Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by NCAR. The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050. Boulder, CO (PRWEB) May 05, 2014 Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National...

Star known as HD49933 is located 100 light years away from Earth In a bid to unlock long-standing mysteries of the sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star. By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the sun's solar cycle. Results of the study, conducted by scientists at the U.S. National Center for Atmospheric Research (NCAR) in Boulder, Colo., and...

Such burns release less carbon dioxide than wildfires, scientists find The use of prescribed burns to manage western forests may help the United States reduce its carbon footprint. Results of a new study find that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size. "It appears that prescribed burns can be an important piece of a climate change strategy," says Christine...

Computer model simulates impact of white roofs on urban areas Painting the roofs of buildings white has the potential to significantly cool off cities and mitigate some impacts of global warming, results of a new study indicate. The research, the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide, suggests there may be merit to the idea of turning roofs white. But the study team, led by scientists at the National Center for Atmospheric Research...

Operators of satellites, weather instruments may receive early alerts An innovative computational technique that draws on statistics, imaging and other disciplines has the capability to detect errors in sensitive technological systems ranging from satellites to weather instruments. The patented technique, known as the Intelligent Outlier Detection Algorithm, or IODA, is described this month in the Journal of Atmospheric and Oceanic Technology. IODA offers the potential to alert operators to...

Researchers reported on Thursday that plants stressed by drought or unseasonable temperatures squirt out an aspirin-like chemical that may be a sort of immune response that helps protect the plants, the scientists speculated.The finding raises the possibility that farmers, forest managers and others may eventually be able to start monitoring plants for early signs of a disease, an insect infestation or other types of stress, they said.Currently they often do not know if an ecosystem is...

June 29, 2005 BOULDER"”Wildfires in Alaska and Canada in 2004 emitted about as much carbon monoxide as did human-related activities in the continental United States during the same time period, according to new research by the National Center for Atmospheric Research (NCAR). The fires also increased atmospheric concentrations of ground-level ozone across much of the Northern Hemisphere. The NCAR study, which indicates the extent to which wildfires contribute to atmospheric pollution,...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
