Colorado flood: flood waters in south Boulder, Colorado, September 12, 2013
August 26, 2014
Almost a year after Colorado’s deadly and destructive floods of September 2013, a group of NCAR scientists has just completed testing an innovative new system for detecting and predicting torrential rainfall as well as the risk of local flooding.
Penguins and climate change: emperor penguins and chicks at Snow Hill Island, Antarctica, October 2009

In recent years, spring snow has vanished even more quickly than computer models and climate scientists had expected, posing a research challenge and a potentially serious risk for water supplies.
Plowing snow in New Hampshire: How do cold winters and climate change intersect?
March 04, 2014
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?
Midwest cold wave: Ice fog in frigid air produces sun dogs
January 14, 2014
Last week’s Arctic outbreak brought some of the coldest air in decades across the U.S. Midwest and South. But interestingly, it didn’t last as long as historic cold waves of the late 20th century.
Drought puts California water supply at risk: Photo of Lake Mead, Nevada/Arizona
January 13, 2014
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.
Warming hiatus? Map showing changes in global temperature since late 1970s
January 08, 2014
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.
Winter cold: Student launching a weather balloon in heavy snow during OWLes project

It’s hard to escape the cold now plowing into the eastern United States. Amid all the hype, what stands out about this early winter onslaught?
Snow and the Super Bowl: Chicago's worst blizzard struck in January 1967
January 01, 2014
If the official weather forecast holds, Sunday's Super Bowl won’t have to be postponed. But the outlook would be far more uncertain if predictions today were as primitive as they were at the time of the first Super Bowl in 1967.
Can a two-week forecast warn us of Super Bowl snow? Pictured: 1950 "Snow Bowl"
January 01, 2014
Next month’s Super Bowl will be the first ever held in an open stadium in the northern U.S. What weather might we expect two weeks from now, and how might research improve a forecast in that time range?
