For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They illustrate the complexity of climate modeling by demonstrating how natural processes still have a strong effect on the carbon cycle and climate simulations. In this case, scientists found that the rate of climate change over the next century could be higher than previously anticipated when the requirement of plant nutrients are included in the climate model. ORNL's Peter Thornton, lead author of the paper, describes the inclusion of these processes as a necessary step to improve the accuracy of climate change assessments.

California issues plan to slash greenhouse gas emissions Over the next 12 years, new regulations would seek to turn the climate change clock back to 1990 levels. More efficient electricity use, less traffic and cleaner cars are goals.

James Hansen, one of the world's leading climate scientists, will today call for the chief executives of large fossil fuel companies to be put on trial for high crimes against humanity and nature, accusing them of actively spreading doubt about global warming in the same way that tobacco companies blurred the links between smoking and cancer.

Australia is the dryest nation on earth, always was always will be, the trouble is Global warming is making the situation worse and rainfall is reducing in a disturbing pattern. For two centuries since European settlement the States have fought over 'Water-Right's' and the use of water to the detriment of the environment and ultimately to the sustainability of everyone residing here. The Murray-Darling Basin is 3,370km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia. The name of the basin is derived from its two major rivers, the Murray River and the Darling River.

The explore Team travels to India, China, Costa Rica, and the Arctic to see the impact of humanity on the planet's most important resource: water.
