Ozone pollution in India is damaging millions of tons of the country’s major crops, according to a new study by an international team of researchers. The pollution caused losses of more than $1 billion in a single year, destroying enough food to feed an estimated 94 million people.
For millions of people, El Niño or La Niña indicates whether they’re likely to face unusually warm, cold, wet, or dry conditions over the coming winter. A new modeling study pins down the process that apparently determines why La Niña events often last twice as long as typical El Niño events—a result with major implications for seasonal predictions.
A leading goal of solar scientists is to improve predictions of the Sun's approximately 11-year cycle. New research led by scientists from NCAR and Sweden shows how solar predictions can borrow from weather forecasting techniques in order to predict the timing and extent of the solar cycle.
Scientists have found that internal variability can make one season twice as active as another, even when large-scale hurricane-shaping elements are unchanged. The research suggests that seasonal hurricane forecasts could be improved by conveying the amount of unavoidable uncertainty in the outlook.
California will likely experience more large fires in forested areas this century because of rising temperatures and changes in precipitation along with development patterns, new research finds. The blazes could increase some types of fire-generated air pollution by more than half.
Geophysical Research Letters, a leading journal in Earth science, is toasting its 40th anniversary this month with an editor-picked retrospective collection of 40 papers, including several with authors from NCAR.
Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts.
