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.
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.
