Wheat production would be reduced by rising temperatures
September 5, 2013 06:04 AM - ScienceDaily
Any producer will tell you, growing a healthy, high-yielding wheat crop takes skill and hard work. Quality drought-tolerant varieties that are resistant to pests and disease are important. And cooperation from Mother Nature in terms of temperature and precipitation doesn't hurt, either. To quantify the impact of genetic improvement in wheat, disease and climate change over a 26-year period, a team of researchers at Kansas State University examined wheat variety yield data from Kansas performance tests, along with location-specific weather and disease data. Their results showed that from 1985 through 2011, wheat breeding programs boosted average wheat yields by 13 bushels per acre, or 0.51 bushel each year, for a total increase of 26 percent.
Proof Clean Air Act Has Reduced Pollution
September 4, 2013 03:30 PM - Editor, ENN
Before 1970, there was no law in place regulating the amount of pollution that could be emitted by any single entity. However, in 1970, the Clean Air Act was passed and today there is clear evidence that it has indeed helped to reduce pollution.
A Tsunami in Philadelphia?
September 4, 2013 06:06 AM - Roger Greenway, ENN
Could the city of Philadelphia get hit by a Tsunami? It's not in a coastal environment, and even if it were, the eastern US is not exactly the earthquake capital of the world. Good thing that the US Geological Survey thinks about such things. A newly published paper concludes that a modest (one-foot) tsunami-like event on the East Coast was generated in the past by a large offshore earthquake. This result may have potential ramifications for emergency management professionals, government officials, businesses and the general public. Early in the morning of Jan. 8, 1817, earthquake shaking was felt along the Atlantic seaboard as far north as Baltimore, Md., and at least as far south as Charleston, S.C. Later that morning, a keen observer documented an abrupt rise in the tide on the Delaware River near Philadelphia, commenting on the earthquake felt earlier to the south, and remarking that the tidal swell was most likely "the reverberation or concussion of the earth operating on the watery element."
Children and the Environment: How gardening lessons impact positively on school kids
September 3, 2013 12:03 PM - Camilla Scaramanga, The Ecologist
Pending reforms to the UK's school curriculum mean that from September 2014, pupils aged 7-14 can expect to learn gardening skills. Camilla Scaramanga takes a look at some of the initiatives that are already taking the lead... Growing food in schools looks set to become part of the curriculum starting from September 2014, furthering the positive impacts of those very successful initiatives already working to promote gardening and 'grow your own' schemes in schools nationwide. There are currently 4,500 schools enrolled on the Food for Life Partnership plan (FFLP) and figures show that twice as many schools received an outstanding OFSTED rating after working with the Food for Life partnership. In addition, the uptake of free school meals in FFLP schools has risen by an average of 13%.
Rhode Island school sets an example in waste reduction
September 3, 2013 06:23 AM - KEVIN PROFT/ecoRI News
Sophia Academy is an all-girls middle school on Branch Avenue with less than a hundred students. During the 2011-12 school year, the academy’s 62 girls sent 10,000 Styrofoam lunch trays to the landfill. "We did some simple 'tray math' in class," said Alyssa Wood, science teacher at the school. Wood had her students multiply the 180-day school year by the 62 students enrolled at Sophia Academy, almost all of whom receive a free or reduced lunch. The students were amazed by the result, she said.
Oceanic plume of radioactivity predicted to reach US by 2014
September 2, 2013 06:21 AM - JEREMY HSU, LIVESCIENCE.COM via Discovery News
A radioactive plume of water in the Pacific Ocean from Japan's Fukushima nuclear plant, which was crippled in the 2011 earthquake and tsunami, will likely reach U.S. coastal waters starting in 2014, according to a new study. The long journey of the radioactive particles could help researchers better understand how the ocean’s currents circulate around the world. Ocean simulations showed that the plume of radioactive cesium-137 released by the Fukushima disaster in 2011 could begin flowing into U.S. coastal waters starting in early 2014 and peak in 2016. Luckily, two ocean currents off the eastern coast of Japan — the Kuroshio Current and the Kuroshio Extension — would have diluted the radioactive material so that its concentration fell well below the World Health Organization’s safety levels within four months of the Fukushima incident. But it could have been a different story if nuclear disaster struck on the other side of Japan.
EV Tax incentives can't last forever
August 31, 2013 07:31 AM - MOVEFORWARD, Electric Forum
At this moment in time there seems to be no stopping the electric vehicle industry which is going from strength to strength. Sales are increasing, more automobile manufacturers are joining the party and motorists seem more at ease with electric vehicles there than they ever have been. While one of the reasons the industry has been kick started over the last couple of years is tax incentives and financial incentives some governments around the world, would you still buy an electric vehicle with no tax incentives today? The likelihood is that the vast majority of EV enthusiast would not buy an electric vehicle today without the tax incentives and financial attractions offered by governments around the world. This is an industry which is still very much in its infancy, the technology is still developing and perhaps many people are still yet to fully appreciate the impact which petrol/gasoline vehicles have upon the environment.
Deadly effects of air pollution detailed in MIT study
August 29, 2013 06:02 AM - Roger Greenway, ENN
We know that pollution is bad for us, don't we? And we guess that living in areas with high levels of pollution is probably not good for our health, but we need to live near our job, and populated areas offer more employment opportunity, recreational and cultural opportunities and other advantages. But at what cost? And what can we do to reduce the levels of pollution without significantly changing the life styles we have all become accustomed to? Before we consider draconian changes, we would like to know just how bad it is. Researchers from MIT's Laboratory for Aviation and the Environment have come out with some sobering new data on air pollution's impact on Americans' health. The group tracked ground-level emissions from sources such as industrial smokestacks, vehicle tailpipes, marine and rail operations, and commercial and residential heating throughout the United States, and found that such air pollution causes about 200,000 early deaths each year. Emissions from road transportation are the most significant contributor, causing 53,000 premature deaths, followed closely by power generation, with 52,000.
Turn ON the dark!
August 28, 2013 06:14 AM - Paul Bogard, Yale Environment360
As evidence mounts that excessive use of light is harming wildlife and adversely affecting human health, new initiatives in France and elsewhere are seeking to turn down the lights that flood an ever-growing part of the planet. Last month, France — including the City of Light — grew darker late at night as one of the world's most comprehensive lighting ordinances went into effect. From 1 a.m. to 7 a.m., shop lights are being turned off, and lights inside office buildings must be extinguished within an hour of workers leaving the premises. The lighting on France’s building facades cannot be turned on before sunset. Over the next two years, regulations restricting lighting on billboards will go into effect. These rules are designed to eventually cut carbon dioxide emissions by 250,000 tons per year, save the equivalent of the annual energy consumption of 750,000 households, and slash the country’s overall energy bill by 200 million Euros ($266 million).
New report calls for immediate action to tackle aviation emissions
August 27, 2013 08:56 AM - ClickGreen Staff, ClickGreen
A new scientific report released today highlights the critical importance of taking early action when implementing measures to reduce the climate impact of rapidly increasing emissions from aviation. With a decision expected shortly on how and when to tackle international aviation emissions, today's report increases the pressure on the International Civil Aviation Organization (ICAO) (the United Nations agency responsible) not to defer a decision on the adoption of a market-based measure (MBM).
