Climate models need to get small
October 5, 2013 07:27 AM - Jan Piotrowski, SciDevNet
Better observational data and geographically precise climate models are needed to allow scientists to predict the effects of rising atmospheric greenhouse gas concentrations at a local level, says a major climate change report. Deficiencies in these areas prevent reliable temperature and rainfall predictions being made on a regional scale, according to the report published this week (30 September) by Working Group I of the UN's Intergovernmental Panel on Climate Change (IPCC).
Climate change could increase diarrheal disease in Botswana
October 4, 2013 01:40 PM - Bobbie Edwards, MONGABAY.COM
Climate change may increase the incidence of diarrheal disease in Botswana, according to a recent study in the International Journal of Environmental Research and Public Health. "Diarrheal disease is a very important public health problem in Botswana," said lead author Kathleen Alexander, who led a unique 30-year analysis (1974-2003) on the incidence of diarrhea in Botswana.
Australia and Canada Conservation
October 4, 2013 06:08 AM - Jeffrey Welll, The Pew Charitable Trusts, Care2
At first glance, Australia and Canada could not be more different. They are separated by more than 7,500 miles (12,000 km). One country is known for its hot, dry lands and kangaroos, and the other is known for its cold, wet forests and caribou. But at a symposium at the International Congress for Conservation Biology last July, which I co-chaired with my colleague Barry Traill, who directs The Pew Charitable Trusts' conservation work in Australia, presenters explored some interesting similarities and new ideas in conservation approaches between Australia's Outback region and Canada's Boreal Forest region. One of the reasons Traill and I were interested in comparing these two areas is because both are among the global areas identified as having the smallest "human footprint"—areas with the fewest roads, least number of people and other human-related disturbances. Another is that science and scientists have played a major role in both countries in ensuring that policymakers and the public have a clear understanding of the likely consequences that different policies could have on the biodiversity and ecological values of a region.
Phasing Down HFCs with the Montreal Protocol
October 3, 2013 03:39 PM - Mark W. Roberts and Avipsa Mahapatra, Triple Pundit
On September 27, U.S. President Barack Obama met with Indian Prime Minister Manmohan Singh to discuss how to improve ties on a number of issues between the countries, including how to support efforts to phase-down the super greenhouse gases HFCs (hydrofluorocarbons). HFCs, primarily used in refrigeration, air conditioning, and foam blowing, are extremely harmful to the climate as they are hundreds and thousands of times more potent than carbon dioxide (CO2).
An "Uncanny" Hobby
October 3, 2013 09:01 AM - David Church, The Ecologist
We all know the benefits of aluminum cans; they are light, easily moldable and can be held in a soft grip. But are they always responsibly disposed of? Can we do more to safely protect our green spaces from these metal objects? This article explores how a small scale project can help protect the local environment through recycling in the most responsible way.
Carbon credits from Mangrove preservation in Kenya
October 3, 2013 07:18 AM - Tom Marshall, Planet Earth Online
A new initiative launched today will raise money for community projects in Kenya by protecting and restoring the country's dwindling mangrove forests. The plan is to sell carbon credits earned by preserving the mangrove swamps to companies and individuals aiming to offset their carbon emissions and improve their green credentials. The scientists behind the scheme hope it will bring in some $12,000 a year, around a third of which will fund projects in areas like education and clean water. The rest will cover the cost of protecting the mangroves, as well as planting new seedlings to replace lost trees.
Land Use Study Commences at Patuxent River
October 2, 2013 03:27 PM - Robin Blackstone, ENN
An 18-month study funded through a grant from the Department of Defense (DOD) Office of Economic Adjustment (OEA) and the Tri-County Council for Southern Maryland is now underway in the area in and around the Naval Air Station (NAS) Patuxent River, Maryland. The Joint Land Use Study (JLUS) is being conducted in hopes of reducing conflict between the military installation and surrounding community while also supporting the missions and objectives of each. The Office of Economic Adjustment acknowledges that military bases and residents adjacent to military installations are often in conflict. Residents can be exposed to unacceptable noise levels and hazards and the warfighter’s training and readiness can be impaired by the normal activities of civilian life. Therefore joint planning efforts can help to resolve some of these inevitable conflicts.

Up until now, on a scale of 1 to 10, practical pest control management ranks about a "1" with regard to the availability of information on scale insects in Iran! Yet even the most basic tool for pest control management in Iran has been unavailable jeopardizing crop yields. Dr. Masumeh Moghaddam of the Iranian Research Institute of Plant Protection, Tehran has changed that by publishing the first ever detailed annotated checklist of the scale insects of Iran.
Hydrofracking resulting in radioactive contaminants in wastewater
October 2, 2013 11:52 AM - Debra Goldberg, ENN
The Marcellus Shale, encompassing 104,000 square miles across Pennsylvania, West Virginia, Ohio, and upstate New York, is the largest source of natural gas in the US. Since 2008, hydraulic fracturing has been used to release and capture the shale gas for energy consumption. The use of hydrofracking has been highly disputed, and recent findings by Duke University further display the harmful impacts of fracking.

Using two drilled core samples from northern Switzerland, researchers from the University of Zurich have unearthed flowering plant fossils dating back 240 million years. These are now the oldest known fossils of their kind. The pollen grains provide evidence that flowering plants evolved 100 million years earlier than previously thought. Researchers have described these as Angiosperm-like pollen and Afropollis from the Middle Triassic of the Termanic Basin.
