Establishing a key link between the solar cycle and global climate, new research led by the National Center for Atmospheric Research (NCAR) shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Niña and El Niño events in the tropical Pacific Ocean.
In a breakthrough that will help scientists unlock mysteries of the Sun and its impacts on Earth, an international team of scientists led by NCAR has created the first-ever comprehensive computer model of sunspots.
Melting of the Greenland ice sheet may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and Canada.
The largest and most ambitious tornado study in history will begin next week, as dozens of scientists deploy radars and other ground-based instruments across the Great Plains to gain a better understanding of these often deadly weather events.
As part of its Walter Orr Roberts Distinguished Lecture series, UCAR will present a special lecture next week by NASA scientist James E. Hansen, one of the nation's most respected experts on climate change.
NCAR and its managing organization, UCAR, announced today the selection of an architectural design team for a supercomputing center dedicated to advancing scientists' understanding of climate, weather, and other Earth and atmospheric processes.
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.
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?
UCAR, working with an international team of health and weather organizations, is launching a project this month to provide long-term weather forecasts to medical officials in Africa to help reduce outbreaks of meningitis.
Schoolchildren, families, and citizen scientists around the world will gaze skyward after dark from October 20 to November 3, looking for specific constellations and then sharing their observations through the Internet.
