Although global grain production must double by 2050 to address rising population and demand, new data from the University of Illinois suggests crop yields will suffer unless new approaches to adapt crop plants to climate change are adopted. Improved agronomic traits responsible for the remarkable increases in yield accomplished during the past 50 years have reached their ceiling for some of the world's most important crops. "Global change is happening so quickly that its impact on...

Human-driven changes in the earth's atmospheric composition are likely to alter plant diseases of the future. Researchers predict carbon dioxide will reach levels double those of the preindustrial era by the year 2050, complicating agriculture's need to produce enough food for a rapidly growing population. University of Illinois researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in...

Chemicals that helped solve a global environmental crisis in the 1990s "” the hole in Earth's protective ozone layer "” may be making another problem "” acid rain "” worse, scientists are reporting. Their study on the chemicals that replaced the ozone-destroying chlorofluorocarbons (CFCs) once used in aerosol spray cans, air conditioners, refrigerators, and other products, appears in ACS' Journal of Physical Chemistry A, a weekly publication. Jeffrey Gaffney, Carrie J....

FARMINGTON, Conn., May 28 /PRNewswire/ -- Twenty-five years ago this month, three scientists published an article in Nature magazine alerting the world to the discovery of a hole in the Earth's stratospheric ozone layer. This discovery triggered action by governments, industry, and environmentalists around the world and contributed to the Montreal Protocol agreeing to phase-out the production and consumption of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) used as...

The eruption of the volcano in Iceland has drawn attention to air flow patterns, as airlines lost millions of dollars and travelers remained stranded for days to weeks, as particles from the natural disaster traveled over Europe, forcing closures of major airports. The flow of particles, although seemingly random, can be characterized more effectively, according to work done by Virginia Tech's Shane Ross of the engineering science and mechanics (ESM) department and his colleague Francois...

Kudzu, an invasive vine that is spreading across the southeastern United States and northward, is a major contributor to large-scale increases of the pollutant surface ozone, according to a study published the week of May 17 in the journal Proceedings of the National Academy of Sciences. Kudzu, a leafy vine native to Japan and southeastern China, produces the chemicals isoprene and nitric oxide, which, when combined with nitrogen in the air, form ozone, an air pollutant that causes...

Proposals Would Tackle HFCs at Montreal Protocol, Reap Huge Climate Benefits WASHINGTON, April 30 /PRNewswire-USNewswire/ -- The State Department announced the formal submission of two proposals by Canada, Mexico and the U.S. seeking action to phase down global production and use of hydrofluorocarbons (HFCs) under the Montreal Protocol. If agreed to by other nations, an international phase down of these powerful greenhouse gases (GHG) could begin almost immediately. The nation of...

A new NASA study of Earth's polar ozone layer reinforces scientists' understanding of how human-produced chlorine chemicals involved in the destruction of ozone interact with each other. A team of scientists led by Michelle Santee of NASA's Jet Propulsion Laboratory, Pasadena, Calif., examined how nighttime temperatures affect chlorine monoxide, a key chemical involved in ozone destruction. Combining NASA satellite measurements with a state-of-the-art chemical model, they found this...

BELLINGHAM, Wash., April 27 /PRNewswire/ -- Captain Ozone allegedly started the modern-day "real-life superhero" movement when he made his debut in 1989. He's considered by many to be the most phenomenal environmental activist of all time. Captain Ozone is saving endangered species, promoting renewable energy and ecological art, and also teaching school kids how to become environmental activists on television. The masked man claims to be from the year 2039 and he time-traveled to 1989...

SILVER SPRING, Md., April 13 /PRNewswire-USNewswire/ -- The U.S. Food and Drug Administration today announced, in accordance with longstanding U.S. obligations under the Montreal Protocol on Substances that Deplete the Ozone Layer, seven metered-dose inhalers (MDI) used to treat asthma and chronic obstructive pulmonary disease (COPD) will be gradually removed from the U.S. marketplace. These inhalers contain ozone-depleting chlorofluorocarbons (CFCs), which are propellants that move...
