Over millions of years carbon dioxide levels in the atmosphere have been moderated by a finely-tuned natural feedback system- a system that human emissions have recently overwhelmed.
As part of its Sustainable Computing Program, Microsoft Corp. today announced it will support four academic research projects focused on energy efficiency in computing in the areas of datacenter power efficiency, power management and the creation of parallel computing architecture with decreased power demands.
An international collaborative of scientists led by Peter Niiler, a physical oceanographer at Scripps Institution of Oceanography, UC San Diego, and Nikolai Maximenko, a researcher at the International Pacific Research Center, University of Hawaii, has detected the presence of crisscrossing patterns of currents running throughout the world's oceans.
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity. The finding underscores the benefits of biodiversity, such as capturing carbon dioxide, a main contributor to global warming.
Recent advances in technology have made removing salt from seawater and groundwater a realistic option for increasing water supplies in some parts of the U.S., and desalination will likely have a niche in meeting the nation's future water needs, says a new report from the National Research Council.
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them.
In 1970, Kermit the Frog (voiced by Jim Henson) crooned, "It's not that easy being green, having to spend each day the color of the leaves."
Increased carbon dioxide in the Earth's atmosphere is causing microscopic ocean plants to produce greater amounts of calcium carbonate (chalk) - with potentially wide ranging implications for predicting the cycling of carbon in the oceans and climate modelling.
Today, three top environmental experts addressed reporters, calling attention to the serious consequences of Congressional food-to-fuel mandates on the environment, world hunger, and American consumers. The experts also urged Congress to revisit these policies.
Given the global consensus on climate change, world leadership has looked at growth in India and China with increasing alarm. The prior experience of industrially-developing countries worldwide would suggest that as an economy grows, it consumes more and more energy. Given currently available energy and technology options, this in turn leads to increased carbon emissions into the environment.
