Asteroid Caused Massive Firestorm Leading To Global Extinction
2013-03-28 05:17:03

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Colorado claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet´s species. According to Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences (CIRES) and colleagues, the firestorm...

Global Warming Slowed By Volcanic Sulfur Dioxide
2013-03-02 06:44:51

[ Watch the Video: What is Global Warming ] redOrbit Staff & Wire Reports - Your Universe Online Global warming was slowed between 2000 and 2010 because of sulfur dioxide spewed forth by volcanoes, researchers from the University of Colorado Boulder (CU-Boulder) and the National Oceanic and Atmospheric Administration (NOAA) claim in a new study. Some experts had blamed China and India for the phenomenon, as both countries increased their industrial sulfur dioxide emissions by an...

Areas of Bendable Ice Help Support Antarctic Ice Shelf
2012-12-09 06:42:36

redOrbit Staff & Wire Reports - Your Universe Online The largest remaining Antarctic ice shelf contains several cracks and crevasses that could make it prone to collapse, but also areas in which different types of frozen water blend together to create areas of bendable ice that help hold it together, according to a new study presented late last week. Experts at the University of Colorado, Boulder's Cooperative Institute for Research in the Environmental Sciences (CIRES) discovered...

Summers Are Getting Warmer
2012-11-13 20:13:21

Lee Rannals for redOrbit.com — Your Universe Online According to a new study published in the journal Geophysical Research Letters, summer climates in regions across the globe are mostly warming. Scientists from the Cooperative Institute for Research in Environmental Sciences headquartered at the University of Colorado Boulder performed an analysis of 90 years of observational data to reveal how the summers are changing. "It is the first time that we show on a local scale that...

One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models, according to a new University of Washington study. The finding is important because it helps confirm that models that simulate global warming agree with observations, said Stephen Po-Chedley, a UW graduate student in atmospheric sciences who wrote the paper with...

Ocean Found To Be Surprising Source Of Arctic Methane
2012-04-23 03:49:05

The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study by Eric Kort of NASA's Jet Propulsion Laboratory, Pasadena, Calif., has uncovered a surprising and potentially important new source of Arctic methane:...

A University of Colorado Boulder-led team has developed a new monitoring system to analyze and compare emissions from man-made fossil fuels and trace gases in the atmosphere, a technique that likely could be used to monitor the effectiveness of measures regulating greenhouse gases. The research team looked at atmospheric gas measurements taken every two weeks from aircraft over a six-year period over the northeast United States to collect samples of CO2 and other environmentally important...

The exhaust fumes from gasoline vehicles contribute more to the production of a specific type of air pollution-secondary organic aerosols (SOA)-than those from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA's Earth System Research Laboratory (ESRL) and other colleagues. "The surprising result we found was that it wasn't diesel engines that were contributing the most to the organic aerosols in LA,"...

The past decade has witnessed a significant growth in Asian air pollution, causing a great concern for air quality and climate. If government policy makers hope to contain the problem, they will need increased research and better computer models of black carbon and other aerosol pollutants, also known as atmospheric brown cloud (ABC), according to University of Iowa engineering professor Gregory Carmichael. Carmichael made the case for more research and better-informed policy makers when...

Recent cuts to the scientific workforce of Environment Canada, a government agency responsible for meteorological services and environmental research, threaten scientific research related to the ozone layer in the upper atmosphere and pollution in the lower atmosphere, according to environmental scientists in the U.S. These reductions in personnel and projected budget cuts also threaten existing international agreements. "Canada is a bellwether for environmental change, not only for Arctic...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
