Global Warming Is Changing Organic Matter In Soil: Atmosphere Could Change As A Result

Marcos     Clima Eventos     0

-11.28.08- Scientists at the University of Toronto Scarborough have published research findings in the journal Nature Geoscience that show global warming actually changes the molecular structure of organic matter in soil. “Soil contains more than twice the amount of carbon than does the atmosphere, yet, until now, scientists haven’t examined this significant carbon pool closely,” says Myrna J. Simpson, principal investigator and Associate Professor of Environmental Chemistry at UTSC. Leer más

Endangered sea turtles killed by cold snap

Marcos     Clima Eventos     0

-11.27.08- Every year, endangered sea turtles wash up on the beaches of MassachusettsCape Cod Bay, freezing and near death. Most are nursed back to health. This fall, though, an unusually early, long cold snap and lashing winds have caused more Kemp’s Ridley sea turtles, the most endangered sea turtles in the world, to wash ashore dead, says Tony LaCasse, spokesman for the New England Aquarium in Boston, which rehabilitates sick turtles and returns them to the wild.

Forests May Play Overlooked Role In Regulating Climate

Marcos     Clima Eventos     0

-11.25.08- When sunlight reaches the Earth’s surface it can either be absorbed and converted to heat or reflected back to outer space, where it doesn’t influence the Earth’s temperature. Scott Ollinger, a professor at the UNH Institute for the Study of Earth, Oceans, and Space and the department of Natural Resources and the Environment, and colleagues have discovered that, of the total amount of sunlight that falls on forests, the fraction that gets reflected back to space is directly related to levels of nitrogen in their foliageLeer más

Denmark Works To Cut Carbon Dioxide Emissions By 50%

Marcos     Clima Eventos     0

-11.26.08- For two days 160 scientists, businesspeople and government officers have been working to answer the question: What is the fastest way to an energy system with much less CO2 emissions? The first step is to integrate an interconnected intelligent power grid in Europe. Denmark can become independent of fossil fuels by implementing efficiency improvements in all sectors including power stations, houses, industry and transport. At the same time, the share of renewable energy must be increased with more wind energy and increased use of biomass. In the transport sector we can replace fossil fuels with biofuels and we can also use electric cars which can be integrated into the power gridLeer más
