Crop yields are affected by many factors, including breeding, management, and climate. New research from NCAR seeks to better understand these factors and their contributions to historical yield increases, in order to anticipate future changes.
The wolverine is known for its strength and ferocity, but these qualities cannot protect it from a warming world. NCAR research suggests that this aggressive predator may struggle to survive in the contiguous United States over the coming century.
In Kansas City and Tulsa, overnight lows have seldom dipped much below 80°F, with consistently oppressive humidity. Pulses of tropical air flowing north and east from the Gulf of Mexico are largely to blame.
During the stormy summer of 2005, hurricanes Katrina and Rita raised concerns about the potential effects of global warming on tropical cyclones. At the same time, the Amazon rainforest was experiencing one of its most intense droughts of the last century.
A study that includes NCAR scientists suggests that plant leaves emit far less methane when exposed to sunlight than previously thought. The research estimates that foliage is the source of less than 1% of Earth’s methane emissions.
Clarence Mann, University of Michigan • Mann is crossing many boundaries on the way to a master's in environmental and land use planning. His research is creating new tools for urban planners and decision makers.
The stretch of the subcontinent that runs from eastern Pakistan across northern India into Bangladesh is likely the world's most intensively irrigated region. A new NCAR study shows that between 2002 and 2008, the region depleted groundwater at a rate of around 13 cubic miles per year.
NCAR researchers are studying whether the eruption of Indonesia’s Mt. Toba supervolcano about 70,000–75,000 years ago may have cooled Earth enough to initiate an ice age and potentially alter the course of human evolution.
Lake Victoria's water levels reached a 40-year low in 2006 when East Africa was gripped by drought. A study by NCAR scientist Sean Swenson shows that drought was not the only cause of Lake Victoria's shrinkage—human management at the dam was also to blame.
In a potential boon for agriculture, a NASA-funded effort that involves NCAR and the private firm DTN/Meteorlogix has produced one of the world’s most accurate systems for predicting soil temperature up to two days in advance.
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.
Julien Wang, Significant Opportunities in Atmospheric Research and Science (SOARS) • When it came time to choose a major, Wang was torn between the arts and her growing interest in the environment. Finally, she chose environmental engineering. One recent project: designing a green roof.
