Hydropower: More than just a barrier to fish migration - Science for Environmental Policy - [You must be registered and logged in to see this link.] - Despite the numerous benefits of hydropower, this renewable energy source can have serious negative consequences on the environment. While dams have been known for some time to act as a barrier to migration of organisms, new research shows that they also affect water temperature and silt build-up in downstream river stretches. The research also suggests that short-term peaks in water flow, which occur when hydropower plants are operating, also have a negative impact on fish and their habitat. - 31 January 2007.

Land Clearing and the Biofuel Carbon Debt - Increasing energy use, climate change, and carbon dioxide (CO2) emissions from fossil fuels make switching to low-carbon fuels a high priority. Biofuels are a potential low-carbon energy source, but whether biofuels offer carbon savings depends on how they are produced. Converting rainforests, peatlands, savannas, or grasslands to produce food-based biofuels in Brazil, Southeast Asia, and the United States creates a ‘biofuel carbon debt’ by releasing 17 to 420 times more CO2 than the annual greenhouse gas (GHG) reductions these biofuels provide by displacing fossil fuels. In contrast, biofuels made from waste biomass or from biomass grown on abandoned agricultural lands planted with perennials incur little or no carbon debt and offer immediate and sustained GHG advantages. - Science Express - Published Online February 7, 2008 - Joseph Fargione, Jason Hill, David Tilman, Stephen Polasky, Peter Hawthorne.

Sea level rise by 2100 'below 2m' - [You must be registered and logged in to see this link.] - By Richard Black Environment correspondent, BBC News website - Sea levels globally are very unlikely to rise by more than 2m (7ft) this century, scientists conclude. - Major increases would have to be fuelled by a faster flow of glaciers on the Greenland or Antarctic ice sheets. - But writing in the journal Science, a US team concludes that a rise of 2m would need glaciers to reach speeds that are "physically untenable". - However, even increases substantially less than 2m would cause major issues for many societies, they say. - 4 September 2008.
