New research that involves NCAR's Bette Otto-Bliesner questions conventional wisdom with regard to massive iceberg discharges in the North Atlantic Ocean during the last glacial period, pointing toward climate rather than ice sheet instability as a cause.
A new study involving NCAR's Bette Otto-Bliesner looks at rising sea levels during the warmth of the last interglacial period (130,000 to 120,000 years ago) and finds that melting ice sheets contributed far more to rising sea levels than thermal expansion.
If you’re an American, it’s tough to avoid corn. This ubiquitous starch turns up in soft drinks, compostable cups, and automobile fuel—and even plays a role in U.S. heat waves, including the intense one of 2011.
The Sun drives our climate, so a slowdown in solar activity would surely put the brakes on global warming—wouldn’t it? That question percolated through the media following a set of reports from a solar physics meeting.
A new study led by NCAR’s Wei Yu and CU-Boulder’s Weiqing Han looks at the effects of the Madden-Julian Oscillation (MJO), the largest source of intraseasonal (within one season) variability in the tropics, causing wet and dry periods to alternate.
It’s been two decades since NOAA launched its Climate and Global Change Postdoctoral Program. The C&GC program was created in response to a lack of trained specialists, and it’s kept up with continued expansion in climate change study.
A new study looks at how the anticipated recovery of the ozone hole over Antarctica and simultaneous increase in greenhouse gas concentrations will combine to affect weather and climate in the Southern Hemisphere.
Alaska is among the fastest-warming places on Earth, with its interior region warming the most statewide. A study by NCAR’s Shannon McNeeley looks at the vulnerability to climate change of native rural communities.
Like a creature from a hydrologic horror flick, Devils Lake, North Dakota, has been expanding off and on for 70 years, most dramatically from the mid-1990s onward. Some of its tendrils have blocked rail lines and roadways for years.
When climate change leaped into global consciousness more than 20 years ago, there was no doubt that sea levels would rise, but the main worry was how those rising seas would affect civilization, not on how the oceans themselves might be transformed.
A study led by NCAR postdoctoral researcher Jia Hu and Julia Klein from Colorado State University looks at the relationship between plants, water, carbon, and climate on the Tibetan Plateau, which is warming at a rate twice that of the global average.
Last year, a team of NCAR scientists verified that the Weather Research and Forecasting model (WRF) can be used to depict seasonal snowfall in Colorado with a high degree of accuracy. Now the team is using WRF to forecast future snowfall.
Strong jet streams often plow into the West Coast in wintertime, but the heaviest rains and snows occur when the flow dips far south over the Pacific, allowing it to bring an atmospheric river of warm, moist air from the subtropics to California.
