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.

NCAR has implemented an enhanced data sharing service that allows scientists increased access to data as well as improved capabilities for collaborative research.

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.

Known from their frequent film and TV appearances, the large, charismatic birds are in danger. By 2100, according to a new study, their numbers will have fallen by around 19% and will continue to decline, qualifying the species for endangered status.

The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global yields of corn and wheat because of warming temperatures.
