Climate impacts in northern forests
Northern forests hold around 54% of the world’s total terrestrial carbon stock and contribute more than one-third to our global terrestrial carbon sink. This report reviews the impact of human induced

Can coal live up to its clean promise?
Coal is our cheapest and most abundant source of fossil-fuel energy. We probably have enough to keep the world powered for hundreds of years.

Stream denitrification across biomes and its response to anthropogenic nitrate loading
Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing and terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more bioavailable nitrogen to enter grou

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

Trees are not very effective carbon sinks
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

Atmospheric stabilization and the timing of carbon mitigation
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

Climate change, deforestation and the fate of the Amazon
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.

Ocean iron fertilization-moving forward in a sea of uncertainty
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.

Cool farming: climate impacts of agriculture and mitigation potential
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.

Carbon dioxide emissions on a 35 per cent high
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
