China: Greener than you think
August 22, 2008 08:38 AM - , SciDevNet
China may have guzzled a lot of carbon in its 30 years of industrialisation, but it could achieve a clean energy miracle in the next 30, argues Wu Changhua in New Scientist.
Current climate models 'ignoring brown carbon'
August 18, 2008 10:50 AM - , SciDevNet
Scientists have found that air pollution from East Asia contains an abundance of 'brown carbon' particles and say that atmospheric models need updating to incorporate their effect. Current climate models take into account two types of aerosol carbon — organic carbon and black carbon — that arise from the burning of fossil fuels or biomass.
China ventures into carbon capture
August 11, 2008 10:38 AM - , SciDevNet
China and Australia will test a post-combustion capture (PCC) pilot plant in Beijing as part of a plan to cut carbon dioxide emissions from thermal power stations. The plant, officially announced last week (31 July), is a collaboration between the China HuaNeng Group, the country's largest power producer, and Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO).
Malaria cannot be halted on its own
August 6, 2008 11:35 AM - , SciDevNet
Concentrating efforts on malaria alone is unlikely to sustain malaria control or achieve its eradication, say Peter J. Hotez and David H. Molyneux in PLoS Neglected Tropical Diseases. They suggest an integrated approach, linking malaria and neglected tropical diseases (NTDs). Together malaria and the seven most common NTDs cause two million deaths a year.
China's Olympian efforts to tackle air pollution
August 6, 2008 11:17 AM - , SciDevNet
As the 2008 Beijing Olympic Games get underway, an expensive environmental experiment is taking place, providing a golden opportunity for pollution science. The Beijing Olympic Air Quality Monitoring and Warning Project, a 30 million yuan (US$4.3 million) monitoring system, has been created in an attempt to guarantee clear skies for the games.
Kenyan courts consider terminating biofuel plans
August 6, 2008 08:49 AM - , SciDevNet
The Kenyan courts are considering halting the first stage of a US$370 million biofuel project that aims to replace up to 20,000 hectares of coastal grassland with irrigated fields of sugarcane. A judicial review of the project, based at the Tana River Delta on the northern Kenyan coast, was granted last month (11 July) after a campaign from environmental groups such as Nature Kenya and the East Africa Wildlife Society,and nomadic cattle-farming groups. The project is intended to generate electricity — up to 34 megawatts a day at its peak — from sugar refining and up to 20 million litres of ethanol fuel annually from molasses.
Tibetan plateau melts in the face of climate change
August 5, 2008 12:11 PM - , SciDevNet
Climate change is affecting the Tibetan plateau, threatening regional water supplies and altering atmospheric circulation for half the planet. The plateau is the world's third largest store of ice. But its temperature has risen by up to 0.3 degrees Celsius every ten years over the last fifty years — approximately three times the global warming rate.
Wetlands 'must be preserved' say experts
July 30, 2008 08:59 AM - , SciDevNet
Participants in an international wetlands conference have issued a declaration urging recognition of the importance of wetlands and calling for basic wetlands research.
Peru mountain glaciers 'receding rapidly'
July 29, 2008 12:00 PM - , SciDevNet
Climate change-induced glacier melts have cost northern Peru's mountains 26 per cent of their surface area in the last 33 years, satellite images have confirmed.
African scientists to trial GM tobacco to smoke out landmines
July 28, 2008 10:05 AM - , SciDevNet
South African researchers are working on a genetically engineered tobacco plant that turns red near land mines — offering a potentially cheap way to clear post-conflict zones.
