The deadly heat wave that crippled Russia last summer was due to a natural atmospheric phenomenon often associated with weather extremes and not directly caused by global warming, according to a new study by the National Oceanic and Atmospheric Association (NOAA). And while the scientists could not attribute the intensity of the Russian heat wave to climate change, they did find that extreme heat waves are likely to become more frequent in the region in the coming decades. The researchers...

Up to two-thirds of Earth's permafrost likely will disappear by 2200 as a result of warming temperatures, unleashing vast quantities of carbon into the atmosphere, says a new study by the University of Colorado Boulder's Cooperative Institute for Research in Environmental Sciences. The carbon resides in permanently frozen ground that is beginning to thaw in high latitudes from warming temperatures, which will impact not only the climate but also international strategies to reduce fossil fuel...

New dataset provides understanding of Earth's past and future climate From the hurricane that smashed into New York in 1938 to the impact of the Krakatoa eruption of 1883, the late 19th and 20th centuries are rich with examples of extreme weather. Now an international team of climatologists have created a comprehensive reanalysis of all global weather events from 1871 to the present day, and from the earth's surface to the jet stream level. The 20th Century Reanalysis Project, outlined in the...

A novel project using cameras mounted on unmanned aircraft flying over the Arctic is serving double duty by assessing the characteristics of declining sea ice and using the same aerial photos to pinpoint seals that have hauled up on ice floes. The project is the first to use aircraft to monitor ice and seals in remote areas without putting pilots and observers at risk, said Elizabeth Weatherhead of the University of Colorado at Boulder, who is leading the study team. Weatherhead is a senior...

Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change, according to a new study involving the University of Colorado at Boulder. The new study showed ice sheets like the Greenland Ice Sheet can respond to such warming on the order of decades rather than the centuries projected by conventional thermal models. Ice flows more readily as...

A thick blanket of yellow haze hovering over Houston as a result of chemical pollution produced by manufacturing petroleum products may be getting a little bit thinner, according to a new study.But the new findings -- which have implications for petrochemical-producing cities around the world -- come with a catch, says a team of scientists from the Cooperative Institute for Research in Environmental Sciences, or CIRES, a joint institute of the University of Colorado at Boulder and the...

The large number of tiny organic aerosols floating in the atmosphere "“ emitted from tailpipes and trees alike "“ share enough common characteristics as a group that scientists can generalize their makeup and how they change in the atmosphere. The groundbreaking research by Colette Heald, assistant professor in the Department of Atmospheric Science at Colorado State University, was highlighted this month on the cover of the American Geophysical Union's prestigious Geophysical...

Using skills passed down through generations, Inuit forecasters living in the Canadian Arctic look to the sky to tell by the way the wind scatters a cloud whether a storm is on the horizon or if it's safe to go on a hunt. Thousands of miles away in a lab tucked in Colorado's Rocky Mountains, scientists take data measurements and use the latest computer models to predict weather. They are two practices serving the same purpose that come from disparate worlds. But in the past 20 years,...

Mass media have been a key vehicle by which climate change contrarianism has traveled, according to Maxwell Boykoff, a University of Colorado at Boulder professor and fellow of the Cooperative Institute for Research in Environmental Sciences, or CIRES. Boykoff, an assistant professor of environmental studies, presented his research today at the annual meeting of the American Association for the Advancement of Science in San Diego. He spoke during a panel discussion titled "Understanding...

Pollution from Asia is causing ozone levels to rise above the western United States, an increase that could make it more difficult for the U.S. to meet Clean Air Act standards for ozone pollution at ground level, according to an international study published on Wednesday. The study, published in the journal Nature, analyzed large sets of ozone data captured since 1984. It focused primarily on data for ozone in springtime above western North America at an altitude of between two and five...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
