There's major disagreement among scientists on exactly what might be causing a tendency toward colder winters over the last few years in places like the central and eastern United States, Europe, and Russia.
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.
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.
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.
Researchers are finding new ways to work with aspects of climate change that are surprisingly linear, an approach that could help save time and money in future climate research while providing a richer range of information to help guide policy.
A field project this June and July will study gravity waves, towering atmospheric features little-known to the public. Novel instruments to be deployed for the international DEEPWAVE project, based in New Zealand, will provide an unprecedented view of gravity waves, a major shaper of atmospheric variability at multiple heights.
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.
