Denitrifying bacteria and hungry plants do sterling work in disposing of the nitrates that we pump into rivers and streams.

Do the math: affordable new technologies can prevent global warming while fostering growth. March 2008

Trees are not very effective as carbon sinks trees may not be the insurance against global warming we all thought they were. Their ability to store carbon dioxide has diminished due to rise in

Stabilization of atmospheric CO2 concentrations below a pre-industrial doubling (~550 ppm) is a commonly cited target in climate policy assessment. When the rate at which future emissions can fall is assumed to be fixed, the peak atmospheric concentration –

The forest biome of Amazonia is one of Earth's greatest biological treasures and a major component of the Earth system. This century, it faces the dual threats of deforestation and stress from climate change. In this article, the authors summarize some of the latest findings and thinking on these threats, explore the consequences for the forest ecosystem and its human residents, and outline options for the future of Amazonia.

The consequences of global climate change are profound, and the scientific community has an obligation to assess the ramifications of policy options for reducing greenhouse gas emissions and enhancing CO2 sinks in reservoirs other than the atmosphere. Ocean iron fertilization (OIF), one of several ocean methods proposed for mitigating rising atmospheric CO2, involves stimulating net phytoplankton growth by releasing iron to certain parts of the surface ocean.

Agriculture is one of the largest emitters of greenhouse gases. Greenpeace's new report Cool Farming details the destructive practices resulting from industrial agriculture and presents workable solutions to help reduce its contribution to climate change. These practical changes will benefit the environment as well as farmers and consumers throughout the world. This report details for the first time all direct and indirect contribution agriculture has on climate change.

there has been a 35 per cent increase in carbon dioxide emissions worldwide since 1990. Inefficient fossil fuels have contributed to a 17 per cent increase in carbon dioxide emissions and an 18 per

Environmental groups have condemned an Australian company's plan to dump tonnes of urea into Philippine waters as part of an experiment called ocean fertilization to combat climate change. The

At a meeting of world mangrove experts held last year in Australia, it was unanimously agreed that we face the prospect of a world deprived of the services offered by mangrove ecosystems, perhaps within the next 100 years. Mangrove forests once covered more than 200,000 km2 of sheltered tropical and subtropical coastlines.
