. The enhanced version extends the model to an altitude of about 310 miles.
A team of scientists has successfully flown from the Arctic to the Antarctic this month, the first step in a three-year project to make the most extensive airborne measurements of carbon dioxide and other greenhouse gases to date.
While there has been much attention focused on the question of whether climate change influences hurricanes, scientists are also interested in whether the reverse holds true: do hurricanes significantly impact global climate?
Researchers are working toward predictions of climate change impacts in specific regions and even metropolitan areas. But are local and regional decision makers taking advantage of this science to begin to prepare for the impacts of global warming?
NCAR, working with federal agencies and universities as well as the insurance and energy industries, has launched an intensive study to examine how global warming will influence hurricanes in the next few decades.
NCAR scientists Bill Large and Steve Yeager have produced a new analysis of the exchanges of heat, momentum, and moisture between the oceans and atmosphere that should help climate modelers better assess variability on several time scales.
NCAR scientist Brian O’Neill is building an integrated assessment model to link a range of societal factors, such as future global economic and population trends, with the physical science of climate change.
Dramatic year-to-year temperature swings and a century-long warming trend across West Antarctica are linked to conditions in the tropical Pacific Ocean, according to a new analysis of ice cores conducted by scientists at NCAR and the University of Washington (UW).
Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting Earth's thermal balance. Findings will be used to improve computer models of global climate.
