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.
Why seasonal forecasting can’t tell us with certainty what to expect this summer—and why we might soon have a stronger sense of what late 2014 and early 2015 are likely to bring to large parts of the globe.
How does the U.S. winter of 2013–14 rank against its predecessors? And was it a harbinger of more cold winters to come for parts of the country, or simply an outlier at a time of largely warming winters?
In parts of California and Oregon, 2013 was the driest calendar year on record, with no sign of relief on the horizon. NCAR scientists are examining how water and energy use intersect across this drought-prone region and how the nexus could evolve in a future climate.
The globally averaged surface air temperature hasn’t risen much in the last 15 years, but new research confirms ample heating of Earth, which becomes evident when looking at certain times of year and in particular locations, including deep in the ocean.
The Intergovernmental Panel on Climate Change released the first major segment of its new assessment report in Stockholm on September 27. Audio is now available from a teleconference with NCAR scientists and university partners, who discussed the report and took questions from the media.
Levels of carbon dioxide in the atmosphere are fluctuating more than they used to from one season to another, according to observations from the HIPPO field project. This may be a sign of significant changes in northern ecosystems.
Drier ski slopes, reduced river flows, and increased wildfires can potentially discourage tourists from coming to Colorado. Should local officials and business leaders do more to plan for these impacts?
Carbon dioxide concentrations in the atmosphere have crossed a major threshold: 400 parts per million. Here are five key points on how carbon dioxide is affecting Earth’s atmosphere and the role we're playing in it.
The last month has seen a trail of smashed records across the central United States, as pulse after pulse of cold air careened down the Great Plains. How does this fit into the bigger picture of a warming U.S. climate?
Forests across western North America have been ravaged by the most extensive bark beetle attacks on record. Scientists are getting a better handle on what comes next—and the answers aren’t as straightforward as they expected.
